Assessment of the influence of coronary rask factors on angiographic morphology of coronary stenoses

To evaluate the influence of three major coronary risk factors, hypercholesterolemia, hypertension and diabetes, on the morphology of coronary artery lesions, we compared the coronary angiographic findings among the following four groups. 1) Hypercholesterolemia (CHO＞240mg/dl) patients without hypertension and diabetes. (n＝39, HC) 2) Hypertensive patients without diabetes and hypercholoesterlemia.(n＝51, HT) 3) Diabetic patients without hyoertension and hypercholesterolemia (n＝24, DM) 4) Patients without these three risk factors. (n＝90, C) These patients were old myocardial infarction or effort angina with coronary stenotic lesions. The other risk factors were not significantly different. The severity of coronary srtery lesions was assessed by Gensini score, andcoronary lesions were morpho
