RESUMO

Objective@#To observe the perioperative changes of serum thrombomodulin in patients with and without cardiogenic shock undergoing off-pump coronary artery bypass grafting surgery.@*Methods@#A total of 66 patients with coronary artery disease who underwent off-pump coronary artery bypass grafting surgery between June and December 2015 in our hospital were included in this study.The patients were divided into non-cardiogenic shock group (n=51) and shock group (n=15) according to the absence or presence of cardiogenic shock.The clinical data of the two groups were analyzed.Arterial blood samples were collected immediately after anesthesia, and at 4, 8, 16, 24, 48 and 72 hours after surgery.The levels of serum thrombomodulin were tested with enzyme-linked immunosorbent assay.@*Results@#(1)The prevalence of diabetes was significantly higher (64.7%(33/51) vs. 20.0%(3/15), P<0.01), while prevalence of myocardial infarction was significantly lower (41.2%(21/51)vs. 100%(15/15), P<0.01) in non-cardiogenic shock group than in cardiogenic shock group.(2)The peak plasma creatinine level, troponin I level and creatine kinase MB level were significantly lower in the non-cardiogenic shock group than in the cardiogenic shock group ((88.5±36.7) μmol/L vs. (122.6±71.1) μmol/L, 1.3(0.2, 2.7) μg/L vs. 16.4(5.8, 23.4) μg/L and (18.8±4.7) μg/L vs.(49.3±15.9) μg/L, respectively, all P<0.05). (3)Mechanical ventilation time was significantly longer (11.5 (9.0, 18.0) hours vs. 20.0 (8.5, 82.5) hours, P=0.02), and frequency of intra-aortic balloon pump use (0 vs. 100%, P<0.01) was significantly higher in the cardiogenic shock group than in the non-cardiogenic shock group.(4) Prevalence of atrial fibrillation (5.9%(3/51) vs. 80.0%(12/15)) and myocardial infarction (19.6%(10/51)vs. 93.3%(14/15)) that occurred during and after surgery was significantly lower in the non-cardiogenic shock group than in the shock group(all P<0.01). (5)The serum thrombomodulin concentration was similar among various time point in the non-cardiogenic shock group: 3.30(2.68, 7.44), 4.09(2.95, 7.18), 4.35(2.68, 8.22), 3.50(2.95, 8.00), 3.41(2.60, 5.97), 3.30(2.65, 5.42)and 3.94(2.82, 5.60) μg/L, taken immediately after anesthesia, and at 4, 8, 16, 24, 48 and 72 hours after surgery respectively, and was 2.44(1.97, 2.67), 2.21(1.93, 2.83), 2.64(2.29, 2.67), 2.84(2.26, 2.94), 3.35(2.43, 4.05), 2.76(2.73, 2.97) and 3.81(2.96, 5.96)μg/L respectively, in the cardiac shock group (all P>0.05). The serum thrombomodulin levels at 4 and 8 hours after surgery were higher in the non-cardiogenic shock group than cardiogenic shock group(all P<0.05).@*Conclusion@#Compared with the non-cardiogenic shock group, the peak serum thrombomodulin level appears later and recovers slower in cardiogenic shock patients who underwent off-pump coronary artery bypass grafting surgery.
