Prognostic value of Cardiopulmonary Exercise Testing in Heart Failure with preserved Ejection Fraction. The Henry Ford HospITal CardioPulmonary EXercise Testing (FIT-CPX) Project

摘要

BackgroundAlthough cardiopulmonary exercise (CPX) testing in patients with heart failure and reduced ejection fraction (HFrEF) is well established, there is limited data on the value of CPX variables in patients with HF and preserved EF (HFpEF). We sought to determine the prognostic value of select CPX measures in patients with HFpEF.
