The relationship of cardiovascular risk factors to the prevalence of coronary heart disease in newly diagnosed type 2 (non-insulin-dependent) diabetes.

The relationship of cardiovascular risk factors to the prevalence of coronary heart disease was examined in 133 newly diagnosed Type 2 (non-insulin-dependent) diabetic patients (70 men, 63 women) aged from 45 to 64 years and in 144 randomly selected non-diabetic control subjects (62 men, 82 women) of the same age. The prevalence of coronary heart disease in diabetic patients, defined by symptoms and ischaemic ECG abnormalities in resting or exercise ECG, was more than threefold that in non-diabetic subjects. In multiple logistic analyses (including age, history of smoking, hypertension (+/-), serum cholesterol, HDL-cholesterol, triglycerides, 2-h post-glucose serum insulin, body mass index and diabetes (+/-] carried out separately for men and women, diabetes showed an independent, significant association to coronary heart disease in both sexes. In addition, age and hypertension had a borderline association to coronary heart disease in men, whereas smoking and high 2-h post-glucose serum insulin level showed a significant association in women.
