AIM: The relationship between watching major sporting events and cardiac hospital admissions is contentious. This study is the first to investigate cardiovascular admissions during Rugby World Cup (RWC) tournaments.
METHODS AND RESULTS: New Zealand (NZ) public hospital admissions data were analysed for cardiovascular events during the 1999, 2003, 2007 and 2011 RWC tournaments. The exposure period was the day of the NZ All Blacks last match and 2 days post-match. The control period was equivalent days in October or November for 3 years prior to or after each RWC. The NZ 2011 semi-final win and 2000 Olympics opening ceremony were also analysed. There were 281 ± 14 and 3313 ± 379 cardiac admissions in the exposure and control periods. The semi-final loss in 2003 was associated with a 50% (p < 0.01) increase in pooled heart failure admissions and a 20% (p < 0.05) increase in pooled acute coronary syndromes admissions. Increases in heart failure were specific to women with a two-fold increase on match day and 2-days post (p < 0.01). There was no increase in male heart failure admissions but arrhythmias increased 2.6 times (p < 0.01) 1-day after losing the 2003 semi-final. In contrast, admissions were typically lower after the 2011 semi-final win and Olympics opening ceremony.
CONCLUSION: This is the first study to find a relationship between hospital admissions for heart failure in women and a major sporting event. Preventive health measures should be considered in fans with cardiovascular disease or at high risk of cardiovascular events during sporting events. Winning or losing does matter.
