[The effect of alternating meteorological parameters on fatally ruptured aortic aneurysms (autopsy-based data)]. / Meteorológiai paraméterek változásának hatása a halálos kimenetelu aortaaneurysma-rupturákra.

INTRODUCTION: There are several statements about the connection between cardiovascular diseases and climate change. On behalf of our observation-based knowledge we hypothesized a relationship between the occurence of aortic aneurysm (AA) rupture and weather changes. AIM: The purpose of our study was to explore the relationship between fatal aortic catastrophe and changes in atmospheric pressure and temperature. By using a new method we could even measure the intensity of the connection. METHOD: We have developed a software earlier to examine the link between pulmonary embolism mortality and the weather on data sets comprised of aortic aneurysm cases, where the medical condition had led to the fatal rupture of the aorta. For the events mentioned earlier we used the autopsy database of Semmelweis University between January 1, 2005 and January 1, 2014. Altogether we examined 152 aneurysm-related aortic catastrophes. We reported the exact day of the incident and the weather conditions on that day and the day before. RESULTS AND CONCLUSION: We have defined that the occurrence rate of fatal aortic catastrophe showed a slight dependence on the two examined parameters within our groups. We have found the connection related to ruptured aortic aneurysm and changes in atmospheric pressure more significant than their connection with mean daily temperatures. With the increase in atmospheric pressure, the rate of AA mortality also increased. In the knowledge of our results we believe that the mathematical model we used can be an effective starting point for population-based and prospective studies. Orv Hetil. 2018; 159(37): 1501-1505.
