Abstract:
Objective To analyze the risk factors and clinical features of stroke following off-pump coronary artery bypass grafting in patients with prior stroke. Methods From January 2006 to July 2009, the clinical information of 437 patients undergoing OPCABC in Anzhen Hospital was collected. The patients were divided into stroke group and non-stroke group according to whether stroke occurred after operation. Preoperative and operative variants were evaluated by univariate and multivariate logistic stepwise regression analysis. Results 32 of 437 patients (7.3% ) suffered from stroke after OPCABG, 32 cases were cerebral infarction and no case was cerebral hemorrhage. There were more patients whose left ventricular ejection fraction ≤0. 50 in stroke group than that in non-stroke group (12 of 32, 37.5% versus 69 of 405, 17.0% , P = 0. 004), more patients had atrial fibrillation after operation in stroke group than that in non-stroke group (9 of 32, 28. 1% versus 27 of 405,6.7% , P ＜ 0.001), more patients had hypotension after operation in stroke group than that in non-stroke group (13 of 32,40.6% versus 42 of 405, 10. 4% ; P ＜ 0. 001), more patients had ventilatory time and ICU time after operation in stroke group than that in non-stroke group(9 of 32, 28.1% versus 49 of 405, 12.1% , P =0.021; 14of 32,43.8% versus 97 of 405, 24.0% , P = 0.013), and patients in stroke group took longer to stay in hospital than that in non-stroke group (29.0 ±15. 8 versus 22. 9 ± 10. 4, P = 0. 002 ). Logistic stepwise regression analysis showed that left ventricular ejection fraction SS0.50(OR=2.837, 95%CI: 1.238-6.498), atrial fibrillation after operation( OR =3. 065, 95% CI: 1.157-8.118) and hypotension after operation (OR =4.209, 95%CI: 1.805 -9. 813) were independent risk factors of stroke following offpump coronary artery bypass grafting in patients with prior stroke. Conclusion This data suggest that left ventricular ejection fraction ≤0. 50, atrial fibrillation and hypotension after operation are risk factors for stroke following off-pump coronary artery bypass grafting in patients with prior stroke. These patients with stroke after operation took longer to extubate and stay in ICU and hospital.
