Heart attacks can be scary. They can be sudden, and they can be lethal. Recent statistics show that for every 100 people that suffered a heart attack outside the hospital, on average only 10 survived. But there’s another statistic from the American Heart Association that will give you hope — that improved to a 45% survival rate when a bystander performed CPR. This means that the more people understand how to respond, the better our survival rate from heart attacks will be.
