Heart Attack

It’s one of the major causes of death in the U.S. A heart attack (also known as myocardial infarction) occurs when blood flow to a section of heart muscle becomes blocked, preventing it from receiving the oxygen it needs. Unless it’s treated quickly, the muscle may become damaged and die.

Heart Attack Symptoms

The signs and symptoms of heart attacks can vary from person to person. They include:

  • Pressure, fullness, or a squeezing discomfort in the center of the chest. This discomfort may reach to the shoulders, arms, jaw, and back, and can last for more than a few minutes. (Angina, which has similar symptoms, goes away with rest.)
  • Shortness of breath
  • Sweating
  • Lightheadedness, weakness, possibly even fainting
  • Nausea and vomiting
  • Impending sense of doom

When in Doubt, Call 911.

A heart attack is a serious and often fatal condition. If you think you or someone with you is experiencing a heart attack, you should seek medical attention immediately by dialing 911. If the blood flow can be restored in time, damage to the heart can be limited or prevented
