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 70%, that means you have more calcium in your heart arteries than 70% of men or women your age. Only 30% have more calcium than you have. It means your arteries are aging faster than you are.

percentile score 70-79%

In this study, a 70-79 percentile score was associated with a 36% ten year risk (2).

Less than 7.5% is considered normal risk. High risk is 20% or more. In this high risk group, you have a 1 in 3 chance of a major heart event in the next 10 years. By a major heart event, we mean a heart attack or sudden death. High intensity statins and high intensity risk management is recommended.

Write down that number and circle it: 36%.

  1. Because most events occur in the highest percentile groups, the percentile score is a more effective way to predict risk than the calcium score alone. Incorporating the percentile score, the MESA trial showed that the heart calcium score “was better than all the other risk factors combined for risk prediction.” Sharma, et al, Cardiac risk stratification: Role of the coronary calcium score.
