Effects of 12 weeks of ramipril treatment on the quality of life in patients with moderate congestive heart failure: Results of a placebo-controlled trial

Abstract

The assessment of quality of life (QoL) has become recognized as an important tool for evaluating heart failure therapy. The angiotensin-converting enzyme inhibitor ramipril (mean dose 8 mg) was evaluated in 223 patients with moderate chronic congestive heart failure at 24 centers in 4 Nordic countries following a randomized, double-blind, placebo-controlled, parallel group design. The follow-up period was 12 weeks. QoL was evaluated using a questionnaire with 47 items, including the disease-specific Severe Heart Failure Questionnaire, the Sleep Dysfunction Scale, and the Psychological General Well-Being Index. In both treatment groups the total score increased from baseline to 12 weeks for both the Severe Heart Failure Questionnaire and for the Psychological Well-Being Index, reflecting relief of symptoms and improved well-being. However, no significant differences between the placebo and ramipril groups could be detected. Only a trend toward improvement in sleep on ramipril compared with placebo therapy was observed. In conclusion, in this placebo-controlled trial no significant effects of 12-week ramipril treatment of QoL could be demonstrated in patients with moderate congestive heart failure.
