<u>Answer:</u>

<em><u>MEANING</u></em>

<em>A heart attack is a medical emergency. A heart attack usually occurs when a blood clot blocks blood flow to the heart. Without blood, tissue loses oxygen and dies. </em>

<em>A heart attack occurs when one or more of your coronary arteries become blocked. Over time, a coronary artery can narrow from the buildup of various substances, including cholesterol (atherosclerosis). This condition, known as coronary artery disease, causes most heart attacks.</em>

<em><u>CAUSES:</u></em>

<em>Chest Pain, Pressure, Fullness, or Discomfort. </em>

<em>Discomfort in other areas of your body. </em>

<em>Difficulty breathing and dizziness.  </em>

<em>Nausea and cold sweats. </em>
