CT Angiogram Heart

A CT angiogram of the heart is primarily performed to look at the blood vessels of the heart.  The vessels of the heart are known as coronary arteries.  The coronary arteries extend from the aorta (see aorta CTA) and supply the heart itself with blood when the heart is relaxed.

The purpose of a CT angiogram heart is to evaluate the arteries of the heart and determine if there is  narrowing of the artery.  Heart disease is is usually created by atherosclerosis, and a CT angiogram heart can demonstrate how much buildup there is inside the arteries. 

Atherosclerosis 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 seen on a CT angiogram heart, your cardiologist may suggest that you undergo an interventional procedure or surgery to open up the heart vessel.

A CT angiogram heart carries significant risks and potential side effects.  The main side effects of a CT angiogram include radiation and contrast exposure.  You should speak with your physician to determine if you are a candidate for a heart CT angiogram.  Your physician will determine if the risks outweigh the benefits of potentially diagnosing a narrowed coronary artery.
