Introduction: The growing recognition of environmental factors that play a crucial role in the incidence of Out-of-hospital cardiac arrests (OHCA) has been reflected in various research studies.Hypothesis: Our goal was to explore the links between various weather conditions and the frequency of OHCA in Hungary from November 1, 2018, to April 25, 2022.Methods: We conducted a comprehensive analysis using data from the Hungarian National Ambulance Service and weather records. T-tests were employed for normal distributions, and Mann-Whitney tests were used in other instances. A significance level of 0.05 was applied in both cases.Results: We observed a noticeable rise in OHCA incidents during periods of extreme cold (average daily temperature (T) below 0 °C) and extreme heat (average daily T over 25 °C). Instances of OHCAs were significantly higher on days with rapid T changes (intraday T shift above 5 °C), with a p-value of 0.013. The frequency of OHCA cases also saw a notable increase on frontal days compared to non-frontal days. However, we found no significant correlation between precipitation and OHCA cases.Conclusions: In conclusion, our analysis found significant associations between extreme cold and heat, and rapid T changes with the incidence of OHCA, while frontal days and precipitation did not reach statistical significance.Climate Change National Laboratory RRF-2.3.1-21-2021
