Abstract Objective: To contrast the incidence of HT between large artery atherothrombosis (LAA) and cardioembolism (CE), and to investgate the risk factors for hemorhagic transformation (HT) in patients with anterior circulation infarction who was attributed to cardioembolism (CE) or large artery atherothrombosis (LAA). Methods: The clinical data of 560 acute ischemic stroke patients admitted to Wenzhou First Hospital Affiliated to Wenzhou Medical University between January 2010 and December 2012 were retrospectively collected. They were divided into HT group and non-HT group. Baseline demographic and clinical information collected included gender, age at onset, hypertension, diabetes, atrial fibrillation, systolic blood pressure and diastolic blood pressure levels, fasting blood glucose level, levels of TC and low-density lipoprotein cholesterol, National Institute of Health Stroke Scale (NIHSS) score at admission, infarct size, use of antiplatelet or anticoagulant medications and statins treatment. Univariate analysis was performed using idependent-Student’s t-tests (for continuous variables) and chi-square test (for categorical variables) for each of the predictors of interest. Subsequent multivariable modeling included the presence of HT as the dependent variable in stepwise logistic regression. Results: Statins use [odds ratio (OR)=0.212, 95% confidence interval (CI): 0.067-0.672], antiplatelet treatment (OR=0.170, 95%CI: 0.074-0.388) and the NIHSS score (OR=1.088, 95%CI: 1.02-1.16) were predictors of hemorrhagic transformation in LAA patients, while antiplatelet treatment (OR=2.224, 95%CI: 1.142-4.330) and blood glucose level (OR=2.168, 95%CI: 1.131-4.155) in CE patients. Conclusion: A higher HT rate found in the CE group than that in the LAA group. In LAA patients, statins used and antiplatelet treatment can lower the incidence of HT while NIHSS score may be a risk factor.But antiplatelet trentment and high blood glucose level may be the possible risk factors in CE patients.
