Using your percentile score:

Your percentile score is probably the best calcium scan estimate of your 10 year heart risk (1).

Not % blockage

Your percentile score is where you rank compared to a group of people your same age and gender. It is not your % blockage. If your percentile score is 40%, that means you have more calcium in your heart arteries than 40% of men or women your age. And 60% have more calcium than you have.

percentile score 40-49%

In this study, a 40-49 percentile score was associated with a 14% ten year risk (2).

Any 10 year risk less than 7.5% is considered low risk. So your risk is in the intermediate, or moderately high range. Your risk is 2x the normal risk. In your risk group, the American Heart Association recommends taking statin therapy and working to reduce risk by eliminating other risk factors.

Write down that number: 14%.
