A group of diseases in which the dominant feature is the involvement of the CARDIAC MUSCLE itself. Cardiomyopathies are classified according to their predominant pathophysiological features (DILATED CARDIOMYOPATHY; HYPERTROPHIC CARDIOMYOPATHY; RESTRICTIVE CARDIOMYOPATHY) or their etiological/pathological factors (CARDIOMYOPATHY, ALCOHOLIC; ENDOCARDIAL FIBROELASTOSIS).
A form of CARDIAC MUSCLE disease in which the ventricular walls are excessively rigid, impeding ventricular filling. It is marked by reduced diastolic volume of either or both ventricles but normal or nearly normal systolic function. It may be idiopathic or associated with other diseases (ENDOMYOCARDIAL FIBROSIS or AMYLOIDOSIS) causing interstitial fibrosis.
A form of CARDIAC MUSCLE disease that is characterized by ventricular dilation, VENTRICULAR DYSFUNCTION, and HEART FAILURE. Risk factors include SMOKING; ALCOHOL DRINKING; HYPERTENSION; INFECTION; PREGNANCY; and mutations in the LMNA gene encoding LAMIN TYPE A, a NUCLEAR LAMINA protein.
A form of CARDIAC MUSCLE disease, characterized by left and/or right ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR; HYPERTROPHY, RIGHT VENTRICULAR), frequent asymmetrical involvement of the HEART SEPTUM, and normal or reduced left ventricular volume. Risk factors include HYPERTENSION; AORTIC STENOSIS; and gene MUTATION; (FAMILIAL HYPERTROPHIC CARDIOMYOPATHY).
An autosomal dominant inherited form of HYPERTROPHIC CARDIOMYOPATHY. It results from any of more than 50 mutations involving genes encoding contractile proteins such as VENTRICULAR MYOSINS; cardiac TROPONIN T; ALPHA-TROPOMYOSIN.
A congenital cardiomyopathy that is characterized by infiltration of adipose and fibrous tissue into the RIGHT VENTRICLE wall and loss of myocardial cells. Primary injuries usually are at the free wall of right ventricular and right atria resulting in ventricular and supraventricular arrhythmias.
The muscle tissue of the HEART. It is composed of striated, involuntary muscle cells (MYOCYTES, CARDIAC) connected to form the contractile pump to generate blood flow.
A disease of the CARDIAC MUSCLE developed subsequent to the initial protozoan infection by TRYPANOSOMA CRUZI. After infection, less than 10% develop acute illness such as MYOCARDITIS (mostly in children). The disease then enters a latent phase without clinical symptoms until about 20 years later. Myocardial symptoms of advanced CHAGAS DISEASE include conduction defects (HEART BLOCK) and CARDIOMEGALY.
Rare congenital cardiomyopathies characterized by the lack of left ventricular myocardium compaction. The noncompaction results in numerous prominent trabeculations and a loose myocardial meshwork (spongy myocardium) in the LEFT VENTRICLE. Heterogeneous clinical features include diminished systolic function sometimes associated with left ventricular dilation, that presents either neonatally or progressively. Often, the RIGHT VENTRICLE is also affected. CONGESTIVE HEART FAILURE; PULMONARY EMBOLISM; and ventricular ARRHYTHMIA are commonly seen.
The repeating contractile units of the MYOFIBRIL, delimited by Z bands along its length.
Inflammatory processes of the muscular walls of the heart (MYOCARDIUM) which result in injury to the cardiac muscle cells (MYOCYTES, CARDIAC). Manifestations range from subclinical to sudden death (DEATH, SUDDEN). Myocarditis in association with cardiac dysfunction is classified as inflammatory CARDIOMYOPATHY usually caused by INFECTION, autoimmune diseases, or responses to toxic substances. Myocarditis is also a common cause of DILATED CARDIOMYOPATHY and other cardiomyopathies.

Diseases caused by abnormal function of the MITOCHONDRIA. They may be caused by mutations, acquired or inherited, in mitochondrial DNA or in nuclear genes that code for mitochondrial components. They may also be the result of acquired mitochondria dysfunction due to adverse effects of drugs, infections, or other environmental causes.
Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death. (from Braunwald's Heart Disease: A Textbook of Cardiovascular Medicine, 7th ed., 2005)
A condition characterized by the thickening of the ventricular ENDOCARDIUM and subendocardium (MYOCARDIUM), seen mostly in children and young adults in the TROPICAL CLIMATE. The fibrous tissue extends from the apex toward and often involves the HEART VALVES causing restrictive blood flow into the respective ventricles (CARDIOMYOPATHY, RESTRICTIVE).
The lower right and left chambers of the heart. The right ventricle pumps venous BLOOD into the LUNGS and the left ventricle pumps oxygenated blood into the systemic arterial circulation.
A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.
Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA.

Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues. The standard approach is transthoracic.
One of the three polypeptide chains that make up the TROPONIN complex. It is a cardiac-specific protein that binds to TROPOMYOSIN. It is released from damaged or injured heart muscle cells (MYOCYTES, CARDIAC). Defects in the gene encoding troponin T result in FAMILIAL HYPERTROPHIC CARDIOMYOPATHY.
The hollow, muscular organ that maintains the circulation of the blood.
The mitochondria of the myocardium.
A type of imaging technique used primarily in the field of cardiology. By coordinating the fast gradient-echo MRI sequence with retrospective ECG-gating, numerous short time frames evenly spaced in the cardiac cycle are produced. These images are laced together in a cinematic display so that wall motion of the ventricles, valve motion, and blood flow patterns in the heart and great vessels can be visualized.
The larger subunits of MYOSINS. The heavy chains have a molecular weight of about 230 kDa and each heavy chain is usually associated with a dissimilar pair of MYOSIN LIGHT CHAINS. The heavy chains possess actin-binding and ATPase activity.
The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment.
The record of descent or ancestry, particularly of a particular condition or trait, indicating individual family members, their relationships, and their status with respect to the trait or condition.
Contractile activity of the MYOCARDIUM.
A condition in which the LEFT VENTRICLE of the heart was functionally impaired. This condition usually leads to HEART FAILURE; MYOCARDIAL INFARCTION; and other cardiovascular complications. Diagnosis is made by measuring the diminished ejection fraction and a depressed level of motility of the left ventricular wall.
Proteins produced from GENES that have acquired MUTATIONS.
The long cylindrical contractile organelles of STRIATED MUSCLE cells composed of ACTIN FILAMENTS; MYOSIN filaments; and other proteins organized in arrays of repeating units called SARCOMERES .

Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY.
A mutation in which a codon is mutated to one directing the incorporation of a different amino acid. This substitution may result in an inactive or unstable product. (From A Dictionary of Genetics, King & Stansfield, 5th ed)
A muscle protein localized in surface membranes which is the product of the Duchenne/Becker muscular dystrophy gene. Individuals with Duchenne muscular dystrophy usually lack dystrophin completely while those with Becker muscular dystrophy have dystrophin of an altered size. It shares features with other cytoskeletal proteins such as SPECTRIN and alpha-actinin but the precise function of dystrophin is not clear. One possible role might be to preserve the integrity and alignment of the plasma membrane to the myofibrils during muscle contraction and relaxation. MW 400 kDa.
Any pathological condition where fibrous connective tissue invades any organ, usually as a consequence of inflammation or other injury.
A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (CORONARY ARTERY DISEASE), to obstruction by a thrombus (CORONARY THROMBOSIS), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (MYOCARDIAL INFARCTION).
Post-systolic relaxation of the HEART, especially the HEART VENTRICLES.
Diabetes complications in which VENTRICULAR REMODELING in the absence of CORONARY ATHEROSCLEROSIS and hypertension results in cardiac dysfunctions, typically LEFT VENTRICULAR DYSFUNCTION. The changes also result in myocardial hypertrophy, myocardial necrosis and fibrosis, and collagen deposition due to impaired glucose tolerance.
The transference of a heart from one human or animal to another.
The hemodynamic and electrophysiological action of the left HEART VENTRICLE. Its measurement is an important aspect of the clinical evaluation of patients with heart disease to determine the effects of the disease on cardiac performance.
A basic element found in nearly all organized tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
Substances used to allow enhanced visualization of tissues.
The geometric and structural changes that the HEART VENTRICLES undergo, usually following MYOCARDIAL INFARCTION. It comprises expansion of the infarct and dilatation of the healthy ventricle segments. While most prevalent in the left ventricle, it can also occur in the right ventricle.
The protein constituents of muscle, the major ones being ACTINS and MYOSINS. More than a dozen accessory proteins exist including TROPONIN; TROPOMYOSIN; and DYSTROPHIN.

Studies which start with the identification of persons with a disease of interest and a control (comparison, referent) group without the disease. The relationship of an attribute to the disease is examined by comparing diseased and non-diseased persons with regard to the frequency or levels of the attribute in each group.
In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
Pathological conditions involving the CARDIOVASCULAR SYSTEM including the HEART; the BLOOD VESSELS; or the PERICARDIUM.
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
A prediction of the probable outcome of a disease based on a individual's condition and the usual course of the disease as seen in similar situations.

The role of oxidative stress in the genesis of heart disease. (1/2902)

Although researchers in radiation and cancer biology have known about the existence of free radicals and their potential role in pathobiology for several decades, cardiac biologists only began to take notice of these noxious species in the 1970s. Exponential growth of free radical research occurred after the discovery of superoxide dismutase in 1969. This antioxidant enzyme is responsible for the dismutation of superoxide radical--a free radical chain initiator. A fine balance between free radicals and a variety of endogenous antioxidants is believed to exist. Any disturbance in this equilibrium in favour of free radicals causes an increase in oxidative stress and initiates subcellular changes leading to cardiomyopathy and heart failure. Our knowledge about the role of free radicals in the pathogenesis of cardiac dysfunction is fast approaching the point where newer therapies employing antioxidants are in sight.  (+info)

Histamine aggravated levothyroxine-induced cardiomyopathy in guinea pigs. (2/2902)

AIM: To study effects of histamine on cardiomyopathy. METHODS: Cardiomyopathy model was developed in guinea pig by i.p. levothyroxine 0.5 mg.kg-1.d-1 for 10 d. Langendroff's hearts were perfused. ECG and contractile force were recorded. Histamine (5 micrograms) was given by intra-aortic injection. Histamine content of coronary venous effluent was determined fluorometrically. RESULTS: Attack of histamine on cardiomyopathy was severer than that in normal hearts. Tachycardia was more prominent; atrioventricular conduction block occurred earlier; decrease in coronary flow was more marked. Uptakes of histamine were 37% in the model and 19% in the normal hearts (P < 0.01). CONCLUSION: Histamine aggravated levothyroxine-cardiomyopathy.  (+info)

Molecular heterogeneity in very-long-chain acyl-CoA dehydrogenase deficiency causing pediatric cardiomyopathy and sudden death. (3/2902)

BACKGROUND: Genetic defects are being increasingly recognized in the etiology of primary cardiomyopathy (CM). Very-long-chain acyl-CoA dehydrogenase (VLCAD) catalyzes the first step in the beta-oxidation spiral of fatty acid metabolism, the crucial pathway for cardiac energy production. METHODS AND RESULTS: We studied 37 patients with CM, nonketotic hypoglycemia and hepatic dysfunction, skeletal myopathy, or sudden death in infancy with hepatic steatosis, features suggestive of fatty acid oxidation disorders. Single-stranded conformational variance was used to screen genomic DNA. DNA sequencing and mutational analysis revealed 21 different mutations on the VLCAD gene in 18 patients. Of the mutations, 80% were associated with CM. Severe CM in infancy was recognized in most patients (67%) at presentation. Hepatic dysfunction was common (33%). RNA blot analysis and VLCAD enzyme assays showed a severe reduction in VLCAD mRNA in patients with frame-shift or splice-site mutations and absent or severe reduction in enzyme activity in all. CONCLUSIONS: Infantile CM is the most common clinical phenotype of VLCAD deficiency. Mutations in the human VLCAD gene are heterogeneous. Although mortality at presentation is high, both the metabolic disorder and cardiomyopathy are reversible.  (+info)

Cardiac involvement in proximal myotonic myopathy. (4/2902)

Proximal myotonic myopathy (PROMM) is a recently described autosomal dominantly inherited disorder resulting in proximal muscles weakness, myotonia, and cataracts. A few patients with cardiac involvement (sinus bradycardia, supraventricular bigeminy, conduction abnormalities) have been reported. The cases of three relatives with PROMM (weakness of neck flexors and proximal extremity muscles, calf hypertrophy, myotonia, cataracts) are reported: a 54 year old man, his 73 year old mother, and 66 year old aunt. All three presented with conduction abnormalities and one had repeated, life threatening, sustained monomorphic ventricular tachycardia. This illustrates that severe cardiac involvement may occur in PROMM.  (+info)

A calcium antagonist protects against doxorubicin-induced impairment of calcium handling in neonatal rat cardiac myocytes. (5/2902)

The effects of doxorubicin (DOX) on intracellular calcium transients and the cardioprotective effects of a calcium antagonist on DOX-induced impairment of calcium handling were examined in neonatal rat cultured cardiac myocytes. Cultured cardiac myocytes isolated from neonatal Wistar-Kyoto rats were treated with DOX for 24 h. Field-stimulated calcium transients in single myocytes were measured in the presence or absence of isoproterenol using fura-2/AM. Calcium transients were also measured after the addition of DOX to myocytes pretreated with a calcium antagonist, benidipine. DOX reduced the amplitude, maximum velocity of increase and decrease of calcium transients and prolonged the time course of calcium transients and impaired the beta-adrenoceptor responsiveness of calcium transients in a concentration-dependent manner. The DOX-induced impairment of calcium transients and beta-adrenoceptor responsiveness was improved by 10(-8) mol/L of benidipine. However, these improvements decreased with increasing concentrations of benidipine. DOX impaired both the mobilization and removal of intracellular calcium ions in contraction-relaxation cycles and the response of calcium transients to beta-adrenoceptor stimulation. Appropriate concentration of benidipine ameliorated DOX-induced impairment of calcium dynamics, suggesting that benidipine, a long-acting calcium antagonist, has potential clinical usefulness on DOX-induced abnormal calcium handling.  (+info)

Evidence of cell-mediated cardiac myocyte injury involved in the heart failure of a patient with progressive systemic sclerosis. (6/2902)

