Background: Cerebrovascular accidents (CVAs) after surgical myocar-dial revascularization is one of the most hazardous complication. Its -related mortality remains high and patients who experienc*e this event have lower long-term survival than patients who do not . Many reports focus on the relationship between the degree of atherosclerotic affection of the ascending aorta ; degree of manipulation and postoperative CVAs . Different surgical strategies for myocardial revascularization with the least manipulation to the aorta of these patients were described in the literatures. Other independent predictors of cerebrovascular accidents ( CVAs) following onpump isolated CABG(s) include Extracoronary Vas-culopathy ,Low output syndrome ,Low CF. and others Identification of other risk factors allows preoperative risk stratification and may facilitate improved patient selection and contribute to reduce the risk of a stroke by providing an opportunity for adequate medical and surgical intervention. Objective: Identification of the independent predictors of cerebrovascu-lar accidents ( CVAs ) following onpump isolated CABG(s). Methods: A retrospective study on a total of ( 1192 ) isolated coronary patients whom were operated upon ONPUMP at the Department of Car-diology and Cardiac Surgery, "G. D'Annunzio" University, Chieti, Italy , From January 1991 to December 2001. The patients who survived less than 24 hours and who had aortic cannulation without cross-clamping were excluded.Univariate and multivariate analyses were applied to iden-tify independent predictors of higher incidence of CVAs. Results: Our study demonstrated that (23) patients out of the total num-ber ( 1192 ) patients had experienced CVAs with an incidence of ( 1.93% ) . Univariate analysis of risk factors in patients with and without a CVAs showed that there are seven independent factors: Low Output Syndrome ( LOS ) ( p .000 ) & Simultaneous (CEA) (p .000) & LV dysfunction ( EF |
