本文分析了47例怀疑为肺动脉高压病人的右心室射血分数与肺动脉高压的关系。全部病人进行r相机平衡法核素心室造影,测定右心室射血分数。行右心导管检查,测定右房压、右室压、肺动脉压。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COPD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,右心室射血分数在评价肺动脉高压病人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。
This article analyzes the relationship between right ventricular ejection fraction and pulmonary hypertension in 47 suspected pulmonary hypertension patients. All patients were r camera balance method radionuclide ventriculography, determination of right ventricular ejection fraction. OK right heart catheterization, determination of right atrial pressure, right ventricular pressure, pulmonary pressure. The negative correlation between RVEF and mean pulmonary artery pressure was found in 47 patients (r = -0.43, P <0.01). The negative correlation between RVEF and mean pulmonary artery pressure in 21 patients with COPD was r = -0.53 (P <0.02) Right ventricular ejection fraction in the evaluation of patients with pulmonary hypertension in patients with right heart function involvement and efficacy of the observation of the value, but direct diagnosis of pulmonary hypertension is of little significance.