A 54-year-old woman with progressive systemic sclerosis (PSS) was admitted to hospital because of dyspnea and chest pain. Echocardiogram revealed diffuse hypokinesis of the left ventricle (ejection fraction 24%). Methylprednisolone, heparin, and diuretics were administered, without benefit. Anemia, thrombocytopenia, and renal dysfunction rapidly progressed, and she died of heart failure on the 14th hospital day. Immunohistochemical study of the myocardial tissue showed mild to moderate cell infiltration, mainly consisting of natural killer (NK) cells, macrophages, cytotoxic T lymphocytes (CTLs), and T helper cells. Perforin, a cytolytic factor, was expressed in the infiltrating CTLs and NK cells, indicating that these cells were activated killer cells. Furthermore, human leukocyte antigen classes I and II, intercellular adhesion molecule-1, as well as costimulatory molecules B7-1, B7-2, and CD40, all of which are known not to be expressed in cardiac myocytes under normal conditions, were moderately to strongly expressed in cardiac myocytes. There was no detectable level of enterovirus genomes in the polymerase chain reaction products from the myocardial tissue of this patient. These findings strongly suggest that the infiltrating killer cells recognized cardiac myocytes as target cells and directly damaged them by releasing perforin. Enhanced expression of these antigens may have played an important role in the activation and cytotoxicity of the infiltrating killer cells. Absence of enterovirus genomes in the myocardial tissue may suggest that this autoimmune process is primarily induced by PSS.  (+info)

Use of an intravenous contrast agent (Optison) to enhance echocardiography: efficacy and cost implications. Optison Multicenter Study Group. (7/2902)

OBJECTIVE: To compare the overall diagnostic costs associated with non-contrast and contrast echocardiography. STUDY DESIGN: Phase III clinical trial. PATIENTS AND METHODS: In a secondary analysis of data from a phase III clinical trial of the intravenous contrast agent Optison, we compared the costs associated with obtaining a diagnosis in 203 patients who underwent non-contrast and contrast echocardiography. Costs for the initial test and any follow-up tests were derived from adjusted Medicare charges and a transition-1 microcost accounting system. RESULTS: Diagnostic yield from echocardiograms was 87% with the use of Optison (3 mL) and 49% when no contrast agent was used (P < 0.001). Because technically inadequate echocardiograms were more common in the non-contrast group, follow-up testing was recommended for 42% of patients in this group compared with 12% of those who had undergone a contrast-enhanced echocardiogram (P < 0.001). Although use of Optison increased the initial diagnostic cost by $125, overall costs were 17% lower when Optison was used (P < 0.0001). Use of Optison also resulted in a 17% to 70% decrease in confirmatory transesophageal echocardiography, catheterization, and nuclear studies. Optison improved diagnostic accuracy by 2.7-fold in patients with an initial non-diagnostic echocardiogram, resulting in a substantial cost savings of $269 per patient.  (+info)

Transcomplementation between different types of respiration-deficient mitochondria with different pathogenic mutant mitochondrial DNAs. (8/2902)

Two cell lines were used for determination of whether interaction occurred between different types of respiration-deficient mitochondria. One was a respiration-deficient rho- cell line having mutant mitochondrial DNA (mtDNA) with a 5,196-base pair deletion including five tRNA genes (tRNAGly, Arg, Ser(AGY), Leu(CUN), His), DeltamtDNA5196, causing Kearns-Sayre syndrome. The other was a respiration-deficient syn- cell line having mutant mtDNA with an A to G substitution at 4,269 in the tRNAIle gene, mtDNA4269, causing fatal cardiomyopathy. The occurrence of mitochondrial interaction was examined by determining whether cybrids constructed by fusion of enucleated rho- cells with syn- cells became respiration competent by exchanging their tRNAs. No cybrids were isolated in selection medium, where only respiration-competent cells could survive, suggesting that no interaction occurred, or that it occurred so slowly that sufficient recovery of mitochondrial respiratory function was not attained by the time of selection. The latter possibility was confirmed by the observations that heteroplasmic cybrids with both mutant mtDNA4269 and DeltamtDNA5196 isolated without selection showed restored mitochondrial respiration activity. This demonstration of transcomplementation between different respiration-deficient mitochondria will help in understanding the relationship between somatic mutant mtDNAs and the roles of such mutations in aging processes.  (+info)

Speckle tracking echocardiography (STE) has gained importance in the evaluation of adult inherited cardiomyopathies, but its utility in children is not well characterized. We conducted a systematic review to evaluate the role of STE in pediatric inherited cardiomyopathies. PubMed, EMBASE, Web of Science, Scopus, CENTRAL and CINAHL databases were searched up to May 2020, for terms related to inherited cardiomyopathies and STE. Included were dilated cardiomyopathy (DCM), hypertrophic cardiomyopathy (HCM), left ventricular non-compaction (LVNC) and arrhythmogenic cardiomyopathy (ACM). A total of 14 cohorts were identified, of which six were in DCM, four in HCM, three in LVNC and one in ACM. The most commonly reported STE measurements were left ventricular longitudinal strain (Sl), circumferential strain (Sc), radial strain (Sr) and rotation/torsion/twist. Sl, Sc and were abnormal in all DCM and LVNC cohorts, but not in all HCM. Apical rotation and twist/torsion were increased in HCM, and decreased ...
Background: Past data suggest ischemic cardiomyopathy (ICM) is associated with worse prognosis when compared to non-ischemic cardiomyopathy(NICM). With advances in heart failure management, this relationship deserves a fresh look. We hypothesize that all cause mortality from NICM is lower when compared to ICM over five year period.. Methods: We retrospectively studied consecutive heart failure patients with left ventricular ejection fraction(EF) less than 35% admitted to Einstein Medical Center Philadelphia between 01/01/2007 to 12/31/2007. Data pertaining to patient demographics and clinical characteristics were obtained. All cause mortality was obtained at 5 years using hazard ratio to account for time to event.. Results: The final cohort consisted of 360 patients of which 63%(224 of 360) had NICM. Mean age was 61±16 years for NICM and 66±11 yrs for ICM. African Americans constituted 83%(185 of 224) of NICM and 59%(80 of 136) of ICM. The clinical characteristics are as shown in the table. ...
Cardiomyopathy refers to diseases of the heart muscle which cause the heart to become weaker. There are many different causes of cardiomyopathy. This study is looking at patients with cardiomyopathy that is not due to a reduced blood supply to the heart muscle. Reduced blood supply is called ischemic, so this study is looking at patients with non-ischemic cardiomyopathy (NICM). Ejection fraction (EF) is the amount of blood leaving the heart each time it contracts. EF is a measure of the strength, or how well the heart pumps with each beat and it is measured on tests such as echocardiogram (ultrasound) and cardiac magnetic resonance imaging (CMR). Patients newly diagnosed with NICM who have a reduced ejection fraction (EF) of less than or equal to 40% may be eligible for this study. Patients with NICM are at increased risk for hospitalizations due to congestive heart failure, abnormal heart rhythms and are also at an increased risk of sudden cardiac death. An implanted device, called an ...

