Macromolecular organic compounds that contain carbon, hydrogen, oxygen, nitrogen, and usually, sulfur. These macromolecules (proteins) form an intricate meshwork in which cells are embedded to construct tissues. Variations in the relative types of macromolecules and their organization determine the type of extracellular matrix, each adapted to the functional requirements of the tissue. The two main classes of macromolecules that form the extracellular matrix are: glycosaminoglycans, usually linked to proteins (proteoglycans), and fibrous proteins (e.g., COLLAGEN; ELASTIN; FIBRONECTINS; and LAMININ).

Furin initiates gelsolin familial amyloidosis in the Golgi through a defect in Ca(2+) stabilization. (1/67)

Hereditary familial amyloidosis of Finnish type (FAF) leading to amyloid in the peripheral and central nervous systems stems from deposition of a 71 residue fragment generated from the D187N/Y variants of plasma gelsolin by two sequential endoproteolytic events. We identify the protease accomplishing the first cleavage as furin, a proprotein convertase. Endoproteolysis of plasma gelsolin occurs in the trans-Golgi network due to the inability of the FAF variants to bind and be stabilized by Ca(2+). Secretion and processing of the FAF variants by furin can be uncoupled by blocking the convergence of the exocytic pathway transporting plasma gelsolin and the endocytic recycling of furin. We propose that coincidence of membrane trafficking pathways contributes to the development of proteolysis-initiated amyloid disease.  (+info)

Misdiagnosis of hereditary amyloidosis as AL (primary) amyloidosis. (2/67)

BACKGROUND: Hereditary, autosomal dominant amyloidosis, caused by mutations in the genes encoding transthyretin, fibrinogen A alpha-chain, lysozyme, or apolipoprotein A-I, is thought to be extremely rare and is not routinely included in the differential diagnosis of systemic amyloidosis unless there is a family history. METHODS: We studied 350 patients with systemic amyloidosis, in whom a diagnosis of the light-chain (AL) type of the disorder had been suggested by clinical and laboratory findings and by the absence of a family history, to assess whether they had amyloidogenic mutations. RESULTS: Amyloidogenic mutations were present in 34 of the 350 patients (9.7 percent), most often in the genes encoding fibrinogen A alpha-chain (18 patients) and transthyretin (13 patients). In all 34 of these patients, the diagnosis of hereditary amyloidosis was confirmed by additional investigations. A low-grade monoclonal gammopathy was detected in 8 of the 34 patients (24 percent). CONCLUSIONS: A genetic cause should be sought in all patients with amyloidosis that is not the reactive systemic amyloid A type and in whom confirmation of the AL type cannot be obtained.  (+info)

Mutational spectrum in the MEFV and TNFRSF1A genes in patients suffering from AA amyloidosis and recurrent inflammatory attacks. (3/67)

BACKGROUND: Among hereditary fevers characterized by recurrent attacks of fever and organ localized inflammation, familial Mediterranean fever (FMF), and tumour necrosis factor receptor superfamily 1A (TNFRSF1A) receptor associated periodic syndrome (TRAPS) are diseases with identified genes that can be associated with renal amyloidosis of the AA type. In this study we have characterized FMF and TRAPS genotypes in 38 unrelated patients suffering from amyloidosis AA and recurrent inflammatory attacks. METHODS: Mutations of the MEFV and TNFRSF1A genes, responsible respectively for FMF and TRAPS, were searched for by amplifying, using polymerase chain reaction (PCR), genomic DNA, and direct sequencing. RESULTS: Twenty-seven patients (71%) carried mutations in MEFV (22 patients with two mutations, two patients with a single mutation) or TNFRSF1A genes (three patients). Patients with MEFV mutations belonged to the classical at-risk ethnic group for FMF: Sephardic Jews, Turks, Armenians, and Arabs from the Maghreb. The main genotype encountered was M694V/M694V (19/22), one Turkish patient was M680I/M680I, and two Arab patients from the Maghreb were M694I/M694I. We found three Caucasian patients with the C55S, C70Y, R92Q mutations in the TNFRSF1A gene. CONCLUSIONS: In this series we observed that FMF is the main cause of AA amyloidosis in Sephardic Jews and Turks. MEFV and TNFRSF1A mutations were found in only 6 of 14 Arab patients from the Maghreb. We found three families (one Caucasian and two from Maghreb) with AA amyloidosis without MEFV or TNFRSF1A mutations, suggesting that other genetic cause(s) exist(s). The characterization of mutations in MEFV and TNFRSF1A is important for the therapeutic behaviour of AA amyloidosis associated with inherited recurrent fever.  (+info)

