Heart failure & cardiomyopathies
Supervised Exercise Training in Patients with Advanced Heart Failure and Left Ventricular Assist Device: A Multicentre Randomized Controlled Trial (Ex-VAD Trial)
Authors' conclusion
In patients with advanced heart failure and LVAD, 12 weeks of exercise training did not improve peakVO2 but demonstrated positive effects on submaximal exercise capacity and physical quality of life.
