Abstract:
Objective To investigate the different pathogeneses of asymptomatic lacunar infaction and symptomatic nonlacunar infaction by investigating their risk factors.Methods A total of 1989 people more than 50 years old,performed physical examination were chosen with the results showing 48 patients with asymptomatic lacunar infaction (group A) and 51 patients with symptomatic nonlacunar infaction (group B).Another 1862 controls without cerebrovascular disease were also chosen.Single factor analysis and logistic regression analysis were used to analyze the risk factors.Each risk factor and amount of risk factors for the two diseases was compared between group A and group B.Results Age,hypertension and smoking were the independent predictors of asymptomatic lacunar infaction (P＜0.05).Age,sex,diabetes mellitus,drinking,family history of stroke and stenosis of intracrianial artery were the independent predictors of the symptomatic nonlacunar infaction (P＜0.05).Both rates of diabetes mellitus and stenosis of intracrianial artery in group B were higher than those in group A (diabetes mellitus:x2=17.603,P=0.008; stenosis of intracrianial artery:x2=19.319,P=0.005).The amount of risk factors in patients from group B was significantly more than that in patients from group A (Z=2598,P=0.009).Conclusion The risk factors and vascular mechanism in patients with symptomatic nonlacunar infaction and asymptomatic lacunar infaction are different.Diabetes mellitus and stenosis of intracrianial artery are more often noted in patients with symptomatic nonlacunar infarction.
