A CT Angiogram is a test that uses powerful x-ray technology to view your heart and surrounding arteries. This test detects any calcified plaque that is building up and assigns a calcium score. The presence of building plaque can be a sign of Coronary Artery Disease (CAD) which puts you at an increased risk of having a heart attack.
The test is non-invasive, and unlike a traditional angiogram it does not require catheter insertion through the groin.
Your doctor may order this test if:
- there are suspected blockages in your arteries
- you are at an increased risk of CAD or have other heart problems
- you have certain heart conditions that make a traditional angiogram too risky
How To Prepare:
- Your doctor will give you specific instructions prior to the test.
- You may be asked to fast for several hours before your appointment.
