Viral myocarditis being an outcome of viral infection depends heavily on genetic host factors and the pathogenicity unique to the virus. [56] If one tests positive for an acute viral infection, clinical developments have discovered that 1-5% of said population may show some form of myocarditis.
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 ...
Pericarditis may be caused by viral, bacterial, or fungal infection. In the developing world the bacterial disease tuberculosis is a common cause, whereas in the developed world viruses are believed to be the cause of about 85% of cases. [6] Viral causes include coxsackievirus, herpesvirus, mumps virus, and HIV among others. [4]
The coronavirus can damage the heart, according to a major new study which found abnormalities in the heart function of more than half of patients.
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.
Coxsackie B infections usually do not cause serious disease, although for newborns in the first 1–2 weeks of life, Coxsackie B infections can easily be fatal. [2] The pancreas is a frequent target, which can cause pancreatitis. [2] Coxsackie B3 (CB3) infections are the most common enterovirus cause of myocarditis and sudden cardiac death. [8]
The cause is typically a bacterial infection and less commonly a fungal infection. [1] Risk factors include valvular heart disease, including rheumatic disease, congenital heart disease, artificial valves, hemodialysis, intravenous drug use, and electronic pacemakers. [6] [7] [5] The bacteria most commonly involved are streptococci or ...
I got my first COVID infection in January 2020, before most people even realized the coronavirus was here. I was a third-year medical student, and I saw a patient who had just returned from Japan ...
