成都市心血管疾病患者中脑卒中高危人群研究报告

目的：调查成都市心血管疾病患者脑卒中高危人群所占的比例，评价各项脑卒中高危因素在脑卒中的作用。方法纳入2011年11月~2012年11月四川省人民医院心血管疾病患者9174例，根据弗明翰（Framingham）卒中风险评估得分对所有患者进行评分，将男性≥10分和女性≥6分定义为脑卒中高危人群，统计高危人群在入组人群中所占比例，并统计各项脑卒中高危因素[包括高血压、脑血管疾病（包括卒中史）、糖尿病、左心室肥厚、房颤、吸烟]的发生率。结果脑卒中高危人群在入组患者中占比52.46%（4813/9174），其中男性较女性高危人群占比更高[69.99%（2831/4045）vs.38.64%（1982/5129）]，差异有统计学意义（P＜0.05）；在脑卒中的高危因素中，最常见的是脑血管疾病史（86.72%），其次是高血压（59.01%），所纳入的脑卒中危险因素中仅吸烟在男性的发生率高于女性，其他均是女性高于男性。结论成都市心血管疾病患者中脑卒中高危患者比例较高，而高危因素中又以脑血管病史和高血压最为主要。

Report on high stroke-risk group in patients with cardiovascular diseases in Chengdu

Objective To investigate the proportion of high stroke-risk group in the patients with cardiovascular diseases in Chengdu City, and review the roles of high-risk factors in stroke attack.Methods The patients （n=9174） were chosen from the Sichuan Provincial People’s Hospital from Nov. 2011 to Nov. 2012. All patients were graded according to Framingham risk score of stroke. The male patients with scores≥10 and female ones with scores≥6 were defined high stroke-risk group. The proportion of high stroke-risk group in all patients and the incidences of high-risk factors of stroke （including hypertension, cerebrovascular diseases, diabetes, left ventricular ypertrophy, atrial fibrillation and smoking） were calculated.Results The proportion of high stroke-risk group was 52.46% （4813/9174）, and the proportion of the male was higher than that of the female [69.99%（2831/4045）vs. 38.64% （1982/5129）,P〈0.05]. Among the high-risk factors of stroke, the most common one was cerebrovascular diseases （86.72%） and second one was hypertension （59.01%）. In all high-risk factors of stroke, the incidence of only smoking was higher in the male, and others were higher in the female.Conclusion The proportion of high stroke-risk patients is higher in Chengdu City, and high-risk factors of stroke are mainly cerebrovascular diseases and hypertension.
