| 目的探讨维持性血液透析尿毒症患者右心室壁局部心肌运动参数与左心室功能指标的关系。方法选取维持性血液透析的尿毒症患者135例（血液透析组）和体检的正常成人41例（正常对照组）为研究对象，均进行超声心动图检查，测定右心室前、下、侧壁的基底段、中段、心尖段心肌的收缩期组织速度和位移，以及舒张早、晚期组织速度。比较两组受检者右心室壁局部心肌运动参数与左心室功能指标，并分析血液透析组患者右心室壁心肌运动参数与左心室功能指标的相关性。结果血液透析组患者大部分右心室壁心肌运动参数与左心室功能指标均低于正常对照组（均P＜0.05）。血液透析组患者侧壁基底段收缩期组织速度与左心室心输出量相关性较强（r=0.31，P＜0.05），直线回归方程为Y=0.28X＋4.76；下壁中段收缩期组织位移与二尖瓣环舒张晚期速度相关性较强（r=0.25，P＜0.05），直线回归方程为Y=0.37X＋10.02。结论维持性血液透析尿毒症患者左心室整体收缩与舒张功能对右心室壁局部心肌运动有一定影响，同时右心室壁局部心肌运动可反映左心室整体心功能。 |

| Abstract: |
| Objective To explore the relationship between the parameters of myocardial motions of right ventricular walls and the indices of cardiac functions of left ventricle in uremic patients with maintenance hemodialysis. Methods One hundred and thirty five uremic patients with maintenance hemodialysis (hemodialysis group) and 41 healthy subjects (control group) were enrolled in the study. The systolic tissue velocity, systolic tissue displacement, early distolic velocity and atrial systolic velocity of every segment of right ventricle were measured by echocardiography, and the parameters of myocardial motions of right ventricular walls and the indices of cardiac functions of left ventricle were compared between two groups. The linear regression correlation between the parameters of myocardial motions of right ventricular walls and the indices of cardiac functions of left ventricle in patients of hemodialysis group was analyzed. Results The parameters of myocardial motions of right ventricular wall
and the indices of cardiac functions of left ventricle in the patients of hemodialysis group were lower than those in control group (all P＜0.05). The systolic velocity of basal segment of lateral wall (LVbs) was correlated with left ventricular cardiac output (LVCO) in hemodialysis group (r =0.31, P＜0.05) with a linear regression equation of Y =0.28X ＋4.76. The systolic displacement of mid segment of inferior wall (IDms) was correlated with atrial velocity of mitral valve annulus (MVa) (r = 0.25, P＜0.05) with a linear regression equation of Y =0.37X ＋10.02. Conclusion In the uremic patients with hemodialysis, the integral systolic and diastolic
function of left ventricle can affect the myocardial motions of right ventricular wall; on the contrary, the right ventricular regional myocardial motions can reflect the left ventricular integral function. |
