Major regional disparities in outcomes after sudden cardiac arrest during sports

Abstract

Major regional disparities exist in survival rates (up to 10-fold) after SCA during sports. SCA cases from regions with the highest levels of bystander resuscitation had the best survival rates to hospital admission and discharge.

Characteristics and Outcomes of Sudden Cardiac Arrest During Sports in Women

“…Consistent with this observation, the incidence of SCDs in women has been described as being transiently elevated during moderate-to-vigorous exertion but with an RR of only 2.38 (95% CI, 1.23 to 4.60), whereas being almost 20-fold higher (RR, 44.9; 95% CI, 26.7 Data are number (%), unless otherwise specified. Data were missing on presence of witness (4), monitored rhythm (12). Percentages were calculated on the basis of the total number of known events.…”

“…4,11,12 Briefly, this 5-year prospective study was performed according to Utstein guidelines, in France between April 2005 and April 2010. To the best of our knowledge, this registry is the first prospective national database offering a complete overview of SCD during sports, including cases from recreational as well as competitive sports.…”

A Clinical Perspective on Sudden Cardiac Death

“…8,[14][15][16] Although the vast majority of such cases occur during middle age, they represent a relatively small proportion (5 %) of overall sudden cardiac arrest cases. 17 The sports-related sudden death rate is higher in elite athletes, with a reported incidence of 1:8,253 participants per year in the National Collegiate Athletic Association (NCAA).…”

“…71 Survival is better in places with facilities for bystander resuscitation. 15 Defibrillators in public locations (Table 4), such as train stations, 13 however, only reduce the incidence of SCD when the local population is trained to use them. 72 Recent data from the United States Cardiac Arrest Registry to Enhance Survival (CARES) suggest that rates of survival following out-of-hospital cardiac arrest have improved among sites participating in a performanceimprovement registry.…”

Effectiveness of cardiac arrest prevention during exercise

“…Sudden cardiac arrest (SCA) during exercise is a rare event [1][2][3][4][5][6][7] , with an incidence of between 0.4 and 6.4 per 100,000 person-years 4) , but it is a devastating event with as low a survival-to-hospital-discharge rate as 5% 8) . Various exercise types cause SCA, though low-intensity exercise might have a lower incidence of SCA than highintensity competitive sports 9) .…”
