The bleeding weather: association of environmental changes with intracranial aneurysms’ rupture
摘要
Various studies have attempted to link aneurysmal subarachnoid hemorrhage (aSAH) with environmental factors, yielding inconsistent results.
MethodsWe retrospectively collected clinical and demographic data from all patients who presented to our hospital with aSAH between January 1st, 2015, and December 31st, 2021.
ResultsOur study found a significant variation in the occurrence of aneurysm ruptures based on the day of the week, with more ruptures occurring on Mondays compared to Fridays. Additionally, we discovered that the amount of dust in the air prior to the ictus influenced the severity of the aSAH. In contrast, other environmental parameters such as atmospheric pressure, temperature, humidity, rain, wind speed, and cloud cover did not significantly impact the prevalence or severity of aSAH.
ConclusionsTo our knowledge, this is the first study to associate the severity of aSAH with atmospheric dust levels. Another key finding is the increased incidence of aneurysm ruptures on Mondays compared to Fridays.
