Objective: Psychological triggers, such as emotional stress, increase the incidence of acute cardiovascular events. The association between soccer championships and risk of cardiovascular events remains controversial. A World Cup Soccer (WCS) match involving a national team might be a strong enough trigger to induce cardiovascular events. However, there are no reports of a multicenter study that has investigated the relationship between watching WCS and cardiac arrhythmia.
Methods: We assessed 25 patients who were evaluated for ischemic changes and/or arrhythmia using 24-h Holter electrocardiography in four cardiology divisions during WCS 2014. The patients were divided into two groups: the watching (W) group consisted of 7 patients who watched WCS on live television and the Non-Watching (NW) group consisted of 18 patients who did not watch WCS. Heart rates, arrhythmia, and ischemic changes were evaluated.
Results: There were no differences in the clinical characteristics, heart rates, premature atrial contraction frequencies, and ischemic changes between the two groups. Although there were no differences in total Premature Ventricular Contractions (PVCs), the frequency of PVCs during matches (61 ± 101 vs. 7 ± 8, P = 0.03) and 1 hour before matches (15 ± 17 vs. 3 ± 5, P = 0.01) were significantly higher in the W group than in the NW group. No sustained ventricular tachycardia or fibrillation was observed.
Conclusions: A significant association between watching WCS and frequency of PVCs was observed in patients with/or suspected of having cardiovascular disease.
