Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective is to estimate the impact of notification of primary care provider and patient of at least moderate incidental coronary artery calcification (CAC) on a prior non-gated chest CT on statin prescription rates at 4 months among patients without a clinical history of atherosclerotic cardiovascular disease not actively on statin therapy. This study will determine if notifying patients and their primary care clinician about an existing finding will influence shared decision-making around statins between patients and their primary care clinician.
