Management After Myocardial Infarction.

Individuals who survive an acute myocardial infarction (MI) have up to a ninefold greater risk of cardiovascular morbidity and mortality compared with the general population. The modification of traditional coronary risk factors, including hypertension, hyperlipidemia, tobacco use, and diabetes mellitus, constitutes one of the cornerstones of management after acute MI. Therapies aimed at reversing the pathophysiologic disorders that lead to endothelial dysfunction, thrombosis, and atherosclerotic plaque instability may improve the prognosis for patients after acute MI. Aggressive risk stratification diagnostic testing can identify patients at the highest risk for adverse events. Prior to hospital discharge, patients should have an evaluation of left ventricular systolic function, an assessment for the risk for residual myocardial ischemia, and a clinical assessment of the risk for serious ventricular arrhythmias. An array of pharmaceutical agents is available for the secondary prevention of MI, including antiplatelet agents, beta-blockers, angiotensin-converting enzyme inhibitors, and statins.
