Myocardial involvement has been described during previous SARS and MERS outbreaks. Infection by SARS-CoV-2 (COVID-19) can range from asymptomatic to life-threatening multi-system disease. Heart involvement most commonly occurs during severe COVID-19 infection. Myocardial injury, based on elevated levels of myocardial enzymes, has been noted in up to 30% of patients with COVID-19 infection and could be a marker for worse prognosis. A few cases of possible myocarditis due to SARS-CoV-2 have been described, providing variable degree of evidence of direct myocardial involvement. We reviewed in detail those cases in comparison to relevant literature on SARS and MERS and attempted to draw initial conclusions in regard to clinical presentation, treatment and prognosis.