Immunoglobulin light chain variable (V) region genes influence clinical presentation and outcome in light chain-associated amyloidosis (AL). (4/67)

Light chain-associated amyloidosis (AL) is a plasma cell dyscrasia in which the secreted monoclonal immunoglobulin (Ig) light chains form amyloid fibrils. There is considerable heterogeneity in clinical presentation, and prognosis of the disease relates to the severity of organ dysfunction induced by amyloid deposits. The mechanisms by which the amyloid fibrils are deposited as well as the predilection for specific organ sites have not been clearly elucidated. This study characterizes the repertoire of immunoglobulin light chain variable genes used by the clonal B cell in AL amyloid patients, and the association of light chain variable region (VL) genes with clinical presentation and outcome is assessed in 58 (32 lambda and 26 kappa) patients. A preferential use of VL germ-line genes was noted for both AL kappa and lambda patients. There was a significant correlation between the use of the Vlambda VI germ-line donor, 6a, and renal involvement as well as the Vlambda III gene, 3r, with soft-tissue AL. The use of a biased VL gene repertoire also correlated with clinical outcome, revealing important trends for predicting prognosis. The use of Vlambda II germ-line genes was associated with cardiac amyloidosis and affected survival adversely. The presence of multiple myeloma also correlated with a poor prognosis. The presence of renal disease, on the other hand, was associated with improved survival. Therefore, identification of the clonal VL gene in AL has important implications in determining clinical outcome.  (+info)

Simulations of human lysozyme: probing the conformations triggering amyloidosis. (5/67)

A natural mutant of human lysozyme, D67H, causes hereditary systemic nonneuropathic amyloidosis, which can be fatal. In this disease, insoluble beta-stranded fibrils (amyloids) are found in tissues stemming from the aggregation of partially folded intermediates of the mutant. In this study, we specifically compare the conformation and properties of the structures adopted from the induced unfolding, at elevated temperature, using molecular dynamics. To increase the sampling of the unfolding conformational landscape, three 5 ns trajectories are performed for each of the wild-type and mutant D67H proteins resulting in a total of 30 ns simulation. Our results show that the mutant unfolds slightly faster than the wild-type with both wild-type and mutant proteins losing most of their native secondary structure within the first 2 ns. They both develop random transient beta-strands across the whole polypeptide chain. Clustering analysis of all the conformations shows that a high population of the mutant protein conformations have a distorted beta-domain. This is consistent with experimental results suggesting that this region is pivotal in the formation of conformations prone to act as "seeds" for amyloid fiber formation.  (+info)

Identification of S-sulfonation and S-thiolation of a novel transthyretin Phe33Cys variant from a patient diagnosed with familial transthyretin amyloidosis. (6/67)

Familial transthyretin amyloidosis (ATTR) is an autosomal dominant disorder associated with a variant form of the plasma carrier protein transthyretin (TTR). Amyloid fibrils consisting of variant TTR, wild-type TTR, and TTR fragments deposit in tissues and organs. The diagnosis of ATTR relies on the identification of pathologic TTR variants in plasma of symptomatic individuals who have biopsy proven amyloid disease. Previously, we have developed a mass spectrometry-based approach, in combination with direct DNA sequence analysis, to fully identify TTR variants. Our methodology uses immunoprecipitation to isolate TTR from serum, and electrospray ionization and matrix-assisted laser desorption/ionization mass spectrometry (MS) peptide mapping to identify TTR variants and posttranslational modifications. Unambiguous identification of the amino acid substitution is performed using tandem MS (MS/MS) analysis and confirmed by direct DNA sequence analysis. The MS and MS/MS analyses also yield information about posttranslational modifications. Using this approach, we have recently identified a novel pathologic TTR variant. This variant has an amino acid substitution (Phe --> Cys) at position 33. In addition, like the Cys10 present in the wild type and in this variant, the Cys33 residue was both S-sulfonated and S-thiolated (conjugated to cysteine, cysteinylglycine, and glutathione). These adducts may play a role in the TTR fibrillogenesis.  (+info)

