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.
Who's At
Risk?
Heart attacks strike both men and women. However, some persons are more likely than others to
have a heart attack because of their "risk factors." Risk factors are behaviors or conditions that increase the
chance of a disease. Some of the risk factors for heart attack are beyond your control, but most can be modified to
help you lower your risk of having a first–or repeat–heart attack.
Factors that increase the risk of a heart attack are:
Factors you cannot
control
Pre-existing coronary heart diseases, including a previous heart attack, a prior angioplasty
or bypass surgery, or angina
Age-In men, the risk increases after age 45; in women, the risk increases after age 55.
Family history of early heart disease-a father or brother diagnosed before age 55; or a
mother or sister diagnosed before age 65.
Factors you can
control
Smoking.
High blood pressure.
High blood cholesterol.
Overweight and obesity.
Physical inactivity.
Diabetes.
Risk factors do not add their effects in a simple way. Rather, they multiply each other’s
effects. So, it is very important to prevent or control risk factors that can be modified. If you have one or more
of these factors, see your health care provider to find out how to reduce your risk of having a first or repeat
heart attack.
Frequently Asked Questions About Heart Attack
Heart Attack Warning Signs—
Q: How would I know if I were having a heart attack?
Often, it is not easy to tell. But there are symptoms people may have. These are:
an uncomfortable pressure, squeezing, fullness, or pain in the center of the chest that lasts more than a few
minutes, or goes away and comes back; discomfort in other areas of the upper body, which may be felt in one or
both arms, the back, neck, jaw, or stomach; shortness of breath, which often occurs with or before chest
discomfort; and other symptoms such as breaking out in a cold sweat, nausea, or light-headedness. When in doubt,
check it out! Call 9-1-1. Don’t wait more than a few minutes–5 at most. Call right away!
Q: What is angina and how is it different from a heart attack?
An episode of angina is NOT a heart attack. However, people with angina report
having a hard time telling the difference between angina symptoms and heart attack symptoms. Angina is a
recurring pain or discomfort in the chest that happens when some part of the heart does not receive enough blood
temporarily. A person may notice it during exertion (such as in climbing stairs). It is usually relieved within
a few minutes by resting or by taking prescribed angina medicine. People who have been diagnosed with angina
have a greater risk of a heart attack than do other people.
Prehospital Delay Time—
Q: I’d rather wait until I’m sure something’s really wrong. What’s the rush anyway?
Clot-busting drugs and other artery-opening treatments work best when given
within the first hour after a heart attack starts. The first hour also is the most risky time during a heart
attack–it’s when your heart might stop suddenly. Responding fast to your symptoms really increases your chance
of surviving.
Q: So how quickly should I act?
If you have any heart attack symptoms, call 9-1-1 immediately. Don’t wait for
more than a few minutes–5 at most–to call 9-1-1.
Q: Why should I bother? If I’m going to die, there’s not much I can do about it anyway, is
there?
That’s not true. There is something that can be done about a heart attack.
Doctors have clot-busting drugs and other artery-opening procedures that can stop or reverse a heart attack, if
given quickly. These drugs can limit the damage to the heart muscle by removing the blockage and restoring blood
flow. Less heart damage means a better quality of life after a heart attack.
Given that these new therapies are available, it’s very sad to know that so many
people cannot receive these treatments because they delay too long before seeking care. The greatest benefits of
these therapies are gained when patients come in early (preferably within the first hour of the start of their
symptoms).
The Role of Emergency Medical Personnel—
Q: Emergency medical personnel cause such a commotion. Can’t I just have my
wife/husband/friend/coworker take me to the hospital?
Emergency medical personnel—also called EMS, for emergency medical services—bring
medical care to you. For example, they bring oxygen and medications. And they can actually restart someone’s
heart if it stops after they arrive. Your wife/husband/friend/coworker can’t do that, or help you at all if they
are driving. In the ambulance, there are enough people to give you the help you need and get you to the hospital
right away.
Steps to Survival—
Q: I’m not sure I can remember all this. What can I do to make it easier for me?
You can make a plan and discuss it in advance with your family, your friends,
your coworkers and, of course, your doctor. Then you can rehearse this plan, just like a fire drill. Keep it
simple. Know the warning signs. Keep information–such as what medications you’re taking–in one place. If you
have any symptoms of a heart attack for a few minutes (no more than 5), call the EMS by dialing 9-1-1 right
away.
Q: I carry nitroglycerin pills all the time for my heart condition. If I have heart attack
symptoms, shouldn’t I try them first?
Yes, if your doctor has prescribed nitroglycerin pills, you should follow your
doctor’s orders. If you are not sure about how to take your nitroglycerin when you get chest pain, check with
your doctor.
Q: What about taking an aspirin like we see on television?
You should not delay calling 9-1-1 to take an aspirin. Studies have shown that
people sometimes delay seeking help if they take an aspirin (or other medicine). Emergency department personnel
will give people experiencing a heart attack an aspirin as soon as they arrive. So, the best thing to do is to
call 9-1-1 immediately and let the professionals give the aspirin.
