PTCA IN 100 PRIMARY CASES

Abstract

We performed percutaneous transluminal coronary angioplasty (PTCA) on 111 lesions in 100 patients from July 1988 through July 1989. We studied the primary success rate, complications, restenosis rate, improved myocardial function during treadmill testing and improvement in left ventricular ejection fraction (LVEF). The overall primary success rate was 82.9% (87.5% for LAD, 63.2% for LCX, 87.5% for RCA). Acute myocardial infarction occurred in one patient, who suffered cerebrovascular bleeding and died. The incidence of restenosis was 36.2% (25/69 lesions). Exercise capacity during treadmill testing was improved from 6.9±3.0mets to 9.0 ± 2.5mets after successful PTCA. LVEF was improved from 61.1 ± 12.4% to 65.5 ± 10.7% in patients without restenosis. The results of PTCA in 100 primary cases were favorable in comparison with those of other studies.
