Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.

Clinical profile and outcome of idiopathic restrictive cardiomyopathy. (1/98)

BACKGROUND: Idiopathic restrictive cardiomyopathy is a poorly recognized entity of unknown cause characterized by nondilated, nonhypertrophied ventricles with diastolic dysfunction resulting in dilated atria and variable systolic function. METHODS AND RESULTS: Between 1979 and 1996, 94 patients (61% women) 10 to 90 years old (mean, 64 years) met strict morphological echocardiographic criteria for idiopathic restrictive cardiomyopathy, mainly dilated atria with nonhypertrophied, nondilated ventricles. None had known infiltrative disease, hypertension of >5 years' duration, or cardiac or systemic conditions associated with restrictive filling. Nineteen percent were in NYHA class I, 53% in class II, and 28% in class III or IV. Atrial fibrillation was noted in 74% of patients and systolic dysfunction in 16%. Follow-up (mean, 68 months) was complete for 93 patients (99%). At follow-up, 47 patients (50%) had died, 32 (68%) of cardiovascular causes. Four had heart transplantation. The death rate compared with actuarial statistics was significantly higher than expected (P<0.0001). Kaplan-Meier 5-year survival was 64%, compared with expected survival of 85%. Multivariate analysis using proportional hazards showed that the risk of death approximately doubles with male sex (hazard ratio [HR] = 2.1), left atrial dimension >60 mm (HR = 2.3), age >70 years (HR = 2.0), and each increment of NYHA class (HR = 2.0). CONCLUSIONS: Idiopathic restrictive cardiomyopathy or nondilated, nonhypertrophic ventricles with marked biatrial dilatation, as defined morphologically by echocardiography, affects predominantly elderly patients but can occur in any age group. Patients present with systemic and pulmonary venous congestion and atrial fibrillation and have a poor prognosis, particularly men >70 years old with higher NYHA class and left atrial dimension >60 mm.  (+info)

Differentiation between restrictive cardiomyopathy and constrictive pericarditis by early diastolic doppler myocardial velocity gradient at the posterior wall. (2/98)

BACKGROUND: The differential diagnosis between restrictive cardiomyopathy (RCM) and constrictive pericarditis (CP) is challenging and, despite combined information from different diagnostic tests, surgical exploration is often necessary. METHODS AND RESULTS: A group of 55 subjects (mean age, 63+/-11 years; 36 men and 19 women) were enrolled in the study; 15 had RCM, 10 had CP, and 30 were age-matched, normal controls. The diagnosis of RCM was supported by a biopsy; in the CP group, the diagnosis was confirmed either surgically or at autopsy. All patients underwent a transthoracic echocardiogram that included the assessment of Doppler myocardial velocity gradient (MVG), as measured from the left ventricular posterior wall during the predetermined phases of the cardiac cycle. MVG was lower (P<0.01) in RCM patients compared with both CP patients and normal controls during ventricular ejection (2. 8+/-1.2 versus 4.4+/-1.0 and 4.7+/-0.8 s(-1), respectively) and rapid ventricular filling (1.9+/-0.8 versus 8.7+/-1.7 and 3.7+/-1.4 s(-1), respectively). Additionally, during isovolumic relaxation, MVG was positive in RCM patients and negative in both CP patients and normal controls (0.7+/-0.4 versus -1.0+/-0.6 and -0.4+/-0.3 s(-1), respectively; P<0.01). During atrial contraction, MVG was similarly low (P<0.01) in both RCM and CP patients compared with normal controls (1.6+/-1.7 and 1.7+/-1.8 versus 3.8+/-0.9 s(-1), respectively). CONCLUSIONS: Doppler myocardial imaging-derived MVG, as measured from the left ventricular posterior wall in early diastole during both isovolumic relaxation and rapid ventricular filling, allows for the discrimination of RCM from CP.  (+info)

Sudden death and cardiovascular collapse in children with restrictive cardiomyopathy. (3/98)

