Each year, approximately 300,000 people in the U.S. die from sudden cardiac arrest (SCA)
The risk of sudden death is highest soon after a heart attack, yet SCA is often the first sign of heart disease. In fact, 50% of males and 64% of females who experience SCA report no prior symptoms of heart disease.
With every minute that passes without a shock to the heart, an SCA victim’s chance of survival decreases by 7-10%. After 10 minutes, very few SCA victims survive.
