Objective To explore whether preoperative coronary angiography could increase the incidence of postoperative acute kidney injury for patients with valve replacement. Methods A total of 638 patients underwent routine cardiac valve replacement in our hospital from January 2013 through September 2015. There were 118 patients with preoperative coronary angiography (a coronary angiography group), and 520 patients without coronary angiography (a non-coronary angiography group). Serum creatinine (Scr), urea nitrogen(Bun), brain natriuretic peptide (BNP), creatine kinase myocardial band (CK-MB), cardiac troponin I (cTnI) values were recorded at 4 time points:before surgery (T0), after surgery 12 h (T1), 24 h (T2), 48 h (T3). The number of patients with acute kidney injury at the time of 48 hours after surgery was recorded. Results Scr values (91.6±37.7 μmol/L vs. 81.0±27.4 μmol/L, 84.9±23.6 μmol/L vs. 73.5±25.3 μmol/L) increased in the patients who did not undergo coronary angiography at the time of 24 hours and 48 hours after cardiac surgery compared with the patients with coronary angiography with statistical differences. While there was no statistical difference in the incidence of acute kidney injury between the two groups. The cardiac enzymes had no statistical difference between the two groups. Conclusion Preoperative coronary angiography does not increase the probability of postoperative acute kidney injury.
