Predictors associated with stroke after coronary artery bypass grafting: A systematic review

Seven variables (advanced age, prior cerebrovascular disease/stroke, prior carotid artery stenosis, prior peripheral vascular disease, prior unstable angina, prolonged cardiopulmonary bypass time, and postoperative atrial fibrillation), representing and high atherosclerotic burden, were found to be associated with more perioperative stroke events. Stroke assessment scales should be included to enable a detailed description of stroke morbidity post CABG. Lessons learned from the present study should also help to improve the quality and relevance of future studies on prognostic factors in stroke after CABG.