Safety of colchicine therapy during pregnancy. (7/67)

QUESTION: A 27-year-old patient in our clinic with familial Mediterranean fever (FMF) has been treated with colchicine for the last decade. She is planning her first pregnancy. What recommendations should we give her regarding use of colchicine before and during pregnancy, bearing in mind that discontinuation of colchicine could lead to complications from amyloidosis? ANSWER: Colchicine passes through the placenta in humans, is teratogenic in animals, and raises rates of male and female infertility. Based on several patients with chromosomal anomalies, some authorities recommend that patients who require colchicine therapy during pregnancy undergo amniocentesis with karyotyping. In contrast, an increasing body of evidence suggests that colchicine use throughout pregnancy carries no substantial teratogenic or mutagenic risk when used at recommended doses. Its use prevents febrile attacks of FMF and reduces the frequency of renal complications.  (+info)

Cysteine 10 is a key residue in amyloidogenesis of human transthyretin Val30Met. (8/67)

Type I familial amyloidotic polyneuropathy (FAP), a systemic amyloidosis, is characterized by aggregation of variant transthyretin (TTR Val30Met) into stable, insoluble fibrils. This aggregation is caused by genetic and environmental factors. Genetic factors have been studied extensively. However, little is known about environmental or physiological factors involved in the disease process, and their identification may be important for development of effective treatment. X-ray crystallography of normal and amyloidogenic human TTR Val30Met in type I FAP showed that the -SH side chain of cysteine at position 10 (Cys10) forms a hydrogen bond with Gly57 in normal TTR but not in TTR Val30Met. This result suggests a crucial role for the free Cys10 residue and possible involvement of physiological factors affecting Cys residue reactivity in TTR amyloidogenesis. To analyze amyloidogenesis in vivo, our group generated murine FAP models by transgenic technology, with human TTR Val30Met. The three lines of transgenic mice expressed amyloidogenic mutant TTR (Cys10/Met30), wild-type TTR (Cys10/Val30), and artificial Cys-free mutant TTR (Ser10/Met30). Histochemical investigation showed deposition of amyloid derived from human TTR only in amyloidogenic mutant TTR (Cys10/Met30) mice. Thus, the -SH residue in Cys10 plays a crucial role in TTR Val30Met amyloidogenesis in vivo. These data suggest the possibility of innovative treatment via physiological factors modulating Cys10 residue reactivity.  (+info)

Any of a group of diseases or conditions characterized by the formation and deposition of amyloid in various organs and tissues of the body.
Background. Familial Amyloidosis with Polyneuropathy (FAP) is an autosomal dominantly inherited systemic amyloid disease. The disease is caused by mutations in the transthyretin (TTR) gene, where close to 100 different amyloidogenic mutations have been identified. FAP is found worldwide, but endemic areas with a high frequency of patients are found in Portugal, Japan and northern Sweden. Cases from these endemic areas all share the same TTR c.148G,A, p.V50M (V30M) mutation, but the phenotype of the disease varies between the areas, and also within the endemic areas. The mean onset of the disease is two decades earlier in Portugal and Japan compared to Sweden, but late as well as early age at onset cases occur within all the populations. Interestingly, the different populations all display a maternal anticipation, where an earlier onset is observed for those individuals who inherit the trait from their mother. Since substantial variation in the phenotype is observed for different populations, ...

