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 inflammation of the cardiac muscle. Myocarditis can progress to inflammatory cardiomyopathy when there is 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]
Cardiomyopathy is a group of primary diseases of the heart muscle. [1] Early on there may be few or no symptoms. [1] As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. [1]
There have been more than 1,200 cases of a myocarditis or pericarditis mostly in people 30 and under who received Pfizer’s or Moderna’s COVID-19 vaccine, according to CDC data.
Coxsackie-induced cardiomyopathy is a potential result of virally induced myocarditis. This cardiomyopathy may present with symptoms such as chest pain, fatigue, heart failure, cardiogenic shock, arrhythmias or sudden death. [7] These symptoms are a by-product of sustained cardiac muscle damage.

[32] [33] HAART has reduced the incidence of myocarditis thus reducing the prevalence of HIV-associated cardiomyopathy by about 30% in developed countries. [ 34 ] [ 35 ] However, the prevalence in developing countries is 32% and increasing as HAART is scarce – not to mention the effects of other risk factors such as high cholesterol and lipid ...
The prognosis of eosinophilic myocarditis is anywhere from rapidly fatal to extremely chronic or non-fatal. Progression at a moderate rate over many months to years is the most common prognosis. [ 1 ] [ 9 ] In addition to the speed of inflammation-based heart muscle injury, the prognosis of eosinophilic myocarditis may be dominated by that of ...
