Traditional exercise centers more likely to have AEDs, leading to reduced death rates
People experiencing sudden cardiac arrest at exercise facilities have a higher chance of survival than at other indoor locations, likely due to early CPR and access to an automated external defibrillator (AED), among other factors, according to a study published online today in the Journal of the American College of Cardiology. The findings underscore the importance of having AEDs in places where people exert themselves and are at greater risk of sudden cardiac arrest.
Previous studies have shown that regularly exercising greatly reduces a person's overall risk of sudden cardiac arrest; however, during and immediately following exercise the risk of sudden cardiac arrest is slightly higher. Because AEDs have been proven to save lives when used quickly after sudden cardiac arrest, they are often placed in health clubs and gyms. Less is known about the frequency of sudden cardiac arrest at other indoor locations where exercise takes place-such as bowling alleys, dance studios or community centers -- but AED placement is less common.
This study looked at the frequency, treatment and outcomes of sudden cardiac arrest at both traditional and alternative exercise facilities. Researchers looked at 849 sudden cardiac arrests that occurred at public indoor facilities in Seattle and King County, Wash., from 1996-2008.
Location of the sudden cardiac arrest was categorized as occurring at a traditional exercise facility (health clubs, fitness centers), an alternative exercise facility (bowling alleys, workplace or hotel gyms, dance studio) or a non-exercise facility (banks, restaurants, shopping centers, airports).
In total, 52 sudden cardiac arrests occurred at traditional exercise facilities, 84 at alternative exercise facilities and 713 at non-exercise facilities. Survival rates were 56 percent, 45 percent and 34 percent, respectively. Where information was available on the activity at the time of arrest, in 77 percent of cases the sudden cardiac arrest occurred during exercise, with only 18 percent occurring after exercise and 4 percent before exercise.
