Ruborg R, et al. - Here, the physicians investigated which factors predicted temperature elevation within 48 h of stroke onset. Moreover, they aimed to test the hypothesis that temperature elevation would be correlated with stroke symptom severity and that hemorrhagic stroke would cause a more pronounced temperature increase compared to ischemic stroke. Within the first 48 h of stroke onset, temperature elevation was common, could be partially predicted using information at admission and was strongly correlated with stroke severity. The strong association with stroke severity could, at least partly, explained the previously described association between post-stroke temperature elevation and unfavorable outcome.
