We looked for risk factors for significant carotid stenosis (CS) in patients with ischemic stroke. We included all patients treated for an ischemic stroke/transient ischemic attack (TIA) and had a carotid duplex done from August 2006 to November 2008. A total of 458 patients were included. Significant CS of the extracranial internal carotid artery and the common carotid artery were found in 10.9% (50 of 458 patients). Age (≥65 years old) was the independent risk factor for CS (OR 4.0, P < .0001). The patients with a CS had more history of coronary artery disease (12% vs 8%, P = .32), prior ischemic stroke (18% vs 11%, P = .17), atrial fibrillation (10% vs 5%, P = .19), and smoking (28% vs 24%, P = .18) compared with the patients without CS. The evaluation of the carotid arteries should be recommended in patients with ischemic stroke/TIA, especially in the older ones (≥65 years old).
我们研究了缺血性脑卒中患者发生颈动脉狭窄（CS）的危险因素。我们纳入了 2006 年 8 月至 2008 年 11 月间所有因缺血性脑卒中/短暂性脑缺血发作（TIA）而接受治疗并接受颈动脉双功能超声检查的患者。共纳入了 458 例患者。发现颅外颈内动脉和颈总动脉存在明显 CS 的患者占 10.9%（458 例患者中有 50 例）。年龄（≥65 岁）是 CS 的独立危险因素（OR 4.0，P<.0001）。与无 CS 的患者相比，CS 患者具有更多的冠心病病史（12% vs 8%，P=.32）、既往缺血性脑卒中病史（18% vs 11%，P=.17）、心房颤动病史（10% vs 5%，P=.19）和吸烟史（28% vs 24%，P=.18）。对于缺血性脑卒中/TIA 患者，尤其是年龄较大（≥65 岁）的患者，应推荐评估颈动脉。
