Angiographic study of coronary artery disease in diabetic patients in comparison with nondiabetic patients.

Diabetes mellitus is known to be a major risk factor for the development of coronary artery disease (CAD). The aim of this study was to investigate angiographically the coronary arteries of diabetic persons, focusing on the type and distribution of CAD, sex differences in CAD anatomy, and the size of the coronary vessels. This was a randomized study and included two groups of patients with angiographically demonstrated CAD.

Comparison of coronary collateral circulation in diabetic and nondiabetic patients suffering from coronary artery disease.

Background And Hypothesis: Although it is well established that diabetes mellitus (DM) induces more severe coronary artery disease (CAD), it is not known whether it contributes to the development of coronary collateral circulation. The present study examines coronary collateral circulation in diabetic and nondiabetic patients with angiographically verified CAD.

Methods: The study group consisted of 463 diabetic patients (382 men, 81 women) with a mean age of 60.

Comparison of angiographic findings, risk factors, and long term follow-up between young and old patients with a history of myocardial infarction.

We compared the angiographic findings, coronary risk factors and five years prognosis in 200 patients < or =45, and 260 patients >45 years old who where admitted with an acute myocardial infarction. We found that family history and smoking were the most common risk factors in patients < or =45 years old P<0.04, P<0.

Coronary-subclavian steal syndrome. Report of a case treated with subclavian angioplasty.

We describe the case of a man aged 42 who, five years before, had undergone aortocoronary bypass surgery using the internal mammary artery for the anterior and saphenous vein graft for the posterior descending arteries. Over the last one and a half years he had started to present angina pectoris as well as symptoms of vertebrobasilar insufficiency during exertion of the left upper extremity (recently during simple writing), whereas a full treadmill test was normal. Clinically, obstruction of the left subclavian artery was suspected with both coronary and subclavian steals.

Systolic segmental disappearance of internal mammary artery graft. Correlation with prolonged spasm of the graft.

Vasospasm of the saphenous vein and internal mammary grafts may develop spontaneously under several conditions. We present for the first time spasm of a left internal mammary artery bypass graft during coronary arteriography. A patient who underwent coronary artery bypass operation 4 years ago was recatheterized because he developed chest pain.
