Effect of Short-term Oxygen During CPET in HFpEF
March 11, 2021 updated by: University of Zurich
Effect of Short-term Ambulatory Oxygen Therapy on Cardiopulmonary Exercise Capacity (CPET) in Patients With Heart Failure With Preserved Ejection Fraction (HFpEF)
In a randomized, sham-controlled crossover trial the investigators will test whether supplemental oxygen given during cardiopulmonary exercise testing will improve exercise performance and physiological parameters in patients with heart failure with preserved ejection fraction.
