Right ventricular strain by speckle tracking echocardiography in patients with end-stage chronic kidney disease undergoing renal transplantation
Nội dung chính của bài viết
Tóm tắt
Objective: To evaluate right ventricular strain by speckle tracking echocardiography in patients with end-stage chronic kidney disease before and 1 month after kidney transplantation. Subjects and methods: The study included 63 patients diagnosed with end-stage chronic kidney disease. All patients received kidney transplantation at Military Hospital 103 from October 2023 to April 2025. They were followed up for 1 month after kidney transplantation. Right ventricular strain was evaluated before and 1 month after successful kidney transplantation. All informed consents were obtained from participants, and the research was approved by the Ethics Council of Military Hospital 103, Military Medical Academy. Results: RV4CLS ( -17.56 ± 4.82 vs -21.14 ± 3.90, p < 0.01) and RVFWLS (-20.59 ± 6.10 vs -24.81 ± 4.58, p < 0,01) 1 month after kidney transplantation improved significantly compared with pre-transplantation. The rate of right ventricular dysfunction group decreased significantly 1 month after transplantation (40.5 vs 13.5 %, p < 0.01). RV4CSL and RVFWSL after transplantation in the pre-transplant pre-emptive treatment group were statistically higher than in the hemodialysis group. RV4CSL had a moderate positive correlation with the time of dialysis before kidney transplantation. RV4CSL had a moderate positive correlation with hemoglobin level before kidney transplantation. Conclusion: RV4CSL and RVFWSL 1 month after kidney transplantation improved significantly compared with pre-transplantation. The rate of the right ventricular dysfunction group also decreased significantly. RV strain was also associated moderately with the type of pretransplant renal replacement therapy, the duration of dialysis, and the hemoglobin level.
