The Relationship between Recent Infection and Cerebral Infarction

Objective:The aim of this study was to investigate the relationship between recent infection and cerebral infarction.Methods:A prospective case-control study was carnied out with 145 patients,aged 33 to 82 years,with acute cerebral infarction and 145 randomly selected hospitalized patients from noninflammatory diseases matched in pairs for sex,age,and area of residence were served as control.Results:Infection within 1 week before ictus was significantly more common among patients with cerebral infarction than that of the controls( P <0 01).Infection in the preceding week was a factor of risk for cerebral infaction(odds ratio OR 4 4;95% confidence interval(CI),2 6 to 6 34).Both viral and bacterial infections would increase the risk.Recent infection increased the risk for cerebral infarction in all age groups and remained a significant risk factor when other vascular risk factor were included as covariance in a logistic regression(OR,4 6;95% CI,2 2 to 8 54).Conclusions:Recent infection is an important and independent risk factor for cerebral infarction in all age groups.
