Between October 1988-January 1991, PTCA procedure was performed in 505 patients (604 stenoses). The average age was 51±7 years. There were 436 men (% 86) and 69 women (% 14). Angiographically, 304 patients (% 60) had single-vessel disease, 145 patients (% 29) two-vessel disease and 56 patients (% 11) had three-vessel disease. Ejection fraction was higher than % 50 in 485 (% 96) patients. Procedural success was achieved in 444 patients (% 88). 530 stenoses (% 83.7) were dilated successfully. Stepwise regression analysis determined that modified ACC/AHA classification of the primary target stenosis and the presence of diabetes mellitus were the only variables independently predictive of procedural outcome (target stenosis modified ACC/AHA score p<0.0001 for success, diabetes mellitus p=0.004 for success). Success rates for type A, B1 B2 and C were 90.8 %, 89.6 %, 70.6 % and 55.6 % respectively. In conclusion, subdivision into types B1 and B2 provided significantly more information in this clinically important intermediate risk group than did the standard ACC/AHA scheme. The stenosis characteristics of bifurcation lesions, high-grade (% 80-99) stenosis, total occlusion and length of the lesions were inversely correlated with procedural success.
