ABSTRACT
The aim of this study was to estimate the incidence of the major adverse cardiac events [MACE] in patients undergoing percutaneous transluminal coronary angioplasty [PTCA] and detect the possible predictors of these events. The study included 11 patients underwent PTCA. Seventy-three patients were presented with unstable angina, 37 patients with stable angina and one patient had post-infarction angina. MACE included death, myocardial infarction and emergency bypass surgery during or within 24 hours of the procedure. A procedural success was achieved in 80.2% of the patients. Failed PTCA occurred in 11.7% of the patients. MACE occurred in nine patients. Three patients died, four developed myocardial infarction and two patients were referred for emergency bypass surgery. MACE occurred in 12.3% of the patients with unstable angina versus 0.0% of those with stable angina. The lesion class was the best predictor of MACE in this study by univariate analysis. Balloon to artery ratio in patients with and without MACE was 1.36 +/- 0.52 and 1.01 +/- 0.18
