Coronary CT Angiogram

coronary ct angiogramA coronary CT angiogram is performed to evaluate the coronary arteries.  The coronary arteries extend from the aorta and supply the heart itself with blood.  These vessels are filled when the heart is relaxed.

The purpose of a coronary CT angiogram is to evaluate the coronary arteries to see if there is disease in the coronaries that has resulted in narrowing of the artery.  Coronary artery disease is is usually created by atherosclerosis.  This process occurs to some extent in all individuals, though it may be accelerated in those with high "cholesterol" levels (especially LDL).  The end result is the creation of a "plaque" or narrowing of the coronary artery.  If the coronary arteries become narrowed, the decreased blood flow to the heart may be felt as pain.  If the coronary arteries are completely blocked, a heart attack will occur.  If disease is present, you may be a candidate for an interventional procedure or surgery before an adverse outcome occurs.
