Abstract

We analyzed 69 consecutive PTCA performed upon 64 patients from January 1990 to May 1992. Age was 55 +/- 12 years and 80% were male. Fifty-nine percent were smokers, 32% had hypertension, 16% a remote myocardial infarction, 14% diabetes, 12% previous PTCA, and 6% previous coronary artery bypass surgery. Total cholesterol was 238 +/- 75 mg/dl. Most of the subjects had an acute coronary syndrome, with unstable angina in 31 and a recent myocardial infarction in 23. Angiographically, 52% had single vessel disease, 39% had double vessel and 9% triple vessel disease. LVEF was 55 +/- 11%, LVEDP 17 +/- 10 mm Hg, and 44% had wall motion abnormalities. We dilated 1.4 lesions/patient (1-4), for a total of 100 lesions. Luminal stenosis was reduced from (mean +/- SEM) 88.5 +/- 1.1% to 22.6 +/- 2.2% (p < 0.0001). The procedure was a total clinical success in 85.6% of the patients and a partial clinical success in 4.3%. Complete revascularization was achieved in 62.3% and incomplete but adequate revascularization in 26%. Multiple lesions dilatation was performed in 30% of the patients and multiple vessel angioplasty in 17%. Forty-seven lesions were on the LAD distribution (91.5% angiographic success), 24 on the circumflex (95.8% angiographic success), 26% on RCA (88.4% angiographic success) and 3 in others. There was a 10% failure and 13% complication rates, but more than half of them were successfully managed medically, although 5.7% required urgent CABG. One patient died.
