Abstract：ObjectiveTo explore the risk factors of ischemic stroke in elderly patients with atrial fibrillation.MethodsThe clinical data of 132 cases of elderly patients with atrial fibrillation in our hospital from February 2013 to February 2015 were analyzed and whether or not with ischemic stroke diagnosed by combination of CT and MRI technology,patients were divided into control group(69 patients with atrial fibrillation alone)and observation group(63 cases of atrial fibrillation associated with ischemic stroke).Risk factors associated with ischemic stroke were analyzed.ResultsRisk factors of atrial fibrillation elderly patients with ischemic stroke were age(χ2=9.791,P=0.001),hypertension(χ2=4.859, P=0.027),type 2 diabetes (χ2=7.283,P=0.007),sustained atrial fibrillation (χ2=15.230,P=0.000),carotid artery plaque (χ2=8.508,P=0.004),left atrial expansion(χ2=8.340,P=0.004).Multivariate Logistic regression model analysis showed that age≥70 years old,hypertension,type 2 diabetes,sustained atrial fibrillation,carotid artery plaque and left atrial expansion were the independent risk factors for ischemic stroke occurrence in elderly patients with atrial fibrillation.ConclusionOlder age,hypertension,type 2 diabetes,sustained atrial fibrillation,carotid artery plaque and left atrial expansion are the risk factors of ischemic stroke in elderly patients with atrial fibrillation.
