Heart attack means the heart has stopped pumping blood.
It is the leading cause of death in adults. But, if you know the symptoms and what to do first if heart attack strikes, you may be able to save the life of a friend, coworker, or loved one. With CPR training, older children and adults alike may be able to help a heart attack victim. A heart attack can happen anytime, and within 4-6 minutes death or serious damage can take place. But, someone trained in CPR can greatly improve the victim's chances of surviving a heart attack.
