[Treatment of hypertension in type 2 diabetes mellitus--2002 update].
Arterial hypertension and diabetes are potent independent risk factors for cardiovascular, cerebral, renal and peripheral (atherosclerotic) vascular disease. The prevalence of hypertension in diabetic individuals is approximately twice that in the non-diabetic population. Diabetic individuals with hypertension have a greater risk of macrovascular and microvascular disease than normotensive diabetic individuals. Hypertension is a major contributor to morbidity and mortality in diabetes, and should be recognized and treated early. Type 2 diabetes and hypertension share certain risk factors such as overweight, visceral obesity, and possibly insulin resistance. Life-style modifications (weight reduction, exercise, limitation of daily alcohol intake, stop smoking) are the foundation of hypertension and diabetes management as the definitive treatment or adjunctive to pharmacological therapy. Additional pharmacological therapy should be initiated when life-style modifications are unsuccessful or hypertension is too severe at the time of diagnosis. All classes of antihypertensive drugs are effective in controlling blood pressure in diabetic patients. For single-agent therapy, ACE-inhibitors, angiotensin receptor blocker, beta-blockers, and diuretics can be recommended. Because of concerns about the lower effectiveness of calcium channel blockers in decreasing coronary events and heart failure and in reducing progression of renal disease in diabetes, it is recommended to use these agents as second-line drugs for patients who cannot tolerate the other preferred classes or who require additional agents to achieve the target blood pressure. The choice depends on the patients specific treatment indications since each of these drugs have potential advantages and disadvantages. In patients with microalbuminuria or clinical nephropathy, both ACE-inhibitors and angiotensin receptor blockers are considered first line therapy for the prevention of and progression of nephropathy. Since treatment is usually life-long, cost effectiveness should be included in treatment evaluation.