BACKGROUND: Restrictive cardiomyopathy (RCM) is rare in children, and the prognosis is poor. In the present study, we evaluated all pediatric patients with RCM who were at our institution during a 31-year period to determine the clinical outcome and cause of death. Those who sustained sudden, unanticipated cardiac arrests were evaluated for risk factors that are predictive of sudden death. METHODS AND RESULTS: Eighteen consecutive patients were reviewed. Presentation, clinical course, laboratory data, and histopathological evidence of ischemia were compared between patients with and without sudden death events. The results demonstrated that patients who were at risk for sudden death were girls with chest pain, syncope, or both at presentation and without congestive heart failure. Although not statistically significant for sudden death, Holter monitor evidence of ischemia predicted death within months. Histopathological evidence of acute or chronic ischemia was found in the majority of patients, with acute ischemia more common among those who sustained sudden death events. CONCLUSIONS: All children with RCM are at risk for ischemia-related complications and death, and some are at risk of sudden death. In the present study, patients at risk of sudden death appeared well and had no evidence of ongoing heart failure but often had signs or symptoms of ischemia characterized by chest pain, syncope, or both. ECGs and Holter monitors may be useful screening tools. The use of beta-blockade, the placement of an implantable cardioverter-defibrillator, and preferential status 1A or B listing for cardiac transplantation are proposed for pediatric patients with RCM and evidence of ongoing ischemia.  (+info)

Heart transplantation and the Batista operation for children with refractory heart failure. (4/98)

Medically refractory heart failure may be present in children with cardiomyopathy (CMP) or complex congenital heart disease (CHD). In adults, the surgical management of this condition is either heart transplantation or the Batista operation. From March 1995 to January 2000, a total of 6 children, aged from 1 to 16 years, with medically refractory heart failure associated with CMP or complex CHD underwent cardiac transplantation and one of them also had the Batista operation as a bridge to transplantation. One of the 6 patients died of intractable sepsis 17 days after the operation, but the other 5 were discharged with satisfactory hemodynamics. Immunosuppressive agents, including azathioprine, cyclosporin or FK-506, were given. One patient experienced moderate acute rejection, but it was controlled by FK-506, OKT-3 and solumedrol. However, another suffered from lymphoproliferative disease 8 months after transplant, but it was controlled by intravenous immunoglubulin, alpha-interferon and acyclovir. Cardiac function during serial follow-up (range, 1 month to 5 years) revealed normal systolic and diastolic function and none received any anticongestive medications. Almost all patients received an oversized donor heart. The left ventricle (LV) mass was remodeled, initially as an decrease and later as an increase. The patient who underwent the Batista operation was discharged 1 month after the operation with an increased LV ejection fraction (from 10% to 22%). She was successfully bridged to heart transplantation 7 months after the Batista operation. The results of cardiac transplantation in growing children are satisfactory and remain the mainstay of surgical treatment for medically refractory heart failure in these patients. However, with a shortage of donor hearts, the Batista operation may be adopted as a bridge to heart transplant with a fair response.  (+info)

The in vivo role of p38 MAP kinases in cardiac remodeling and restrictive cardiomyopathy. (5/98)

Stress-induced mitogen-activated protein kinase (MAP) p38 is activated in various forms of heart failure, yet its effects on the intact heart remain to be established. Targeted activation of p38 MAP kinase in ventricular myocytes was achieved in vivo by using a gene-switch transgenic strategy with activated mutants of upstream kinases MKK3bE and MKK6bE. Transgene expression resulted in significant induction of p38 kinase activity and premature death at 7-9 weeks. Both groups of transgenic hearts exhibited marked interstitial fibrosis and expression of fetal marker genes characteristic of cardiac failure, but no significant hypertrophy at the organ level. Echocardiographic and pressure-volume analyses revealed a similar extent of systolic contractile depression and restrictive diastolic abnormalities related to markedly increased passive chamber stiffness. However, MKK3bE-expressing hearts had increased end-systolic chamber volumes and a thinned ventricular wall, associated with heterogeneous myocyte atrophy, whereas MKK6bE hearts had reduced end-diastolic ventricular cavity size, a modest increase in myocyte size, and no significant myocyte atrophy. These data provide in vivo evidence for a negative inotropic and restrictive diastolic effect from p38 MAP kinase activation in ventricular myocytes and reveal specific roles of p38 pathway in the development of ventricular end-systolic remodeling.  (+info)

