[Results of percutaneous coronary angioplasty in patients with stable and unstable angina].

Percutaneous coronary angioplasty is very well known percutaneous revascularization procedure. Results of the percutaneous coronary angioplasty vary according to the stage of ischemic heart disease. The aim of our study was to evaluate and to compare the results of percutaneous coronary angioplasty in patients with stable and unstable angina. We analyzed data from 1148 patients in both groups. The extent of atherosclerosis was significantly higher in unstable angina group, however there was no significant difference in procedural as well in in-hospital outcomes between two groups. Success rate was 86% in unstable angina group and 83.3% in stable angina group. Major adverse cardiac events occurred in 1.48% patients with no difference in both groups. Left ventricular ejection fraction and end-diastolic diameter improved more in unstable angina group.
