Remodeling of the vascular tree in hypertension: drug effects.
The primary aim of current antihypertensive therapy is to lower blood pressure through the reduction of peripheral vascular resistance. Resistance reduction is achieved primarily by interference with acutely acting pressor stimuli. However, recent research has stressed the importance of slow pressor stimuli, which act by gradually remodeling the vascular tree. Long-term remodeling is achieved by a chronic change in vessel number, vascular diameter or wall thickness, involving both physical and chemical factors. The chemical mediators belong to a group of endogenous growth-affecting factors. As Harry Struyker Boudier and colleagues explain in this review, although there are thus far no specific drugs to antagonize the effects of these factors, several therapeutically used antihypertensives influence their action. Moreover, the concept that vascular remodeling is important in hypertension offers exciting new therapeutic targets.