Gelatinous drop-like corneal dystrophy, also known as amyloid corneal dystrophy, is a rare form of corneal dystrophy. The disease was described by Nakaizumi as early as 1914. The main pathological features in this dystrophy are mulberry-shaped gelatinous masses beneath the corneal epithelium. Patients suffer from photophobia, foreign body sensation in the cornea. The loss of vision is severe. The amyloid nodules have been found to contain lactoferrin, but the gene encoding lactoferrin is unaffected. This form of corneal amyloidosis appears to be more frequent in Japan. A number of mutations causing this disease have been described in the M1S1 (TACSTD2) gene encoding Tumor-associated calcium signal transducer 2, but not all patients have these mutations, suggesting involvement of other genes. Recurrence within a few years occurs in all patients following corneal transplantation. Soft contact lenses are effective in decreasing recurrences. Nakaizumi, K. : A rare case of corneal dystrophy.

In this study, we have identified two novel homozygous mutations from 3 unrelated GDLD patients with a phenotype well co-segregated with the genotype within their respective families. The insertional mutation of TACSTD2 that was found in 2 of the GDLD patients may have resulted from a flame-shift amino acid alteration with premature termination (p.Ile281SerfsX23) within the transmembrane domain. A substitutive mutation found in 1 of the GDLD patients may have resulted from a nonsense mutation (p.Tyr225X) within a region between the thyroglobulin type-1 and transmembrane domains. The transmembrane domain should support the hydrophobic scaffold which may be fundamental to the membrane binding property of this protein. However, and as far as we know, such a domain structure is only a computationally speculated model from the primary amino acid structure of this protein. Therefore, the subcellular localization of both the wild-type and mutated TACSTD2 proteins was experimentally determined in this ...
We identified amyloid derived from a mutant fibrinogen A alpha chain associated with one of the hereditary amyloidoses by kidney biopsy. The recognition of molecular and etiologic diversity among amyloidoses has revolutionized the management of systemic amyloidosis and necessitates precision in amyloid typing. Pitfalls and recommendations for the differential diagnosis of renal amyloid and current standards of amyloid typing are briefly discussed. Diagnosis of the amyloidosis type must be based on identification of the chemical composition of the amyloid protein in deposits and not on clinical suspicion, laboratory tests, or genetic testing. A clinical correlation is required to support but not make a diagnosis of amyloid type. If a hereditary form is detected by amyloid protein typing, then molecular studies are indicated. Conversely, in cases in which DNA sequence indicates a mutant amyloid precursor protein, protein analysis of the deposits must provide the definitive evidence. Negative or ...
Localized cutaneous amyloidosis (LCA) refers to a condition characterized by the deposition of amyloid or amyloid-like proteins in the dermis. Localized cutaneous amyloidosis encompasses several conditions characterized by amyloid deposition, including macular amyloidosis and lichen amyloidosis.
We found a fresh C-terminal amyloidogenic variant of apolipoprotein AI (apoAI), Leu178His inside a People from france kindred, associated with cardiac and larynx amyloidosis and skin lesions with onset during the fourth decade. plasma TTR circulates in plasma bound to high-density lipoprotein and that this interaction happens through binding to apoAI. Consequently we hypothesize that nonmutated TTR might influence deposition of apoAI as amyloid. Hereditary amyloidosis is definitely a group of late-onset autosomal dominating diseases with amyloid deposition in various cells. 1 Although a few, such as Alzheimers disease, give rise to localized disorders, most forms of amyloidosis have systemic distribution. The most frequent form of systemic hereditary amyloidosis is definitely associated with variant forms of transthyretin (TTR) 2 and causes both neuropathies and cardiomyopathies. Several other GW-786034 proteins will also be responsible for varied clinical forms of hereditary amyloidosis: ...
Introduction. Gelatinous drop-like corneal dystrophy (GDLD, OMIM 204870) is an abnormality, characterized by subepithelial deposits of amyloid and severe impairment of visual acuity leading to blindness. GDLD is an autosomal recessive disorder, described primarily in Japanese patients with an estimated prevalence of 1 in 30,000 [1-5]. It occurs also in Vietnamese [6], Indian [7,8], and Tunisian [8-10] families. A few cases have been reported in European and North American patients [8,11-13]. Early clinical symptoms of GDLD include blurred vision, severe photophobia, and ocular foreign body sensation. As the disease progresses, raised gelatinous masses accumulate on the cornea, which impair severely the visual acuity. Repeated lamellar or perforating keratoplasties is presently the only treatment option, but they do not prevent recurrence [14]. Homozygous or compound heterozygous mutations in the M1S1 (alias TROP-2) gene seem to be causative for GDLD in Japanese families [15]. The gene location ...

