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 ...
In 2015 cardiomyopathy and myocarditis affected 2.5 million people. [6] Hypertrophic cardiomyopathy affects about 1 in 500 people while dilated cardiomyopathy affects 1 in 2,500. [3] [10] They resulted in 354,000 deaths up from 294,000 in 1990. [7] [11] Arrhythmogenic right ventricular dysplasia is more common in young people. [2]
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 ...
The research, he said, could provide insight into developing treatments for vaccine-induced myocarditis. There are currently no drugs for the condition, though most people fully recover on their own.
Eosinophilic myocarditis is often viewed as a disorder that has three progressive stages. The first stage of eosinophilic myocarditis involves acute inflammation and cardiac cell necrosis (i.e. areas of dead cells); it is dominated by symptoms characterized as the acute coronary syndrome such as angina, heart attack and/or congestive heart failure.
It is an uncommon cause of unexplained heart failure in infants and children, and is one component of HEC syndrome. Fibroelastosis is strongly seen as a primary cause of restrictive cardiomyopathy in children, along with cardiac amyloidosis, which is more commonly seen in progressive multiple myeloma patients and the elderly.

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 ...
The CDC had previously said that reporting rates of myocarditis for boys aged 16 to 17 could be more than 69 cases per million second doses administered and around 40 cases per million second ...
