Is it worth getting a calcium score on a patient who is already on statin therapy?

Plaque, usually TCFA (thin-capped fibroatheroma), benefits immensely from statin Rx. TCFAs are vulnerable plaques that are highly prone to rupture. The pleiotropic effects of statin Rx allow for plaque stabilization and reduce the vulnerability of the plaque to rupture. Calcification of plaque is a ...

Generally, not-someone on statins for a relatively short time (e.g. less than 3 years) who does not want to take medications might be reasonable. Longer-term statin use would typically not be useful unless there are major side effects, in which case, it might make more sense to change to another med...

If the presence of CAC would affect the aggressiveness of statin therapy and target LDL, then may be reasonable to obtain Calcium Scoring CT.

A calcium score can be misleading for both patient and provider in that if it is low, one may believe that there are no vulnerable, plaques or lesions, therefore, if CAD is suspect a calcium score with CT angiogram is the best course of action in my opinion and experience.

No... unless the person was inappropriately prescribed a statin (was/is not statin eligible). An even in that case, you do not need a CAC score to stop the medication.
