title: Coronary angiographic findings in patients with diabetes: an exercise in cardiovascular epidemiology.
abstract: A study of 516 patients with diabetes mellitus who presented with chest pain and an equal number of matched controls without diabetes examined by selective coronary arteriography was undertaken. Detailed analysis of the angiograms showed that prevalence of CAD in diabetics with symptoms was 86.6%. This prevalence increased with age. Multivessel disease was more common in diabetics that in controls (p < 0.01). In diabetic patients disease involvement of proximal and distal segments in the same vessel was more common (p < 0.01). The Gensini score of quantitative expression of severity of CAD was higher in diabetics (p < 0.05). The number of occluded segments in the coronary tree was higher in diabetics (p < 0.01). No correlation could be established between severity of disease and age, body mass index or duration of diabetes. It is concluded that diabetes affects the coronary arteries of Indian patients more adversely than those of non-diabetics. The prevalence of CAD among diabetics increases linearly with age.
