Hundreds of deaths from coronary heart disease occur outside a hospital daily, according to OSHA, but up to 60 percent of those deaths could have been prevented if automated external defibrillators (AEDs) had been immediately available.

Each year, about 600,000 Americans – one in four deaths -- in the United States are from heart disease, according to the Centers for Disease Control and Prevention (CDC). Of the 715,000 Americans who have a heart attack each year, about 525,000 are first-timers, says the CDC, and those individuals may not know what’s happening.
