Abstract: Objective To investigate the risk factors of in-hospital cerebral infarction with carotid artery ultrasound parameters for postcardiotomy patients. Methods The data of 491 adult patients who underwent cardiac surgery in Beijing Anzhen Hospital, Capital Medical University from January 2020 to December 2020 were retrospectively analyzed. The patients were divided into cerebral infarction and control group. The risk factors were analyzed via univariate and multivariate Logistic regression. Results The total incidence of in-hospital cerebral infarction in postcardiotomy patients was 1.8%, and the survival rate of patients complicated with cerebral infarction was 77.8%. The higher European system for cardiac operative risk evaluation (EuroSCORE) II level (OR=1.585, 95%CI: 1.043-2.409), bilateral cervical and vertebral artery plaques (OR=14.513, 95%CI: 2.538-82.978), extracorporeal membrane oxygenation (ECMO) support (OR=112.518, 95%CI: 8.967-1 411.907), and new postoperative atrial fibrillation (OR=20.800, 95%CI: 3.639-118.902) were independent risk factors for cerebral infarction after cardiac surgery. Conclusion Besides higher EuroSCORE II, ECMO support and new-oneset postoperative atrial fibrillation, the carotid ultrasound-based bilateral carotid artery and vertebral artery plaques is risk factor for cerebral infarction after cardiac surgery. It is necessary to carry out a preoperative carotid artery ultrasound screening and strict intraoperative and postoperative management for the patients at risk.
