Research Article: PIF Promotes Autophagy to Inhibit Chronic Hypoxia Induced Apoptosis of Pulmonary Artery Endothelial Cells
Introduction:
Pulmonary artery hypertension (PAH) is a common complication of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea/hypopnea syndrome (OSAHS) worldwide. PAH predominantly affects patients with severe COPD and predicts a poor prognosis. PAH occurs due to occlusion, blockage, and remodeling of the pulmonary vasculature. Long-term home oxygen therapy is the most effective treatment to slow or reverse PAH progression in COPD patients. OSAHS is characterized by intermittent hypoxia during sleep,…
