[Post-COVID Rehabilitation].

COVID-19 is a multi-organ disease with a broad spectrum of manifestations. Many affected individuals have major difficulties in resuming their previous daily routine or occupation as a result of the disease. Currently, no causal therapeutic approaches are available for the treatment of post-COVID disease.

Effect of oxygen therapy on exercise performance in patients with cyanotic congenital heart disease: Randomized-controlled trial.

Background: Patients with unrepaired cyanotic congenital heart disease (CHD) suffer from aggravated hypoxemia during exercise. We tested the hypothesis that supplemental oxygen improves exercise performance in these patients.

Methods: In this randomized, sham-controlled, single-blind, cross-over trial cyanotic CHD-patients underwent four cycle exercise tests to exhaustion, while breathing either oxygen-enriched (FiO 0.

Effect of Breathing Oxygen-Enriched Air on Exercise Performance in Patients With Pulmonary Hypertension Due to Heart Failure With Preserved Ejection Fraction: A Randomized, Placebo-Controlled, Crossover Trial.

To evaluate the effects of breathing oxygen-enriched air (oxygen) on exercise performance in patients with pulmonary hypertension due to heart failure with preserved ejection fraction (PH-HFpEF). Ten patients with PH-HFpEF (five women, age 60 ± 9 y, mPAP 37 ± 14 mmHg, PAWP 18 ± 2 mmHg, PVR 3 ± 3 WU, resting SpO 98 ± 2%) performed two-cycle incremental exercise tests (IET) and two constant-work-rate exercise test (CWRET) at 75% maximal work-rate ( ), each with ambient air (FiO 0.21) and oxygen (FiO 0.
