Obtaining coronary artery calcium scores can prove valuable in determining which of your patients might benefit from statins and which won't. This German study included 3745 individuals without known heart disease and who were not on lipid-lowering meds. Researchers calculated both their cardiac risk scores using current algorithms and the coronary artery calcium scores from cardiac CT.
During the 10-year follow-up period, patients with baseline coronary artery calcium scores of 400 or higher had a cardiac event rate of 12.6%. But when baseline scores were less than 100, the chance of a cardiac event decreased to just over 3%.
This means that you may be able to better risk-stratify those patients who qualify for a statin per guidelines but who have a low coronary artery calcium score—especially those with a zero score. They may not need a statin after all.
