Abstract

Objective: To investigate the echocardiographic characteristics in patients undergoing maintenance hemodialysis. Subjects and Methods: A cross-sectional descriptive study. The convenience sampling method was used, involving 51 patients who underwent periodic hemodialysis at the Artificial Kidney and Hemodialysis Unit of Bac Thang Long Hospital, and met the inclusion and exclusion criteria. Results: The average age of the patients was 56.0 ± 15.8 years. The patients had an average dialysis duration of 44.0 ± 36.3 months. Among the patients, 35.5% had left ventricular systolic dysfunction, 49.0% had left ventricular diastolic dysfunction, and 31.4% had right ventricular systolic dysfunction. Compared with healthy individuals, the patients had significantly larger (p<0.05) aortic root diameter, left atrial diameter, interventricular septal thickness (in both systole and diastole), left ventricular posterior wall thickness (in both systole and diastole), left ventricular diameter (in systole), left ventricular volume (in both systole and diastole), left ventricular mass, right and mid right ventricle, right ventricular longitudinal axis, proximal and distal right ventricular outflow tract, while ejection fraction, fractional shortening, E wave velocity, E/A ratio, tricuspid annular plane systolic excursion, and right ventricular fractional area significantly lower (p<0.05). Conclusion: Echocardiography is an effective tool for detecting cardiac morphological and functional changes, which are common in patients undergoing maintenance hemodialysis.
