Markers of Endothelial Function and Exercise CapaciTy in Patients With Left Ventricular Assist Devices (EFECT LVAD)

This is a non-randomized, feasibility study of endothelial function, exercise capacity, and outcome following pre-LVAD patients through LVAD therapy and cardiac transplantation. The study period will be 5 years. It is anticipated that 20 patients will be enrolled and 15 will survive (published survival estimate following LVAD is approximately 75% at one year) to complete the one-year follow-up period. 10 patients are anticipated to undergo heart transplant within 3 years of initial enrollment and they will be followed until their 2nd annual post-transplant invasive evaluation.
