Telmisartan and cardioprotection

Abstract

Cardiovascular risk reduction has been the target of several large clinical trials in the last decade. As the activation of the renin-angiotensin-aldosterone system (RAAS) plays a central role in the pathogenesis of atherosclerosis and cardiovascular disease, RAAS blockade has been suggested to be among the most efficient cardioprotective interventions, as revealed with the angiotensin converting enzyme (ACE) inhibitors trials. The angiotensin receptor blockers' (ARBs) efficacy in lowering blood pressure has been very well established. Telmisartan is however the first ARB to show a promising role in reducing cardiovascular risk in high-risk patients. This article will highlight the role of telmisartan in cardioprotection, underlying specifically the results of two major randomized controlled trials: ONTARGET (ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial) and TRANSCEND (Telmisartan Randomized AssessmeNt Study in aCE-iNtolerant subjects with cardiovascular Disease). © 2011 Akhrass and McFarlane, publisher and licensee Dove Medical Press Ltd.
