Acute myocardial infarction with or without ST-segment eleva- tion (STEMI or non-STEMI) is a common cardiac emergency, with the poten- tial for substantial morbidity and mortality. The management of acute myo- cardial infarction has improved dramatically over the past three decades and continues to evolve. This review focuses on the initial presentation and in-hospital management of type 1 acute myocardial infarction. Acute myocardial infarction is an event of myocardial necrosis caused by an unstable ischemic syndrome.1 In practice, the disorder is diagnosed and assessed on the basis of clinical evaluation, the electrocardiogram (ECG), biochemical testing, invasive and noninvasive imaging, and pathological evaluation. Acute myocardial infarction is classified on the basis of the presence or absence of ST-segment elevation on the ECG and is further classified into six types: infarc- tion due to coronary atherothrombosis (type 1), infarction due to a supply–demand mismatch that is n...
