Coronary Calcium Scan Age: Who Should Get One at 40+?

Heart disease may also be silent and progressive over many years in patients who may be otherwise healthy and active individuals.

As one gets past the age of 40, the question often arises whether more tests are necessary to screen for potential heart problems apart from regular monitoring of blood pressure and cholesterol.

A coronary calcium scan may be one way of addressing this concern in certain patients by looking for calcification in coronary arteries responsible for supplying blood to the heart.

But age isn’t the only factor in deciding about the appropriateness of this test. Your cholesterol numbers and cardiac risk profile are important too.

What Are Coronary Calcium Scans?

A coronary artery calcium scan is a specific CT scan designed to identify the presence of calcium in coronary arteries. Calcium is present in the calcified plaque and serves as one of the indicators of atherosclerosis, a process in which plaque starts building up in arteries.

This kind of scan gives the patient his or her calcium score, showing the level of the calcified plaque present in coronary arteries. Score 0 means that there is no presence of coronary artery calcium, while higher scores mean more calcified plaque.

But having a score of 0 does not necessarily mean that there is no coronary artery disease at all since the plaque may be noncalcified. This test does not give information about blood flow and blockage of an artery.

Coronary Calcium Scan Age: Is 40 Too Early?

There is no single age at which everyone should get this scan. When adults are in their 40s to 75 years of age, and their cardiovascular risk is unclear, and the test result will have an impact on preventive treatment, it can become a more important issue to consider.

The correct coronary calcium scan age varies according to personal circumstances:

1. In your 30s: Screening is not usually required in low-risk patients. Some selected young individuals with a strong family history and other risk factors will need personalized evaluation.
2. In your 40s: The test may help some adults with borderline or intermediate cardiovascular risk determine whether cholesterol-lowering drugs are required or not.
3. In your 50s to 60s: It may help to make a decision about treatment when traditional risk factors cannot give a definite answer.
4. After 75: The benefits are not clear in routine screenings; the decisions should be made individually.

The above-mentioned ages are general guidelines, not automatic tests.

When to Get a Coronary Calcium Scan

When should one get his/her coronary calcium score? This test is recommended when the results would impact the management decision.

This test is recommended in adults who are asymptomatic but have a dubious risk profile for heart disease based on the calculated cardiovascular risk.

For example, a person aged 48 years with high cholesterol and early onset of heart disease in his/her family can undergo a CAC score test to know his/her risk profile. The test would then tell the physician to put the patient on a statin medication.

In contrast, a patient with known coronary artery disease would not require a coronary calcium score test to establish the existence of plaque. In case of any chest pains or indications of heart attacks, the patient should visit the physician immediately.

Understanding Coronary Calcium Screening by Age

The use of coronary calcium scanning depends on age and should depend on a person’s total risk level, not age alone.

Healthcare professionals can take into consideration other risk factors, including a person’s cholesterol levels, high blood pressure, diabetes, smoking, and genetics, among others, before recommending such tests.

It is a fast test that is painless and noninvasive; it does not require needles. Nonetheless, it involves the use of ionizing radiation and may have some unexpected results leading to more tests being done. It is not advisable for all adults. Calcium score should be taken together with other risks.

Conclusion

Coronary calcium scans may be helpful for cardiovascular risk evaluation among certain adults, especially those above 40 years whose necessity for preventative care is uncertain.

Not everybody requires it, and there is a specific time when it should be done depending on individual risks and medical conditions. If you plan to have such a test, talk to your physician and evaluate your cardiovascular risk.
