An increase in wedge pressure distinguishes right heart strain due to pulmonary congestion from cor pulmonale with normal pulmonary capillary pressure. Pulmonary hypertension might be due to exogenous hypoxia, obstructive sleep apnea, acute and chronic airway obstruction, diseases of the lung parenchyma, and vascular bed impairment of the thoracopulmonary mechanics, including neurogenic and muscular disorders, cardiac insufficiency of the left heart, and valvular diseases.
楔压升高可将因肺充血导致的右心劳损与肺毛细血管压力正常的肺心病区分开来。肺动脉高压可能由外源性缺氧、阻塞性睡眠呼吸暂停、急慢性气道阻塞、肺实质疾病、胸肺力学的血管床损害（包括神经源性和肌肉性疾病）、左心心脏功能不全以及瓣膜疾病引起。
