Can you have a cornary calcium score of 0 and still have blockage? This was on a, CT angiogram 2 years ago...
In brief:
Absolutely; uncommon
at your age. CT resolution is not that good compared with size of heart arteries; the arteries never stop moving, thus can only see large enough accumulations of calcium. At microscopic scale, calcium at base of plaques can been seen in 10 yr olds, but is rarely seen on best CT scans until mid-30s.
Plaque is an accumulation of WBCs, not calcium. CT can't distinguish WBCs or clots in artery lumens.
