Viral-induced dilated cardiomyopathy can be characterized using different methods. A 2011 study showed in coxsackievirus infected heart proteome , increased levels of fibrotic extracellular matrix proteins and reduced amounts of energy-producing enzymes can be observed suggesting they could be characteristic in enteroviral cardiomyopathy.
Viral cardiomyopathy occurs when viral infections cause myocarditis with a resulting thickening of the myocardium and dilation of the ventricles. These viruses include Coxsackie B and adenovirus, echoviruses, influenza H1N1, Epstein–Barr virus, rubella (German measles virus), varicella (chickenpox virus), mumps, measles, parvoviruses, yellow fever, dengue fever, polio, rabies, and the ...
Myocarditis is defined as inflammation of the myocardium. Myocarditis can progress to inflammatory cardiomyopathy when there are associated ventricular remodeling and cardiac dysfunction due to chronic inflammation. [6] [7] Symptoms can include shortness of breath, chest pain, decreased ability to exercise, and an irregular heartbeat. [1]
Treatment depends on the type of cardiomyopathy and the severity of symptoms. [5] Treatments may include lifestyle changes, medications, or surgery. [5] Surgery may include a ventricular assist device or heart transplant. [5] In 2015 cardiomyopathy and myocarditis affected 2.5 million people. [6]
Covalently bonded to the 5’ UTR is the viral protein VPg which aids in viral entry and replication. 2A and 3C are viral proteinases which aid in the cleavage of the polyprotein encoded for by the genome. 3D is the RNA-dependent RNA polymerase (RdRP). 2B, 2C, and 3A are core viral proteins.
Strictly considering myocarditis risk and ignoring the other severe problems from COVID-19, people under 25 years old are 7 to 37 times more likely to get myocarditis from infection with COVID-19 ...
Or, it may be the late sequelae of acute viral myocarditis, such as with Coxsackie B virus and other enteroviruses [14] possibly mediated through an immunologic mechanism. [15] Specific autoantibodies are detectable in some cases. [16] Other causes include: Chagas disease, due to Trypanosoma cruzi.
Treatment antiarrythmic agents , diuretics , catheter ablation , pacemaker [ 1 ] Tachycardia-induced cardiomyopathy (TIC) is a disease where prolonged tachycardia (a fast heart rate) or arrhythmia (an irregular heart rhythm) causes an impairment of the myocardium (heart muscle), which can result in heart failure .