Cirrhosis is known to cause alterations in the systemic haemodynamic system. Cirrhotic cardiomyopathy designates a cardiac dysfunction that includes impaired cardiac contractility with systolic and diastolic dysfunction, as well as electromechanical abnormalities in the absence of other known causes of cardiac disease. This condition is primarily revealed by inducing physical or pharmacological stress, but echocardiography is excellent at revealing diastolic dysfunction and might also be used to detect systolic dysfunction at rest. Furthermore, measurement of circulating levels of cardiac biomarkers could improve the diagnostic assessm+ent. Cirrhotic cardiomyopathy contributes to various complications in cirrhosis, especially as an important factor in the development of hepatic nephropathy. Additionally, cirrhotic cardiomyopathy seems to be associated with the development of heart failure in relation to invasive procedures such as shunt insertion and liver transplantation. Current ...
Rituximab is an anti-CD20 monoclonal antibody frequently used for the treatment of non-Hodgkins lymphoma, chronic lymphocytic leukemia (CLL), rheumatoid arthritis (RA), and anti-neutrophilic cytoplasmic antibody (ANCA)-associated vasculitis. In addition, rituximab has recently been increasingly used as an off-label treatment in a number of inflammatory and systemic autoimmune diseases. It is advised that rituximab infusion may cause infusion reactions and adverse cardiac effects including arrhythmia and angina, especially in patients with prior history of cardiovascular diseases. However, its detailed cardiotoxicity profile and effects on cardiac function were not well described. We report a 51-year-old man who developed non-ischemic cardiomyopathy after rituximab treatment for membranous nephropathy. The patient experienced reduced cardiac functions within 48 hours after the initial infusion, which remained markedly reduced at 9-month follow-up. As the utility of rituximab expands, physicians must be

PurposeIntegrating genomic sequencing in clinical care requires standardization of variant interpretation practices. The Clinical Genome Resource has established expert panels to adapt the American College of Medical Genetics and Genomics/Association for Molecular Pathology classification framework for specific genes and diseases. The Cardiomyopathy Expert Panel selected MYH7, a key contributor to inherited cardiomyopathies, as a pilot gene to develop a broadly applicable approach.MethodsExpert revisions were tested with 60 variants using a structured double review by pairs of clinical and diagnostic laboratory experts. Final consensus rules were established via iterative discussions.ResultsAdjustments represented disease-/gene-informed specifications (12) or strength adjustments of existing rules (5). Nine rules were deemed not applicable. Key specifications included quantitative frameworks for minor allele frequency thresholds, the use of segregation data, and a semiquantitative approach to counting
Genetic test that analyzes 106 genes that cause inherited cardiomyopathies, inherited arrhythmias, and other inherited cardiovascular conditions. Testing uses Sanger and next generation sequencing.
Diabetes is associated with myocardial lipid accumulation and an increased risk of heart failure. Although cardiac myocyte lipid overload is thought to contribute to the pathogenesis of cardiomyopathy in the setting of diabetes, the mechanism(s) through which this occurs is not well understood. Increasingly, inflammation has been recognized as a key pathogenic feature of lipid excess and diabetes. In this study, we sought to investigate the role of inflammatory activation in the pathogenesis of lipotoxic cardiomyopathy using the α-myosin heavy chain promoter-driven long-chain acylCoA synthetase 1 (MHC-ACS) transgenic mouse model. We found that several inflammatory cytokines were upregulated in the myocardium of MHC-ACS mice before the onset of cardiac dysfunction, and this was accompanied by macrophage infiltration. Depletion of macrophages with liposomal clodrolip reduced the cardiac inflammatory response and improved cardiac function. Thus, in this model of lipotoxic cardiac injury, early ...
This study showed that 1 the improvement of left ventricular systolic function and remodeling was reduced in ischemic cardiomyopathy patients compared with non-ischemic cardiomyopathy patients; 2 compared with non-ischemic cardiomyopathy patients, ischemic cardiomyopathy patients exhibited more severe diastolic dysfunction; and 3 severe diastolic dysfunction (restrictive filling) was an independent factor influencing the CRT response.. Many randomized controlled trials and observational studies 3,4,13-15 have shown that CRT results in less improvement in LV systolic function and remodeling in ICM patients than in NICM patients. This study showed that the ICM group had lower CRT response rates six months after implantation; improvements in LVEF and LVOT-VTI, which reflect LV function, and improvements in LVESV, which reflect remodeling, were smaller in the ICM group than in the NICM group. These results are not surprising. Several groups reported similar findings as long as a decade ago 16-18. ...

Cardiomyopathies are diseases of heart muscle, a significant percentage of which are genetic in origin. Cardiomyopathies can be classified as dilated, hypertrophic, restrictive, arrhythmogenic right ventricular or left ventricular non-compaction, although mixed morphologies are possible. A subset of neuromuscular disorders, notably Duchenne and Becker muscular dystrophies, are also characterized by cardiomyopathy aside from skeletal myopathy. The global burden of cardiomyopathies is certainly high, necessitating further research and novel therapies. Genome editing tools, which include zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs) and clustered regularly interspaced short palindromic repeats (CRISPR) systems have emerged as increasingly important technologies in studying this group of cardiovascular disorders. In this review, we discuss the applications of genome editing in the understanding and treatment of cardiomyopathy. We also describe recent advances in
Background: Progressive apoptosis following the primary injury has been implicated in the progression to end-stage heart failure. Survivin, a member of the inhibitor of apoptosis protein, is one of the most potent suppressor of apoptosis. We hypothesized that preventing apoptosis by survivin gene therapy may prevent deterioration in left ventricular (LV) systolic dysfunction in a doxorubicin-induced cardiomyopathy model in rats.. Methods and Results: A reproducible model of doxorubicin (dox)-induced cardiomyopathy was established in male Fisher rats by 6 equal doses (2.5 mg/kg bw) of i.p. injection every other day for 2 weeks. Echocardiographic assessment was performed at week 0, 3, and 6. A subset of animals (DOX+SURV, n=8) was treated with the survivin gene using the ultrasound targeted microbubble destruction (UTMD) technique at week 3. Control animals (DOX, n=12) did not receive any treatment at week 3. At week 0 (pre-dox), LV% fractional shortening (FS) was comparable in DOX+SURV and DOX ...
Its arrhythmia week on The Rounds Table! Should heart failure patients give up a caffeine jolt in the morning? How can we better identify appropriate patients for ICDs? Paxton Bach, fellow in General Internal Medicine at UBC, joins Kieran to discuss two exciting studies:. Studies that inform practice toward the best medical treatments are of utmost importance. But, arguably, studies that inform day to day lifestyle choice are those that provide real meaning to patients. For example, does a patient with a heart condition need to give up coffee? Kieran and Paxton discuss a study which examines whether, in patients with decreased ejection fraction, caffeine increases cardiac arrhythmias.. Next, Kieran takes listeners through the DANISH trial. The benefit of an implantable cardioverter-defibrillator (ICD) in patients with symptomatic systolic heart failure caused by ischemic heart disease has been well documented. However, before the DANISH trial, the evidence for implantation of an ICD for primary ...
Get natural cures for Doxorubicin-induced cardiomyopathy that can make a difference in your life or the life of someone you love with alternative treatments.
When implantable cardioverter defibrillators (ICDs) were first approved by the FDA in 1985, the recipient needed to have survived not one, but two cardiac arrests. The initial population receiving ICDs was obviously very small.
Imaging plays a crucial role in the diagnosis, management, and prognosis assessment of patients with nonischemic cardiomyopathies. Over the past decade, the role of cardiovascular magnetic resonance imaging in clinical practice has been rapidly expanding. The techniques unsurpassed accuracy in defining cardiac morphology and function and ability to provide tissue characterization make it particularly well suited for the study of patients with nonischemic cardiomyopathies. In this review article, we provide an overview of the main cardiovascular magnetic resonance features of nonischemic cardiomyopathies, highlighting the diagnostic and prognostic utility of the technique in this heterogenous group of diseases.
Increased circulating levels of free fatty acid (FA) in obesity and diabetes lead to the accumulation of FA in non-adipose tissue such as myocardium and this is known to be a major contributor to cardiomyopathy. In this present study, we investigated the role of APPL1 (Adaptor protein containing PH domain, PTB domain and Leucine zipper motif-1), an important regulator of insulin signaling, in a model of high fat diet (HFD) induced cardiomyopathy. We fed APPL1 transgenic (Tg) or wild type (wt) mice a high fat (60% kcal) or normal chow diet. After 16 weeks, in wt mice HFD induced hyperinsulinemia and hyperlipidemia, as well as cardiac dysfunction determined by echocardiography system (Vevo 2100). Furthermore, HFD induced cardiac insulin resistance and acetyl CoA carboxylase (ACC) phosphorylation. Lipid analysis using LC/MS/MS showed HFD significantly increased intracellular level of distinct ceramide and diacylglycerol (DAG) species in heart tissue. Interestingly, HFD fed APPL1 Tg mice showed a ...
Although clinical studies indicate that patients with idiopathic dilated congestive cardiomyopathy who develop electrocardiographic or angiographic signs of left ventricular (LV) hypertrophy may survive longer, there is little morphologic evidence for such anatomic favorable of unfavorable prognostic groups. We studied 30 autopsied patients who died of dilated cardiomyopathy; of these, 15 died within 1 year of the first symptom of their disease (short-term survivors) and 15 patients died 1-14 years after initial symptoms (long-term survivors). There were no significant differences in sex, race, clinical presentation or cause of death between the groups, but there were significant morphologic differences. In the short-term survivors, average heart weight was 540 g and LV wall thickness was 1.0 cm, whereas in the long-term survivors, the average heart weight was 759 g and LV wall thickness was 1.3 cm (p less than 0.001). LV cavity dilatation as measured by maximal transverse diameter from the ...
Genetic testing for potentially heritable cardiomyopathies has advanced from basic scientific discovery to clinical application. Nowadays, genetic diagnostic tests for cardiomyopathies are clinically available. As a consequence is fundamental the understanding of the clinical utility, in terms of diagnosis and prognosis, of genetic test results. In addition, the genetic counselling, regarding risks, benefits and options, is recommended for all patients and their relatives. However the relation between genotype and phenotype remains often unclear, and there is frequently a variance of uncertain significance. Consequently, the genetic test should always be approached as one component of a comprehensive cardio-genetic evaluation. This review aims to explore when genetic tests are indicated in patients with dilated and hypertrophic cardiomyopathy ...

