Congestive Heart Failure (CHF) and Angiotensin-Converting Enzyme (ACE) Inhibitors

Read more about Angiotensin-Converting Enzyme (ACE) Inhibitors.


A number of studies have shown that ACE inhibitors are beneficial in reducing symptoms and prolonging life in patients with congestive heart failure (CHF). These medications should be considered in all patients who have CHF. Talk with your doctor to see if an ACE inhibitor is right for you.

Common ACE inhibitors include:

  • Captopril (Capoten)
  • Enalapril (Vasotec)
  • Lisinopril (Zestril, Prinivil)
  • Benazepril (Lotensin)
  • Quinapril (Accupril)
  • Ramipril (Altace)
  • Fosinopril (Monopril)
  • Moexipril (Univasc)
  • Trandolapril
  • Perindopril

Effect of Angiotensin-Converting Enzyme (ACE) Inhibitors on Congestive Heart Failure (CHF)

ACE inhibitors prevent the body from creating angiotensin II, a substance in the blood that causes vessels to tighten and raises blood pressure. As a result, ACE inhibitors relax blood vessels, lower blood pressure, and ease the heart’s workload.

Side Effects and Warnings

Possible side effects of ACE inhibitors include:

  • Cough
  • Headache
  • Dizziness
  • Increased levels of potassium in the blood, altered kidney function
  • Altered sense of taste
  • Low blood pressure
  • Swelling
  • Skin rashes
