Key result
Aerobic exercise improves PETCO2 and aerobic capacity by ~23% in a patient with HF-related PH.
Why the study?
Reduced exercise capacity and exertional dyspnea are frequent concerns in patients with pulmonary hypertension due to heart failure, and the effect of aerobic exercise training on pulmonary gas exchange abnormalities is unclear.
Does aerobic exercise training improve PETCO 2 response during exercise in a patient with pulmonary hypertension secondary to idiopathic dilated cardiomyopathy?
Case Report (n=1)
No
Does aerobic exercise training improve PETCO 2 response during exercise in a patient with pulmonary hypertension secondary to idiopathic dilated cardiomyopathy?
Effect estimate: 23.3% improvement
Aerobic exercise training may be a viable intervention to evaluate or improve pulmonary gas exchange abnormalities in patients with pulmonary hypertension due to heart failure.
May support exercise to improve PETCO2 in PH-HF; hypothesis-generating case report requiring prospective validation.

Prado et al. (2021) conducted a case report in Pulmonary hypertension secondary to heart failure (n=1). Aerobic exercise training vs. Pre-intervention baseline was evaluated on Carbon dioxide end-tidal partial pressure (PETCO2) at ventilatory anaerobic threshold (23.3% improvement). A three-month aerobic exercise training program improved PETCO2 at ventilatory anaerobic threshold by 23.3% and aerobic capacity by 23.9% in a patient with pulmonary hypertension due to heart failure.
