Statins and hypertension.

Hypertension and dyslipidemia are frequently associated as risk factors for cardiovascular diseases. Statins are among the most potent drugs to correct hypercholesterolemia, and their use across a wide range of cardiovascular risk levels significantly reduced morbidity and mortality in large intervention trials. Aside from (or in addition to) reducing plasma cholesterol, statins also reduce blood pressure, another effect associated with cardiovascular risk reduction by other antihypertensive drugs. This review examines the proposition that a part of the statins' beneficial effect in cardiovascular diseases may result from direct effects on blood pressure regulation, perhaps independent of lipid lowering. Potential molecular mechanisms are considered (e.g., "pleiotropic" effects on endothelial vasoactive mediators, oxidant stress, or inflammation), all of which may affect the central or peripheral control of blood pressure homeostasis, as well as modulate target organ damage. In particular, potential effects of statins on blood pressure and heart rate variability open new perspectives for a better tailoring of drug treatment in high-cardiovascular risk patients.
