Abstract
In patients affected by hearth failure (HF) one of the major determinants of quality of life is functional limitation during effort. Oxygen uptake at peak exercise (VO2 peak) assessed through cardiopulmonary test (CPET) is nowadays a strong prognostic predictor in HF and it is also commonly used to monitor patients’ functional status. As per present literature, a change of speed in left ventricular assistance device (LVAD) at rest causes a variation in CO, but is not related to better exercise capacity. In the present analysis, we tested the hypothesis that the change of pump speed during exercise in patients wearing LVAD might be associated with a better exercise performance.
