Introduction: Perioperative stroke after coronary artery bypass grafting is a catastrophic complication that increases mobility, mortality and the cost for medical attention. Recently a global decrease in perioperative stroke has been reported, however, there is a lack of data about the prevalence of perioperative stroke in Latin-American and Colombia. Objective: To identify the risk factors for early stroke after coronary artery bypass grafting in a Colombian cardiovascular center. Methods: A retrospective case and control study nested in a cohort was performed. Results: 876 patients were included with a mean age of 63.6 ± 9.25 years, 74.5% were male. The incidence of perioperative stroke was 1.3%. The risk factors identified were: previous valvular surgery OR 43.92 ( 1.26-1527.05) , p:.037, past medical history of stroke OR 14.78 ( 2.96-73.68) , p:.01 and the presence of aortic calcification OR 8.23 ( 2.18-31.12) , p:.02. Conclusions: The incidence of perioperative stroke after coronary artery bypass grafting in a Colombian cardiovascular center is lower than reported in the literature, the perioperative predictors identified in the present study were previous valvular surgery, the past medical history of stroke and aortic calcification.
