Insurance companies often don't cover coronary calcium scans because they are considered a preventive measure, not a diagnostic one.
This means that insurance companies may view the scan as a way to detect potential problems before they become serious, rather than a necessary treatment for an existing condition.
As a result, many people are left to pay out-of-pocket for the scan, which can cost anywhere from $100 to $500.
The importance of early detection cannot be overstated, as undiagnosed coronary artery disease is a leading cause of heart attacks and strokes.
What is a Coronary Scan?
A coronary scan is a type of X-ray called a CT scan that takes pictures of your arteries to check for calcium.
This scan uses a special type of X-ray technology to visualize your heart's blood vessels, specifically looking for calcium buildup in the arteries.
The scan is called a coronary calcium scan, or calcium scan test, and is also known as cardiac CT for calcium scoring.
A coronary calcium scan is a non-invasive test that can help your doctor get a clearer picture of your risk of having a heart attack.

What Is a Coronary Scan?
A coronary scan, also known as a coronary calcium scan, is a non-invasive test that uses a special type of X-ray called a CT scan to take pictures of your arteries.
It's a quick and painless procedure that can help your doctor get a clearer picture of your risk of having a heart attack. Your doctor can use this scan to check for calcium buildup in your arteries, which can be a sign of heart disease.
The scan is called a coronary calcium scan because it specifically looks for calcium deposits in the coronary arteries, which are the vessels that carry blood away from your heart.
The scan is often referred to by other names, including a calcium scan test and a cardiac CT for calcium scoring.
Here are some alternative names for the coronary calcium scan:
- Coronary calcium scan
- Calcium scan test
- Cardiac CT for calcium scoring
How Does a Coronary Scan Work?
A coronary scan uses a CT machine, which is a special kind of X-ray equipment that uses a small amount of radiation.
The machine will scan your heart to take detailed images. Any calcium specks on the walls of your heart arteries will show up on the images.
You don't have to take any sort of dye for this test, which is a relief if you're worried about added discomfort.
A technician will do the test, and then your doctor will look at the results. You'll get a score based on how much calcium is found.
The machines used can vary, but they all quickly take multiple images that a computer can combine into detailed 3D pictures.
Benefits and Importance
A coronary calcium scan can give your doctor more information about your risk for heart disease, especially if you already have risk factors. This can help you make decisions about how to lower your risk.
You can make lifestyle changes such as having a heart-healthy eating plan, staying at a healthy weight, getting more exercise, and quitting smoking. This can be a great way to take control of your heart health.
A coronary calcium scan takes about 30 minutes and is a non-invasive test that uses a CT scanner. The test is quick and easy, and it can provide valuable information about your risk for heart disease.
Calcium plays important roles in the heart's electrical and pumping activities, allowing it to keep a steady rhythm and keep your blood moving. This is a crucial function of calcium in the heart.
However, calcium also plays a role in atherosclerosis, a condition in which fat and cholesterol deposits called plaque build up inside your arteries. This can increase your risk of a heart attack.
Most people over age 70 and almost everyone with coronary artery disease will have at least some of these calcium deposits. This is a common occurrence as people age.
A coronary calcium scan can help identify these deposits and provide your doctor with more information about your risk for heart disease. This can help you make informed decisions about your health.
Here are some key benefits of a coronary calcium scan:
- It can help identify early heart disease before it gets worse.
- It can give your doctor more information about your risk for heart disease.
- It can help you make decisions about how to lower your risk for heart disease.
- It's a non-invasive test that takes about 30 minutes.
Who Should Get Tested?
If you're wondering who should get tested for coronary calcium, the answer is anyone with a family history of heart disease. People with a family history of heart disease are more likely to have a high coronary calcium score.
Those with a history of smoking are also a good candidate for testing, as smoking is a significant risk factor for heart disease. Smoking can damage the inner lining of blood vessels, leading to plaque buildup.
Men over 45 and women over 55 with risk factors such as high blood pressure, high cholesterol, or diabetes should also consider getting tested. These individuals are more likely to have undiagnosed heart disease.
Even if you're feeling fine, if you have a history of high blood pressure, high cholesterol, or diabetes, you should talk to your doctor about getting tested. Early detection is key to preventing heart disease.
Risks and Considerations
A calcium score test is a relatively safe procedure, but like any medical test, it's not without risks. The good news is that it doesn't involve an injection of contrast dye, so you won't experience any side effects from that.
There's a very small risk of cancer associated with having a calcium score test, particularly if you're younger than 40 and have had multiple CT scans. This is because the test exposes you to a small amount of radiation, roughly equivalent to what you'd naturally receive in a year.
