Myocardial infarction (MI) is one of the leading causes of death worldwide for men and women of all races. More than 800,000 MIs occur in the United States each year. Commonly referred to as "heart attack," MI is the irreversible death (necrosis) of heart muscle secondary to prolonged lack of oxygen supply (ischemia). MI usually results from an imbalance in oxygen supply and demand, which is most often caused by plaque rupture with thrombus formation in an epicardial coronary artery, resulting in an acute reduction of blood supply to a portion of the myocardium.
In response to the ongoing COVID-19 pandemic, the American College of Cardiology (ACC) released guidance regarding cardiac implications. Among the recommendations was a reminder to providers that classic symptoms and typical presentation of acute MI may be overshadowed in the context of COVID-19, leading to underdiagnosis.
