Correlation of Barometer Pressure and Incidence of Cerebrovascular Insult

Abstract

Introduction:The intention of this work is to research whether the link between the barometer pressure and the cerebrovascular insult (CVI) exists. The stroke is the first cause of non-traumatic disability and third illness by mortality in the majority of available relevant literature.Goals:Goal of the sudy was to research all the cases of the patients who suffered from the acute stroke in the Canton of Sarajevo and those who were treated in the pre-hospital phase by Emergency Medical Institute staff and their working diagnosis was established as CVI ac.Material and methods:The criteria in the research were established for inclusion and exclusion of cases. The days with and without CVI cases were compared with the meteorological data obtained from the Hydro-meteorological Institute of Federation of Bosnia and Herzegovina . Since the approval was requested and obtained from the Hydro-meteorological Institute, all the meteorological data could be compared. The meteorological data comprise the barometer pressure measuring every day at 7 h, 14 h and 21 h.Results and discussion:In the retrospective study, there will be followed, during three years (2004, 2005 and 2006), the cases of the patients who suffered from the stroke, and, the emergency medical care was offered to them by the side of the Emergency Medical Institute of Canton of Sarajevo staff. All the cases in the Canton of Sarajevo were followed regardless of the place of incidence: whether the help was offered in Institute’s outpatient departments, patient’s flat or at public place. Due to the extensiveness of data (in the analysis comprising three years, there was the total of 1930 cases), the test of normal distribution was used. Since it was about the pre-hospital research, the acute stroke was looked at generally without division by types. The certain diagnostics by types can only be established in the hospital.Conclusion:The results in the research indicate that the extreme values of barometer pressure, regardless of their being increased ones or decreased ones, influence the increase of CVI incidence, while by comparing the average values in the days with CVI and without CVI, they did not have any influence on the CVI incidence.

The Association between Meteorological Parameters and Aneurysmal Subarachnoid Hemorrhage: A Nationwide Analysis

“…Many institutional or regional retrospective studies have examined the relationship between climate and aneurysmal subarachnoid hemorrhage, but the findings in the literature have been inconsistent. Prior research has suggested that ambient temperature, precipitation, sunlight, average humidity, and the lunar cycle may all be associated with an increased risk of rupture of cerebral aneurysms [4] , [5] , [10] – [13] . On the other hand, others have found no associations between weather patterns and subarachnoid hemorrhage [3] , [8] , [9] .…”

Several Risk Factors for Aneurysmal Subarachnoid Hemorrhage

“…E. Slatina и соавт. изучали влияние атмосферного давления на все виды инсульта и выявили, что небольшие колебания атмосферного давления значимо не сказываются на повышении риска развития инсульта и только экстремально низкие или экстремально высокие изменения атмосферного давления сопряжены с риском нарушений мозгового кровообращения [18].…”
