Quality of life with ACE inhibitors in chronic heart failure.

The randomized trials assessing the effect of angiotensin-converting enzyme (ACE) inhibitors in chronic heart failure (CHF) are reviewed. The Minnesota Living with Heart Failure Questionnaire has demonstrated the benefits of enalapril in some but not all circumstances and the Yale Dyspnea-Fatigue Index improves with lisinopril. A recent trial of both cilazapril and captopril vs. placebo employed the Sickness Impact Profile and supports the concept that ACE inhibitors have a small (and in this trial nonsignificant) beneficial effect on mobility. Other vasodilators and inotropes may also have small benefits on quality of life, such that comparisons of an ACE inhibitor with vasodilators, as was done in the V-HeFT II trial, fail to reveal any different effects on quality of life.
