When it comes to avoiding cardiovascular disease, I always urge patients to test, not guess. This includes getting a CAC scan, especially if you’re at or above the age of 40.
It may not be convenient to schedule a CAC. It’s probably a little nerve wracking, too.
But testing today could potentially save your life tomorrow.
It could be the difference between a heart attack and a healthy life.
I realize many people aren’t familiar with CACs, or have a few questions before scheduling a test. I want to demystify some common questions below so you can feel more confident about booking a scan.
Let’s get started.
What is a CAC scan?
A coronary calcium scan (or CAC) is a type of imaging test for your heart. It’s designed to spot calcium deposits in your arteries, which can increase your risks for heart disease.
Although CAC scans are relatively new, their accuracy is hard to ignore. Research shows it predicts cardiovascular disease with high accuracy, even for asymptomatic individuals.
In my opinion, it’s one of the best tests to identify the early stages of heart disease.
When should I get a CAC scan?
I tell patients to schedule their first CAC at 40, especially if they’re male. Since men tend to develop heart disease earlier than women, the sooner you test, the better.
That said, may want to get a CAC scan earlier than 40 if:
- You have a family history of heart disease
- You have existing risk factors like hypertension or diabetes
- You smoke or have smoked in the past
How often should I get a CAC scan?
Most patients should schedule CAC scans every three to five years. This makes it easier to track lifestyle changes in your diet, exercise patterns, and stress management behaviors.
But if you’ve already been diagnosed with heart disease, a CAC scan won’t make much sense. Your score won’t tell you anything you don’t already know. Remember: these tests are for diagnosis, not existing medical presentations.
Where do I get a CAC scan?
CAC scans require physician referral, so you can talk to your doctor about ordering a test. From here, you should report to the recommended clinic to have the procedure completed.
That said, it may be difficult to get your doctor onboard. Many patients came to me after their doctor refused to order a CAC.
If this happens to you, I urge you to find a new doctor. That individual cannot help you become or remain healthy — they can only help you manage future illnesses.
What is a CAC scan like?
A CAC scan is a lot like an x-ray. It only takes around 10 to 30 minutes to complete, and you don’t have to fast like you would with blood work.
Let’s walk through an example appointment so you know what to expect:
- You lie down on an imaging table while technicians attach electrodes to your chest. This is to monitor your heart’s electrical activity and develop a more accurate image.
- The imaging table pulls you into the scanner and begins collecting data. This usually takes about 10 to 15 minutes.
- There is a two-way speaker attached to the imaging station. Your technician may ask you to hold your breath occasionally. This is normal.
You can walk and drive normally once the procedure is complete. Expect to receive your CAC score within two to three days of your visit.
How do I interpret my CAC score?
Coronary calcium score guidelines are relatively straightforward: the lower your score, the lower your risk. The higher your score, the higher your risk.
An Agatston score of zero means you have a very slim chance of developing heart disease. Higher numbers between 100 and 300 indicate a moderate risk. Scores of 1,000 or more should be a major wake-up call.
If your CAC score isn’t close to zero, you need to take immediate action to restore your metabolic health.
How much does a CAC scan cost?
This depends on your location and imaging center. Some tests are as low as $60, while others go up to $400. Be prepared to pay at least $250 so you’re not blindsided by the price.
Unfortunately, most insurance companies don’t cover the cost of a CAC scan. You likely have to pay the full cost for the procedure unless you have a great insurance company (or want to use your HSA).
You may also have to wait a long time for your appointment, especially if you live in a rural area. If you’re lucky enough to live in a metro, you may be able to schedule same-day appointments.
What do I do if my CAC scan isn’t zero?
A CAC score above zero doesn’t mean you’re in immediate danger. But the sooner you make progress on your metabolic health, the less concerned you need to be about heart disease.
If you’re worried about your recent CAC score, don’t panic. I’ve seen many scores improve with a focus on metabolic health.
I recommend:
- Eating only whole, real foods, which are things that come from the ground or are nourished by the ground.
- Carving out 30 minutes per day for physical exercise, whether that’s taking the stairs at work or lifting weights at the gym.
- Getting enough sleep every night, whatever that means for your body.
- Finding ways to reduce chronic stress, especially if it’s lifestyle or work related.
A CAC is a phenomenal way to get clarity about your health. You manage what you measure, as the saying goes.
That said, I recognize it can be difficult to implement lifestyle changes on your own. It can be even harder with a conventional doctor or if you’re surrounded by people insisting ‘you’re just getting older.’
If you’re looking for a more supportive environment, I recommend plugging into my Elite Health Coaching program. This unlocks access to all my video courses and comes with an assigned metabolic coach to provide support along your journey.
