Hypertension and macrovascular disease--the killing fields of NIDDM.

Diabetes mellitus and particularly non-insulin-dependent diabetes mellitus (NIDDM) increases the risk for all manifestations of: (a) atherosclerotic vascular disease; (b) coronary heart disease (CHD); (c) cerebrovascular disease; and (d) peripheral vascular disease. NIDDM is known to be associated with several adverse cardiovascular risk factors, including: (i) hypertension; (ii) obesity; (iii) central obesity; (iv) hyperinsulinemia; and (v) serum lipid and lipoprotein abnormalities, characterized mainly by elevated serum total triglycerides and low high-density lipoprotein cholesterol. This review will discuss the prevalence of hypertension in NIDDM, the role of hypertension to increase the risk for macrovascular complications in NIDDM and finally trial evidence for the beneficial effect of blood pressure lowering in patients with NIDDM.
