Influencing factors and guiding significance of troponin I increased after renal transplantation / 中国医师进修杂志

ABSTRACT

Objective:To explore the influencing factors and guiding significance of troponin I (TnI) increased in patients with renal transplantation.Methods:The clinical data of 195 patients with renal transplantation from December 2019 to June 2021 in Xuanwu Hospital, Capital Medical University were retrospectively analyzed. TnI was routinely detected after surgery, and TnI>0.02 μg/L was abnormal. The incidence of acute coronary syndrome during hospitalization was recorded. Multivariate Logistic regression analysis was used to analyze the independent risk factors of TnI increased after renal transplantation.Results:Among 195 patients with renal transplantation, postoperative TnI increased in 55 cases (28.2%). The age, diabetes complication rate and dialysis time before first renal transplantation in patients with TnI increased were significantly higher than those in patients with TnI normal: (49.2±9.0) years old vs. (41.6±10.6) years old, 27.3% (15/55) vs. 14.3% (20/140) and 24.0 (11.0, 60.0) months vs. 11.0 (4.0, 24.0) months, and there were statistical differences ( P<0.01 or<0.05); there was no statistical difference in hospitalization length of stays ( P>0.05). During hospitalization, acute coronary syndrome occurred in 8 patients (4.1%, 8/195), and 2 patients died. Multivariate Logistic regression analysis result showed that age>50 years old was the independent risk factor of TnI increased after renal transplantation ( OR = 5.11, 95% CI 2.47 to 10.59, P<0.01). Conclusions:The incidence of TnI increased after renal transplantation is high, but the incidence of acute coronary syndrome is not high. The age increases the risk of postoperative TnI increased, but TnI increased does not prolong the hospital stay.
