Skeletal muscle pathophysiology contributes to reduced exercise capacity and exercise intolerance in patients with pulmonary arterial hypertension.
Skeletal muscle pathology is increasingly recognized as a contributing factor to exercise intolerance in pulmonary arterial hypertension.
Pulmonary arterial hypertension is a disease of the pulmonary vasculature, resulting in elevated pressure in the pulmonary arteries and disrupting the physiological coordination between the right heart and the pulmonary circulation. Exercise intolerance is one of the primary symptons of pulmonary arterial hypertension, significantly impacting the quality of life. The pathophysiology of exercise intolerance in pulmonary arterial hypertension is complex and likely multifactorial. Although the significance of right ventricle impairment and perfusion/ventilation mismatch is widely acknowledged, recent studies suggest pathophysiology of the skeletal muscle contributes to reduced exercise capacity in pulmonary arterial hypertension, a concept explored herein.
