Abstract:
Objective To evaluate the value of myocardial perfusion change before and after coronary artery bypass grafting (CABG) in predicting postoperative major adverse cardiovascular events (MACE). Methods A total of 70 CABG patients who received CABG completed by the same operator from January to November 2017 were selected, including 45 males and 25 females with an average age of 64.83±9.09 years. The patients were divided into two groups according to whether the patients had MACE after 1 year of the surgery, including a non-MACE group (group A, n=60) and a MACE group (group B, n=10). The clinical data of patients were compared. Results There were statistical difference in the myocardial contrast echocardiography (MCE) score in the group A before and after surgery (P<0.05), and there were statistically significant differences in the left ventricular size and left ventricular ejection fraction (LVEF) value before and 1 year after surgery (P<0.001), but no statistically significant difference in the size of left atrium (P=0.075). There was no significant difference in the preoperative and postoperative MCE score, and preoperative and postoperative 1-year cardiac ultrasound score in the group B (P>0.05). Conclusion The change of myocardial perfusion after CABG surgery is associated with postoperative MACE. The evaluation of myocardial perfusion before and after CABG surgery is of great significance for the prognosis evaluation of patients.
