Antihypertensive Therapies and Left Ventricular Hypertrophy.

Abstract

It is widely accepted that successful lowering of blood pressure (BP) in patients with hypertension leads to regression of left ventricular hypertrophy (LVH). However, whether differences exist among pharmacological BP-lowering therapies is debated. In this report, we discuss these differences in light of recent literature and the position of extant practice guidelines. Studies comparing the effects of antihypertensive classes on LVH regression reached different conclusions, but the overall direction which is reflected in current society guidelines is that successful lowering of BP is more important than selection of an individual antihypertensive class. Nevertheless, some practice guidelines added statements about considering a specific antihypertensive class for its potential benefit such as angiotensin-converting enzyme inhibitors and/or excluding a class such as direct vasodilators. On the other hand, reports have been consistent about the more favorable effect of intensive BP-lowering strategy (target systolic BP <120mmHg) compared to standard BP lowering (target systolic BP >140mmHg), which is not yet discussed in the current practice guidelines. Successful lowering of BP leads to LVH regression. While reports have been inconsistent about differences among antihypertensive classes, lowering BP beyond currently recommended levels has consistently showed a greater effect on LVH regression.
