Objective: Hemodialysis can affect the hemodynamics and cardiac function of patients with cyclic hemodialysis. Our study aimed to evaluate and analyze a number of factors related to the change in left ventricular diastolic function after dialysis in patients with cyclic hemodialysis at Bach Mai Hospital.
Subjects and methods: A cross-sectional descriptive study. There were 61 patients with cyclic hemodialysis (n=61) includes in the study. All patients participating in the study were asked about their disease, clinical examination, and echocardiography before and after dialysis.
Results: The average age of the study subjects was 51,5 ± 12,2 years old, of which 31 men accounted for 50,8 %. After dialysis, E wave velocity (89,9 ± 24,1 vs 71,9 ± 24,4 m/s) decreased statistically significantly compared to pre-dialysis with p< 0.0001. Meanwhile, the A wave velocity (96.3 ± 29.0 vs 96.2 ± 29.7 m/s) change insignificantly and there was almost no statistical difference between before and after dialysis with p > 0,05. E/A ratio (1.01 ± 0.4 vs 0.82 ± 0.45, p < 0,05) and mean E/e’ ratio (12.4 ± 4.7 vs 10.6 ± 4,3, p < 0,0001) significantly decreased after dialysis. The flow velocity through the tricuspid valve did not change significantly after dialysis (VmaxTR, 2.5 ± 0.4 vs 2.4 ± 0.4 m/s, p> 0,05). After dialysis, the left atrial volume index decreased significantly compared with before dialysis (LAVi, 42.8 ± 14.8 vs 36.5 ± 14.3 ml/m2) with p < 0,0001. There is a not very close correlation between the dialysis fluid volume and the e' index of the interventricular septum after dialysis in the opposite direction with r = - 0.324 and p = 0.034 < 0.05 with statistical significance.
Conclusion: Echocardiographic assessment of left ventricular systolic and diastolic function had a statistically significant improvement between before and after dialysis. This difference is related to the volume of hemodialysis during that dialysis session.