Epidemiology of idiopathic cardiomyopathy in Japan: results from a nationwide survey. (6/98)

OBJECTIVE: To estimate the total number of patients with idiopathic cardiomyopathy in Japan and the prevalence of the disorder. DESIGN: A nationwide epidemiological survey. SETTING: Hospitals selected randomly from among all hospitals in Japan. PATIENTS: Patients presenting with any of the three types of idiopathic cardiomyopathy: dilated cardiomyopathy, hypertrophic cardiomyopathy, and restrictive cardiomyopathy. MAIN OUTCOME MEASURES: The total number of patients in Japan was estimated using the sampling and response rates in each stratum with respect to hospital size. The second survey was conducted for patients reported in the first survey in order to obtain detailed information, including age, sex, and specific clinical data. RESULTS: Estimated patient totals and 95% confidence intervals (CI) were 17 700 (95% CI 16 500 to 18 800) for dilated cardiomyopathy, 21 900 (95% CI 20 600 to 23 200) for hypertrophic cardiomyopathy, and 300 (95% CI 250 to 350) for restrictive cardiomyopathy. Crude prevalence per 100 000 population was estimated as 14.0 for dilated cardiomyopathy, 17.3 for hypertrophic cardiomyopathy, and 0.2 for restrictive cardiomyopathy; crude incidence per 100 000 person-years was estimated as 3.58, 4.14, and 0.06, respectively. CONCLUSIONS: The total number and prevalence of patients with idiopathic cardiomyopathy in Japan are estimated for the first time in a nationwide survey. The prevalence of dilated cardiomyopathy in Japan appears to be about half that of Western populations, while that of hypertrophic cardiomyopathy is about the same.  (+info)

Molecular mechanisms of inherited cardiomyopathies. (7/98)

Cardiomyopathies are diseases of heart muscle that may result from a diverse array of conditions that damage the heart and other organs and impair myocardial function, including infection, ischemia, and toxins. However, they may also occur as primary diseases restricted to striated muscle. Over the past decade, the importance of inherited gene defects in the pathogenesis of primary cardiomyopathies has been recognized, with mutations in some 18 genes having been identified as causing hypertrophic cardiomyopathy (HCM) and/or dilated cardiomyopathy (DCM). Defining the role of these genes in cardiac function and the mechanisms by which mutations in these genes lead to hypertrophy, dilation, and contractile failure are major goals of ongoing research. Pathophysiological mechanisms that have been implicated in HCM and DCM include the following: defective force generation, due to mutations in sarcomeric protein genes; defective force transmission, due to mutations in cytoskeletal protein genes; myocardial energy deficits, due to mutations in ATP regulatory protein genes; and abnormal Ca2+ homeostasis, due to altered availability of Ca2+ and altered myofibrillar Ca2+ sensitivity. Improved understanding that will result from these studies should ultimately lead to new approaches for the diagnosis, prognostic stratification, and treatment of patients with heart failure.  (+info)

Idiopathic restrictive cardiomyopathy is part of the clinical expression of cardiac troponin I mutations. (8/98)

Restrictive cardiomyopathy (RCM) is an uncommon heart muscle disorder characterized by impaired filling of the ventricles with reduced volume in the presence of normal or near normal wall thickness and systolic function. The disease may be associated with systemic disease but is most often idiopathic. We recognized a large family in which individuals were affected by either idiopathic RCM or hypertrophic cardiomyopathy (HCM). Linkage analysis to selected sarcomeric contractile protein genes identified cardiac troponin I (TNNI3) as the likely disease gene. Subsequent mutation analysis revealed a novel missense mutation, which cosegregated with the disease in the family (lod score: 4.8). To determine if idiopathic RCM is part of the clinical expression of TNNI3 mutations, genetic investigations of the gene were performed in an additional nine unrelated RCM patients with restrictive filling patterns, bi-atrial dilatation, normal systolic function, and normal wall thickness. TNNI3 mutations were identified in six of these nine RCM patients. Two of the mutations identified in young individuals were de novo mutations. All mutations appeared in conserved and functionally important domains of the gene. This article was published online in advance of the print edition. The date of publication is available from the JCI website, http://www.jci.org.  (+info)

