In this video, we’re going to talk about how to read your coronary artery calcium (CAC) score.

A CAC test will tell you the amount of calcium plaquing that is in your arteries.

When the inside of blood vessels becomes injured or inflamed, your body repairs the damage with calcium and cholesterol.

Your risk of heart attack is increased if you have high calcium in your arteries.

90% of men and 67% of women over the age of 70 have some amount of calcium in their arteries.

Consuming a high amount of carbohydrates is the primary cause of artery damage—it causes a large amount of irritation and inflammation.

Your CAC score can go from 0 to over 1000. Ideally, you want your score to be 0.

The CAC test is one of the best predictors of mortality from all causes.

Here’s how you can read your CAC score:

Score: 0

• Plaque: none

• Probability of heart disease: very low

Score: 1-10

• Plaque: minimal

• Probability of heart disease: low

Score: 11-100

• Plaque: mild atherosclerosis

• Probability of heart disease: minimal

Score: 101-400

• Plaque: moderate atherosclerosis

• Probability of heart disease: moderate

Score: 400+

• Plaque: extensive atherosclerosis

• Probability of heart disease: high
