CAC 149, almost all in the LAD: what would you do next?

A 49-year-old with good lipids and a concentrated calcium score prompted a clear consensus on the next test.

The case: a 49-year-old man with ApoB treated to 75, Lp(a) under 10 and clean inflammatory markers, but a CAC of 149 with 97% in the LAD.

The group's answer was coronary CTA next, citing SCAPIS (n = 24,791) and SCOT-HEART, where low-attenuation plaque burden above 4% was linked to a fivefold increase in heart attack.

Members then compared plaque analysis platforms: Cleerly for plaque morphology, HeartFlow for virtual FFR, and Caristo for perivascular inflammation, not yet FDA-approved in the US. Photon-counting CT is coming but is currently limited to a few centers such as Mayo, MGH and NIH.

Key takeaways

  • A concentrated LAD calcium score warrants CCTA even with good lipids.
  • Choose the plaque analysis platform for the question you are asking.
