Abstract


This study presents the results of a retrospective analysis of the challenges of patients with atrial fibrillation (AF) for ambulance medical care depending on weather conditions and season. Aim. This study aimed to evaluate the effect of meteorological factors on addressing of patients with AF for emergency medical care in the context of seasonal dynamics. Materials. Archival cards of ambulance calls in the winter, spring, and summer 2012 and the corresponding databases of average daily meteorological parameters, day-to-day changes (∆), and pathogenicity indices were used: air temperature (it), atmospheric pressure (iр), humidity (ih), wind speed (iv), cloudiness (in), and general weather pathogenicity index (IWP). Results. In winter, the most significant negative effect is caused by fluctuations in meteo-factors: average daily air temperature and atmospheric pressure, it, ∆p, IWP; in spring were the average daily air temperature and atmospheric pressure, it, i∆t; in summer was i∆t. The response of the population to AF for medical care in the winter (6.7 ± 0.5 person/day) and spring (6.9 ± 0.4 person/day) is higher than that in summer (5.2 ± 0.5 person/day). Conclusion. The maximum number of correlation links between the frequency of ambulance medical care calls and meteorological factors is present in the winter and spring and has gender and season specifics. Seasonality factor affects the treatment of patients with AF for emergency medical care.
