Without delay, let’s delve into the relevance and importance of the heart calcium score scan in assessing heart disease risk.

Why Does the Heart Calcium Score Matter? 

The Heart Calcium Score, also known as the Coronary Artery Calcium (CAC) Score, is an essential tool in modern heart health. It helps evaluate the presence and extent of calcified plaque in the coronary arteries, offering critical insights into a person’s risk of cardiovascular diseases. This discussion will cover the significance of the coronary calcium score, its measurement process, and its role in assessing cardiovascular risk.

Other Terms Used for the “Heart Calcium Score”:

  • Coronary Artery Calcium (CAC) Score
  • Coronary Calcium Score
  • Coronary Calcium CT Scan
  • Heart CT Calcium Scan
  • Heart Calcium Scan
  • Cardiac Calcium Scoring
  • Calcium Scan of the Heart
  • Cardiac Scoring
  • Coronary Calcium Test

Coronary Calcium Score: An Overview 

A Coronary Calcium Imaging measures the calcified plaque within the coronary arteries using a CT scan. This score serves as a marker for advanced atherosclerosis, characterized by the buildup of calcium deposits in the arteries. Plaque formation, consisting of fats, cholesterol, and other substances, and its accumulation in the coronary arteries, is a key process in the development of heart disease.

Atherosclerosis often starts in the early 20s and progresses over time. In its early stages, plaque is soft, but as the condition advances, chronic inflammation and fibrosis occur, leading to calcification. The amount of calcified plaque strongly indicates the severity and duration of atherosclerosis. 

However, it is important to understand that a high cardiac calcium score does not always translate to imminent cardiovascular disease. It signifies the extent of calcium buildup in the coronary arteries but not the instability of the plaque, which is a key factor in predicting heart attacks or strokes, or the capability of the coronary arteries to provide proper blood flow to the heart.

Measuring Coronary Calcium 

Obtaining a coronary calcium scan is straightforward and non-invasive. A CT scan without IV contrast or dye is used to visualize the calcified plaques in the coronary arteries. The score is standardized based on gender, ethnicity, and age, providing a tailored assessment for each individual.

The clinical significance of the coronary calcium score lies in its ability to provide an independent risk assessment for cardiovascular disease. This score adds valuable information beyond traditional risk factors such as obesity, diabetes, hypertension, systemic inflammation, or dyslipidemia. While these factors are critical, the CAC score offers additional insights into the long-term impact of atherosclerosis.

Interpretation of the Calcium Score 

The Heart Calcium Scan is interpreted on a scoring scale, with varying implications based on the score. Yet, it is fundamental to realize that the calcium score alone does not fully reflect heart health.

  • Zero Score: Often referred to as “the power of zero,” a calcium score of zero is excellent news. It indicates no significant calcified plaque, suggesting a low risk of prolonged and severe atherosclerosis and, consequently, a low risk of cardiovascular events like heart attacks or strokes. However, it is important to note that this does not rule out the presence of soft, non-calcified plaques, which are in the earlier stages of atherosclerosis.
  • High Score: A high calcium score indicates a higher risk of cardiovascular events. Individuals with high scores require further investigation, often through nuclear or treadmill cardiovascular stress testing. Additionally, traditional risk factors such as LDL cholesterol and hypertension need to be tightly controlled to reduce the risk of future heart problems.
  • Intermediate Score: An intermediate calcium score, around the 50th percentile, presents a more ambiguous risk. It neither confirms nor rules out a high risk of cardiovascular events, making clinical decision-making more challenging. Further evaluation and monitoring are usually necessary for individuals with intermediate scores.
Dr. Tashko, lipidologist, explains how to interpret heart calcium score values, guiding patients on understanding their cardiovascular risk and necessary actions.

The Role of Cardiac Scoring in Cardiovascular Risk Assessment 

The Coronary Calcium Score is a valuable tool in assessing cardiovascular risk because it provides additional information that traditional risk factors might not reveal. For instance, two individuals with similar LDL cholesterol levels and blood pressure might have different CAC scores, indicating different levels of underlying atherosclerosis. This additional layer of information helps endocrinologists tailor preventive and therapeutic strategies more effectively.

Moreover, the Coronary Calcium CT scan is particularly useful in identifying asymptomatic individuals who might otherwise be unaware of their cardiovascular risk. Early detection of calcified plaque allows for timely interventions, which can significantly reduce the risk of future cardiovascular events. Lifestyle changes, medical therapy, and regular monitoring can be initiated based on the coronary calcium test, leading to better outcomes.

Who Should be Tested with a Heart CT Calcium Scan? 

Anyone interested in understanding their cardiovascular risk should consider a Heart CT Calcium Scan. It is particularly useful for individuals with predispositions to heart attack or stroke, such as high LDL cholesterol, apoprotein B, Lipoprotein(a), small dense LDL particles, hypertension, diabetes, smoking, insulin resistance, metabolic syndrome, chronic kidney disease, and fatty liver disease

This test is also recommended for those with a family history of early heart disease, especially if parents or siblings experienced heart attack, stroke, or peripheral vascular disease before age 60. The scan provides valuable insights, helping to tailor prevention and treatment strategies successfully.


The Heart Calcium Score is an essential tool in modern cardiovascular risk assessment. It provides a clear picture of the extent of calcified plaque in the coronary arteries, offering valuable insights beyond traditional risk factors. By measuring the end-stage process of atherosclerosis, the coronary calcium score helps identify individuals at higher risk of cardiovascular events.

The power of the Heart Calcium Scan lies in its ability to provide independent risk assessment, complementing other indicators such as LDL cholesterol, blood pressure, and diabetes. This score is particularly beneficial for early detection and intervention, which are crucial in preventing heart attacks and strokes.

Incorporating the CAC Score into routine cardiovascular risk assessment can lead to more personalized and effective prevention strategies, ultimately reducing the weight of the cardiovascular disease. Whether the score is zero, high, or intermediate, understanding its implications and acting accordingly can make a significant difference in managing someone’s cardiovascular health.
