慢性阻塞性肺病(COPD)可能伴有严重血液动力学障碍而致肺动脉高压。低氧性肺血管收缩和肺血管床减少可促使肺动脉高压的发展。正常右心室在充盈压变化不大时,可适应体循环静脉回流的变化,若肺动脉压明显增高,右心室的适应能力减低,甚至导致 Chronic obstructive pulmonary disease (COPD) may be accompanied by severe hemodynamic disorders resulting in pulmonary hypertension. Hypoxic pulmonary vasoconstriction and pulmonary vascular bed reduction can promote the development of pulmonary hypertension. Right ventricular filling pressure in the little change can adapt to changes in systemic venous return, if significantly increased pulmonary artery pressure, reducing the ability to adapt to the right ventricle, and even lead to
