Heart disease remains one of the leading causes of death worldwide, often progressing silently until serious symptoms emerge. Detecting risks early is crucial, and one tool gaining attention is the coronary calcium score test. This scan provides a window into the health of your heart’s arteries long before symptoms develop, offering potentially life-saving insights. Understanding what a calcium score means, how it varies by age, and what steps to take if yours is high can empower you to manage your heart health proactively.
What Is the Calcium Score Test? A Clear Picture of Your Heart’s Health
A coronary calcium scan measures the amount of calcium deposited in the coronary arteries—the very vessels that supply blood to your heart muscle. According to Dr. Christopher Berg, a board-certified cardiologist at MemorialCare Heart and Vascular Institute, this test effectively quantifies plaque build-up, which includes calcium, within these arteries. The presence of calcium is significant because it often indicates coronary artery disease (CAD), a primary cause of heart attacks.
Unlike more invasive procedures, the calcium score test uses a low-dose computed tomography (CT) scan to capture images of the heart. It is painless, takes only a few minutes, and exposes patients to minimal radiation. The results come in the form of a score, known as the Agatston score, reflecting the extent of coronary calcium. A higher score suggests more plaque and a heightened risk for heart disease.
How Age Influences Your Calcium Score: What to Expect at Different Stages of Life
Calcium accumulation in arteries typically increases with age. Younger individuals generally have low or zero calcium scores, reflecting healthier arteries. However, it is not rare for middle-aged or older adults to have some degree of calcification, even if they feel well.
-
Adults under 40 usually have a calcium score close to zero unless risk factors like a strong family history or smoking are present.
-
Between ages 40 and 60, small increases in calcium deposits are common, though a high score is more concerning.
-
For those over 60, moderate calcium scores may reflect normal aging, but very high scores require medical attention.
While age-related increases are expected, what matters most is how your score compares with others in your age group. A calcium score significantly higher than average for your age could indicate accelerated plaque build-up, signaling elevated risk even if you have no symptoms.
What Happens If Your Calcium Score Is High for Your Age? Taking the Next Steps
When a high calcium score emerges, it serves as an early warning of coronary artery disease. This score alone does not diagnose blockage severity but highlights the need for further evaluation. Doctors may recommend lifestyle changes and preventive treatments depending on your total risk profile, which considers cholesterol, blood pressure, diabetes status, and family history.
Typical recommendations include:
-
Adopting a heart-healthy diet rich in fruits, vegetables, and whole grains.
-
Initiating or increasing physical activity.
-
Using medications like statins to lower cholesterol and stabilize plaques.
-
Quitting smoking if applicable.
-
Ongoing monitoring through follow-up tests or imaging.
Addressing a high calcium score proactively can reduce the risk of heart attack, stroke, or other complications.
How Often Should You Get Screened? Timing Your Calcium Score Test Appropriately
Screening guidelines vary, but the calcium score test is usually considered for patients with intermediate risk of heart disease, often between ages 40 and 75. It is especially helpful when uncertainty exists after traditional risk assessments.
-
If you have multiple risk factors but no symptoms, a one-time scan can clarify your risk.
-
Repeat screening might be advised every 3 to 5 years if your initial score is above zero.
-
For low-risk individuals, routine screening is generally not recommended.
Discuss with your healthcare provider if a coronary calcium scan suits your individual risk profile.
Calcium Tests May Be Covered by Insurance: What You Should Know
Insurance policies often vary regarding coverage of coronary calcium scans. Many providers recognize the test as medically necessary for risk assessment in patients with some risk factors, improving chances of coverage.
-
Check with your insurer to confirm if the test is included under your plan.
-
Some diagnostic tests require a referral from a cardiologist or primary care physician.
-
Out-of-pocket costs can vary but are generally affordable compared to invasive heart tests.
Insurance coverage helps make this valuable screening accessible to a wider population, encouraging early diagnosis and prevention.
Taking control of your heart health starts with understanding tools like the coronary calcium score test. By identifying calcifications early, this scan enables informed decisions and prompt measures to reduce the risk of heart disease. Monitoring your calcium score along with other risk factors gives you the best chance to maintain a healthy heart throughout life. If you wonder whether a calcium score test is right for you, consulting a healthcare professional can help tailor screening and prevention strategies to your needs.
