From October 1981 to May 1990, 7000 elective percutaneous transluminal coronary angioplasties (PTCA) were performed at the Kokura Memorial Hospital, of which 5064 were analyzed using our computer system. The primary success rate of PTCA was 85%, in 1 vessel disease 88%, in 2 vessel disease 85%, and in 3 vessel disease 79%. Complications of PTCA were as follows: myocardial infarction, 2.1%; emergency CABG, 0.5%; death, 0.6%. We analyzed predictive factors for in-hospital death or emergency CABG. Five significant factors are significantly related: cerebral vascular accident, chronic renal failure, jeopardized collateral, abrupt closure, and dilatation of the left anterior descending artery.
