Late coronary angioplasty and ventricular late potentials.
To assess the effect of successful late coronary angioplasty of an occluded infarct-related artery on the prevalence of ventricular late potentials, signal-averaged electrocardiograms were recorded in 123 consecutive 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 angioplasty of the infarct artery contributes to a decrease in the prevalence of late potentials.
