Why is this important?

Beta blockers are a type of medicine that is used to lower blood pressure, treat chest pain (angina) and heart failure, and to help prevent a heart attack. Beta blockers relieve the stress on the heart by slowing the heart rate and reducing the force with which the heart muscle contracts (to pump blood). Most heart attack patients should be given a beta blocker within 24 hours of arriving 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.
