The individual changes in plasma relaxin (RLX) levels in patients with ischemic heart disease undergoing ergometric exercise testing grouped according to peak cardiac power output (CPO) less or greater than 1.96 W. Baseline: after 30 min supine rest; max. charge: during peak exercise; recovery: 10 min after peak exercise. a. high degree heart failure (peak CPO < 1.96 W; n = 18); b. low degree heart failure (CPO > 1.96 W; n = 22). Friedman's test followed by Wilcoxon's matched pairs test revealed no significant within group changes. Please note the different scales on the y-axes.
