摘要
本文分析了47例怀疑为肺动脉高压患者的右心室射血分数(RVEF)与肺动脉高压的关系。47例患者的RVEF与肺动脉平均压呈中度负相关(r=-0.43,P<0.01),21例慢性阻塞性肺部疾患患者的RVEF与肺动脉平均压呈负相关(r=-0.53,P<0.02)。结果显示,RVEF在评价肺动脉高压患者的右心功能受累程度及药物疗效观察有价值,但对直接诊断肺动脉高压意义不大。
The correlation between right ventricular ejection fraction (RVEF) and pulmonary hypertension was studied in 47 patients including 21 with chronic obstructive pulmonary disease (COPD), 14 with primary pulmonary hypertension and 12 with pulmonary embolism (PE). Equilibrium radionuclide ventriculography and right heart catheterization were performed in all patients. A moderately negative correlation was found between RVEF and pulmonary arterial pressure (r=-0.43, P<0.01). In the COPD group the correlation was -0.53 (P<0.02). Right ventricular ejection fraction tends to reduce with increase of pulmonary arterial pressure, so right ventricular ejection fraction is a useful parameter in assessing the degree of right ventricular dysfunction in patients with pulmonary hypertension. However, it can not be used to measure pulmonary hypertension directly.
