Factor XII Concentrations and Risk of Intracerebral Haemorrhage : A Prospective Case-Referent Study

• Objectives: In a previous pilot study, we found an association between high factorXII levels and risk of haemorrhagic stroke suggesting that factor XII is a risk markerfor intracerebral haemorrhage (ICH). The aim of this study was to further investigate the association between factor XII and risk of ICH in a larger population.Materials and Methods:This study was conducted as a prospective nested case-referent study. All participants underwent a health examination and blood sampling for factor XII analysis at baseline. Cases were defined as participants who were diagnosed with a first-ever ICH between 1985 and 2000. Two referents were matched to eachcase.Results:We identified 70 individuals withfirst-ever ICH and 137 matchedreferents who had undergone a health examination and donated blood samples Factor XII Concentrations and Risk of Intracerebral Haemorrhage. A Prospective Case-Referent Studybefore the ICH event. The mean age was 54 years, and 33% were women. The median time-to-event was 3.5 years (range 0.04 to 10.2 years). Conditional logistic regression showed no association between factor XII and risk of ICH, (odds ratio1.06 per SD; [95% confidence interval: 0.57–1.97] in a multivariable model).Conclusions: A previous finding of an association between high concentration of factor XII and risk of ICH could not be replicated in this larger study
