Why is this important?

The heart is a muscle that gets oxygen through blood vessels. Sometimes blood clots can block these blood vessels, and the heart can’t get enough oxygen. This can cause a heart attack. Chewing an aspirin as soon as symptoms of a heart attack begin may help reduce the severity of the attack. This chart shows the percent of heart attack patients who were given (or took) aspirin within 24 hours of arrival at the hospital.

Higher percentages are better.

Information about Heart Attack Care

A heart attack (also called an acute myocardial infarction) happens when the arteries leading to the heart become blocked and the blood supply is slowed or stopped. When the heart muscle can’t get the oxygen and nutrients it needs, the part of the heart tissue that is affected may die.

The symptoms of a heart attack can include:

• chest pain (often described as a crushing, squeezing or burning pain in the center of the chest and may radiate to your arm or jaw)
• shortness of breath
• dizziness faintness
• sweating
• nausea
• cold or clammy skin
• a gray or very ill appearance

Sometimes there may be no symptoms, especially if you have diabetes. Women sometimes have different symptoms, such as a different kind of chest pain and/or abdominal pain.
