Background: Postoperative ischemic stroke is a major adverse effect following Coronary Artery Bypass Graft surgery (CABG). This study evaluates the prevalence, risk factors, and clinical outcomes of postoperative stroke patients undergoing CABG surgery in Bangladesh. Methods: This current study evaluates the predictors of postoperative stroke (n=19, 1.72%) in 1100 consecutive patients who underwent CABG from July 2010 to June 2019 in single surgeon practice. Predictors of postoperative ischemic stroke were identified by logistic regression analysis. Results: Risk factors analysis of stroke significantly correlates with recent MI (P=0.01), previous stroke or TIA (P<0.001), carotid artery stenosis (P<0.001), elderly age (P=0.008), hypertension (P<0.001), diabetes (P=0.001), atrial fibrillation (P<0.001), and severe left ventricular dysfunction (P=0.01). Moreover, postoperative ischemic stroke was significantly associated with longer postoperative stay (<0.001) as well as higher in-hospital mortality (P<0.001). Conclusion: Ischemic stroke after CABG surgery is associated with a higher incidence of postoperative early morbidity and mortality. Furthermore, the prevalence of postoperative stroke following CABG can be predicted and managed by preoperative as well as postoperative early evaluation and risk factors management.
