rn目的探讨慢性阻塞性肺疾病(COPD)患者肺动脉收缩压(sPAP)与病程、心功能、肺功能及动脉血气的相关性,以及sPAP评估COPD预后的价值。方法回顾107例COPD患者资料,分析sPAP与病程、心脏射血分数(EF)、FEV1%、pH、PaO2、PaCO2的相关性,比较肺动脉高压(PH)患者与非肺动脉高压(NPH)患者的2年累积生存率。结果 sPAP与病程正相关,与FEV1%、PaO2负相关(P“,”Objective To investigate the significance of pulmonary arterial systolic pressure(sPAP) in evaluating the prognosis of patients with chronic obstructive pulmonary disease(COPD).Methods Data of 107 COPD patients and the correlation between sPAP and COPD course,cardiac ejection fraction(EF),FEV1%,pH,PaO2 and PaCO2 were retrospectively analyzed.The two-year surivial rate was compared between the patients with pulmonary hypertension(group PH) and those without PH(group NPH).Results The sPAP was positively correlated to the COPD course,negatively correlated to the FEV1% and PaO2(P<0.05).The two-year surivial rate was lower in group PH than that in group NPH(39.6% vs.76.6%)(P<0.01).Conclusion The sPAP is closely correlated to the COPD course and pulmonary function.The two-year surivial rate is lower in the patients with PH than that in those without PH.