Cardiomyopathies are diseases characterised by structural and functional abnormalities of the myocardium. There are various types and subtypes, some of which have a strong genetic component. The understanding of cardiomyopathies has been enhanced by advances in the fields of medicine and genetics.
PMCMP : Sudden cardiac death (SCD) is estimated to occur at an incidence of between 50 to 100 per 100,000 individuals in North America and Europe each year, claiming between 250,000 and 450,000 lives in the United States annually. In younger individuals (ages 15-35), the incidence of SCD is between 1 to 2 per 100,000 young individuals. Sudden cardiac death, particularly in young individuals, may suggest an inherited form of heart disease. In some cases of sudden cardiac death, autopsy may identify a structural abnormality such as a form of cardiomyopathy. Postmortem diagnosis of a hereditary cardiomyopathy may assist in confirmation of the cause and manner of death, as well as risk assessment in living family members.   The cardiomyopathies are a group of disorders characterized by disease of the heart muscle. Cardiomyopathies are often caused by inherited, genetic, factors. When the identified structural or functional abnormality observed in a patient cannot be explained by acquired causes,
F49 Molecular Cloning and Sequencing of the HRC Gene from Mouse Heart Reveals a Highly Unstable GAG Repeat. Shundi Shi, Steven R. Brunnert. Columbia University, Institute of Comparative Medicine 630 W. 168th Street, Mail Box 17, New York, NY 10032. Histidine-rich calcium binding protein (HRC) is a luminal sarcoplasmic reticulum protein that has been mapped to human Chromosome 19 and mouse Chromosome 7 and considered a candidate gene of several genetic diseases in humans and mice. We derived a 2407-bp clone encoding for a 738 AA protein by PCR from C57BL/6J mouse heart and found a highly unstable GAG repeat in the middle of the coding region. The instability of the GAG repeat could be detected within individual C57BL/6J and DBA/2J mice in both genomic DNA and cDNA, and no polymorphism was found between two mouse HRC cDNAs except the unstable GAG repeats. At normal physiologic conditions, no GAG expansion was found in the unstable GAG repeat region in the dystrophic cardiac calcinosis (DCC) ...
Late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) imaging is a tool for noninvasive evaluation of myocardial viability that has the advantage over other imaging techniques of being able to directly visualize nonviable myocardium with excellent contrast and spatial resolution. In addition to use in patients with coronary artery disease, this imaging technique has diagnostic value in the setting of nonischemic cardiomyopathy.. Variable patterns of LGE have been described in a wide variety of cardiomyopathies. These patterns are usually quite distinct from LGE seen after myocardial infarction and may even be disease specific. Mid-myocardial enhancement is found in hypertrophic cardiomyopathy at the site of collagen deposition (1), and small patches of predominantly subepicardial enhancement may be seen with acute myocarditis (2). Hence, CMR is a tool for differentiation between ischemic and nonischemic cardiomyopathy and for identification of disease-specific patterns of ...

