多发性脑梗死与单发性脑梗死危险因素对比分析

目的比较多发性脑梗死（MCI）与单发性脑梗死（SCI）的危险因素，以利于对其进行针对性的防治。方法前瞻性连续登记神经内科缺血性脑卒中患者，根据临床和影像学资料分为MCI和SCI组，对可能影响多发性脑梗死发病的24项因素先进行单因素分析，比较可能的危险因素在MCI与SCI组间有无差异，然后进行非条件logistic多元回归分析，校正混杂因素的影响。结果年龄、性别、高血压、糖尿病、心瓣膜病、吸烟、脑梗死史、入院首次收缩压等危险因素在MCI与SCI组间有显著差异，logistic多元回归分析显示，年龄OR=1.014，95％CI（1.003，1.026）]、高血压OR=1.566，95％CI（1.185，2.068）]、吸烟OR=1.473，95％CI（1.052，2.061）]、脑梗死史OR=1.948，95％CI（1.326，2.864）]为MCI的独立危险因素。结论与SCI相比，年龄、高血压、吸烟、脑梗死史为MCI的独立危险因素。

Comparison Analysis of Risk Factors between Multiple Cerebral Infarction and Single Cerebral Infarction

Objective To compare the risk factors between multiple cerebral infarction (MCI) and single cerebral infarction (SCI). This would be beneficial for carrying out corresponding prevention and treatment. Methods We prospectively registered consecutive cases of ischemic stroke in the neurological wards and divided them into two groups: MCI group and SCI group according to their clinical and imaging data. Firstly, the single variable analyses of 24 factors that could be related to the onset of MCI were conducted, and then the multivariate non-condition stepwise logistic regression was performed. Results Significant differences were noted between MCI group and SCI group in terms of age, gender, hypertension, diabetes, heart valvular disease, smoking, cerebral infarction history and first systolic blood pressure after admission. The logistic regression analyses showed that factors of age (OR=1.014, 95%CI 1.003 to 1.026), hypertension (OR=1.566, 95%CI 1.185 to 2.068), smoking (OR=1.473, 95%CI 1.052 to 2.061), cerebral infarction history (OR=1.948, 95%CI 1.326 to 2.864) were independent risk factors for MCI. Conclusion Compared to SCI, age, hypertension, smoking and cerebral infarction history were independent risk factors for MCI patients.
