Insights
Telmisartan, an angiotensin receptor blocker (ARB), shows promise in reducing cardiovascular risk. Clinical trials like ONTARGET and TRANSCEND evaluated its cardioprotective effects in high-risk patients.
Area of Science:
- Cardiology
- Pharmacology
- Internal Medicine
Background:
- The renin-angiotensin-aldosterone system (RAAS) is implicated in atherosclerosis and cardiovascular disease (CVD) pathogenesis.
- RAAS blockade, particularly with angiotensin converting enzyme (ACE) inhibitors, is a recognized cardioprotective strategy.
- Angiotensin receptor blockers (ARBs) effectively lower blood pressure, but their role in CVD risk reduction is under investigation.
Purpose of the Study:
- To highlight the cardioprotective role of telmisartan, an ARB.
- To review the findings of the ONTARGET and TRANSCEND randomized controlled trials regarding telmisartan's efficacy.
Main Methods:
- Review of two major randomized controlled trials: ONTARGET and TRANSCEND.
- Evaluation of telmisartan's effects on cardiovascular endpoints in high-risk patient populations.
- Comparison of telmisartan alone versus in combination with ramipril (ONTARGET) and telmisartan in ACE inhibitor-intolerant patients (TRANSCEND).
Main Results:
- Telmisartan demonstrated a promising role in reducing cardiovascular risk in high-risk individuals.
- ONTARGET trial results provided insights into telmisartan's efficacy and safety profile.
- TRANSCEND study assessed telmisartan's benefits in patients intolerant to ACE inhibitors.
Conclusions:
- Telmisartan emerges as a significant therapeutic option for cardiovascular risk reduction.
- The findings support the use of telmisartan in managing high-risk cardiovascular patients.
- Further research may elucidate the full potential of telmisartan in 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).
