Abstract
In order to evaluate the relationship between frequency of restenosis after percutaneous transluminal coronary angioplasty (PTCA) and glycemic control in patients with NIDDM, we assessed 86 NIDDM with stable angina pectoris who underwent elective and successful PTCA after excluding those with familial hypercholesterolemia, renal failure, unstable angina or coronary artery bypass graft surgery within 1 month previousty, between 1983 and 1991. Blood pressure, body mass index, history of smoking, fasting blood glucose, HbA1c, total cholesterol, triglyceride, number of stenotic vessels, and restenosis rate were assessed. The frequency of restenosis within one year after PTCA was significantly greater a poorly controlled NIDDM than in well or fairly well controlled NIDDM. Multivariate analysis showed that the degree of diabetic control was significantly correlated with restenosis. These findings indicate that diabetic control plays an important role in restenosis after PTCA.
