This study evaluated the relation between patency of the infarct related artery and the presence of ventricular late potentials (VLP) on the signal-averaged electrocardiogram (ECG). 44 patients (pts) after myocardial infarction (MI) (35 men, 9 women; mean age 50 years) were studied by coronary angiography. measurement of ejection fraction and signal-averaged ECG. The infarct-related artery was closed in 15 pts and open in 29 pts. There was no difference in age, previous MI and location of infarct between the two study groups. Thrombolytic therapy in acute stage of MI was significantly often (p less than 0.05) in pts with open (59%) than closed (13%). The incidence of VLP was significantly higher (p less than 0.05) in group of pts with closed (40%) than open artery (7%). These data indicate that patency of the infarct-related artery has a beneficial effect on the electrophysiologic substrate for serious ventricular arrhythmias.
