Learn about the causes, symptoms, diagnosis, treatment, and prevention of acute coronary syndromes, which include heart attack (myocardial infarction). Find out how a blood clot, a spasm, or a ruptured plaque can block a coronary artery and affect the heart muscle.
Myocardial infarction is defined as myocardial necrosis in a clinical setting consistent with myocardial ischemia (1). These conditions can be satisfied by a rise of cardiac biomarkers (preferably cardiac troponin [cTn]) above the 99th percentile of the upper reference limit (URL) plus at least one of the following: Symptoms of ischemia.
