A normal calcium score is zero. This indicates that no calcification was detected in the arteries of the heart during the test.
Understanding a Calcium Score of Zero
According to the Cleveland Clinic, a calcium score of zero, often called a negative scan, means that there is no visible buildup of plaque in the arteries of your heart. This result is very favorable and suggests a very low risk of heart attack in the immediate future.
- No Calcification: The absence of calcium buildup means there is no hardened plaque present in the arteries, which could lead to reduced blood flow to the heart.
- Low Risk: A score of zero is associated with a very low chance of experiencing a heart attack in the next two to five years.
- Reassurance: This result provides reassurance regarding the health of your coronary arteries.
Why is a Calcium Score Important?
A calcium score helps to detect early signs of coronary artery disease (CAD) before symptoms occur. CAD is often caused by a build up of plaque in the arteries that can narrow or block blood flow to the heart, leading to a heart attack. The calcium score is a helpful tool for understanding your risk level and starting preventive measures if needed.
What the Different Scores Mean
| Calcium Score | Risk Interpretation |
|---|---|
| 0 | Normal. Indicates no visible plaque and very low risk. |
| 1-100 | Mild plaque buildup. Low to moderate risk of heart disease. |
| 101-400 | Moderate plaque. Moderate risk of heart attack. |
| Over 400 | High levels of plaque. High risk of heart attack. |
What To Do With a Normal Score
Although a calcium score of zero is a very good result, it does not mean that all cardiovascular risks are eliminated. It's still important to:
- Maintain a healthy lifestyle that includes a balanced diet, regular exercise, and avoiding smoking.
- Discuss your overall heart health with your doctor, particularly if you have other risk factors for heart disease, such as high blood pressure, high cholesterol, or a family history of heart disease.
In summary, a calcium score of zero is considered normal and indicates a very low risk of a heart attack in the next two to five years based on the absence of calcified plaque in your heart’s arteries.
