摘要
目的:评价风湿性二尖瓣狭窄(MS)患者心肺功能的相互关系。方法:对32例MS患者进行肺功能和右心导管检查。统计处理采用典型相关分析。结果:小气道功能指标最大呼气中段流速、50%肺活量用力呼气流速和25%肺活量用力呼气流速代表主要肺功能改变,肺小动脉阻力、肺动脉压、肺小动脉嵌顿压代表主要血流动力学改变;对血流动力学变化较敏感的肺功能指标是潮气量、50%肺活量用力呼气流速和25%肺活量用力呼气流速比值、肺活量、最大呼气中段流速;对肺功能变化较敏感的血流动力学指标是心输出量、肺血管阻力、肺小动脉嵌顿压。结论:血流动力学与肺功能之间有显著的相关关系。
? Objective:To evaluate the correlation of cardiac and pulmonary functions in patients with rheumatic mitral stenosis(MS). Methods:Pulmonary function and cardiac catheterization were performed in 32 patients with MS. Results:Abnormalities of main pulmonary function were reflected from the parameters of small airway function including maximal midexpiratory flow rate(MMF),flow at 50 and 25 percents of the forced expired vital capacity(50,25).Changes of main hemodynamic data were reflected from the parameters of pulmonary arteriolar resistance,pulmonary artery pressure and pulmonary artery wedge pressure(PAWP).The tidal volume,50/25,vital capacity and MMF were more sensitive to changes of hemodynamics.The cardiac output,pulmonary vascular resistance and PAWP were more sensitive to changes of pulmonary function. Conclusion:The cause and effect correlation seems present between pulmonary function and hemodynamics.
