Abstract
Aim To assess impacts of different weather conditions on hospitalizations of patients with ischemic strokes and subarachnoid hemorrhages (SAH) in South Florida.
Methods Diagnostic data of patients with spontaneous SAH and strokes were recorded between June 2010 and July 2013. Daily synchronous forecast charts were collected from the National Weather Service and the whole data were matched prospectively. The incidence rate ratio (IRR) was calculated.
Results Increased incidence rate of ischemic stroke was consistent with the daily lowest and highest air pressure (IRR 1.03, P = 0.128 and IRR 0.98, P = 0.380, respectively), highest air temperature (IRR 0.99, P = 0.375), and presence of hurricanes or storms (IRR 0.65, P = 0.054). Increased incidence of SAH cases was consistent with daily lowest and highest air pressure (IRR 0.87, P < 0.001 and IRR 1.08, P = 0.019, respectively) and highest air temperature (IRR 0.98, P < 0.001). Presence of hurricanes and/or tropical storms did not influence the frequency of SAH. We found no relationship between the presence of fronts and the admissions for ischemic stroke or SAH.
Conclusion Higher number of ischemic stroke and SAH cases can be expected with the daily lowest and highest air pressure, highest air temperature. Presence of hurricanes or tropical storms increased the risk of ischemic stroke but not the SAH. These findings can help to develop preventive health plans for cerebrovascular diseases.
