The postoperative cerebrovascular event in myocardial revascularization surgery is a catastrophic entity that increases morbidity and mortality and costs for medical care. The literature shows a decrease in the incidence of cerebrovascular event after cardiac surgery in the last decade, However, there are no data on the prevalence of this entity in Latin America or Colombia.. objectives: Identify risk factors for the development of early cerebrovascular event, in patients undergoing myocardial revascularization surgery in a Colombian referral center. Methods: Case-control study nested in a retrospective cohort. Results: Were included 876 patients, with average age of 63,6 years ± 9,25 years old, of which the 74,5% they were men. The incidence of postoperative cerebrovascular event was 1,3%. The risk factors were: valve surgery ( OR 43,92 { IC 95% 1,26-1527,05} , p = 0,037) ; previous cerebrovascular event ( OR 14,78 { IC 95% 2,96-73,68} p = 0,01) ; aortic calcification ( OR 8,23 { IC 95% 2,18-31,12} , p = 0,02) . Conclusions: The incidence of postoperative cerebrovascular event of myocardial revascularization surgery in a Colombian referral center is lower than that reported in the world literature. Predictors are valvular surgery, history of cerebrovascular event and identification of aortic calcification.
