title: Beta-blockers, angiotensin-converting enzyme inhibitors, and calcium antagonists in treatment of elderly patients with acute myocardial infarction.
abstract: Administration of beta-blockers reduces mortality among old persons during and after acute myocardial infarction. The American College of Cardiology/American Heart Association guidelines recommend that persons without contraindications to use of beta-blockers should be administered beta-blockers within a few days of myocardial infarction (if administration is not initiated acutely) and that their administration should be continued indefinitely. These guidelines also recommend the use of angiotensin converting enzyme inhibitors in treating persons within the first 24 h of suspected onset of acute myocardial infarction with ST-segment elevation in two or more anterior precordial leads or with congestive heart failure in the absence of significant hypotension or other contraindications to use of ACE inhibitors; and persons during and after convalescence from acute myocardial infarction with congestive heart failure associated with an abnormal left ventricular ejection fraction (LVEF) or with asymptomatic left ventricular systolic dysfunction with a LVEF < 40%. These guidelines state that there are no class I indications for using calcium antagonists after myocardial infarction. If patients have persistent angina pectoris after myocardial infarction despite treatment with beta-blockers and nitrates or hypertension inadequately controlled by other drugs, administration of a nondihydropyridine calcium antagonist such as verapamil or diltiazem should be added to the therapeutic regimen if the LVEF is normal. If the LVEF is abnormal, administration of amlodipine or felodipine should be added to the therapeutic regimen.
