What is Myocardial Infarction?

Commonly known as a heart attack, Myocardial Infarction, occurs when blood flow stops to a part of the heart causing damage to the heart muscle.

A heart attack happens when the flow of oxygen-rich blood to a section of heart muscle suddenly becomes blocked and the heart can’t get enough oxygen. If blood flow isn’t restored quickly, the section of heart muscle begins to die.

Heart attacks most often occur as a result of Coronary Artery Disease, a condition in which a waxy substance called plaque builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart. 

When plaque builds up in the arteries, the condition is called Atherosclerosis. The buildup of plaque occurs over many years. 

Eventually, an area of plaque can rupture inside of an artery. This causes a blood clot to form on the plaque's surface. If the clot becomes large enough, it can mostly or completely block blood flow through a coronary artery.

If the blockage isn't treated quickly, the portion of heart muscle fed by the artery begins to die. Healthy heart tissue is replaced with scar tissue. This heart damage may not be obvious, or it may cause severe or long-lasting problems.

Many people aren't sure what's wrong when they are having symptoms of a heart attack. Some of the most common warning symptoms of a heart attack for both men and women are:

  • Chest pain or discomfort. Most heart attacks involve discomfort in the center or left side of the chest. The discomfort usually lasts more than a few minutes or goes away and comes back. It can feel like pressure, squeezing, fullness, or pain. It also can feel like heartburn or indigestion.
  • Upper body discomfort. You may feel pain or discomfort in one or both arms, the back, shoulders, neck, jaw, or upper part of the stomach (above the belly button).
  • Shortness of breath. This may be your only symptom, or it may occur before or along with chest pain or discomfort. It can occur when you are resting or doing a little bit of physical activity.
  • Breaking out in a cold sweat
  • Feeling unusually tired for no reason, sometimes for days (especially if you are a woman)
  • Nausea (feeling sick to the stomach) and vomiting
  • Light-headedness or sudden dizziness
