脑梗死复发的危险因素对比分析

目的探讨引起脑梗死复发的相关危险因素。方法对2007年1月～2008年1月期间我科收治的103例复发脑梗死患者和同期收治的122例初发脑梗死患者的危险因素进行对比分析。结果通过Logistic回归分析发现年龄（OR=1.015）、脑血管病家族史（OR=1.139）、高血压（OR=1.333）、高纤维蛋白原（OR=1.366）、脑白质疏松（OR=1.488）是增加脑梗死复发的危险因素。复发脑梗死组的危险因素种类明显多于初发脑梗死组（P〈0.05）。复发脑梗死组与初发脑梗死组梗死灶大小比较无明显差异（P〉0.05）。复发的时间多在初发后1年内和5年后。结论脑梗死的复发与多种因素共同作用有关,危险因素越多,复发的机率越大。

The comparative analysis of risk factors for recurrence cerebral infarction

Objective To probe into the cause of related risk factors for recurrence cerebral infarction.Methods A-mong the patients admitted into our department from January 2007 to January 2008,103 cases of patients with recurrence cerebral infarction and 122 cases of patients with initial cerebral infarction were treated in the same period and their risk factors were analyzed.Results Logistic regression analysis showed that age（OR=1.015）,family history of cerebrovascular disease（OR=1.139）,hypertension（OR=1.333）,high fibrinogen（OR=1.366）,leukoaraiosis（OR=1.488） increased the risk for recurrence of cerebral infarction.The number of risk factors of recurrence cerebral infarction group were significantly larger than those of initial cerebral infarction group（P0.05）.Compared infarct size of recurrence cerebral infarction group with that of initial cerebral infarction group,there was no significant difference（P0.05）.Recurrence cerebral infarction occured often within 1 year of the initial attacks and 5 years after the initial attacks.Conclusion The recurrence of cerebral infarction involves combined action of various factors.The more risk factors,the greater the chance of recurrence.
