What is Coronary CTA?
Coronary CTA is a dramatic breakthrough in heart attack prevention and risk assessment. Within the space of 15-20 minutes, it can accurately assess the health of your coronary arteries. Coronary CTA is a non-invasive means of seeing the interior of the coronary arteries and can discover signs of heart disease not shown on an EKG, stress test, calcium scoring or even cardiac catheterization. It is also safer, less invasive and more cost-effective than cardiac catheterization. Coronary CTA is a procedure so advanced that only a handful of practices in the country hold the experience, expertise, and technology to provide it. Fortunately, we are one of them: Chattanooga Imaging is the only diagnostic imaging center in the region currently providing CCTA exams.
Who should have a Coronary CTA?
If you have one or more of the following risk factors, you may be a candidate for Coronary CTA.
- High Blood Pressure
- High Cholesterol
- Family History of Heart Disease
- High Stress
- Sedentary Lifestyle
What to Expect?
You will arrive on the day of your Coronary CTA and will be taken to our monitoring area where you will be given a Beta Blocker (an oral medication that will reduce your resting heart rate) and an IV will be inserted into a vein in your arm. After about an hour, you will be taken to the CT scan room, where you will be asked to lie on a table and your examination will begin. Intravenous contrast will be administered during the study. You will hear the CT x-ray tube will rotating around the table, taking pictures from all angles and you will be asked to hold your breath for short periods of time. The entire study takes about 15 minutes. The images taken will then be analyzed and interpreted by our Board Certified radiologist. A CD of your images, as well as a report will be provided to you and your referring physician.
Do not consume any form of caffeine 12 hours prior to the study. Do not eat any solid foods 4 hours prior to the study. Drink two 8 ounce glasses of water 1 hour before the study.
