Abstract:
Objective To investigate the correlation between micro?bleeds and hemorrhagic transformation( HT ) after ischemic stroke. Methods One hundred and forty?five cases patients with acute ischemic stroke who were admitted to Luhe Hospital of Beijing Affiliated to Capital Medical University from 2009 to 2014 were retrospective analyzed. The MBs T2??weighted gradient?echo MRI was performed within 48 hours after admission to examine if there was a micro?bleeds,and the incidence of HT was assessed using follow?up brain MRI or CT in 2 weeks after admission. There were 125 patients with stroke were in without HT group and 20 patients were in HT group. Results There were no significant differences in terms of MBs ( P=0. 170 ) , gender( P=0. 671 ) , age ( P=0. 528 ) , hypertension ( P=0. 597 ) , diabetes ( P=0. 571 ) , hyperlipidaemia ( P=0. 772),smoking(P=0. 672),history of stroke(P=0. 469),coagulation function(P=0. 527),antiplatelet(P=0. 642),anticoagulation(P=0. 611) in HT group and without HT group. Atrial fibrillation((45%(9/20) vs. 22%( 28/125 ) , P = 0. 034 ) , NIHSS score ( 10. 9 ± 0. 5 ) points vs. ( 7. 8 ± 1. 2 ) points, P<0. 001 ) , thrombolysis(20% (4/20) vs.5% (6/125),P = 0.015) have significant differences in two groups.In multivariate logistic regression analysis,atrial fibrillation( OR=2. 421,95%CI 1. 823-3. 256,P=0. 012) ,NIHSS score( OR=9. 303, 95%CI 3. 094-27. 970, P<0. 001 ) were independent predictors for HT after ischemic stroke. Conclusion There is no relationship between MBs and HT after ischemic stroke. Atrial fibrillation,the severe of stroke are independent predictors for HT after ischemic stroke.
