Background: Psychological triggers such as emotional stress increase the incidence of acute cardiovascular events. The association between soccer championships and the risk of cardiovascular events are controversial. World Cup Soccer (WCS) involving the national team might be a trigger strong enough to induce cardiac arrhythmia. However, there are no reports which investigated the relationship between WCS and cardiac arrhythmia in the Japanese population.

Methods: We assessed 28 patients who were evaluated ischemic changes and/or arrhythmia by 24-hour Holter ECG during WCS 2014 in 4 Cardiology Divisions. The patients were divided into two groups [Watching group (n=10) patients who watched WCS on live-TV on June 20 (Japan vs. Greece) or July 25, 2014 (Japan vs. Colombia), and No-watching group (18 patients)]. The heart rates, arrhythmia, and ischemic changes were evaluated.

Results: There were no significant differences of clinical characteristics, heart rates, frequency of premature atrial contractions, and ischemic changes between the two groups. The frequency of premature ventricular contractions (PVCs) were significantly higher in the Watching group than in the No-watching group (2893±3657 vs. 237±472, P=0.005). Notably, the frequency of PVCs were significantly higher during live-TV in the Watching group than in the No-watching group (124±187 vs. 3.3±5.4, P=0.0003). No sustained ventricular tachycardia or fibrillation was recorded.

Conclusions: A significant association between watching WCS and the frequency of PVCs was observed. These data suggest that emotional stress while watching national team soccer matches may induce stress-related cardiovascular events.
