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]
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 ...
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]
Myocarditis-myositis-myasthenia gravis overlap syndrome (IM3OS) is a rare immune-related adverse event primarily associated with the use of immune checkpoint inhibitors (ICIs). These ICIs, which have been incorporated into the treatment of various malignancies , function by activating the immune system to detect and attack cancer cells .
The claim: Study shows myocarditis and pericarditis only appear after COVID-19 vaccination, not after COVID-19 infection. A June 24 Facebook post (direct link, archive link) shows an image of ...
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 ...