Objective: Diabetic cardiomyopathy is associated with increased mortality in patients with diabetes mellitus. The underlying pathology of this disease is still under discussion. We studied the role of the kinin B1 receptor on the development of experimental diabetic cardiomyopathy.. Research Design and Methods: We utilized B1 receptor knockout mice and investiged cardiac inflammation, fibrosis and oxidative stress after induction of streptozotocin (STZ)-induced diabetes mellitus. Furthermore, the left ventricular function was measured by pressure-volume loops after 8 weeks of diabetes mellitus.. Results: B1 receptor knockout mice showed an attenuation of diabetic cardiomyopathy with improved systolic and diastolic function in comparison with diabetic control mice. This was associated with a decreased activation state of the MAP kinase p38, less oxidative stress as well as normalized cardiac inflammation, shown by fewer invading cells and, no increase in matrix metalloproteinase-9 as well as the ...
Doxorubicin (DOX) is an effective antineoplastic agent used for the treatment of a variety of cancers. Unfortunately, its use is limited as this drug induces cardiotoxicity and heart failure as a side effect. There is no report that describes whether
Background: Impairment of systolic function and late gadolinium enhancement (LGE) are well-known negative prognostic markers in non-ischemic cardiomyopathies (NICMPs). There is limited knowledge of the geometrical rearrangements of the ventricle volumes over size of the left atrium and their connections with systolic dysfunction and existence of LGE. Material/Methods: Consecutive cases of NICMPs with impaired systolic function and controls were included from a computerized database of cardiac magnetic resonance exams for a 2.5-year period. Ratios made from volumetric parameters over left atrial area (LAA) area were calculated. Results: Our study included 205 cases referred to cardiac magnetic resonance (CMR); age was 48.7±17.0 years (range 15.2-80.4), male-to-female ratio 137 (66.8%): 68 (33.2%), (both p,0.05). LGE was significantly correlated with impairment of systolic function (Rho CC=0.395; p,0.001). For detection of systolic impairment, a critical value of end-systolic-volume (ESV)/LAA of ...
Nitric oxide is produced in cardiac microvascular endothelial cells and cardiomyocytes from either constitutive or inducible nitric oxide synthase (NOS), which catalyses the conversion of L-arginine to L-citrulline. Cardiomyocytes principally express endothelial NOS, localized near invaginations of the plasmalemma termed caveolae, and neuronal NOS, localized on the sarcoplasmic reticulum (61). A third isoform, the inducible nitric oxide synthase (iNOS), may be expressed upon stimulation with inflammatory mediators. While NO synthesized by neuronal NOS and endothelial NOS has cardioprotective effects through improvement of perfusion and inhibition of apoptosis, NO derived from iNOS has a cardiotoxic effect through the suppression of muscle wall contractility and induction of apoptosis (62). Nitric oxide is released in a pulsatile manner from the beating heart. Changes in ventricular filling induce parallel increases or decreases in cardiac NO synthesis, which, in turn, modulate the function of ...
Despite the striking advances in medical and surgical therapy, the morbidity, mortality, and economic burden of heart failure (HF) remain unacceptably high. There is increasing evidence that the risk and course of HF depend on genetic predisposition; however, the genetic contribution to HF is heterogeneous and complex. At one end of the spectrum are the familial monogenic HF syndromes in which causative mutations are rare but highly penetrant. At the other, HF susceptibility and course may be influenced by more common, less penetrant genetic variants. As detailed in this review, efforts to unravel the basis of the familial cardiomyopathies at the mendelian end of the spectrum already have begun to deliver on the promise of informative mechanisms, novel gene-based diagnostics, and therapies for distinct subtypes of HF. However, continued progress requires the differentiation of pathogenic mutations, disease modifiers, and rare, benign variants in the deluge of data emerging from increasingly accessible

Cardiac hypertrophy is viewed as a compensatory response to increased load common to diverse clinical settings such as hypertension, valvular disease, and inherited cardiomyopathies (Sadoshima and Izumo, 1997; MacLellan and Schneider, 2000). Myocytes respond to pressure overload with the addition of sarcomeres, resulting in an increase in ventricular wall thickness, which itself is an independent risk factor for cardiovascular mortality (Mathew et al., 2001; Verdecchia et al., 2001). Hence, blunting hypertrophic growth might be beneficial to cardiac function, and previous studies of genetically engineered mice disrupting certain hypertrophic pathways confirm this prediction (Esposito et al., 2002; Sano and Schneider, 2002). However, we still do not know which pathways hold greatest potential for therapeutic benefit. Although the signaling pathways that activate hypertrophy have been described in detail (McKinsey and Olson, 1999; Molkentin and Dorn, 2001), still very little is known of mechanisms ...

Clozapine is a dibenzodiazepine antipsychotic used for treatment-resistant schizophrenia. Its association with several side effects such as agranulocytosis, seizure, and insulin resistance is well known. Cardiac side effects such as myocarditis and cardiomyopathy are less common and have been seldom reported. Here we report an unusual case of clozapine-induced nonischemic dilated cardiomyopathy. A 50-year-old female with treatment-resistant schizophrenia on clozapine presented with gradually worsening shortness of breath, productive cough, and pleuritic chest pain. She was found to have non-ischemic dilated cardiomyopathy due to clozapine use as no other causative factor was found. Clozapine was gradually tapered and then discontinued. Repeat echocardiogram in three months revealed improvement in ejection fraction. This case is unique as it outlines clozapine as a rare cause of nonischemic cardiomyopathy, as discontinuation of the drug showed improvement in symptoms and heart function.
OBJECTIVES. Recently the plication of the left ventricular free wall (PLVFW) was described in healthy dogs, reducing the left ventricular cavity. Based on La Places law this reduction could decrease the tension on the left ventricular wall and improve the ventricular contractility. The goal of this study was to evaluate the safety and efficacy of this technique in dogs with doxorubicin-induced cardiomyopathy and normal ones in a period of six months.. MATERIALS. Five normal mongrel dogs (control group) and three dogs with cardiomyopathy induced by doxorubicin were submitted to PLVFW. After induction with propofol (10 mg/kg) and administration of sevoflurane (3,5 V%)in a oxygen mixture, in a semi-closed circuit system, left thoracotomy on the 6th space, pericardiotomy and PLVPW were performed. The dogs were evaluated 1 day before and 1,2,7,15,21,30,60,90,120,150 and 180 days after the surgery by physical examination, measurement of arterial blood pressure, electrocardiography(ECG), ...
ABSTRACT: Takotsubo or stress cardiomyopathy is a non ischemic disease affecting the myocardium, which presents with typical features of myocardial ischemia. Although the presentation with acute central chest pain and shortness of breath mimics acute myocardial ischemia, there is an absence of actual disruption of cardiac blood supply via the coronaries due to acute plaque rupture or vascular spasm. The underlying pathophysiology of this clinical entity remains largely unclear, but a definite association with physical or emotional stress has been well established, hence the term stress cardiomyopathy. The list of potential triggers continues to grow as the disorder is increasingly detected by clinicians and cardiologists, with better clinical insight and improved availability of cardiac investigations. We report a patient with Takotsubo cardiomyopathy associated with severe hyponatremia ...
Isolated left ventricular non-compaction is the result of incomplete myocardial morphogenesis, leading to persistence of the embryonic myocardium. The condition is recognised by an excessively prominent trabecular meshwork and deep intertrabecular recesses of the left ventricle. These intertrabecular recesses are prone to thrombus formation, with resultant embolic sequelae. We describe a case of cerebral thrombo-embolism in a young woman due to isolated left ventricular non-compaction.
Heart failure, irrespective of its etiology may be viewed as a progressive disorder initiated by a different events and sustained by a multifaceted pathophysiological mechanisms. Regardless of the nature of the initiating events and optimized therapy used, loss of functioning cardiac myocytes developed and the disease progressed. One potential explanation for such progression is that not all pathological mechanisms underlying the disease are antagonized enough by currently used therapeutic strategy. Accordingly, impaired myocardial perfusion secondary to microvascular dysfunction has been postulated to play a major role in the progression of heart failure despite standard therapy for heart failure (1). It has been hypothesized that diffuse subendocardial ischemia due to altered coronary physiology may contribute to the global cardiac dysfunction seen in heart failure patients (2). Accordingly, coronary endothelial dysfunction at the microvascular and epicardial level in patients with acute-onset ...
Left ventricular noncompaction (LVNC) is a cardiomyopathy associated with sporadic or familial disease, the latter having an autosomal dominant mode of transmission. The clinical features associated with LVNC vary from asymptomatic to symptomatic patients, with the potential for heart failure, supraventricular and ventricular arrhythmias, thromboembolic events, and sudden cardiac death. Echocardiography is the diagnostic modality of choice, revealing the pathognomonic features of a thick, bilayered myocardium; prominent ventricular trabeculations; and deep intertrabecular recesses. Widespread use and advances in the technology of echocardiography and cardiac magnetic resonance imaging are increasing awareness of LVNC, and cardiac magnetic resonance imaging is improving the ability to stage the severity of the disease and potential for adverse clinical consequences. Study of LVNC through research in embryology, imaging, and genetics has allowed enormous strides in the understanding of this heterogeneous
Sudden cardiac death (SCD) describes a natural and unexpected death from cardiac causes occurring within a short period of time (generally within 1 h of symptom onset) in the absence of any other potentially lethal condition. Most SCD-related diseases have a genetic basis; in particular congenital cardiac channelopathies and cardiomyopathies have been described as leading causes of SCD. Congenital cardiac channelopathies are primary electric disorders caused by mutations affecting genes encoding cardiac ion channels or associated proteins, whereas cardiomyopathies are related to mutations in genes encoding several categories of proteins, including those of sarcomeres, desmosomes, the cytoskeleton, and the nuclear envelope. The purpose of this review is to provide a general overview of the main genetic variants that have been linked to the major congenital cardiac channelopathies and cardiomyopathies. Functional alterations of the related proteins are also described.
We attempted to alter the inherited myocardial damage and loss of contractility of the cardiomyopathic Syrian hamster (strain U-MX7-1) by giving cardiac drugs that altered intracellular calcium and myocardial workload. Thirty-seven 21-day-old cardiomyopathic and thirty-seven 21-day-old normal hamsters were divided into five groups each: verapamil-, propranolol-, digoxin-, hydralazine-, and saline-injected. On their 90th day of life, the hamsters were killed. Of the five cardiomyopathic groups, only verapamil reduced myocardial damage. When both control and cardiomyopathic hamsters were treated with saline, digoxin, or propranolol, the cardiomyopathic hamsters had significantly less contractile force, maximal rate of force development, and maximum velocity of unloaded shortening. When both groups were treated with verapamil or hydralazine, there were no significant group differences in the indices of contractility. However, when saline-treated cardiomyopathic hamsters were compared with ...
We describe a newborn infant with del(1)(q) syndrome, presenting with rare congenital cardiomyopathy and left ventricular noncompaction myocardium (LVNC), as well as typical clinical features such as facial dysmorphism and psychomotor retardation. Although conventional chromosome banding at 850 bands per haploid set indicated a karyotype of 46,XX,add(1)(q42.3), FISH analysis confirmed that the deleted portion was limited to within q43, and q44 was preserved. Therefore, the chromosome constitution is 46,XX,del(1)(q43q43), which has not previously been reported in the literature. Screening for the mutations in the candidate genes for LVNC, i.e. G4.5, CSX, Dystrobrevin, FKBP12, and Desmin, produced negative results. Interestingly, the deleted portion includes the locus for the cardiac ryanodine receptor type 2 gene (RyR2), that selectively binds to the FKBP12 homolog, FKBP12.6. The relationship between this rare myocardial abnormality and deletion of q43 is currently unknown and awaits further accumulation
Ultrasonography is commonly used to diagnose left ventricular noncompaction (LVNC). A ratio of noncompacted to compacted myocardium (NC/C ratio) | |2 is often used to diagnose LVNC. However, a large proportion of patients with noncompact myocardium have NC/C | 2, and the prognosis of these patients have not been studied. We included children diagnosed with LVNC between 0 and 15 years of age from January 2007 to December 2018. LVNC was diagnosed based on Stöllberger standard when over three trabeculae were found to be associated with the interventricular recesses. A maximal end systolic ratio of noncompacted to compacted layers was NC/C ratio. Outcomes for LVNC subjects with NC/C | 2 and NC/C | 2 were compared using Kaplan-Meier methods. There were 124 newly diagnosed LVNC cases, classified as isolated (i-LVNC, n = 47) or non-isolated (ni-LVNC, n = 77) LVNC and NC/C | 2 (n = 43) or | 2 (n = 81). The median (interquartile range) follow-up duration was 12 (3-30) months for all patients and 16 (6-36)
According to the WHO definition cardiomyopathies are classified by the dominant pathophysiology or, if possible, by aetiological or pathogenetic factors.2 Although the cause of IVNC is not fully elucidated, the disease is thought to be a morphogenetic abnormality involving an arrest of compaction of the loose myocardial meshwork during fetal ontogenesis. This implies that IVNC should be present at birth in all patients, a notion supported by two previous reports.6 19 Since IVNC has so far lacked a pathophysiological characterisation, this congenital anomaly has been unspecifically assigned to a heterogeneous group of unclassified cardiomyopathies. This may contribute to the fact that the diagnosis of IVNC is mostly missed, as was true for almost 90% of the patients with IVNC in a series recently reported by Ichida and colleagues.6 Prominent left ventricular trabeculation can be found in healthy hearts as well as in hypertrophic cardiomyopathy and in LVH secondary to dilated, valvar, or ...

