How far should blood pressure be reduced in diabetic hypertensive patients?

EPIDEMIOLOGY OF DIABETES

Diabetes mellitus and arterial hypertension are closely related diseases that strongly predispose an individual to atherosclerotic cardiovascular disease and to renal failure. High blood pressure is twice as frequent in diabetics compared with the general population, and often precedes and contributes to the development of diabetic nephropathy. The prevalence of coexisting arterial hypertension and non-insulin-dependent diabetes mellitus (NIDDM) is increasing as populations age, giving an increased prevalence of both diseases. TREATMENT OF HYPERTENSIVE DIABETIC PATIENTS: The goal of treating arterial hypertension in diabetic patients is to prevent death and disability associated with high blood pressure. In addition, other reversible risk factors for cardiovascular disease, seen so frequently in hypertensive diabetics, also need to be addressed. The optimal goal of blood pressure control in diabetics has not been established, but there are indications that it should be lower than the 130/85 mmHg systolic/diastolic pressure recommended by current guidelines. In the presence of multiple associated risk factors, most guidelines suggest a threshold for intervention of > or = 140/90 mmHg. In particular, in hypertensive diabetic patients intervention must be early and aggressive.
