目的了解无症状脑梗死的发生率、梗死部位及相关的危险因素。方法对新乡市第一附属医院114例无症状脑梗塞(SCI)患者与92例有症状脑梗塞患者(对照组)的临床资料进行回顾性对照分析。结果两组在年龄、体重、卒中家族史、嗜好烟酒等多项因素以及血液流变、血脂、血糖等方面无显著性差异(P>0.05),但在梗塞灶分布上存在显著性差异(P<0.01),提示病变部位直接影响脑梗塞患者病情轻重及预后转归。结论通过对老年无症状脑梗死患者的调查及危险因素的分析,发现年龄、高血压和糖尿病是无症状脑梗死的主要相关危险因素。
Objective To understand the incidence of asymptomatic cerebral infarction, infarct location and related risk factors. Methods The clinical data of 114 patients with asymptomatic cerebral infarction (SCI) and 92 patients with symptomatic cerebral infarction (control group) in the First Affiliated Hospital of Xinxiang City were retrospectively analyzed. Results There was no significant difference between the two groups in age, weight, family history of stroke, addiction to tobacco and alcohol, blood rheology, blood lipids and blood glucose (P> 0.05), but there was significant difference in the distribution of infarction P <0.01), suggesting that the lesion directly affects the severity of the patients with cerebral infarction and prognosis. Conclusion Through the investigation of elderly patients with asymptomatic cerebral infarction and the analysis of risk factors, age, hypertension and diabetes mellitus are the main risk factors of asymptomatic cerebral infarction.
