Abstract

Objectives: To investigate the relationship between pulmonary artery pressure index on Doppler echocardiography and some clinical and paraclinical parameters in people with chronic kidney disease stages 3 - 5 who have not received alternative treatment at the Bach Mai hospital. Subjects and methods: Cross-sectional descriptive study of 102 patients with chronic kidney disease stages 3 - 5 who have not received alternative treatment at the Kidney - Urology and Dialysis Center of Bach Mai Hospital from January 2023 to October 2023. Results: The average age of the study subjects was 54.68 ± 17.2 years old, the youngest was 18 years old, and the oldest was 83 years old. Female patients account for a higher proportion of 51%. The average pulmonary artery pressure (PAPs) in the study was 33.79 ± 9.5 mmHg, the lowest was 20mmHg, and the highest was 67mmHg. The rate of increased PAPs in stage 5 kidney disease is 75%, stage 4 is 15% and stage 3 is 10%. The rate of increased PAPs in patients with mild anemia is 40%, and in patients with moderate anemia is 60%. PAPs do not depend on the patient's age or BMI. PAPs were negatively correlated with left ventricular ejection fraction (r=-0.389, p = 0.0), and positively correlated with longitudinal right ventricular diameter (r=0.302, p =0.002). Conclusion: PAPs depend on the stage of chronic kidney disease, the more severe the stage, the higher the rate of increase in PAPs. PAPs are related to the patient's anemia, negatively correlated with left ventricular ejection fraction, and positively correlated with longitudinal right ventricular diameter.
