Abstract

Background: Pulmonary hypertension is a serious cardiovascular complication in patients with end stage renal disease undergoing hemodialysis via arterio-venous fistulas. Objective: To assess pulmonary hypertension prevalence and identify potential risk factors in maintenance hemodialysis patients. Material and method: A total of 105 maintenance hemodialysis patients were assessed at the Vinh Long General Hospital between August 2023 and October 2023. Relevant parameters included primary disease, dialysis duration, height, weight, and interdialytic weight gain… Doppler echocardiography was performed post-hemodialysis to evaluate cardiac structure and function. Results: Pulmonary hypertension prevalence was 41 % in maintenance hemodialysis patients. Pulmonary hypertension is statistically significantly related to the dialysis duration (months) (p = 0.001), EF (%) (p = 0.02), Fistula surgery time (FAV) (months) (p = 0.003) and EPO used (UI/week) (p = 0.003). Significant Pearson’s correlation was found between pulmonary arterial systolic pressure with the duration of hemodialysis, EF, EPO, hemoglobin level, serum creatinine in maintenance hemodialysis patients.  Ejection fraction (EF %) (p = 0.03), Hemoglobin level (g/L) (p = 0.04) and Hematocrit (%) (p = 0.02) were statistically significantly associated with severity of pulmonary arterial hypertension. Conclusion: Ultrasound assessment of pulmonary artery pressure and aggressive treatment of anemia are needed for patients on routine hemodialysis.
