Figure 1.
Boxplots representing the acute response of the mobilization of each endothelial cellular population after the initial and the final cardiopulmonary exercise training within and between patients with chronic heart failure of high and low severity, based on peak VO2. The asterisk (*) indicates statistically significant difference within each severity group (p < 0.05). No differences were observed between patients of high and low severity in each endothelial cellular population (p > 0.05). CPET, cardiopulmonary exercise test.
