What is Coronary Artery Calcium Score?

The coronary artery calcium (CAC) score is a non-invasive test that measures calcific plaque burden in the coronary arteries using non-contrast CT. It is expressed with the Agatston score and independently predicts cardiovascular event risk.

Individuals with CAC=0 are considered low risk and statin therapy can generally be deferred. CAC >100 Agatston units indicates intermediate-to-high risk, and >400 indicates high risk. It clarifies treatment decisions in borderline-risk patients.

Symptoms

The test is for risk assessment in asymptomatic individuals
Ages 40–75 with intermediate risk are ideal candidates
CCTA is preferred in symptomatic patients

Risk Factors

Family history of early CAD
Hypertension
Hyperlipidemia
Diabetes mellitus
Smoking
Metabolic syndrome

When to See a Doctor?

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

  • 10-year ASCVD risk between 7.5–20% (borderline risk)
  • When statin therapy decision needs to be clarified
  • In asymptomatic individuals with family history of early CAD

Treatment Methods

01
CAC=0: low risk, statin generally deferred (5–10 year follow-up)
02
CAC 1–99: lifestyle changes + statin evaluation
03
CAC 100–399: statin therapy and risk factor control
04
CAC >=400: high risk, aggressive statin + aspirin evaluation
05
Lifestyle modification (in all groups)
06
Percentile assessment (comparison by age and sex)

Heart Palpitations

Kardiyoloji

Palpitations are usually due to benign causes, but underlying cardiac rhythm disorders must be ruled out.

Heart Valve Diseases

Kardiyoloji

Valve stenosis or regurgitation increases the workload of the heart and, over time, can lead to heart failure.

Aortic aneurysms are often silent; early diagnosis allows treatment before rupture (a life-threatening tear).
