About Heart Attack (Myocardial Infarction)

High blood pressure, elevated cholesterol or smoking can damage the inner lining of arteries in the body. This leads to a build up of fatty substances and calcium called plaque. This may slow the flow of blood to the heart muscle and begin coronary artery disease or peripheral vascular disease. If this buildup continues, blood flow to the heart muscle is severely decreased, and less oxygen is brought to the heart. This lack of oxygen to the heart muscle may cause a range of sensations called angina: burning, numbness, pressure to severe pain in the chest, arms, jaw, throat or upper back.

A heart attack (myocardial infarction) may occur if the blood flow is blocked by a blood clot in the narrowed artery. Without blood flow carrying oxygen, the heart muscle (myocardium) in the area becomes permanently damaged.


Heart attack signs or symptoms may include:

  • Chest discomfort: Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes, or that goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness or pain.
  • Discomfort in other areas of the upper body: Symptoms can include pain or discomfort in one or both arms, the back, neck, jaw or stomach.
  • Shortness of breath: May occur with or without chest discomfort.
  • Other signs: These may include breaking out in a cold sweat, nausea or lightheadedness.

Risk Factors & Prevention

According to the American Heart Association, heart attack prevention should begin by age 20. To prevent cardiovascular disease monitoring your risk factors is key. If you are over the age of 40 or have multiple risk factors, it's important to establish a cardiovascular prevention plan. A first-time heart attack or stroke can be fatal, so prevention is critical to improve your lifelong health and well being.
