Larry A2 - Loscalzo, Joseph PY - 2014 T2 - Harrison's Principles of Internal Medicine, 19e AB - Patients with ischemic heart disease fall into two large groups: patients with chronic coronary artery disease (CAD) who most commonly present with stable angina (Chap. 293) and patients with acute coronary syndromes (ACSs). These include patients with acute myocardial infarction with ST-segment elevation (STEMI) on their presenting electrocardiogram (Chap. 295) and those with non-ST-segment elevation acute coronary syndrome (NSTE-ACS). The latter include patients with non-ST-segment elevation myocardial infarction (NSTEMI), who, by definition, have evidence of myocyte necrosis, and those with unstable angina (UA), who do not. The relative incidence of NSTEMI compared to STEMI appears to be increasing (Fig. 294-1). Every year in the United States, approximately 1.1 million patients are admitted to hospitals with NSTE-ACS as compared with ∼300,000 patients with acute STEMI. Women comprise more than one-third of patients with NSTE-ACS, but less than one-fourth of patients with STEMI.
