Background
There has been conflicting evidence of the effect of angiotensin-converting enzyme (ACE) inhibitors on exercise tolerance. Meta-analysis of published results has suggested that a beneficial effect of ACE inhibitors is demonstrated if a trial design is adequate.
Setting
Multicentre International Trial.
Methods
In a double-blind, randomized, multicentre trial, 292 patients with moderate (New York Heart Association Grades II and III) heart failure were treated with trandolapril or placebo in addition to diuretics, and followed for 16 weeks. Exercise tolerance on a treadmill was assessed at baseline and after 4, 8, 12 and 16 weeks of treatment. Both a modified Bruce and a modified Naughton protocol were used.
Results
Exercise tolerance improved in both treatment groups, with no significant benefit from trandolapril treatment.
Conclusion
Trandolapril does not improve exercise tolerance as measured by treadmill testing.
