Relationship between Left Ventricular Diastolic Dysfunction and Mitral Regurgitation in Patients with Maintenance Hemodialysis
Abstract：Objective To study the relationship between left ventricular diastolic dysfunction (LVDD)and mitral regurgitation in patients with maintenance hemodialysis (MHD).Methods Parameters relating to cardiac structure and function were assayed with Doppler echocardiography in MHD patients.The clinical data were also col ected.Sixty three patients with MHD were divided into two groups based on LVDD.Mitral regurgitation was found.Al data were compared between 2 groups.Results LVDD was confirmed in 20 of 63 patients (31.75%).Mitral regurgitation were increased significantly in non LVDD group compared to LVDD group (P<0.01). Gender,duration in hemodialysis,left atrial enlargement,mitral valve calcification,were increased significantly in LVDD group com-pared to non LVDD group (P<0.05).Logistic regression found that there was a negative correlation between LVDD and mitral re-gurgitation.Left atrial enlargement,mitral valve calcification were the major correlative factors for LVDD.Conclusion Mild mitral regur-gitation may reduced the incidence of LVDD.Duration in hemodialysis,left atrial enlargement and mitral valve calcification were corre-lated with LVDD.
