You're not going to die within the next hour. Doctor will likely recommend an angiogram to see what the story is. You can just ask for one, in fact.

If you are feeling fine, no need to panic. If you had the diagnosis because of angina/chest pain, then it might mean you are going to need imaging and possibly an angioplasty or a bypass operation. No sense in brooding about it just yet...too early to lose sleep. Again, if you feel fine, enjoy life. In time, as bitsgirl suggests, you will be asked to submit to a number of procedures. For me, with an arrythmia, it was the nuclear stress test first, with chest x-rays, eventually an MRI of my chest, and finally a catheter angiography where they slide a thin tube the size of a toothpick up my wrist to my heart and had a look with a tiny camera (fiber optic). I was awake, although the gentleman surgeon asked if i though I might want a gentle sedative. I declined, and soon felt the thin wire zip up my arm, into my armpit, and after that there are thankfully no nerves. Six minutes later, I feel him pull it out, he leans over and said, 'Only minor deposits, you're good.' The worst part of it all? Having to lie still back in my cubicle for about three hours until they were sure I wouldn't bleed from the incision. I kept waving my hands around, when I talked so they put my arm in sling which stopped that right short. The talking...not my arm waving. 😀

Thank you guys! You all seem smart, kind, and supportive, one of my favorite combinations. I have poked around this site and several others. I prefer to get information from multiple sources, and you folks are right in line with the prevailing opinions I have encountered which includes that of my PCP. As far as lifestyle changes, I can't even begin to list what I've altered or eliminated in order to still be above ground in 2025. All worth it . . . so far. 🙂

Walk (don't run) to your cardiologist! Seriously, I'm in your boat, I'm going to see a cardiologist on monday and then get a second opinion if he recommends anything invasive.

Reply to orionex, i had 3500 2 years ago, passed stress test and now take statin and baby aspirin. I haven't done angiogram although cardiologist suggests it. He said ct angiogram would be inconclusive because of so much calcium.
I am getting second opinion from a different healthcare practice.
Incidentally, my cardiologist said he had a 55 year old athletic guy with over 5000 and his angiogram showed no blockage, bucking the test's odds.
I am alert in case i get symtoms.
If second opinion suggests angiogram, i very well might do it.

Hmm, CT A (Angiogram) uses contrast dye to see how much of each artery is blocked. The calcium can be all over the place, so it might be easy to see each artery (you have the four coronary readings from the CAC right?).My calcium is in the LAD and the RCA (with only a bit in the other two) - but my total is 'only' 1,000. Still it seems that the CTA would be better than sticking a catheter with a balloon up your crotch as the first order of business!

Hello @orionrex,

I moved your discussion and combined it with @heycal's discussion:

"Crazy high calcium score of 4,000+"
- https://connect.mayoclinic.org/discussion/crazy-high-calcium-score/

@heycal may have some experiences they would like to come back and share based on getting shocking calcium scores as well. @cianci also shared their experience with a score of 3,500.

@orionrex - it sounds like you were able to discuss your score with your PCP and make some lifestyle changes that have helped ease some of the short-term concerns. If you don't mind sharing, what sort of changes have you already made?
