Coronary Artery Disease
Coronary artery disease, also called atherosclerosis, is the buildup of fatty deposits on the artery walls. The fatty deposits are also called plaques. Most plaques are composed of cholesterol. The artery can become partially blocked or narrowed, which reduces the flow of blood to the heart muscle. Reduced blood flow can cause chest pain, called angina pectoris, especially during physical activity or stress.
Angina Pectoris
Angina pectoris (also known just as angina) is a painful or uncomfortable feeling that can occur when the blood supply to your working heart muscle is decreased. You May Feel in or Near Your Chest:
• a heaviness • a tightness • a pressure • or burning sensation The Pain May also be Felt:
• in your shoulder • in your neck • in your throat • or along your jaw You May also Have:
• a tired feeling • nausea or indigestion • shortness of breath • sweating These are warning signs that your heart is not getting enough oxygen-rich blood, and are sign and symptoms of a heart attack. Heart Attack
A heart attack (also called a myocardial infarction) happens when the heart muscle does not get enough oxygen and nutrients and becomes damaged. The amount of damage depends on the location of the blockage and how long the muscle is without blood. Getting medical attention early helps to reduce the amount of damaged caused by a blockage.
