Heart Attack


The heart pumps blood and oxygen throughout the body, but it also depends on a supply of blood and oxygen to do its work. A heart attack happens when one of the arteries that bring blood to the heart muscle is blocked. A portion of the heart muscle is damaged or dies due to inadequate blood flow.

Signs Of A Heart Attack

The most common warning signals of a heart attack are:

  • Chest discomfort with lightheadedness, fainting, sweating, nausea or shortness of breath
  • Pain spreading to the shoulders, neck, arms or jaw
  • Uncomfortable pressure, fullness, squeezing, tightness, heaviness or pain in the center of the chest lasting more than a few minutes

Less common warning signs of heart attack include:

  • Nausea or dizziness
  • Palpitations, cold sweat or paleness
  • Shortness of breath and difficulty breathing
  • Stomach or abdominal pain; indigestion-like discomfort in the chest, especially with activity
  • Unexplained anxiety, weakness or fatigue

For women and diabetics, heart attack symptoms may be more subtle and tougher to identify. They are more likely to include:

  • Back or jaw pain
  • Nausea and/or vomiting
  • Sleeplessness
  • Unexplained or new onset shortness of breath
  • Unusual or unexplained fatigue

Many other conditions can cause chest pain, such as indigestion, panic attack or chest-wall or muscle pain from exercise. It is important to know that any of these symptoms can also be present with a heart attack. It's important to know the signs and symptoms of a heart attack, and act immediately by calling 9-1-1, even if you are not sure you're having a heart attack.