Risks of a Score Test
A calcium score test is generally a safe procedure, but like any medical test, it does come with some risks.
There's a very small risk of cancer, especially if you're younger than 40 and have had multiple CT scans. This is because a calcium score test exposes you to a small amount of radiation, equivalent to what you'd naturally get in a year.
If you're pregnant, it's best to avoid a calcium score test altogether, as a CT scan could potentially harm your unborn baby.
Some people may not find a calcium score test particularly helpful. These include individuals who don't have any risk factors for heart disease, as well as those who have already been diagnosed with coronary artery disease or are experiencing symptoms that suggest it.
New Guidelines Based on CAC Testing
New guidelines have been developed based on Coronary Artery Calcium (CAC) testing. These guidelines aim to identify vulnerable patients who are at high risk of heart attacks and strokes.
The SHAPE (Society for Heart Attack Prevention and Eradication) organization created a new set of guidelines that utilize noninvasive imaging of atherosclerosis, specifically CAC testing. This focus on identifying vulnerable patients began almost two decades ago.
Research has shown that asymptomatic individuals with high levels of CAC scores are at the highest risk of ASCVD (Atherosclerotic Cardiovascular Disease) events. In fact, studies indicate that these individuals have a 25% higher risk of heart attacks and strokes.
The SHAPE Guidelines categorize patients into different risk levels based on their CAC scores. The "Intermediate Risk" category is a key focus of these guidelines, as it accounts for the majority of ASCVD events.
Cost-effectiveness analysis has shown that adopting the SHAPE Guidelines could save the US healthcare system $21.5 billion annually. This is because CAC testing is a cost-effective method of identifying high-risk patients, compared to other diagnostic tests like stress electrocardiography and nuclear stress tests.
Here's a breakdown of the estimated impact of adopting the SHAPE Guidelines:
These guidelines have the potential to make a significant impact on public health and reduce the burden of ASCVD events.
Coronary Artery Scans Not the Answer
Coronary artery scans may not be the answer for everyone. They can be expensive and may not provide a clear diagnosis.
A CT scan can cost upwards of $1,000, which can be a significant financial burden for many people. In some cases, the results may be inconclusive or misleading.
Many people who undergo coronary artery scans may not even need them. According to the article, 75% of people who undergo a CT scan do not have any coronary artery disease.
In fact, one study found that 90% of people who undergo a CT scan do not have any significant blockages in their coronary arteries. This can lead to unnecessary stress and anxiety for those who receive a false positive result.
When to Get Tested?
You're likely wondering when to get a coronary calcium scan. The test isn't for everyone, so it's essential to know when it makes sense.
To determine if you're a good candidate for the test, your doctor will consider your age, blood pressure, cholesterol level, smoking status, and gender.
Your age plays a significant role, typically ranging from 40 to 70 years old. This is because you're more likely to have a moderate chance of heart disease during this period.
The test isn't recommended if you have a low chance of coronary artery disease, as it's unlikely to show any calcium buildup. On the other hand, if you have a high chance, you won't learn anything new that can help you.
Here's a quick rundown of who might benefit from the test:
- Age: 40-70 years old
- Some heart risks, but no symptoms
Insurance usually doesn't cover this type of scan, so it's a good idea to check on that before getting the test. The cost is typically around $100 to $400.
Why Have a Score Test?
A coronary calcium scan is a test that can give you valuable information about your heart health. The scan is done to see if you have any calcium deposits in your arteries and, if so, how many.
High amounts of calcium mean you have high amounts of plaque, which is like a clog in a pipe that slows down your blood flow. This can lead to chest pain and discomfort, called angina, and even a heart attack.
The scan can help you and your doctor decide if you need to make any changes to your medicine or lifestyle. But to get the most out of the test, you need to know how likely you are to get heart disease.
Your doctor can figure this out based on factors like your age, blood pressure, cholesterol level, whether you smoke, and your gender. Typically, the test makes the most sense if you have a moderate, or medium, chance of heart disease based on these things.
If you have a medium chance, you may be able to take steps to avoid heart disease based on the scan results. For example, the test might help people who are struggling to decide whether to take a statin to lower their cholesterol or resume statins after having some side effects.
Here are the factors your doctor will consider to determine if you're a good candidate for the test:
- Your age
- Your blood pressure
- Your cholesterol level
- Whether you smoke
- Your gender
Keep in mind that insurance usually doesn't cover this kind of scan, so it's a good idea to check on that before you get the test. The cost is usually around $100 to $400.
