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 .
Fulminant myocarditis is defined as sudden and severe myocarditis that is associated with signs and symptoms of heart failure while at rest. [15] More specifically, fulminant myocarditis is characterized by a distinct, rapid onset of severe heart failure symptoms, such as shortness of breath and chest pain, that develop over the course of hours ...
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 ...
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.
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]
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.
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 ...
Duke treadmill scores typically range from –25 (highest risk) to +15 (lowest risk). One-year mortality and five-year survival rates respectively for the results of the Duke treadmill score have been reported as follows: [4] [5] [6] less than or equal to –11: 5.25%, 65% –10 to 4: 1.25%, 90% greater than or equal to 5: 0.25%, 97%
