  • single center

Authors' conclusion

Patients without prior ASCVD but with severe CAC (score ≥7) on CTAC demonstrated a risk for cardiovascular events and mortality comparable to those with known ASCVD, highlighting the need for more aggressive management in this high-risk primary prevention group.
