Cardiac arrest occurs when the heart stops and can no longer pump blood to the brain or vital organs. About 40 people each hour have a cardiac arrest while not in a hospital, and just over nine out of 10 do not survive, according to AHA statistics. Each year, more than 350,000 out-of-hospital cardiac arrests occur in the United States.

Where you live matters! People who live in African-American, Hispanic, and lower-income neighborhoods are more likely than others to die from a cardiac arrest. In fact, African-Americans and Hispanic cardiac arrest victims are also 30% less likely to have someone stop and perform CPR.
