The heart is a muscle that receives 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.
Why this is important:
Aspirin can help keep blood clots from forming and dissolve blood clots that can
cause heart attacks.
This chart above shows the percent of heart attack
patients who were given (or took) aspirin within 24 hours of arrival at the hospital.
