ABSTRACT
@#Objective    To explore the difference of myocardial injury between off-pump coronary artery bypass grafting (OPCAB) and modified perfusion on-pump coronary artery bypass grafting (ONCAB). Methods    A total of 558 patients who underwent coronary artery bypass grafting in Beijing Anzhen Hospital from 2017 to 2019 were included. According to whether or not they received modified perfusion cardiopulmonary bypass, all the 558 patients were divided into two groups including an OPCAB group (OP group) and an ONCAB group (ON group). There were 465 patients in the OP group including 282 males and 183 females with an average age of 63.58±7.87 years. In the ON group, there were 93 patients including 64 males and 29 females with an average age of 63.91±7.51 years. Creatine kinase MB (CK-MB) and cardiac specific troponin I (cTnI) were measured 24 hours before operation, 30 minutes after operation, 12 hours after operation, 36 hours after operation and 48 hours after operation. Results    No perioperative death occurred in all patients. CK-MB (5.00 ng/mL vs. 8.60 ng/mL, Z=–2.189, P=0.029) and cTnI (3.00 ng/mL vs. 7.80 ng/mL, Z=–5.307, P=0.000) in postoperative 12 hours in the ON group were less than those in the OP group. CK-MB (5.00 ng/mL vs. 5.60 ng/mL, Z=–2.280, P=0.023) and cTnI (0.10 ng/mL vs. 1.02 ng/mL, Z=–6.418, P=0.000) in postoperative 36 hours in the ON group were less than those in the OP group. cTnI (0.07 ng/mL vs. 0.81 ng/mL, Z=–1.946, P=0.032) in postoperative 48 hours in the ON group was less than that in the OP group. Conclusion    Compared with OPCAB, modified perfusion ONCAB has less myocardial damage.
