Coronary computed tomography angiography (CTA) is recommended when the
cardiac CT calcium scoring results are greater than 0. The Coronary CTA is the gold standard heart
imaging test that helps determine if plaque buildup has narrowed the coronary
arteries which supply blood to the heart. Unlike the non-invasive cardiac
CT calcium scoring test, with a coronary CTA scan you will receive an
iodine-containing contrast material as an intravenous (IV) injection to
ensure the best possible images of the heart blood vessels.
Why would I have this test?
You physician or cardiologist may recommend the coronary CTA if you have:
- suspected abnormal anatomy of the coronary arteries
- low or intermediate risk for coronary artery disease, including patients
who have chest pain and normal, non-diagnostic or unclear lab and ECG results
- low to intermediate risk atypical chest pain in the emergency department.
- non-acute chest pain
- new or worsening symptoms with a previous normal stress test result
- unclear or inconclusive stress test results
- new onset heart failure with reduced heart function and low or medium risk
for coronary artery disease
- intermediate risk of coronary artery disease before non-coronary cardiac surgery
- coronary artery bypass grafts
What are the benefits of a coronary CTA test?
A coronary CTA uses advanced CT technology to obtain 3D images of the moving
heart and vessels. Apart from identifying coronary artery narrowing as
the cause of chest discomfort, it can also detect other possible causes
of symptoms, such as a collapsed lung, blood clot in the vessels leading
to the lungs, or aortic abnormalities. Your primary care physician or
cardiac specialist, in consultation with a radiologist who would perform
the test, will determine whether a coronary CTA is appropriate for you.
