title: CHD: a major burden in type 2 diabetes.
abstract: Patients with type 2 diabetes have a two- to four-fold greater risk of cardiovascular mortality than non-diabetic individuals. In order to prevent coronary events in the diabetic population, it is important to treat modifiable cardiovascular risk factors. Data from the Multiple Risk Factor Intervention Trial (MRFIT) show that serum cholesterol level, systolic blood pressure level and cigarette smoking were significant predictors of cardiovascular disease mortality in men with and without diabetes. At every risk factor level, the absolute risk of age-adjusted coronary death rate was three times greater for diabetic men than non-diabetic men (p<0.0001). Patients with diabetes have an abnormal (dyslipidaemic) lipoprotein profile with high levels of very low density lipoprotein cholesterol and triglycerides, and a low level of high density lipoprotein cholesterol. Although levels of total cholesterol or low density lipoprotein (LDL) cholesterol do not differ significantly between patients with and without diabetes, those with diabetes have higher levels of atherogenic small dense LDL particles. MRFIT data show that at any serum cholesterol level, diabetes confers two-three times the risk for a coronary event. These findings constitute the rationale for considering hypolipaemic therapy, e.g. with HMG-CoA reductase inhibitors (statins), in diabetic patients with dyslipidaemia, particularly in those with evidence of coronary heart disease. Evidence shows that statins significantly lower cholesterol, exhibit beneficial effects on many components of atherosclerosis, and can significantly reduce the incidence of stroke.
