CORONARY ARTERY CALCIUM QUANTIFICATION IN CONTRAST-ENHANCED COMPUTED TOMOGRAPHY ANGIOGRAPHY by ABINASHI DHUNGEL Under the Direction of Dr. Michael Weeks ABSTRACT Coronary arteries are the blood vessels supplying oxygen-rich blood to the heart muscles. Coronary artery calcium (CAC), which is the total amount of calcium deposited in these arteries, indicates the presence or the future risk of coronary artery diseases. Quantification of CAC is done by using computed tomography (CT) scan which uses attenuation of x- ray by different tissues in the body to generate three-dimensional images. Calcium can be easily spotted in the CT images because of its higher opacity to x-ray compared to that of the surrounding tissue. However, the arteries cannot be identified easily in the CT images. Therefore, a second scan is done after injecting a patient with an x-ray opaque dye known as contrast material which makes different chambers of the heart and the coronary arteries visible in the CT scan.

  • Coronary Artery Calcium Scoring – Position Statement
    The Cardiac Society of Australia and New Zealand Coronary Artery Calcium Scoring – Position Statement Development of this position statement was coordinated by Christian Hamilton-Craig (co-chair), Gary Liew (co-chair), Jonathan Chan, Clara Chow, Michael Jelinek, Niels van Pelt and John Younger. No authors have any relevant Conflict of Interest to disclose. It was reviewed by the Quality Standards Committee and ratified at the CSANZ th Board meeting held on Friday, 26 May 2017. Coronary Artery Calcium Scoring (CAC) is a non-invasive quantitation of coronary artery calcification using computed tomography (CT). It is a marker of atherosclerotic plaque burden and an independent predictor of future myocardial infarction and mortality. CAC provides incremental risk information beyond traditional risk calculators (eg. Framingham Risk Score). Its use for risk stratification is confined to primary prevention of cardiovascular events, and can be considered as “individualized coronary risk scoring” for those not considered to be of high or low risk. Medical practitioners should carefully counsel patients prior to CAC. CAC should only be undertaken if an alteration in therapy including embarking on pharmacotherapy is being considered based on the test result. Patient groups to consider Coronary Calcium Scoring 1. CAC is of most value in intermediate risk patients (absolute 10-year cardiovascular risk of 10-20%) who are asymptomatic, do not have known coronary artery disease and aged 45 – 75 years, where it has the ability to reclassify patients into lower or higher risk groups. 2. It may also be considered for lower risk patients (absolute 10-year cardiovascular risk 6-10%) particularly in those where traditionally risk scores under estimate risk e.g.
