title: Acute myocardial infarction: state of the art.
abstract: The proper management of patients with acute myocardial infarction changes frequently as new data develop in this complex area. The present recommendations concerning the use of oxygen and morphine and the treatment of hypotension and congestive heart failure require little change save the addition of new agents. However, considerable new data have been derived in the area of limitation of myocardial infarct size. Several studies suggest that the early administration of beta-blockers or intravenous nitroglycerin may benefit patients with acute infarction. We must seriously consider whether the data supporting the use of these agents justify a recommendation that they be used routinely for patients with acute infarction. The role of thrombolytic agents, although widely used already, must also be addressed as data supporting its use build. Additionally, there are suggestive data that the aggressive treatment of hypertension is beneficial, and this approach may well merit advocacy. The prophylactic use of lidocaine and the ubiquitous use of nitrates necessitate reevaluation, although presently both agents are widely used. The aggressive use of electrical therapy for supraventricular arrhythmias and the lack of indication for the treatment of asymptomatic bradycardia with atropine in patients with acute infarction must be added to the previous National Conference standards.
