  • Prognostic significance of test of cardiac troponin T and renal function in acute type A aortic dissection

    Objective To measure the rate of changes of the cardiac troponin T (cTnT) and serum urea nitrogen (N), serum creatinine (Cr), estimated glomerular filtration rate (eGFR) of acute type A aortic dissection (AAAD) patients before and after surgery, and to explore the prognostic significance of the rate of changes. Methods We retrospectively analyzed 77 AAAD patients' clinical data between August 2015 and March 2016 from the department of the cardiothoracic surgery in Nanjing Drum Tower Hospital. There were 57 males and 20 females with an average age of 51.1±13.1 years. The test results of cTnT, N, Cr, eGFR were recorded. Patients were divided into three groups based on the duration of ventilation: less than 48 hours, 48 hours to 7 days, longer than 7 days, and divided into two groups based on whether postoperative dialysis was performed: dialysis group and non-dialysis group. Results In the groups with different duration of ventilation, the rate of cTnT change differed significantly. The rate of Cr and eGFR change in the group with the duration of ventilation longer than 7 days showed significantly different compared to other two groups. We found that the rate of Cr and eGFR change were statistically significant between the dialysis group and the non-dialysis group. In the receiver operating characteristic curve (ROC), the optimal cut-off value of the Cr growth rate for predicting postoperative dialysis therapy was 58.1%, and the optimal cut-off value of the eGFR decline rate was 45.5%. Conclusion The rate of changes in cTnT, N, Cr and eGFR can be used as a reliable mean to evaluate respiratory and renal function for AAAD patients in the early stage, which will facilitate an early assessment of the prognosis of AAAD patients.