To determine the prognostic role of big endothelin-1 (ET-1) in left ventricular non-compaction cardiomyopathy (LVNC).We prospectively enrolled patients whose LVNC was diagnosed by cardiac MRI and who had big ET-1 data available. Primary end point was a composite of all-cause mortality, heart transplantation, sustained ventricular tachycardia/fibrillation and implanted cardioverter defibrillator discharge. Secondary end point was cardiac death or heart transplantation.Altogether, 203 patients (median age 44 years; 70.9% male) were divided into high-level (≥0.42 pmol/L) and low-level (,0.42 pmol/L) big ET-1 groups according to the median value of plasma big ET-1 levels. Ln big ET-1 was positively associated with Ln N-terminal pro-brain natriuretic peptide, left ventricular diameter, but negatively related to age and Ln left ventricular ejection fraction. Median follow-up was 1.9 years (IQR 0.9-3.1 years). Kaplan-Meier analysis showed that, compared with patients with low levels of big ET-1, ...

Noncompaction cardiomyopathy (NCC) is a congenital heart disease that causes ventricular dysfunction and high mortality rate in children. The mechanisms responsible for NCC are still unknown. The steroid receptor coactivator-1 (SRC-1) and SRC-3 are transcriptional coactivators for nuclear hormone receptors and certain other transcription factors that regulate many genes in development and organ function. However, the roles of SRC-1/3 in heart morphogenesis, function and NCC occurrence are unknown. This study aims to examine the spatial and temporal expression patterns of SRC-1/3 in the heart and investigate the specific roles of SRC-1/3 in heart development, function and NCC occurrence. Immunochemical analysis detected SRC-1/3 expressions in the proliferating cardiomyocytes of mouse heart at prenatal and neonatal stages, while these expressions disappeared within two weeks after birth.

Takotsubo/stress cardiomyopathy (TC) or apical ballooning syndrome is an increasingly recognised entity around the world. It is an acute reversible cardiac syndrome that has a striking female predominance, with approximately 90 % of cases occurring in women, the vast majority of whom are post-menopausal. Chest pain and dysponea are the most common presenting symptoms. The symptoms and signs are similar to those in other acute cardiac conditions characterised by acute myocardial ischemia or heart failure. A characteristic feature of the syndrome is its relationship to emotional or physical stressful triggers. The process of diagnosing TC is, to a large extent, one of exclusion of other conditions that it mimics. The Mayo Clinic diagnostic criteria are the most widely used. Since acute coronary syndrome is often suspected before the diagnosis of TC is made, initial treatment is often similar to that for an acute myocardial infarction. However, after the diagnosis of TC is confirmed, treatment is ...
First, it is important to understand what stress is. Stress refers to the bodys response to things it perceives as abnormal. These abnormalities can be physical such as high body temperature, dehydration, or low blood sugar, or can be emotional, such as receiving news that a loved one has passed away. When these abnormalities occur, the body produces various hormones and proteins such as adrenaline and noradrenaline which are meant to help cope with the stress. For example, if a person is suddenly threatened and fears physical harm, the body produces large amounts of adrenaline to help that person either defend himself/herself or run faster to escape the danger. Adrenaline is also produced from physical stressors to the body such as stroke, seizure, difficulty breathing (such as a flare of asthma or emphysema), or significant bleeding. With stress cardiomyopathy, the heart muscle is overwhelmed by a massive amount of adrenaline that is suddenly produced in response to stress.. The precise ...