The UK ATTR Amyloidosis Patients Association (UKATPA) was founded in 2017 by a group of UK patients with transthyretin (TTR)-type systemic amyloidosis (ATTR), supported by the consultant physicians of the UK NHS National Amyloidosis Centre.. In recent years there have been major advances in the field of ATTR amyloidosis. The processes responsible for formation of TTR amyloid have been elucidated for the first time and intense activity in drug development promises the early advent of potentially effective prophylactic and disease modifying new medicines. Hereditary ATTR amyloidosis, caused by mutations in the TTR gene, is the most common form of hereditary amyloidosis but is nonetheless very rare. However, crucially, there is now compelling evidence that acquired ATTR amyloidosis, caused by normal wild type TTR, is far more common than was previously believed.. In this exciting environment of change and optimism, our members decided to found a UK patient group dedicated to the interests of ...
Concepts and semantics are crucial for good communication between clinicians and pathologists. Amyloidosis was described more than 150 years ago. Therefore, the terminology related to it is abundant, varied, and sometimes complex. In this report, we intend to discuss several terms related to the disease, with special emphasis on cutaneous amyloidosis. We present a review, from Virchow to present, of the concepts related to amyloidosis: its nature, the classification of cutaneous forms of the disease, and the techniques used in its diagnosis.
DIAGNOSIS. A thorough physical exam and a detailed and accurate account of your medical history are crucial in helping your doctor diagnose amyloidosis. Sophisticated laboratory techniques called electrophoresis or free light chain assays may reveal early evidence of some amyloid proteins.. A diagnosis of amyloidosis is confirmed through biopsy.

Renal amyloidosis is a glomerulopathy resulting from glomerular deposition of insoluble fibrillar proteins in the mesangium of the glomerulus. Definition, classification, epidemiology, clinical presentation, diagnosis, and treatment of amyloidosis: see Amyloidosis.. Diagnosis is confirmed by the presence of amyloid protein on immunofluorescence and electron microscopy. Many different types of amyloid protein exist, but the two most common subtypes are AL and AA amyloid:. 1) AL amyloidosis is the most common renal amyloidosis. It results in organized deposits of light chains in the glomerulus. Renal involvement occurs in approximately 50% of patients and manifests as decreased renal function and proteinuria. Nephrotic syndrome can occur. Hypertension is usually absent and the kidneys are often enlarged. Renal treatment response is related to the degree of improvement in light chain production from the underlying condition. Proteinuria and renal function improve with successful therapy.. 2) AA ...
Amyloidosis refers to a group of conditions in which proteins (amyloids) accumulate in the bodys organs and tissues in abnormal amounts, disrupting normal functions. Amyloidosis may be caused by a bone marrow cell disorder or an inherited protein variation. Or it may be associated with other conditions, including chronic infections or chronic inflammatory diseases.. Organs most often affected by amyloidosis include the heart, liver, kidney, skin, and certain nerves. But any organ system may be involved. Symptoms of amyloidosis depend upon the organ system affected and may not help determine what condition is causing the protein accumulation. Amyloidosis can be disabling and even life-threatening.. Treatment of amyloidosis depends upon the condition that is causing the protein accumulation. Treatment options may include medicine or stem cell transplant.. ...