A 16 year old male underwent evaluation for heart transplantation because of progressive dyspnoea, dizziness, and palpitations caused by restrictive cardiomyopathy of unknown aetiology which was unresponsive to conventional medical treatment. Idiopathic restrictive cardiomyopathy had been diagnosed at the age of less than 1 year and was associated with growth retardation, but no other overt congenital defects. During childhood and early adolescence the boy remained limited in his physical performance compared to his schoolmates. Since the autumn of 1997 progressive deterioration with dyspnoea and symptomatic arrhythmia such as atrial re-entry tachycardia or atrial flutter occurred and made further attendance of school almost impossible. Medical treatment was ineffective and, after clinical reassessment, the patient was put on the waiting list for heart transplantation in early 1998.. Echocardiographic examination at this time revealed the presence of biventricular diverticula located beneath the ...
Restrictive cardiomyopathy or simply RCM is the abnormal functioning of the heart muscles. Restrictive cardiomyopathy manifests itself differently to different people. While some may not experience any symptom whatsoever, there are those with reported severe symptoms. Know the causes, symptoms, treatment, prevention of restrictive cardiomyopathy
If youve ever woken up with stiff muscles, you know it can be hard to move around or perform your usual daily activities with the same ease. Similarly, our heart muscles need to stay flexible to do their job and pump blood throughout our bodies. Normally, the lower chambers of your heart open to let blood flow in and then contract to pump it back out. In restrictive cardiomyopathy, the heart muscle stiffens and is not able to stretch as it should to pump blood.. Restrictive cardiomyopathy can be caused by a number of things, including scarring of the heart from surgery and a condition called amyloidosis, where abnormal proteins build up in the heart. As restrictive cardiomyopathy progresses, you may develop heart failure. You may notice symptoms such as difficulty breathing at night or when exercising, feeling very tired, or swelling in your legs.. Treatment is usually focused on relieving symptoms and may include medications, lifestyle changes, and the use of a pacemaker to help regulate your ...
Restrictive cardiomyopathy, or restrictive cardiac disease, is defined as abnormal diastolic function in association with relatively well-preserved systolic function (at least in the early stages of the disease). Clinically, restrictive cardiomyopathy is difficult to distinguish from constrictive pericarditis, which is treatable.

Restrictive cardiomyopathy or infiltrative cardiomyopathy is a disorder of the heart muscle, in which the stiffened walls of the ventricles become resistant to adequate filling up with blood, when the heart relaxes (diastole) after every contraction, leading to heart failure.
Restrictive cardiomyopathy (RCM) is a rare disease of the myocardium and is the least common of the 3 clinically recognized and described cardiomyopathies. Its principal abnormality is diastolic dysfunction-specifically, restricted ventricular filling.
Restrictive cardiomyopathy, or RCM, is when the chambers of the heart become stiffer over time. Though the heart is able to squeeze well, it is not able to relax between beats normally. This makes it harder for the heart to fill with blood. It also increases the pressure inside the ventricles and the atria can become enlarged.
Restrictive cardiomyopathy gets its name from the way it restricts the heart from stretching properly. While the rhythm and pumping action of the heart may be healthy, the stiff walls of the heart chambers keep them from filling normally.

Restrictive cardiomyopathies (RCM) are indolent disabling diseases resulting from pathophysiologic processes that induce predominant diastolic chamber dysfunction with lesser impairment of systolic performance. RCM is characterized by small stiff ventricles with progressive impairment of diastolic filling, leading to the hemodynamic conundrum of low preload but high filling pressures (Figure 24-1). This pattern of diastolic dysfunction leads to dilated atria and elevated mean atrial pressures, resulting clinically in biventricular backward failure manifest as pulmonary venous congestion (dyspnea) as well as systemic venous pressure elevation (peripheral edema). Systolic function is preserved in most cases, depending on the underlying cause (at least in the presenting stages of most of the underlying diseases). However, despite intact systolic function, the restrictive constraints on true ventricular preload limit stroke volume, thereby resulting in low cardiac output (fatigue) and ultimately ...
Exome sequencing will be used as part of a tiered genetic analysis in a large cohort of up to 700 pediatric cardiomyopathy subjects with systolic (dilated cardiomyopathy) or diastolic (hypertrophic or restrictive cardiomyopathy) dysfunction. The biological parent(s) of enrolled participants will also be approached about participating and providing a blood sample for genetic testing. In addition to the parent(s), the participants siblings and other relatives may also be approached regarding enrollment, based on the pedigree and family history.. This study will significantly increase our understanding of pediatric cardiomyopathy by defining the prevalence of mutations in genes known to cause cardiomyopathy as well as identifying novel disease-causing genes in the pediatric population. Genetic association tests will identify variants that modify disease. Novel bioinformatics and systems biology applications for interpretation of exome level genetic information will contribute fundamental knowledge ...

