🌱 來自: noninvasive evaluation of CAD

Coronary artery calcium (CAC) score

• Quantifies extent of calcium; thus, estimates plaque burden (but not % coronary stenosis)
• CAC sensitive (91%) but not specific (49%) for presence of CAD; high NPV to r/o CAD
• In intermediate-risk or selected borderline-risk adults (ie, 10-year ASCVD risk of 5–20%), if decision about statin remains uncertain, reasonable to use CAC score to help guide