Before taking the steps to participate in any of our research projects, please read the article here.. Amyloidosis. Lead contact: Maria Longeri - University of Milan ([email protected]). Introduction. Amyloidosis is characterized by abnormal deposits of a protein complex (amyloid) in tissues and organs, which affects their functions and eventually can lead to organ failure and death. It occurs in both wild and domestic felids, including random-bred cats. Amyloidosis is well known as a familial trait in the Abyssinian/Somali breeds that mainly affects the kidneys, and in the Siamese/Oriental breeds that mainly affects the liver.. In humans, several types of amyloidosis exist and are associated with myeloma, Alzheimers disease, and chronic inflammatory diseases. Single genes have also been identified as causes for different inherited forms of amyloidosis. Therefore, Feline Amyloidosis is an interesting model for understanding the cause and development of the similar human ...

Drs Acharya, Grogan and Abou-Ezzeddine from Mayo discuss amyloid and TTR cardiac amyloidosis, with particular focus on diagnostic challenges and use of the pyrophosphate (PYP) scan.
Researchers at Princess Alexandra Hospital, Brisbane, Australia, have demonstrated that cardiac amyloidosis (abnormal deposits of proteins in the heart), which is notoriously difficult to diagnose, can be visualized noninvasively with positron emission tomography (PET) using the radiotracer fluorine-18 (F-18)-florbetaben. The study is published in the November issue of The Journal of Nuclear Medicine.
In this study, we tested the utility of a modified DE-CMR protocol to provide diagnostic and prognostic information in patients referred for suspected cardiac amyloidosis. Although several investigations have described a characteristic pattern on conventional DE-CMR-diffuse global subendocardial HE with variable epicardial extension (4-9)-it is commonly reported that imaging is difficult and that quality is often suboptimal (5-7,9,24). This is because conventional DE-CMR relies on correctly setting an imaging parameter (inversion time) to null signal from normal myocardium, yet normal myocardium may be absent in CA.. We used a T1 assessment sequence similar to that employed by Maceira et al. (5) But, rather than quantitatively calculating T1 offline in an effort to examine gadolinium kinetics, our goal was to prospectively test a practical approach to acquiring and interpreting the images in a real-life referral population. Our visual T1 assessment approach was based on the concept that to ...

In the kidneys, as a result of benign arterial hypertension, hyaline (pink, amorphous, homogeneous material) accumulates in the walls of small arteries and arterioles, producing the thickening of their walls and the narrowing of the arterial openings, a process known as arteriolosclerosis. The resulting inadequate blood flow produces tubular atrophy, interstitial fibrosis, and glomerular alterations (smaller glomeruli with different degrees of hyalinization - from mild to sclerosis of glomeruli) and scarring around the glomeruli (periglomerular fibrosis). In advanced stages, kidney failure will occur. Functional nephrons[5] have dilated tubules, often with hyaline casts in the opening of the tubules. Additional complications often associated with hypertensive nephropathy include glomerular damage resulting in protein and blood in the urine. Hypertensive nephropathy refers to kidney failure that can be attributed to a history of hypertension[6] It is a chronic condition and it is a serious risk ...
The word tachycardia came to English from New Latin as a neoclassical compound built from the combining forms tachy- + -cardia, which are from the Greek ταχύς tachys, "quick, rapid" and καρδία, kardia, "heart". As a matter both of usage choices in the medical literature and of idiom in natural language, the words tachycardia and tachyarrhythmia are usually used interchangeably, or loosely enough that precise differentiation is not explicit. Some careful writers have tried to maintain a logical differentiation between them, which is reflected in major medical dictionaries[7][8][9] and major general dictionaries.[10][11][12] The distinction is that tachycardia be reserved for the rapid heart rate itself, regardless of cause, physiologic or pathologic (that is, from healthy response to exercise or from cardiac arrhythmia), and that tachyarrhythmia be reserved for the pathologic form (that is, an arrhythmia of the rapid rate type). This is why five of the previously referenced ...