Extrinsic Cardiomyopathy are a more common type of Cardiomyopathy. It is where the primary pathology is outside the myocardium. Meanwhile, intrinsic Cardiomyopathy is defined as weakness inside the muscle of the heart. There are three more specific types of Cardiomyopathy. These are Dilated Cardiomyopathy, Hypertrophic Cardiomyopathy and Restrictive Cardiomyopathy. Dilated Cardiomyopathy is the most common form. This form can lead to enlargement of the heart, especially the left ventricle, and the pumping function decreases. Hypertrophic Cardiomyopathy is when the muscle thickens, which can get in the way of the blood flow and prevents the heart to pump properly. Restrictive Cardiomyopathy is the most rarest form of Cardiomyopathy. It is when the walls of the ventricles stiffens but not thickens and can resist the normal filling of blood in the heart ...

Cardiomyopathies, like the hypertrophic, arrhythmogenic, dilatative and restrictive cardiomyopathy, are heart muscle diseases, often genetically caused. Mostly, the affected genes encode for proteins of the sarcomere. For hypertrophic cardiomyopathy, mainly the gene encoding for myosin binding protein C is affected, but also genes encoding for the subunits of the heterotrimeric troponin complex. The most frequently affected gene in restrictive cardiomyopathy is encoding for troponin I. We investigate the pathomechanisms of such mutations in genes encoding for troponin subunits in vitro on protein level as well as in isolated cardiomyocytes.. Other factors possibly leading to heart diseases are e.g. stress, hypertension, atherosclerosis, inflammation etc. Recently we demonstrated an important role of the soluble adenylyl cyclase for the development of stress-induced cardiac hypertrophy. The underlying ...
http://library.med.utah.edu/WebPath/jpeg5/CV164.jpg Hemochromatosis, with excessive iron deposition, can occur in the heart as shown here microscopically with Prussian blue iron stain. The excessive deposition of iron leads to heart enlargement and failure similar to a cardiomyopathy, making hemochromatosis a form of restrictive cardiomyopathy.

DefinitionRestrictive cardiomyopathy refers to a set of changes in how the heart muscle functions. These changes cause the heart to fill poorly (more common) or squeeze poorly (less common). Sometimes, both problems are present.
Most of the time, treatment focuses on relieving symptoms, improving heart function, and helping you live longer. You may also have other treatment for the problem that is causing restrictive cardiomyopathy, such as medicines to get rid of too much iron in the heart muscle (hemochromatosis).. You will probably need to take several medicines to treat heart failure caused by restrictive cardiomyopathy. Its important to take your medicines exactly as your doctor tells you to and to keep taking them. If you dont, your heart failure could get worse.. Your doctor may suggest a mechanical device to help your heart pump blood or prevent life-threatening irregular heart rhythms. Such devices include a pacemaker, an implantable cardioverter-defibrillator (ICD), or a combination pacemaker and ICD. If your condition is very bad, a heart transplant may be an option.. Self-care is an important part of your treatment. Self-care includes the things you can do every day to feel better, stay healthy, and avoid ...

