title: [Effect of captopril on the exercise performance in patients with congestive heart failure].
abstract: We studied the effect of captopril on exercise performance in 30 patients with congestive heart failure using a randomized, double-blind and placebo-controlled method. 4-week captopril treatment can significantly increase the exercise tolerance time and work load, heart function, blood flow in exercising lower limbs as well as oxygen metabolic capacity. However, 3-day captopril treatment had no effect on exercise performance. A significant correlation was found between improvement in exercise performance and the pretreatment level of plasma angiotensin II. The increased levels of plasma prostaglandins E 2 and I 2 after captopril treatment were also correlated with improvement of exercise performance. The results indicated that long-term captopril treatment can increase exercise performance in congestive heart failure by improving both central and peripheral hemodynamics and metabolism. Certain vasomotor or endocrine factor may play a mediate role in the above changes.
