Calcium score tests rarely change heart-risk decisions, study finds
A JAMA study of about 6,000 adults shows the PREVENT heart-disease risk calculator alone accurately predicts near-term events for most people; adding a coronary artery calcium (CAC) score provides little extra value except as a tiebreaker for those at borderline/intermediate risk, where a higher CAC score may influence statin decisions. For high- or low-risk individuals, CAC typically wouldn’t alter treatment, suggesting CAC scans should be reserved for select middle-risk patients and discussed with a clinician.