Sometimes the walls of the hearts lower chambers (ventricles) become so much rigid that they are unable to expand even after filled with blood.
Thanks for visiting,. Carol and David DiFiori. In February, 2007, at age eight, Duncan was diagnosed with both CRF and restrictive cardiomyopathy. After nearly ten CRF-free years, we again resumed the role of caregivers. We rode the emotional roller coaster for nearly four years. We have written a journal about our experience with this unexpected diagnosis and the steps we took to help Duncan. Duncan brightened our lives with his happy-go-lucky, spirited, loving and affectionate personality. We have placed a photograph of Duncan in the Memorial Gallery and we have put a Tribute in the Tribute Gallery.. On July 4, 2012, we said goodbye to the sweetest, gentlest and most graceful cat there ever was. Joseph was Duncans littermate and brother and outlived him by a year and a half. We treasured every second with Joseph.. He, too, was diagnosed with both CRF and restrictive cardiomyopathy and other conditions. . His Memorial photo and Tribute are online.. Thank you for your beautiful, caring, ...

Patients with heart failure can roughly be divided into two groups: those with ventricular dysfunction due to ischaemia and those with a non-ischaemic heart disease. Most of the different forms of cardiomyopathy in the last group can have a distinct cause like hypertension or a valvular heart disease. However in an important subset of these no such cause is identified thereby obtaining the classification idiopathic cardiomyopathy. The familial character of these different forms of idiopathic cardiomyopathy has been recognized in many studies.. Four categories of disease are distinghuised and the basis of haemodynamical and morphological characteristics: hypertrophic cardiomyopathy (HCM), dilated cardiomyopathy (DCM), restrictive cardiomyopathy (RCM) and arrhythmogenic right ventricular cardiomyopathy (ARVC).. HCM is characterised by (usually asymmetric) left ventricular hypertrophy. In myocardial biopsies, myofibrillar disarray and myocyte hypertrophy is seen. Arrhythmias and premature sudden ...

Congenital or neonatal cardiomyopathies are commonly associated with a poor prognosis and have multiple etiologies. In two siblings, a male and female, we identified an undescribed type of lethal congenital restrictive cardiomyopathy affecting the right ventricle. We hypothesized a novel autosomal recessive condition. To identify the cause, we performed genetic, in vitro and in vivo studies. Genome-wide SNP typing and parametric linkage analysis was done in a recessive model to identify candidate regions. Exome sequencing analysis was done in unaffected and affected siblings. In the linkage regions, we selected candidate genes that harbor two rare variants with predicted functional effects in the patients and for which the unaffected sibling is either heterozygous or homozygous reference. We identified two compound heterozygous variants in KIF20A; a maternal missense variant (c.544C|T: p.R182W) and a paternal frameshift mutation (c.1905delT: p.S635Tfs*15). Functional studies confirmed that the R182W
Amongst adult cats, myocardial disease (cardiomyopathy) is the most common form of heart disease. Hypertrophic cardiomyopathy (HCM) is identified in over 60% of cardiomyopathic cats, with the rest attributable to dilated cardiomyopathy, restrictive cardiomyopathy (endomyocardial or myocardial), arrhythmogenic right ventricular cardiomyopathy, and unclassified cardiomyopathy.. The criteria by which each form of cardiomyopathy is defined are based on echocardiographically-derived parameters; however, there is some overlap between categories, which results in controversy over the classification of some individuals. Of greater importance for these individuals is correct identification of the type of functional abnormality (e.g., systolic dysfunction, diastolic dysfunction, or both), as this has direct implications for patient management.. While pathophysiology of the feline cardiomyopathies differs, affected cats are at risk for the same three adverse sequelae: congestive failure, thromboembolic ...

