Welcome to Mayo Connect @pkoutou, you have come to the right place to learn more about high calcium scores. While waiting for others to chime in and respond to your question, I'd like to say that this site is a members site and not so much about medical advice, but we certainly can offer our opinions or share our stories.
Have you done a search on "high calcium scores" in the search area? There are several discussions you may find informative, from members with your same situation.
Obviously, only your doctor can guide you in your next steps, but you also may need to be your own advocate and push for additional testing.
Learn as much as you can, both here on Mayo Clinic and elsewhere. Be informed about choices available and ask your doctor to refer you to a cardiologist as necessary. High calcium scores can be very scary, and they certainly need to be addressed by your physician. Do you have a cardiologist already? Is this something that just came out of the blue, or have you had symptoms?

Out of the blue. No symptoms whatsoever and just had a nuclear stress test and all results were normal.

What is your age? Physical condition including weight?

Diagnosed with heart disease? High blood pressure?

What are your basic lipid numbers?

Have you had Cardio IQ (advanced lipids panel)?

What were the numbers from the stress test? METS, Duke, etc?

What were Ejection Fractions (EF)?

Are you taking a statin - which one and what dosage? When did you start taking the statin?

Sorry - but this is a bit of a game of numbers to begin with 🙂

Have you discussed the results with your primary care provider? Seems like this person would be the place to start. Then perhaps get a referral to a cardiologist? I got a high score also and am winding my way through it too. Waiting to see a cardiologist.

On this forum, I saw a recommendation for the book "Beat the Heart Attack Gene" by Bale et al. I found it to be the best main stream reference I've run across so far. It will give you some background and a starting place for mapping out a plan along with your care provider.

Good luck. I would be interested to hear back on the plan you come up with along with your care provider or cardiologist.
