Mortality from acute myocardial infarction has declined in recent years, largely due to the widespread application of new pharmacologic and mechanical interventions that have been tested in large, prospective, randomized clinical trials. For practicing generalists, we review the key data from such trials that have shaped the current management of patients with acute myocardial infarction. We discuss the roles of thrombolytic therapy, coronary angioplasty, nitrates, beta- and calcium channel blockers, angiotensin-converting-enzyme inhibitors, magnesium, and antiarrhythmic and antithrombotic agents. In addition, we highlight critical unanswered questions in the management of this disorder.
