What Is MDCT Coronary Artery Calcium Scoring?
Coronary Artery Calcium Scoring (CACS) is a non-invasive way of obtaining information
about the location and extent of calcified plaque in the coronary arteries -
the vessels that supply oxygen-containing blood to the heart wall. The findings
on cardiac MDCT, expressed as a calcium score, help to decide what measures should
be taken to avoid increased plaque buildup and more advanced disease.
What Is Coronary Artery
Plaque?
Plaque is a build-up of cholesterol and other substances, including calcium,
which over time can narrow and may eventually close off the arteries which supply
blood to the myocardium (heart muscle).
Who Should Get a CACS?
It is a diagnostic study that may be ordered by your physician if you have risk
factors for CAD but no clinical symptoms yet. The procedure is most often suggested
for men aged 45 years or older and for women aged 55 and above or are postmenopausal.
