title: Cardiovascular structural changes in hypertension: possible regression during long-term antihypertensive treatment.
abstract: Arterial hypertension is often complicated by left ventricular hypertrophy (LVH) and by vascular structural changes resulting in decreased proximal and distal compliance. LVH is an adverse prognostic factor because it increases the incidence of sudden death and other morbid events related to ischaemic heart disease, whereas vascular alterations may induce target organ damage and contribute to the maintenance of elevated blood pressure values. Thus, antihypertensive treatment must both reduce blood pressure and halt regression of cardiovascular structural changes. A review of the literature suggests long-term use of calcium antagonists, ACE inhibitors, and beta-blockers may revert LVH. We have found that such long-term drug use not only reduces blood pressure and LVH, but also ventricular arrhythmias that are often related to cardiac hypertrophy; however, diuretics do not have this beneficial effect. As regards vascular disturbances ACE inhibitors partially revert these alterations, whereas beta-blockers do not. Further studies are needed to determine whether there are regional differences in the regression of cardiovascular structural changes or whether different antihypertensive drugs have different effects on these changes.
