Although many states require placement of automated external defibrillators (AEDs) at traditional exercise facilities, little is known about the relative frequency and survival from sudden cardiac arrest (SCA) at these sites and at alternative exercise facilities.
We performed a population-based cohort study of SCA from a heterogeneous metropolitan setting between 1/1/96 and 12/31/08, examining the location for SCA occurring at various indoor exercise facilities and comparing outcomes with SCA at other indoor public sites.
The most frequent activities performed at the time of SCA were (%): basketball (16), dancing (8.7), “working out” (8.7), treadmill (8), tennis (4.7), bowling (4), swimming (4) and weight-lifting (4). As per the table, survival to discharge from the hospital at exercise sites was 50% vs 36% for other indoor sites. Exercise site SCA was associated with younger age, male gender, and a higher likelihood of ventricular fibrillation, bystander CPR and AED placement.
SCA at exercise sites is associated with a remarkably high rate of survival, likely related to the following: physical condition of the victim, prompt bystander response (with CPR and AED) and initial rhythm of ventricular fibrillation. Furthermore, SCA occurs with relatively high frequency at alternative exercise sites such as dance studios and bowling alleys. These data have important public health implications for AED placement.