This test measures the changes in body weight, urine output, and urine composition when fluids are withheld to induce dehydration. The body's normal response to dehydration is to conserve water by concentrating the urine. Those with DI continue to urinate large amounts of dilute urine in spite of water deprivation. In primary polydipsia, the urine osmolality should increase and stabilize at above 280 Osm/kg with fluid restriction, while a stabilization at a lower level indicates diabetes insipidus.[10] Stabilization in this test means, more specifically, when the increase in urine osmolality is less than 30 Osm/kg per hour for at least three hours.[10] Sometimes measuring blood levels of ADH toward the end of this test is also necessary, but is more time consuming to perform.[10] To distinguish between the main forms, desmopressin stimulation is also used; desmopressin can be taken by injection, a nasal spray, or a tablet. While taking desmopressin, a patient should drink fluids or water only ...

The goals of treatment are to slow the progression of kidney damage and control related complications. Management of diabetic nephropathy currently centers over four main areas: Cardiovascular risk reduction, glycemic control, blood pressure control as well as inhibition of the RAAS system.[citation needed] Cardiovascular risk reduction: Patients with diabetes mellitus are at significantly increased risk of cardiovascular disease, which is also an independent risk factor for kidney failure. Therefore, it is important to aggressively manage cardiovascular risk factors in patients diagnosed with DM in general and DN specifically. The main components of managing cardiovascular disease is with tobacco cessation, lipid-lowering therapies (eg, statins) as well as regular exercise and healthy eating.[32] In patients with kidney disease, atorvastatin is preferred over other statins as it does not require dose-adjustment based on GFR.[33] Glycemic control: Multiple studies have found a positive effect of ...

LGL syndrome is diagnosed in a person who has experienced episodes of abnormal heart racing (arrhythmias) who has a PR interval less than or equal to 0.12 second (120 ms) with normal QRS complex configuration and duration on their resting ECG.[1] A short PR interval found incidentally on an ECG without episodes of tachycardia is simply a benign ECG variant. LGL can be distinguished from WPW syndrome because the delta waves seen in WPW syndrome are not seen in LGL syndrome. The QRS complex will also be narrow in LGL syndrome, as opposed to WPW, because ventricular conduction is via the His-Purkinje system. Lown-Ganong-Levine syndrome is a clinical diagnosis that came about before the advent of electrophysiology studies. It is important to be aware that not all WPW ECGs have a delta wave; the absence of a delta wave does not conclusively rule out WPW. ...
... s (PJCs), also called atrioventricular junctional premature complexes or junctional extrasystole, are premature cardiac electrical impulses originating from the atrioventricular node of the heart or "junction". This area is not the normal but only a secondary source of cardiac electrical impulse formation. These premature beats can be found occasionally in healthy people and more commonly in some pathologic conditions, typically in the case of drug cardiotoxicity, electrolyte imbalance, mitral valve surgery, and cold water immersion.[1] If more than two such beats are seen, then the condition is termed junctional rhythm. On the surface ECG, premature junctional contractions will appear as a normally shaped ventricular complex or QRS complex, not preceded by any atrial complex or P wave or preceded by an abnormal P wave with a shorter PR interval. Rarely, the abnormal P wave can follow the QRS.[2] ...

After any PVC there is a pause that can lead to the development of bigeminy. A PVC wavefront often encounters a refractory AV node that does not conduct the wavefront retrograde. Thus the atrium is not depolarized and the sinus node is not reset. Since the sinus p wave to PVC interval is less than the normal P-P interval, the interval between the PVC and the next p wave is prolonged to equal the normal time elapsed during two P-P intervals. This is called a "compensatory" pause. The pause after the PVC leads to a longer recovery time, which is associated with a higher likelihood of myocardium being in different stages of repolarization. This then allows for re-entrant circuits and sets up the ventricle for another PVC after the next sinus beat.[2] The constant interval between the sinus beat and PVC suggests a reentrant etiology rather than spontaneous automaticity of the ventricle.[3] Atrial premature complexes (APCs) do not have a compensatory pause since they reset the sinus node but atrial ...

