Soccer and Fédération Internationale de Football Association (FIFA) World Cup represent one of the world's biggest phenomena. Matches between national selections are viewed with great emotional involvement by the spectators. It is well documented fact that emotional stress can be a trigger of unwanted cardiovascular (CV) event. The aim of this retrospective study was to determine whether there has been an increase in the number of the emergency admissions for CV disease (CVD) in Emergency Room and Clinic for Cardiovascular Diseases in Clinical Hospital Centre Sisters of Charity during and after the period when Croatian national team played its matches on FIFA World Cup 2018 and to determine other parameters linked with that. The hospital's data base has been researched for the dates when Croatia played its matches and for the two following days in 2018. A control period was formed that included the same dates in 2017 and 2019. 1093 cases were assessed, out of which 398 were during the period of the World Cup. The incidence of CV admissions during that period was 1.15 (95% confidence interval [CI]; 1.02 to 1.31) times than during the control period. In this investigation was not observed statistically relevant increase for men, while for women there was a 1.30 (95% CI; 1.1 to 1.54) times higher incidence compared to the control period. Arrhythmias and angina pectoris are CV diseases that occurred significantly more often in the target period, and no difference was found between the target and control period in terms of disease outcome or CV risk profile. This study has shown that following Croatian national team's matches represented an additional risk for CV incident, especially for women.
