慢性阻塞性肺疾病(COPD)是一种以气流持续受限为特征的疾病,肺动脉高压PH)是COPD的重要并发症。COPD合并PH是指COPD患者在静息状态下,用右心导管测得的平均肺动脉压(mPAP)≥25mmHg,肺毛细血管楔压(PCWP)≤15mmHg,心输出量(CD)正常或减少[1]。2008年在美国Dang Point召开的第四届世界肺动脉高压研讨会颁布的PH诊治指南,将COPD合并PH归类与第三组,即肺部疾病和(或)低氧所致PH[2]。鉴于运
Chronic Obstructive Pulmonary Disease (COPD), a disease characterized by persistent airflow limitation, pulmonary hypertension (PH), is an important complication of COPD. COPD with PH is defined as mean normal pulmonary artery pressure (mPAP) ≥25 mmHg, pulmonary capillary wedge pressure (PCWP) ≤15 mmHg, and normal cardiac output (CD) in COPD patients at rest under normal conditions [ 1]. The PH guidelines for treatment and treatment of PH at the Fourth World Pulmonary Hypertension Symposium held at Dang Point, United States in 2008, classify COPD with PH in the third group, PH in lung disease and / or hypoxia [2].
