Increase of out-of-hospital cardiac arrests in the male population of the French speaking provinces of Switzerland during the 1998 FIFA World Cup

Acute mental stress and anger are well known triggers of myocardial infarction and sudden cardiac death. It has been described in environmental disasters, such as earthquakes, or during military conflicts.1 The emotional intensity of sporting events and the behaviours associated with watching these events, such as smoking, binge drinking, and medical non-compliance, have also been shown to increase the rate of myocardial infarction and sudden cardiac death.2 However, recent observations showed a significant decrease in cardiovascular mortality in French men during the 1998 FIFA World Cup which was held in, and won by, France. This decrease was explained by a reduction of mental stress caused by the euphoria of victory.3 This competition was also an outstanding sporting event for neighbouring countries; according to FIFA data the total television audience of the 1998 World Cup was estimated at close to 10 million people in Switzerland. Taking into account the similarities in geographic situation, behaviour, and diet among populations of France and French speaking provinces of Switzerland (most of whom supported the French soccer team after the failure of the Swiss team to qualify for the final part of the competition), we were interested to know whether a decrease in out-of-hospital cardiac arrests (OHCA) would also be registered in Switzerland during this event.


The MICU (mobile intensive care unit) of the Swiss Emergency Cardiac Care system is qualified both for resuscitation of OHCA and to certify death, and is implicated in the quasi totality of the events. We retrospectively analysed MICU registers in the French speaking provinces of Switzerland (Geneva, Vaud, Fribourg, Neuchâtel), a population of 1.5 million inhabitants, during the 1998 FIFA World Cup (period B, 10 June 1998 to 12 July 1998) and during periods of the same duration preceding (period A, 8 May 1998 to 9 June 1998) and following (period C, 13 July 1998 to 14 August 1998) this competition. Only adult non-traumatic cardiac arrests of presumed cardiac origin were selected for our study. Statistics were calculated using Fisher’s exact test.


The main results of our study are presented in table 11.. It was found that 40% fewer OHCA were registered during the period preceding the FIFA 1998 World Cup (p  = 0.044) in comparison with the competition period; it was followed by a 60% (p  = 0.001) decrease of OHCA after the competition. There was no significant variation in the number of cardiac arrests in women (respectively seven, eight, and six patients suffered from OHCA before, during, and after the competition; p  = 0.96). However among males, 46% fewer OHCA (p  = 0.001) were registered during the period preceding the FIFA World Cup, in comparison with the period of competition, and a 68% (p  = 0.001) reduction of OHCA was noted during the period following the FIFA World Cup. Despite the fact that call to arrival intervals were short, only one fifth of patients were found in shockable rhythms. The OHCA long term survival rate was 6% in 1998.

In our study, an increase of OHCA among the male population of the French speaking provinces of Switzerland during the FIFA 1998 World Cup was noted. Recent observations by Berthier and colleagues, based on analysis of death certificates (recorded in French death statistics system), showed a decrease in cardiovascular mortality in French men the day that France won the 1998 FIFA World Cup. This decrease was attributed to a reduction in stress because of the euphoria of victory.3 This study and a study completed by Toubiana and colleagues did not find an increase in French cardiovascular mortality during the 1996 European football championship; this difference may be explained by different methods of observation, because of the limited value of death certificates in the diagnosis of OHCA as previously reported.4,5 The similarities in geographical situation, behaviour, and diet between the populations of the French speaking provinces of Switzerland and France led us to suppose that our results could be also obtained in France if our study were replicated using MICU data. Although we cannot prove that all patients of our study who suffered from OHCA were football supporters, the increase in mental stress can contribute to an increase in sympathetic nervous system stimulation and circulating catecholamines, and induce a state of hypercoagulability. In addition, increased alcohol and tobacco consumption, a decrease in physical activity, and medical non-compliance during major sporting events, such as the FIFA World Cup, could contribute to an increase in the rate of sudden cardiac deaths among the male population of the French speaking provinces of our country. On the basis of our observations and of previous studies which focused on the impact of soccer competitions on cardiovascular mortality, we recommend that general practitioners inform their patients, and members of their families, of the risk of myocardial infarction and sudden cardiac death, and to observe medical compliance during major sporting events. The reinforcement of the emergency cardiac care system (increased number of emergency phone operators, physicians and paramedics on call) before major sporting events could also be suggested. The low incidence of shockable rhythms, despite short call to arrival intervals, should also be mentioned. In light of this fact, programmes which improve emergency communication systems and lower the threshold for calls to first responder must be implemented. More information about practical measures to adopt in case of chest pain or cardiac arrest must be provided to the general public via the media and physicians before major sporting events. The changes in AED deployment strategies and development of public access defibrillation are also expected to reduce the incidence of sudden cardiac death.
