Most often, angina is chronic, caused by a limited blood supply due to narrowing of the coronary arteries that supply the heart muscle. The divisions of the aorta are abdominal aorta, thoracic aorta, aortic artery and ascending aorta. The arteries carry the oxygenated blood from the right and left ventricles of the heart to all parts of the body.
Artery walls become thick and lose their ability to stretch.
These deposits decrease the width of the artery. Cholesterol contributes to the fatty deposits in atherosclerosis. These fats tend to lower both good and bad cholesterol and should be used in very small amounts. These fats tend to raise blood cholesterol levels. Sodium is needed for the squeezing of the heart and other muscles and for delivery of nerve impulses.
