Prospective study on soluble thrombomodulin and von Willebrand factor and the risk of ischemic and hemorrhagic stroke.
The aim of the present study was to examine if soluble thrombomodulin (sTM) and von Willebrand factor (VWF) could predict a first-ever ischemic or hemorrhagic stroke. This study was an incident case-referent study from within a population-based cohort in northern Sweden. Up to 1996 about 44,000 subjects had been screened and stroke cases were classified according to the WHO MONICA criteria. A first-ever stroke occurred in 108 cases. A total of 216 controls were selected from the same cohort. This prospective study found no association with sTM or VWF and the development of a first-ever ischemic stroke (n = 87) in the logistic regression model. For the hemorrhagic stroke cases (n = 18), the multivariate logistic regression model revealed a significant negative association with sTM. When dichotomized, the upper level (>17.3 microg/L) of sTM, as compared with the lower level (<17.3 microg/L), showed one fifth of the risk for hemorrhagic stroke (OR, 0.18; CI, 0.05 to 0.69). No significant association was found for VWF. We suggest that the novel finding of an inverse relation between sTM and hemorrhagic stroke should be investigated in a larger study.
