A calcium score scan, also known as a coronary artery calcium (CAC) scan, is a specialized X-ray test that measures the amount of calcium in the walls of the coronary arteries. These arteries supply blood to the heart muscle, and calcium buildup in them is a marker of atherosclerosis, or the hardening of the arteries, which can lead to heart disease.

Importance of a Calcium Score Scan

Assessment of Heart Disease Risk: The primary Goal of a calcium score scan is to assess an individual's risk of developing coronary artery disease (CAD). The amount of calcium detected correlates with the likelihood of significant atherosclerosis and the risk of a future heart attack.

Early Detection: The scan can detect the presence of coronary artery calcification before symptoms of heart disease appear, allowing for earlier intervention and management.

Guiding Treatment Decisions: The results of a calcium score scan can help us decide on the best course of action. a higher calcium score might lead to more aggressive lifestyle changes, medication (like statins), or other interventions to reduce cardiovascular risk.

Personalized Risk Assessment: The calcium score provides a personalized assessment of heart disease risk, beyond traditional risk factors like age, cholesterol levels, blood pressure, and family history.

Monitoring Disease Progression: In some cases, repeated calcium score scans can be used to monitor the progression of coronary artery disease over time.
