Coronary Artery Calcium Scoring (Heartscreen CT)
Coronary artery calcium scoring, also known as a heartscreen CT, is a specialized type of CT scan. During this heart screening CT scan, which takes about 20-30 seconds, the patient’s heart rate is monitored while the CT scanner acquires rapid images of the heart. Specialized software then uses the two pieces of information to construct high resolution image slices through the heart to visualize the coronary arteries.
The scans will show whether or not there is any calcification in the coronary arteries that supply blood and oxygen to the heart muscle. The presence of calcium in the coronary arteries is a reliable indicator of coronary artery disease which, if untreated, can progress to artery blockage and possibly to a heart attack. The data is analyzed by a radiologist using a specialized computer program that calculates the total amount of calcium present in the arteries and will give a comparison of where the patients’ coronary calcium level is relative to people of the same gender and age group. This information is then compiled into a report, which will be sent to you and your doctor.
The coronary artery calcium score is powerful predictor of future heart attack risk and can be a powerful motivator of health and lifestyle change for patients.

Reasons for Having Coronary Artery Calcium Scoring
A heartscreen CT is a cost effective means of evaluating the risk of coronary artery disease in patients who don’t have current symptoms of heart disease.
If you can say yes to two or more of the risk factors for heart disease, you may benefit from the information provided by a coronary artery calcium score. You and your physician can make better decisions regarding your health and lifestyle modifications to help reduce your risk of developing significant coronary artery disease. The test result can be a powerful motivator for change and can help guide you and your physician in selecting the most appropriate action.
Risks Involved in Coronary Artery Calcium Scoring
There is the risk of x-ray exposure; however, it is well below the level that causes adverse affects.
Conditions to Let Our Doctor Know About
In advance of your exam, let your Invision Sally Jobe radiologist or technologist know if any of the following circumstances apply to you:

- Previous heart surgery
- Pacemaker
- Inability to hold your breath for 30 seconds
- Inability to raise both hands above your head

If you have had a previous heartscreen CT, please let the imaging center staff know so they may obtain the previous coronary artery calcium score to compare with the current test results.
Insurance Coverage