N2 - Cardiomyopathies in children encompass a broad range of diseases, both genetic and acquired, which manifest as a primary cardiac disorder or as a cardiomyopathy secondary to systemic disease. The burden of this group of disorders is substantial, and growing on a global scale. The availability of disease altering treatments is limited, and therefore a focused review on the prevention of cardiomyopathies is justified. In this review, we address the prevention of cardiomyopathy in children by dealing with the root causes of disease at a molecular, clinical and population level. Recent years have yielded ...
Morphologic features of the main types of cardiomyopathies. The normal geometry of the LV is shown. In comparison, there is enlargement and dilatation of the LV in DCM. In HCM, there is marked thickening of the LV wall, often asymmetric, with the septum being even thicker than the free wall of the LV. In restrictive cardiomyopathy (RCM), the ventricular wall may be normal, hypertrophic, or slightly dilated, but the main feature is that the restriction to diastolic compliance of the ventricl ...
The contractile response of the heart can be altered by disease-related protein modifications to numerous contractile proteins. By utilizing an IAANS labeled fluorescent troponin C, [Formula: see text], we examined the effects of ten disease-related troponin modifications on the Ca(2+) binding properties of the troponin complex and the reconstituted thin filament. The selected modifications are associated with a broad range of cardiac diseases: three subtypes of familial cardiomyopathies (dilated, hypertrophic and restrictive) and ischemia-reperfusion injury. Consistent with previous studies, the majority of the protein modifications had no effect on the Ca(2+) binding properties of the isolated troponin complex. However, when incorporated into the thin filament, dilated cardiomyopathy mutations desensitized (up to 3.3-fold), while hypertrophic and restrictive cardiomyopathy mutations, and ischemia-induced truncation of troponin I, sensitized the thin filament to Ca(2+) (up to 6.3-fold). Kinetically,

Our study, which includes the largest series so far of patients with TTR-related CA comprehensively studied by both conventional echocardiography and 2D STI, supports the role of myocardial deformation imaging as a sensitive tool for characterizing LV dysfunction in CA over more traditional echocardiographic parameters. Our findings provide insights into the pathophysiological mechanisms underlining LV dysfunction in amyloid heart disease, suggesting a role for specific pathogenesis and LV wall thickness in determining LV dysfunction. Along with pathogenesis, LV LS was found to be an independent predictor of overall survival, confirming the previously observed prognostic significance of strain in patients with AL amyloidosis.. CA is commonly considered a form of restrictive cardiomyopathy, and the pathophysiology of HF has traditionally been attributed to diastolic dysfunction. Only a few studies have assessed the individual contributions of systolic and diastolic dysfunction to the ...

Mid June the Echocardiogram was reviewed and it was clear that the heart had worsened. The question was why. It could be idiopathic, amyloidosis, multiple myeloma or some other rare infiltrative process. It was time to break the silence. Barbie sent out an email to a few friends in California and Connecticut and we told our family. On July 1st, I informed my partners in our monthly meeting that I had restrictive cardiomyopathy and was waiting for a biopsy to determine if it was amyloidosis. I said I would continue to work. The news spread like wildfire. The response was overwhelming and somewhat difficult for me to adjust to. I was not accustom to being the individual in need; my role was always the opposite, to support others in their suffering. I did not want people to worry about me. This would begin a huge personal transformation in how I saw myself and the need to always be in control. This would be a very important life lesson for me.. I was scheduled for a fat biopsy and referred to the ...

Christopher had a successful heterotopic, or piggyback, heart transplant on Oct. 8,1997. He was born May 7, 1990 and was sick all his life with severe restrictive cardiomyopathy and secondary pulmonary hypertension. But, other than that, Christopher seemed healthy and just kept getting happier and happier with life. Our beautiful blond-haired, brown-eyed boy lifted his head, roiled over, crawled, walked and talked just like any other child. We decided to put off the transplant as long as he was doing okay. He was definitely our miracle child. He refused to give in to the heart disease. He was the joy of our lives. But you would never have known he was sick just looking at him or talking with him ...

Jesica Santillan was a seventeen-year-old young lady who was born in Mexico with restrictive cardiomyopathy. Her parents paid smugglers 5,000 dollars to smuggle her and her two siblings over the Mexican-US border in order to obtain healthcare for her in the United States.. On their journey, the family was robbed by thieves who stole all of their money and even Jesicas earrings. They settled in North Carolina in a caravan, where her father and mother found work. Jesica came to be under the care of Dr James Jaggers, a very well respected surgeon and humanitarian at Duke University Hospital.. Soon after the Santillans arrived in North Carolina they drew the attention of compassionate locals like Mack Mahoney who became a fierce advocate for Jesica and her family, starting an organisation called Jesicas Hope Chest to raise funds for her surgery and the familys living expenses. He was such a trusted advocate for Jesica that her family allowed him to make surrogate medical decisions on her ...
