PURPOSE: The purpose of this study was to investigate the effect of a cardiac rehabilitation program on the acute response on endothelial progenitor cells and circulating endothelial cells after maximal exercise in patients with chronic heart failure of different severity.
METHODS: Forty-four chronic heart failure patients were enrolled in a 36-session cardiac rehabilitation program. All patients underwent an initial maximal cardiopulmonary exercise test before and a final maximal cardiopulmonary exercise test after the cardiac rehabilitation program. The patients were divided in two groups of severity according to the median value of peak VO2. Blood was collected at 4 time points; 2 time points at rest, and 2 time points after each cardiopulmonary exercise test. Five endothelial cellular populations were quantified by flow cytometry.
RESULTS: Although there was a higher increase in the mobilization of subgroups of endothelial progenitor cells and circulating endothelial cells after the final cardiopulmonary exercise test compared to the initial test within each severity group (p < 0.05), no significant differences between severity groups were observed (p > 0.05).
CONCLUSIONS: A 36-session cardiac rehabilitation program had similar beneficial effects on the acute response of endothelial progenitor cells and circulating endothelial cells after maximal exercise in patients with chronic heart failure of different severity.