... and myocardial infarction are sometimes used as synonyms, although this is technically inaccurate as the thrombosis refers to the blocking of blood vessels with a thrombus, while myocardial infarction refers to heart tissue death due to the consequent loss of blood flow to the heart. Due to extensive collateral circulation, a coronary thrombus does not necessarily cause tissue death and may be asymptomatic.[citation needed] The formation of coronary thrombosis generally follows the same mechanism as other blood clots in the body, the coagulation cascade. Also applicable is the Virchow's triad of blood stasis, endothelial injury, and hypercoagulable state. Atherosclerosis contributes to coronary thrombosis formation by facilitating blood stasis as well as causing local endothelial injury.[citation needed] Due to the large number of cases of myocardial infarction leading to death and disease in the world, there has been extensive study towards the generation of clots ...

Typically an attack occurs without warning, leading to sudden loss of consciousness.[4] Prior to an attack, a patient may be pale with hypoperfusion. Abnormal movements may be present, typically consisting of twitching after 15-20 seconds of unconsciousness. (These movements, which are not seizures, occur because of brainstem hypoxia and not due to cortical discharge as is the case for epileptiform seizures). Breathing typically continues normally throughout the attack, and, upon recovery, the patient becomes flushed as the heart rapidly pumps the oxygenated blood from the pulmonary beds into the systemic circulation, which has become dilated due to hypoxia.[5] As with any syncopal episode that results from a cardiac dysrhythmia, the fainting does not depend on the patient's position. If it occurs during sleep, the presenting symptom may simply be feeling hot and flushed on waking.[5][6] ...
An ectopic pacemaker or ectopic focus is an excitable group of cells that causes a premature heart beat outside the normally functioning SA node of the heart. It is thus a cardiac pacemaker that is ectopic, producing an ectopic beat. Acute occurrence is usually non-life-threatening, but chronic occurrence can progress into tachycardia,[1] bradycardia or ventricular fibrillation.[2] In a normal heart beat rhythm, the SA node usually suppresses the ectopic pacemaker activity due to the higher impulse rate of the SA node. However, in the instance of either a malfunctioning SA node or an ectopic focus bearing an intrinsic rate superior to SA node rate, ectopic pacemaker activity may take over the natural heart rhythm.[3] This phenomenon (an intrinsically slower pacemaker activity being unmasked by failure of faster pacemaker tissue 'upstream') is called an escape rhythm, the lower rhythm having escaped from the dominance of the upper rhythm. As a rule, premature ectopic beats (i.e. with a shorter ...

... s (PACs), also known as atrial premature complexes (APC) or atrial premature beats (APB), are a common cardiac dysrhythmia characterized by premature heartbeats originating in the atria. While the sinoatrial node typically regulates the heartbeat during normal sinus rhythm, PACs occur when another region of the atria depolarizes before the sinoatrial node and thus triggers a premature heartbeat.[1] The exact cause of PACs is unclear; while several predisposing conditions exist, PACs commonly occur in healthy young and elderly people. Elderly people that get PACs usually don't need any further attention besides follow ups due to unclear evidence.[2][3] PACs are often completely asymptomatic and may be noted only with Holter monitoring, but occasionally they can be perceived as a skipped beat or a jolt in the chest. In most cases, no treatment other than reassurance is needed for PACs, although medications such as beta blockers can reduce the frequency of symptomatic ...
... (CAD), also known as ischemic heart disease (IHD),[13] refers to a group of diseases which includes stable angina, unstable angina, myocardial infarction, and sudden cardiac death.[14] It is within the group of cardiovascular diseases of which it is the most common type.[15] A common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck, or jaw.[4] Occasionally it may feel like heartburn. Usually symptoms occur with exercise or emotional stress, last less than a few minutes, and improve with rest.[4] Shortness of breath may also occur and sometimes no symptoms are present.[4] In many cases, the first sign is a heart attack.[5] Other complications include heart failure or an abnormal heartbeat.[5] Risk factors include high blood pressure, smoking, diabetes, lack of exercise, obesity, high blood cholesterol, poor diet, depression, and excessive alcohol.[6][7][16] The underlying mechanism involves reduction of blood flow and oxygen to the ...
