Coronary artery calcium-guided statin recommendations

Q: What did studies of coronary artery calcium-guided statin recommendations find?

Studies of coronary artery calcium-guided statin recommendations measured 4 outcomes, among them mortality, major adverse cardiovascular events and Statin initiation recommendations.

Coronary artery calcium-guided statin recommendations has been studied in 3 papers since 2026: 2 trials in people, 1 review; 3 in the past year. The newest story, Nov 9, 2026: “Calcium scans led to fewer statin recommendations in women”.
