About

Patients with a left ventricular assist device (LVAD) will be randomized to either a moderate continuous (MCT, 50-60% of VO2peak) or interval training (IT, 80-90% of VO2peak) group for 6 weeks with 3 sessions per week, lasting for 20 minutes. An additional 10 minutes of resistance training will be performed in each group. Improvement of VO2peak and quality of life (KCCQ score) between the groups will be assessed.

Full description

In- and out-patients with left ventricular assist device (LVAD) will be recruited to participate. On consent to participate, patients will be randomized to either moderate continuous (MCT) or interval (IT) training. An initial cardiopulmonary exercise test (CPET) will be performed to assess exercise intensity levels using a ramp protocol. Baseline quality of life (KCCQ score), echocardiographic and LVAD parameters, lab works, including NTproBNP, a 6min walk distance (6 MWD) will be assessed. Patients will then receive 6 weeks of supervised training in our facility (3x/week, 30min each). Following these sessions CPET, lab works, KCCQ assessment, 6 MWD, and echocardiography will be performed to assess improvement of exercise capacity.

Patients in the MCT group will receive 20min of moderate, continuous bicycle training at an intensity of 50-60% of VO2peak, the IT group will increase exercise density by increasing the duration of intense bouts (80-90% of VO2peak) over the weeks. All groups will receive an additional 10 minutes of resistance training (total exercise time 30 minutes in both groups). Improvement of VO2peak and quality of life (KCCQ score) between the groups will be assessed.
