Effects of antihypertensive therapy on hypertensive vascular disease

Abstract

Hypertension is associated with alterations in the structure, function, and mechanical properties of large and small arteries. Changes in the endothelium, smooth muscle cell, extracellular matrix, and possibly the adventitia, contribute to complications of hypertension. In large arteries, vascular hypertrophy is found, often with increased stiffness of media components. In small arteries, particularly in mild hypertension, rearrangement of smooth muscle cells around a smaller lumen without changes in media volume (eutrophic remodeling) occurs; in more severe hypertension, hypertrophic remodeling with increased vascular stiffness can be found. Vascular remodeling is accompanied by an increase in the extracellular matrix, particularly collagen deposition. Recent studies have demonstrated that vascular remodeling and endothelial dysfunction of small and large vessels may be normalized by treatment with some antihypertensive agents (angiotensin converting enzyme inhibitors, angiotensin AT1 receptor antagonists, and long-acting calcium channel blockers). Angiotensin converting enzyme inhibitors have now been shown to improve outcomes in hypertensive patients, an effect that may in part be related to the vascular protective effects reviewed here.

This important 10-year study of diabetic patients suggests that ACE inhibition and b-blockade are equally effective in the treatment of patients with diabetes and hypertension.

Lancet 1999, 353:611–616. This randomized clinical trial showed equivalent effects of ACE inhibitors and conventional therapy, although the former were more effective on myocardial ischemic events and the latter on stroke. This effect on stroke may be the consequence of a randomization problem characterized by lower blood pressure in the conventional therapy group throughout the study.

Lancet 1999, 354:1751–1756. This important randomized clinical trial showed that ACE inhibitors are particularly effective at reducing the incidence of acute coronary events in an elderly hypertensive population; this effect may result in part from the vascular protection offered by these agents.

N Engl J Med 2000, 342:145–154. This extremely important study showed that the ACE inhibitor ramipril had a dramatic favorable effect on cardiovascular morbidity and mortality in a 4.5-year multicenter study. This effect may in part be the result of the vascular protective effect of interruption of the renin-angiotensin system.

Clin Exp Hypertens 1999, 21:553–562. This important retrospective study demonstrated that mortality has been reduced in this hypertension clinic since introduction of calcium channel antagonists and ACE inhibitors, and that this reduction appears mostly related to use of the latter.
