多年来,对于COPD 患者运动时肺动脉楔压(PWP)升高的解释有两种观点:一派认为与左心衰竭有关;另一派认为与胸内压的某些因素有关;甚至认为肺气肿时,肺过度充气导致肺毛细血管压缩性陷闭和血管床破坏,因此,PWP 并不能真正反映左心房的压力。但是,近来一些研究结果表明,COPD Over the years there have been two explanations for the rise in pulmonary arterial wedge pressure (PWP) during exercise in COPD patients: one is thought to be associated with left ventricular failure; the other is thought to be associated with certain causes of thoracic pressure; and even the time when emphysema is considered Pulmonary hypercapnia leads to compression of pulmonary capillaries and vascular bed destruction, therefore, PWP does not really reflect the pressure of the left atrium. However, some recent studies have shown that COPD
