Abstract

In the present study we evaluated the influence of intravenous thrombolysis and patency of the infarct-related coronary artery on both markers of ventricular electrical instability and incidence of late arrhythmic events after acute myocardial infarction (AMI). Ninety one patients surviving a first AMI who consecutively performed coronary angiography were enrolled in the present study; 44 patients (48%) received thrombolysis, 47 patients (52%) were treated conventionally. Of 91 patients, 90 (99%) had signal-averaged electrocardiogram (SAECG), and 40 (44%) programmed ventricular stimulation. No significant difference was observed between thrombolytic-treated and control group in late potential rate, SAECG determinants and ventricular arrhythmia inducibility. Of 91 patients, 40 (44%) had occlusion of the infarct-related artery: of these, 15 (37%) had late potentials compared with 5 of 51 patients (9%) with a patent artery (p <0.01). Mean left ventricular ejection fraction was not significantly different between the two groups (0.50 +/- 0.15 vs 0.55 +/- 0.12; p = NS). No significant difference was present between the two groups of patients with regard to inducibility of sustained ventricular tachyarrhythmias, however an odds ratio of 3.5 was observed in the group with a closed vessel.(ABSTRACT TRUNCATED AT 250 WORDS)
