| description | Spontaneous subarachnoid hemorrhage (SAH) can occur unexpectedly and independently
of the classic risk factors. Several different factors could affect intracranial aneurysm (IA)
rupture, such as morphological and hemodynamic factors. The aim of this study was to establish the
potential association of meteorological data such as temperature, atmospheric pressure, and humidity,
and the onset of clinical symptoms preceding hospital admission of patients with acute SAH due to
IA rupture. This retrospective study included 130 consecutive patients admitted for non-traumatic
SAH with a determinable onset of SAH symptoms. The effects of meteorological parameters of atmospheric
pressure, ambient temperature, and relative air humidity on the day of acute SAH onset and
24 hours prior to the onset of symptoms were recorded and analyzed in each patient. Spearman rank
correlation analysis was used to assess the risks of incident SAH on the basis of daily meteorological
data. Seasonal incidence of acute SAH showed the peak incidence in winter and a trough in summer,
with monthly incidence peak in January and December. The circadian rhythm analysis showed the
peak incidence of SAH in the forenoon, followed by the evening. Acute SAH incidence showed moderate
positive association with daily atmospheric pressure (p<0.05), while no association was found
with ambient temperature and relative air humidity. Our results suggested no significant association of
changes in ambient temperature and relative humidity with the risk of SAH. Increases in atmospheric
pressure were weakly associated with a higher SAH risk. Additional studies are needed to establish
in detail both meteorological and morphological factors important to predict IA rupture and SAH. |
