title: Percutaneous transluminal coronary angioplasty. Its success rate and affecting factors.
abstract: From December 1987 to October 1983, percutaneous transluminal coronary angioplasty (PTCA) was performed in 302 patients with 392 diseased vessels and 440 lesions. The success rate was 93.71% in 302 patients, 94.90% in 392 diseased vessels and 95.00% in 440 lesions. The success rate was 98.92% in Type A lesion, 95.71% in Type B lesion, and 86.57% in Type C lesion (A vs B P = NS, A vs C P < 0.01). There were 55 lesions with total or subtotal occlusion, the success rate was 89.09% (93.10% in Type B lesion and 84.62% in Type C lesion). As to the diseased vessels, the success rate was 95.65% in LAD, 94.38% in LCX and 93.75% in RCA. The results showed no significant difference. In this series, acute ischemic complications were found in 6.59% (29/440). Of these 29 lesions, 23 were treated successfully, 5 developed Q wave myocardial infarction and 1 died.
