A 3-month exercise training program significantly improves exercise capacity in patients with stable systolic chronic heart failure.

Cite This Study

Silva et al. (2002) conducted an RCT in stable systolic chronic heart failure (n=24). Exercise training program vs. Control group was evaluated on Distance walked (p=<0.003). A 3-month exercise training program significantly increased distance walked (to 970 m vs 561 m in controls) in patients with stable systolic chronic heart failure.
