中文摘要：

目的：比较北京地区（大城市）、泰州地区（中小城市）急性缺血性脑卒中患者常见危险因素。方法：收集北京朝阳医院神经内科2007—05至2009—08因急性缺血性脑卒中住院的674例病例；泰州人民医院神经内科2009-01至2011-07因急性缺血性脑卒中住院的846例病例。通过调查问卷、体格检查和生化检测收集急性缺血性脑卒中相关危险因素的资料并进行统计分析。结果：急性缺血性脑卒中患者的发病年龄：北京地区患者（均数61．4岁）较泰州地区患者（均数70．9岁）年轻。危险因素暴露比例：肥胖，北京地区患者（21．4％）较泰州地区患者（9．2％）高；吸烟，北京地区患者（58．8％）较泰州地区患者（50．5％）高；高血压，北京地区患者（78．2％）较泰州地区患者（72．2％）高；糖尿病，北京地区患者（35．3％）较泰州地区患者（28．3％）高；高脂血症，北京地区患者（46．0％）较泰州地区患者（34．3％）高；饮酒，泰州地区患者（35．5％）较北京地区患者（25，1％）高。结论：分别处于不同经济发展水平的城市，其常见脑卒中危险因素对急性缺血性脑卒中发生的影响程度可能不同。北京地区（大城市）高血压、糖尿病、高血脂、吸烟等危险因素暴露比例较高，更应注意防寒，限盐，减压，少吸烟，少食高脂肪、高热量食物等。泰州地区（中小城市）在预防高血压的同时，应注意控制饮酒，降低饮酒带来的危害。

英文摘要：

Objective： To compare the common risk factors for in-hospital patients with acute ischemic stroke （AIS） between Beijing and Taizhou residents. Methods： There 2 groups of in-hospital AIS patients from Beijing （big city） and Taizhou （middle-small city） were studied. Beijing resident group, the patients were treated in Beijing Chaoyang Hospital from May 2007 to August 2009, n=674, and Taizhou resident group, the patients were treated in Taizhou People＇s Hospital from January 2009 to July 2011, n=846. The AIS related risk factors were collected with questionnaire, physical and biochemical examinations and the differences between 2 groups were compared by statistics analysis. Results： The average age for AIS onset in Beijing resident group （61.4 years） was younger than that in Taizhou resident group （70.09 years）, Beijing resident group had more patients with obesity （21.4% vs 9.2%）, more patients with smoking history （58.8% vs 50.5%）, more hypertension （78.2% vs 72.2%）, more diabetes mellitus （35.3% vs 28.3%） and more hyperlipidemia （46.0% vs 34.3%）. While the incidence of alcohol drinking in Taizhou resident group （35.5%） was higher than that in Beijing resident group （25.1%）. Conclusion： The common risk factors for AIS onset could vary from different levels of economic development between big and middle-small cities.