Cardiac hypertrophy is definitely a key structural feature of diabetic cardiomyopathy in the late stage of diabetes. pathways were enriched in the diabetic heart. Of these, MAPK signaling pathway was prominent. and studies have confirmed that three major subgroups of MAPK including ERK1/2, JNK, and p38, are specifically upregulated in cardiomyocyte hypertrophy during hyperglycemia. To further explore the potential involvement of miRNAs in the rules of glucose-induced cardiomyocyte hypertrophy, neonatal rat cardiomyocytes were exposed to high glucose and transfected with miR-373 mimic. Overexpression of miR-373 decreased the cell size, and also reduced the level of its target gene MEF2C, and miR-373 manifestation was controlled by p38. Our data focus on an important part of miRNAs in diabetic cardiomyopathy, and implicate the reliability of bioinformatics analysis in dropping light within the mechanisms underlying diabetic cardiomyopathy. MicroRNAs (miRNAs) are a class of endogenous, small, ...

Jack-just a heads-up on chronic hydroxychloroquine use. While serving as in locums hospital attending at Westchester Medical Center recently I became aware of 3-4 cases of biopsy proven cardiomyopathy due to HCQ. Unlike the rare case of acute cardiac toxicity associated with short-term use of HCQ, these were all long-term treatments for RA and the patients presented with cardiac decompensation misattributed to ischemic and/or non-ischemic cardiomyopathy. Also note that HCQ toxicity is now more apparent than in the past.(In early toxicity there are no visible signs, but field, OCT and mfERG changes can be detected). Have a good meeting in Hawaii- ...
Dilated cardiomyopathy, a disease of unknown etiology and pathogenesis, is associated with heart failure and compensatory hypertrophy. Although cell and animal models suggest a role for altered gene expression in the transition to heart failure, there is a paucity of data derived from the study of human heart tissue. In this study, we used DNA microarray profiling to investigate changes in the expression of genes involved in apoptosis that occur in human idiopathic dilated cardiomyopathic hearts that had progressed to heart failure.

Sudden cardiac death (SCD) is responsible for 300,000-450,000 deaths per year in the United States. While it is well known that patients with both ischemic and non-ischemic cardiomyopathy (ICM, NICM) are at increased risk for SCD, there is little beyond ejection fraction which has proven useful as a noninvasive predictor to risk stratify these patients.. Myocardial scar has been validated as an arrhythmic substrate in ischemic populations; the majority of successful ablations for lethal ventricular arrhythmias are performed on tissues in peri-infarct regions. Scar provides an anatomic electrical boundary where peri-infarct zones may lead to areas of slow conduction due to the disruption of inter-myocyte electrical conduction.. Myocardial scar is a less organized collagen deposition which disrupts the typical cardiac extracellular matrix. The collagen matrix provides mechanical support to the myocardium dictating ventricular shape, size and stiffness. While typically relatively dormant, the ...
Non-compaction of the left ventricular myocardium (LVNC) has gained increasing recognition during the last 25 years. There is a morphological trait of the myocardial structure with a spectrum from normal variants to the pathological phenotype of LVNC, which reflects the embryogenic structure of the human heart due to an arrest in the compaction process during the first trimester. It must be cautioned not to overdiagnose LVNC: the morphological spectrum of trabeculations, from normal variants to pathological trabeculations with the morphological feature of LVNC must be carefully considered. The classical triad of complications are heart failure, arrhythmias, including sudden cardiac death, and systemic embolic events. Non-compaction of the left ventricular myocardium can occur in isolation or in association with congenital heart defects (CHDs), genetic syndromes, and neuromuscular disorders among others. The clinical spectrum is wide and the outcome is more favourable than in previously described ...
The term cardiomyopathy is used to indicate myocardial dysfunction in the absence of an obstructive lesion or sustained hypertension. Cardiomyopathy can occur either in isolation or as a manifestation of a multisystem disease. Neonates who have an unrecognized cardiomyopathy may come to medical attention with a life-threatening decompensation associated with an otherwise minor illness, such as a viral upper respiratory infection. Alternatively, evidence of cardiomyopathy may be noted on an echocardiogram performed for evaluation of an unrelated problem. Other conditions cause ventricular dysfunction but may not have a long-term impact on cardiac muscle function, such as myocarditis or anomalous origin of the left coronary artery from the pulmonary artery, and will be discussed at the end of the chapter. ...
The application of molecular genetics in cardiology is currently producing important results in the study of the pathogenetic mechanisms underlying cardiomyopathies. Recent clinical surveys have indicated that genetic factors play a major pathogenetic role in idiopathic dilated cardiomyopathy (IDC). Familial IDC is frequent (20-30\%) and is probably a heterogeneous entity, as suggested by the clinical variability and the different pattern of inheritance in the affected families. Molecular genetic studies have demonstrated the existence of heterogeneity also at the genetic level. In a series of families with X-linked IDC, the disease gene has been identified as the dystrophin gene. In familial right ventricular cardiomyopathy (or right ventricular dysplasia), a new nosological entity characterized by isolated right ventricular involvement that can mimic IDC, the disease gene has been localized in the long arm of chromosome 14. In families with matrilineal transmission, the cardiomyopathy could be ...

Japanese scientists first identified Takotsubo Syndrome in 1990. While the causes of the condition are not yet fully understood, physicians believe a persons reaction to unexpected stressful events can cause a release of stress hormones that temporarily reduce the hearts ability to pump - causing it to contract less efficiently or irregularly.. The association between stress cardiomyopathy and increasing levels of stress and anxiety has long been established, the reports authors wrote. The psychological, social, and economic distress accompanying the pandemic, rather than direct viral involvement and sequelae of the infection, are more likely factors associated with the increase in stress cardiomyopathy cases. This was further supported by negative COVID-19 testing results in all patients diagnosed with stress cardiomyopathy in the study group.. This said, the researchers also noted some limitations to their study, including that their patient sample solely represented the population of ...

In all these diseases, imaging techniques play a central role. Advan …
Cellular hypertrophy is a fundamental response of the stressed heart. Many of the pathways associated with cell division are known to be activated in this hypertrophic response, leading to the hypothesis that cardiomyocyte hypertrophy might be the result of a fundamental block in karyokinesis and cytokinesis, by which the adult cardiomyocyte is unable to disassemble sarcomeres, uncouple from neighboring cells and divide (Ahuja et al., 2007). Nuclear division and polyploidy are observed in the latest stages of human heart failure and reverse with ventricular unloading, but cellular dynamics earlier in the pathophysiological cascade have not yet been explored (Rivello et al., 2001). In the zebrafish model that we generated, we were able to explore the effects of disrupted sarcomere gene function during cardiogenesis. We found that when the embryonic heart is exposed to a hypertrophic stimulus, in contrast to the response in the adult mammalian heart, a hyperplastic response occurs. Whereas ...
