Insights
Chronic activation of the renin-angiotensin-aldosterone system (RAAS) significantly impacts cardiometabolic risk and kidney function. RAAS inhibition therapies are crucial for managing cardiovascular disease and renal dysfunction.
Area of Science:
- Cardiovascular Medicine
- Nephrology
- Endocrinology
Background:
- Chronic activation of the renin-angiotensin-aldosterone system (RAAS) contributes to cardiovascular disease, renal dysfunction, and cardiometabolic risk.
- Sustained RAAS activation leads to vascular issues like fibrosis, endothelial dysfunction, and cellular remodeling.
Purpose of the Study:
- To provide a historical overview of the evolution of RAAS inhibitors.
- To discuss the established role and expanding treatment landscape of RAAS inhibition.
- To explore recently discovered functions of RAAS components.
Main Methods:
- Review of historical data and clinical practice of RAAS inhibition therapies.
- Analysis of the mechanisms of action for ACE inhibitors, ARBs, and direct renin inhibitors.
- Discussion of current understanding and future directions in RAAS modulation.
Main Results:
- RAAS inhibition therapies have been clinically used for over 30 years.
- These therapies are essential for reducing the risk of cardiovascular and renal diseases.
- Understanding of RAAS inhibition has expanded treatment options.
Conclusions:
- RAAS inhibition is a cornerstone in managing cardiovascular and renal diseases.
- Continued research into RAAS components reveals new therapeutic targets.
- RAAS inhibitors play a vital role in mitigating cardiometabolic risk and preventing organ damage.
Abstract:
Chronic renin-angiotensin-aldosterone system (RAAS) activation has far-reaching effects on cardiometabolic risk and is a substantial contributor to cardiovascular (CV) disease and renal dysfunction. The vascular effects of sustained RAAS activation are associated with hemodynamic imbalances, as well as inflammatory stimulation and prothrombotic processes that lead to fibrosis, endothelial dysfunction and cellular remodeling. RAAS inhibition therapies, which include the use of angiotensin-converting enzyme inhibitors, angiotensin receptor blockers and more recently, direct renin inhibitors, have been used in clinical practice for more than 30 years. Our understanding of how these drugs work, alone and in combination, has contributed to an expanding landscape of treatment options and established RAAS inhibition as essential for reducing the risk of CV and renal disease. This perspective provides a historical overview of how RAAS inhibitors have evolved to their present-day status and will discuss recently discovered functions for components of this complicated and powerful regulatory system.
