What is Coronary Calcium Scoring?

Coronary calcium scoring (CAC) is a quantitative method that measures the density and area of calcified plaques in the coronary arteries using a non-contrast, low-dose cardiac CT scan. The result is reported as the Agatston score.

It is used in asymptomatic intermediate-risk individuals to reclassify cardiovascular event risk and to inform treatment decisions (e.g., starting a statin). A score of 0 indicates very low risk and ≥400 indicates high risk.

The acquisition time is short, the radiation dose is low, and IV contrast is not required. However, it does not provide information on plaque stability or non-calcified plaques.

Symptoms

Asymptomatic intermediate-risk individuals
Those with a family history
Decision-making about lipid therapy
Risk assessment in diabetic individuals
Chronic kidney disease
Subclinical atherosclerosis screening

Risk Factors

Pregnancy
Active cardiac symptoms (not contraindicated, but CT angiography is more appropriate)
Very young individuals (no guidelines)
Those already classified as high-risk (unnecessary)
Motion artifact
Arrhythmia

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Performed at the referral of a cardiologist or family physician
  • Results affect lifestyle and medication decisions
  • It does not establish a diagnosis alone; it is combined with clinical assessment
  • Should be followed up with a risk-reduction plan

Treatment Methods

01
Short, low-dose non-contrast CT scan
02
Calculation of the Agatston score
03
Percentile evaluation by age and sex
04
