LATE CORONARY ANGIOPLASTY AND VENTRICULAR LATE POTENTIALS

To assess the effect of successful late coronary angioplasty of an occ luded infarct-related artery on the prevalence of ventricular late pot entials, signal-averaged electrocardiograms were recorded in 123 conse cutive patients surviving a first acute myocardial infarction (58 with and 65 without mechanical reperfusion of the occluded coronary artery ). Multivariate analysis showed that successful reperfusion by late an giolasty of the infarct artery contributes to a decrease in the preval ence of late potentials.
