血液透析尿毒症患者右心室壁心肌运动与左心室功能的关系研究
Relationship between myocardial motions of right ventricular walls and cardiac functions of left ventricle in uremic patients with maintenance hemodialysis
摘要
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.关键词
