What is a heart attack?

A heart attack happens when the flow of blood that brings oxygen to the heart muscle is significantly reduced or cut off completely. This is often a result of atherosclerosis, a process whereby the arteries narrow due to a buildup of plaque (fat, cholesterol, and other substances). Sometimes these plaques can break off, and blood clots can form around them. The clots in the coronary arteries then block blood flow to the heart, starving it of oxygen and nutrients (ischemia), causing damage or death to heart muscle. This damage to the heart muscle is a heart attack. Heart attack is medically termed myocardial infarction (MI).

What are the signs and symptoms of a heart attack in men and women?

Symptoms of a heart attack include:

  • Chest discomfort or pain that may feel like pressure or tightness
  • Squeezing, or fullness discomfort in one or both arms
  • Back, neck, jaw or stomach pain
  • Shortness of breath, which may or may not be accompanied by chest discomfort
  • Nausea
  • Palpitations
  • Lightheadedness
  • Sweating

Sometimes people having a heart attack experience no symptoms at all. The medical term for this is silent ischemia, commonly referred to as a "silent" heart attack.

If you think you are experiencing signs of a heart attack, call 911 immediately!

Are signs and symptoms of a heart attack different in women?

Women also experience chest pain and discomfort as a symptom of a heart attack. But women are more likely than men to experience other symptoms including shortness of breath, nausea and vomiting, and back or jaw pain. Sometimes the symptoms of a heart attack in women are more subtle, such as

  • pain in the upper abdomen
  • dizziness
  • lightheadedness or fainting
  • extreme fatigue

What are the signs and symptoms of heart disease (cardiovascular disease)?

  • Shortness of breath
  • Heart palpitations
  • Pain in the neck, jaw, throat, back, or upper abdomen

What can you do if you are alone and think you are having a heart attack?

If you have a heart attack and are home alone when it occurs here are some tips help improve your outcome.

  • Know the symptoms of a heart attack. Keep your cell phone available at all times. If you suspect you are experiencing symptoms of a heart attack, call 911 immediately. Minutes count! Do this FIRST, before anything else.
  • If the 911 operator suggests it, take an aspirin if you are not allergic. Be prepared  talk to your doctor and find out if you should be on aspirin therapy to prevent a heart attack before it occurs.
  • The Internet has spread the idea of "cough CPR," however, the American Heart Association does not endorse this as a way to prevent heart attacks. If you are having a sudden abnormal heart rhythm (arrhythmia) and are conscious you may be able to cough forcefully enough to maintain enough blood flow to the brain to stay conscious a few seconds more until the arrhythmia breaks. Coughing probably won't hurt, but always call 911 first.
