ACE inhibitors in congestive heart failure
1Department of Family Medicine, Texas Tech University Health Sciences Center, Lubbock.
Insights
Congestive heart failure (CHF) management is improved with angiotensin-converting enzyme (ACE) inhibitors. Combining ACE inhibitors with diuretics, and possibly digitalis, maximizes clinical benefit for patients with mild to moderate CHF.
Area of Science:
- Cardiology
- Pharmacology
Background:
- Congestive heart failure (CHF) remains a significant clinical challenge despite advances in understanding disease mechanisms and care quality.
- Traditional CHF treatments include diuretics and digitalis, which are still central to patient management.
Purpose of the Study:
- To evaluate the role of angiotensin-converting enzyme (ACE) inhibitors as an addition to traditional CHF therapies.
- To assess the impact of ACE inhibitors on symptoms and survival in CHF patients.
Main Methods:
- Review of recent evidence on CHF treatment strategies.
- Analysis of the effects of ACE inhibitors on the renin-angiotensin-aldosterone system.
Main Results:
- Angiotensin-converting enzyme (ACE) inhibitors counteract diuretic-induced overstimulation of the renin-angiotensin-aldosterone system.
- Studies suggest ACE inhibitors can improve CHF symptoms and patient survival.
Conclusions:
- For mild to moderate CHF, the combination of an ACE inhibitor and a diuretic is recommended.
- Digitalis may be added to the ACE inhibitor and diuretic regimen for maximum clinical benefit in CHF patients.
Abstract:
Despite improved understanding of both disease mechanisms and the quality of care, congestive heart failure (CHF) remains a serious clinical problem. The traditional treatments, diuretics and digitalis, continue to play a major role in the management of many patients with CHF; however, in the last decade, angiotensin-converting enzyme (ACE) inhibitors have been added as an important treatment option. These agents counteract the overstimulation effects of diuretics on the renin-angiotensin-aldosterone system. In addition, some studies indicate that ACE inhibitors may improve symptoms and survival. Recent evidence suggests that in patients with mild to moderate CHF, ACE inhibitor and a diuretic should be administered with or without digitalis to achieve the maximum clinical benefit.
