Abstract
Aim: In this study, we investigated a relationship between stroke and weather, humidity, wind speed, pressure, and temperature.
Materials and Methods: This study has been performed at Çanakkale Onsekiz Mart University Faculty of Medicine emergency service, and Çanakkale State Hospital emergency service between January 2012 to December 2014 with non-traumatic patients diagnosed with ischemic or hemorrhagic stroke. The study is done retrospectively. We recorded patients’ age, sex, history of chronic disease, white blood cells, hemoglobin, hematocrit, platelet, red cell distribution width, mean platelet volume, urea, creatinine, sodium, potassium, percentage of lymphocytes, percentage of neutrophils, stroke type, atrial fibrillation, the 30-day mortality retrospectively in hospitals automation systems The average daily temperatures and atmospheric pressure, humidity, wind speed, and direction; has been taken and analyzed from the Ministry of Forestry and Water Affairs General Directorate of Meteorology. The statistical analysis was made with Chi-square and Pearson correlation test.
Results and Conclusion: A total of 1397 patients were studied retrospectively. The mean age of men was 69.89 ± 12.96 and the mean age of women was 75.62 ± 11.8. The mean age of women to have a stroke was found to be statistically significantly higher than that of males. When the cases were analyzed depending on the season, there was a significant increase in summer and autumn. In the cases that had a stroke, the most frequent risk factor was found to be hypertension. For patients with a history of cerebrovascular disease than any other chronic disease; mortality was significantly better. For patients who died within 1 month; white blood cell values were significantly higher compared to survivors. Men’s stroke patients' hemoglobin and creatinine values were significantly higher. Pressure and wind speed parameters showed no association between stroke types, but the incidence of ischemic stroke increased at higher temperature levels and lower humidity values.
