Abstract:
Objective:To analyze the risk factors for postoperative cardiovascular events (PCE) after renal transplantation and their impact on transplant kidney function.Methods:The clinical data of 120 patients who underwent kidney transplant at Xuanwu Hospital, Capital Medical University from March 2020 to March 2022 were retrospectively analyzed. Among them, 23 cases occurred PCE (PCE group), and 97 cases did not occur PCE (non-PCE group). The relevant preoperative and postoperative data were recorded. Multivariate Logistic regression was used to analyze the independent risk factors of PCE in kidney transplant patients.Results:The incidence rate of PCE in kidney transplant patients was 19.17% (23/120). There were no statistical differences in the gender composition, preoperative dyslipidemia rate, preoperative hypertension rate and immunosuppressant use between two groups ( P>0.05); the age, preoperative body mass index>30 kg/m 2 rate, preoperative dialysis time>12 months rate, preoperative diabetes rate, preoperative cardiovascular disease rate, preoperative diabetic nephropathy rate, cadaver kidney transplant rate, postoperative dyslipidemia rate, postoperative serum creatinine >200 μmol/L rate, postoperative new-onset diabetes rate, postoperative delayed failure rate and postoperative acute reaction rate in PCE group were significantly higher than those in non-PCE group, and there were statistical differences ( P<0.01 or <0.05). Multivariate Logistic regression analysis showed that age, preoperative diabetes, preoperative cardiovascular disease, preoperative diabetic nephropathy, postoperative serum creatinine >200 μmol/L and postoperative acute reaction were independent risk factors of PCE in kidney transplant patients ( OR = 2.40, 3.42, 3.85, 1.98, 2.62 and 2.11; 95% CI 1.67 to 3.58, 1.61 to 7.05, 2.61 to 5.55, 1.05 to 3.85, 1.25 to 4.52 and 1.20 to 4.78; P<0.01 or <0.05). There was no statistically significant difference in serum creatinine 3 months after surgery between two groups ( P>0.05); the serum creatinine 6 and 12 months after surgery in PCE group was significantly higher than that in non-PCE group: (139.58 ± 31.54) μmol/L vs. (105.36 ± 21.05) μmol/L and (198.32 ± 40.12) μmol/L vs. (107.63 ± 24.64) μmol/L, and there were statistical differences ( P<0.01). Conclusions:The incidence of PCE in kidney transplant patients is higher, and there are many risk factors for PCE. If relevant measures are taken to correct or remove risk factors, it may reduce the incidence of PCE and prolong survival time in kidney transplant patients.
