ST-Elevation Myocardial Infarction (STEMI) I. What every physician needs to know. ST-segment elevation myocardial infarction (formerly known as Q-wave myocardial infarction) is an acute coronary syndrome caused by myocardial ischemia which results clinically in angina (or its equivalent), ST segment elevations on electrocardiogram (EKG), and subsequent elevation of cardiac biomarkers indicating myocardial necrosis. Myocardial injury…
Non-ST elevation Myocardial Infarction or Non-STEMI I. What every physician needs to know. Non-ST-segment elevation myocardial infarction (formerly known as non-Q-wave myocardial infarction MI) is an acute coronary syndrome caused by myocardial ischemia which results clinically in angina (or its equivalent) elevation of cardiac biomarkers indicating myocardial necrosis and generally involves electrocardiogram (EKG) findings of…
