Insights
Angiotensin-receptor blockers (ARBs) effectively treat hypertension and offer cardiovascular benefits. These agents provide vascular and antiatherosclerotic effects, enhancing protection for at-risk patients.
Area of Science:
- Pharmacology
- Cardiovascular Medicine
- Nephrology
Background:
- The renin-angiotensin system significantly impacts circulatory homeostasis.
- Angiotensin II contributes to the pathophysiology of atherosclerosis, diabetes, and hypertension.
- Angiotensin-receptor blockers (ARBs) represent a recent class of antihypertensive medications.
Purpose of the Study:
- To review the antihypertensive effects of ARBs.
- To examine the cardiovascular benefits of ARBs.
- To explore the pleiotropic effects of ARBs.
Main Methods:
- Review of evidence-based medicine.
- Inclusion of well-controlled studies with mortality and morbidity endpoints.
- Analysis of data from patients with hypertension, type 2 diabetes, stroke, renal disease, heart failure, left-ventricular hypertrophy, and coronary heart diseases.
Main Results:
- ARBs selectively block the angiotensin II type 1 receptor, mitigating harmful angiotensin II effects.
- Studies demonstrate ARB benefits beyond blood pressure control, including preventing type 2 diabetes.
- ARBs ameliorate vascular endothelial dysfunction and reduce markers of vascular inflammation.
Conclusions:
- ARBs are recommended as first-line agents for hypertension and cardiovascular diseases.
- Blocking the renin-angiotensin system with ARBs offers unique vascular and antiatherosclerotic advantages.
- ARBs provide enhanced cardiovascular and renal protection for patients at risk or with existing cardiovascular disease.
Purpose Of Review:
To review the antihypertensive, cardiovascular and pleiotropic effects of angiotensin-receptor blockers (ARBs).
Recent Findings:
ARBs are the most recently approved class of antihypertensive agents. They selectively block the angiotensin II type 1 receptor, thus inhibiting most of the deleterious effects of angiotensin II. In addition to blood-pressure control, other benefits may be gained using ARBs. This is because the renin-angiotensin system plays a crucial role in circulatory homoeostasis, and in patients with atherosclerosis, diabetes or hypertension, angiotensin II contributes to the pathophysiology of disease. Evidence-based medicine includes well-controlled studies with mortality and morbidity endpoints in patients with a variety of conditions including hypertension, type 2 diabetes, stroke, renal disease, heart failure, left-ventricular hypertrophy and coronary heart diseases. In addition to these hard endpoints, it has been shown that treatment with ARBs prevents the development of type 2 diabetes, ameliorates coronary and peripheral vascular endothelial dysfunction and decreases plasma levels of several markers of vascular inflammation.
Summary:
ARBs are first-line agents for the treatment of hypertension and cardiovascular diseases. Blocking the renin-angiotensin system with these agents has special advantages due to specific vascular and antiatherosclerotic effects, which contribute to a better cardiovascular and renal protection in patients at risk from or with cardiovascular disease.
