Abstract/OtherAbstract:
There have been numerous studies of the relationship between intracerebral hemorrhage (ICH) and meteorological conditions, but their conclusions have been inconsistent. Poor discrimination of ICH subtypes (primary or secondary) may have obscured the conclusions. Although most studies have analyzed seasonal or monthly variation, daily meteorological data are more appropriate for determining whether weather conditions play a role in triggering the onset of ICH. No studies have examined the activity and location of patients at the time of onset. The aim of this study was to evaluate the relationship between the occurrence of hypertensive ICH and daily meteorological parameters, in addition to examining the effect of the location and activity of the patient at the time of onset. We analyzed 138 patients with severe hypertensive ICH in a hospital-based population. We assessed whether daily meteorological parameters for the days on which ICH occurred differed from the days without ICH onset. Days on which hypertensive ICH occurred had a significantly lower minimum temperature and a decreased minimum temperature from that of the previous day ( P=0.042 [corrected] and 0.012 [corrected] respectively). There were no significant differences among subgroups of patients categorized according to their location and activity at the time of onset for any of the meteorological parameters.
