You’ve had a stent

stents increase the calcium score. Having a bypass surgery also increases calcium.

One way to interpret your calcium score is to ask the CT technician to look at your “Site-Specific Report” and to subtract the calcium in the segment with the stent from the total calcium score. Your new total gives you a better understanding of how much calcium is in the non-stented coronary arteries.

Another way to look at your risk is this: because you’ve had a stent or a bypass, you know already that you have high risk for having an event. So you don’t need to try to calculate your risk. Your risk is high.
