为探讨超声心动图在肺心病患者心功能评价中的作用, 本文通过选取2016年1月至2018年1月期间本院呼吸内科住院部肺心病患者80例作为病例组, 同期选取本院健康体检中心的健康体检者80例作为对照组, 对全部研究对象进行超声心动图检查。二维超声心动图测定左心室收缩末期内径(LVESD)、左心室舒张末期内径(LVEDD)、舒张期室间隔厚度(IVSD)、左心室后壁厚度(LVPWd)、室壁相对厚度(RWT)、左心室心肌指数(LVMI)、左心室射血分数(LVEF)、肺动脉主干内径(MPAD)、右心房横径(RAD) 、右心室前后径(RVD)、右心室面积变化率(RV-FAC)。多普勒超声心动图测定肺动脉收缩压(PASP), 三尖瓣环收缩期峰值速度( s’)、三尖瓣环收缩期位移(TAPSE)、三尖瓣舒张早期血流速度(E)与三尖瓣环舒张早期峰值速度(E’)的比值(E/E’)、三尖瓣舒张期血流速度比值(E/A)与右心室心肌做功指数(RV-MPI)。结果显示病例组LVESD、LVEDD、IVSD、LVPWd、RWT、LVMI、MPAD、RAD 、RVD与PASP均明显高于对照组, P<0.05, LVEF明显低于对照组, P<0.05。病例组s’、TAPSE、RV-FAC明显低于对照组, P<0.05。病例组E/E’与RV-MPI明显高于对照组, E/A明显低于对照组, P<0.05。因此, 超声心动图在肺心病患者心功能评价中的作用显著, 在指导临床治疗方案的制定中具有重要的意义。

To study the role of doppler echocardiography in evaluating cardiac function in patients with pulmonary heart disease. 80 cases of patients with pulmonary heart disease from respiratory medicine inpatient department of our hospital during the period of January 2016 and January 2018 were selected as case group, at the same time, 80 cases of healthy check-up from our physical examination center were selected as control group, all object were given echocardiography. Two-dimensional echocardiography was used to determine left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic diameter (LVEDD), interventricular septal thickness (IVSD), left ventricular posterior wall, thickness(LVPWd), relative wall thickness (RWT), left ventricle myocardium index (LVMI), left ventricular ejection fraction (LVEF), main pulmonary artery diameter (MPAD), right atrial diameter (RAD), right ventricular diameter (RVD),right ventricular fractional area change (RV-FAC).Doppler echocardiography was used to determine pulmonary artery systolic pressure (PASP), ricuspid annulus systolicpeak velocity (s’), tricuspid annular plane systolic excursion (TAPSE), E/E’, E/A, right ventricular myocardial performance index (RV-MPI). Results showed that LVESD, LVEDD, IVSD, LVPWd,RWT, LVMI, MPAD, RAD, RVD and PASP of case group were significantly higher than that of the control group, P<0.05. LVEF was lower than the control group, P<0.05. The indexes of s’, TAPSE, RV-FAC in case group were significantly lower than the control group, P<0.05. E/E’ and RV - MPI of case group were significantly higher than the control group, E/A was significantly lower than the control group, P<0.05. Therefore, the role of echocardiography in evaluating cardiac function in patients with pulmonary heart disease is significant, it has the vital significance in guiding clinical treatment plan formulation.
