Abstract

In survivors of acute myocardial infarction, the restoration of antegrade flow in the infarct-related coronary artery may improve prognosis by a mechanism independent of its effect on left ventricular function. Survival may be enhanced even when restoration of flow is accomplished days or weeks after the acute event. In a series of retrospective studies of survivors of a first myocardial infarction, it was shown that long-term survival is significantly better in those with than in those without antegrade flow in the infarct-related artery. It is hypothesized that late restoration of antegrade flow in the infarct-related artery renders the border zone of the infarction more electrically stable, thereby diminishing the incidence of ventricular tachyarrhythmias and sudden death.
