Severe acute respiratory syndrome coronavirus-2 can affect the cardiovascular system yielding a wide range of complications, including acute myocardial injury. The myocardium can be damaged by direct viral invasion or indirect mechanisms, sustained by systemic inflammation, immune-mediated response, and dysregulation of the renin-angiotensin system. Myocardial injury affects about one-quarter of patients with COVID-19, can manifest even in the absence of previous cardiovascular disease, and is associated to higher mortality rates and long-term sequelae. This review describes the pathophysiological mechanisms of myocardial injury and infarction and discusses the main clinical outcomes and diagnostic challenges associated with myocardial damage during COVID-19.
Keywords: COVID-19; Myocardial infarction; Myocardial injury; SARS-CoV-2.
