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

摘要: Background Stroke is a major cause of morbidity and mortality after coronary artery bypass grafting (CABG). The purpose this systematic review was to evaluate the predictors perioperative stroke CABG. Methods We reviewed published literature on prognostic factors for CABG in articles using multivariate regression models. statistical validity models qualitative synthesis were performed. Results We identified 14 studies. methodological quality study reporting variable. Overall, incidence 1.1–5.7%. About 37–59% strokes occurred early (intraoperatively). No validated outcome scale used assess any included Advanced age, prior (before CABG) cerebrovascular disease/stroke, carotid stenosis, peripheral vascular disease, unstable angina, prolonged cardiopulmonary time found be most consistent independent CABG. Postoperative atrial fibrillations variables associated with postoperative association hypercholesterolemia, myocardial infarct, smoking. Other risk factors, such as gender, hypertension, diabetes mellitus, congestive heart failure, chronic renal showed inconsistent results. Conclusions Seven (advanced time, fibrillation), representing high atherosclerotic burden, more events. Stroke assessment scales should enable detailed description post Lessons learned from present also help improve relevance future studies
