Heart Failure Clinical Trial
Official title:
Daily Physical Activity at Pulse Pressure Above an Individual Threshold in Patients With Continuous Flow Left Ventricular Assist Devices - a Feasibility Study
Pilot study in patients with continuous flow left ventricular assist device (cfLVAD) to
proof the feasibility of a specific individual training at home aimed to increase pulse
pressure above a predefined threshold which might attenuate the loss of arterial wall
thickness.
Hypothesis:
Increasing daily physical activity near to normal (> 10.000 steps per day) with a
pre-defined level of pulse pressure (intensity) is a realizable and feasible approach to
investigate changes in arterial wall thickness and cardio-respiratory capacity in cfLVAD
patients.
The investigators will study 3 cfLVAD patients with low pulse pressure during work package 1
using two different exercises, treadmill and bicycle. Walking and cycling present the most
commonly used physical activities which are applicable to most individuals on a daily basis.
The investigators aim to demonstrate that individual changes of pulse pressure during these
types of exercise can be assessed in cfLVAD patients.
In a feasibility study (work package 2) the investigator will enroll 6 cfLVAD patients to
perform home-based physical activity programs including walking a defined number of steps
per day with a predefined speed and cycling with a predefined power [watt] on a bicycle
ergometer. The performance of the patients will be monitored over seven days using a
wearable activity device.
