“…Favoring our results in case of SAH, a recent Korean study suggested that the daily temperature swings may influence the risk of spontaneous intracerebral hemorrhage (13). Studies performed in Siberia and in France also failed to report an association between any one of the weather parameters studied and the occurrence of SAH (14,15). We suspect that the lack of warmer weather conditions in these regions compared to Florida limited those studies to achieve a link between air temperature and the occurrence of SAH in contrast to our findings.…”

AimTo assess impacts of different weather conditions on hospitalizations of patients with ischemic strokes and subarachnoid hemorrhages (SAH) in South Florida.MethodsDiagnostic 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.ResultsIncreased 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.ConclusionHigher 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.

“…Several authors [ 1 , 17 , 19 , 20 ] indicated that colder daily temperatures were associated with an increased risk of SAH. On the other hand, more recent studies reported that no relationship was observed between temperature changes and the occurrence of SAH [ 4 , 18 , 21 – 23 ].…”

BackgroundThe purpose of this study is to determine whether intracerebral hemorrhage and subarachnoid hemorrhage have different incidence patterns based on monthly variations in meteorological and air pollution parameters in the Seongdong district of Seoul, South Korea.MethodsFrom January 1, 2004 to December 31, 2014, 1,477 consecutive hemorrhagic stroke events (>19 years old) were registered among residents of the Seongdong district, Seoul, South Korea. The authors calculated the relative risk of hemorrhagic stroke and its subtype incidence based on meteorological and air pollution factors. We also estimated relative risk with 95 % confidence intervals using a multivariate Poisson regression model to identify potential independent variables among meteorological factors and pollutants associated with either intracerebral hemorrhage or subarachnoid hemorrhage occurrence.ResultsWe observed a negative correlation between intracerebral hemorrhage and mean temperature. In the multivariate Poisson model, particulate matter with an aerodynamic diameter < 10 μm showed positive correlations with intracerebral hemorrhage (relative risk, 1.09; 95 % confidence interval, 1.02 to 1.15; P = 0.012). In contrast, ozone correlated significantly with subarachnoid hemorrhage occurrence (relative risk, 1.32; 95 % confidence interval, 1.10 to 1.58; P = 0.003).ConclusionsOur findings show the relationship between hemorrhagic stroke and meteorological parameters and pollutants under similar weather and environmental conditions in a small area. Among meteorological and pollutant variables, only higher particulate matter concentrations correlated independently with intracerebral hemorrhage occurrence, while only ozone was independently associated with subarachnoid hemorrhage occurrence. These findings suggest the possibility that there are pathogenic associations between hemorrhagic stroke and meteorological factors and pollutants.

“…In contrast, Field and Hill [11] examined daily temperature changes caused by the Chinook winds and the incidence of SAH in the cold winter climate of Calgary, Canada and found no relationship. Rué et al [25] recently analyzed the influence of daily temperature variation on SAH occurrence in a homogeneous population of 236 SAH patients from a single facility in France; no relationship was observed between mean change in temperature and the occurrence of SAH. Finding a susceptible group, such as the elderly or people with a low socioeconomic status, who might be at increased risk of SAH, is essential.…”

The relationship between temperature and subarachnoid hemorrhage (SAH) is less studied than that between temperature and myocardial infarction or other cardiovascular diseases. This study investigated the association between daily temperature and risk of SAH by analyzing the hospital admission records of 111,316 SAH patients from 2004 to 2012 in Korea. A Poisson regression model was used to examine the association between temperature and daily SAH hospital admissions. To analyze data and identify vulnerable groups, we used the following subgroups: sex, age, insurance type, area (rural or urban), and different climate zones. We confirmed a markedly higher SAH risk only for people of low socioeconomic status in both hot and cold temperatures; the relative risk (RR) in the Medicaid group was significantly increased and ranged from 1.04 to 1.11 for cold temperatures and 1.10 to 1.11 for hot temperatures. For the National Health Insurance group, the RR was increased to 1.02 for the maximum temperature only. The increased risk for SAH was highest in the temperate zone. An increase above the heat threshold temperature and a decrease below the cold threshold temperature were correlated with an increased risk of SAH in susceptible populations and were associated with different lag effects and RRs.
