Heart Attacks
Coronary heart disease (CHD) is the leading cause
of death for both men and women in the United States.
CHD is caused by a narrowing of the coronary arteries
that supply blood to the heart, and often results
in a heart attack.
Each year, about 1.1 million Americans suffer a heart
attack. About 460,000 of those heart attacks are fatal.
About half of those deaths occur within 1 hour of
the start of symptoms and before the person reaches
the hospital.
Fortunately, everyone can take steps to protect their
heart–and their life or that of someone else.
The key is seeking medical care as soon as possible.
This Web page tells you about heart attack and the
steps you can take to increase your chances of survival.
You’ll learn why a fast response to the signs
of a heart attack is crucial to save lives and limit
heart damage.
