Key result
Controlled exercise training safely improved peak VO2 and maximal work rate in patients with dilated cardiomyopathy and ejection fraction <20%.
Why the study?
Does a controlled exercise training program improve exercise capacity and reduce arrhythmia severity in patients with dilated cardiomyopathy and ejection fraction <20%?
Does a controlled exercise training program improve exercise capacity and reduce arrhythmia severity in patients with dilated cardiomyopathy and ejection fraction <20%?
Controlled exercise training is safe and significantly improves exercise capacity in patients with dilated cardiomyopathy and severely reduced ejection fraction (<20%).
May support supervised exercise in severe DCM; hypothesis-generating pending RCTs on arrhythmia and outcomes.
The results of this pilot study suggest that patients with a diminished ejection fraction as low as 16% can safely perform an exercise program. A significant improvement in peak VO2 and maximal work rate was achieved. Moreover, this study suggests that exercise training might diminish the severity of asymptomatic ventricular arrhythmia; however a larger controlled study is needed to confirm these findings.

Mager et al. (2000) studied Dilated cardiomyopathy with ejection fraction <20%. Controlled exercise training was evaluated on Peak VO2 and maximal work rate. Controlled exercise training safely improved peak VO2 and maximal work rate in patients with dilated cardiomyopathy and ejection fraction <20%.
