If you’re going to have a heart attack (and hopefully you’re not), your best bet is to do it at the gym. A recent study published in the Journal of the American College of Cardiology found that people experiencing sudden cardiac arrest at dedicated fitness facilities had a greater chance of surviving than those at other indoor venues, most likely because of the greater presence of automated external defibrillators at gyms as well as the capabilities of fitness club employees to perform CPR. The study looked at sudden cardiac arrests in the Seattle area between 1996 and 2008 and found that 56 percent of people who suffered heart attacks at health clubs and fitness centers lived, while only 45 percent and 34 percent survived at alternative fitness facilities (i.e., bowling alleys and dance studios) and non-exercise facilities (retail stores, restaurants, etc.), respectively. The take-home of this study is simple: AEDs and CPR-certified employees should be present at more businesses, whether their patrons will be exercising intensely or not.
