About this trial

This is an interventional other trial for Atherosclerotic Cardiovascular Disease focused on measuring Coronary Calcium, Statin, Non-gated Chest CT

Eligibility Criteria

18 Years - 85 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Non-gated chest CT between 2014-2019
  • The presence of CAC confirmed by manual review by an experienced radiologist
  • Stanford affiliated primary care provider or endocrinologist for Stanford healthcare system patients and VA primary care provider for VA patients with at least 1 encounter since 2018

Exclusion Criteria:

  • Current or prior statin or PCSK9 inhibitor therapy
  • Prior diagnosis of ASCVD (coronary artery disease, peripheral arterial disease, cerebrovascular disease, coronary/peripheral revascularization)
  • Prior coronary imaging (cardiac CT, invasive coronary angiography)
  • Dementia
  • Metastatic cancer or active cancer undergoing chemotherapy
  • History of medical nonadherence

Sites / Locations

  • Stanford Hospital & Clinics

Notification

Usual Care

Arm Description

Patients randomized to notification will receive a message sent by either the electronic health record (EHR) patient portal or postal mail that will inform them of the CAC identified on their previous chest CT. It will provide an overview of CAC, an image of their chest CT, and a recommendation that they discuss this finding with their clinician. These clinicians will be notified of these findings via an earlier EHR message. Any treatment decisions will be made by the patient and their clinician. Patients randomized to notification who are not prescribed a statin medication and do not have a documented discussion regarding statin therapy within three months will be sent a second message at that time. Their primary care providers will receive a second EHR message concurrently.

Both arms have previously had their CT scans reported according to standard clinical practice. This may include notification of the CAC in the imaging report. The usual care arm will not receive any additional notification beyond this standard of care during the project.

5. Study Description

Brief Summary
This is a multi-center, randomized quality improvement project. At least 200 statin-naïve patients without a history of atherosclerotic cardiovascular disease with incidental coronary artery calcium (CAC) on a prior non-gated chest CT will be enrolled across the Stanford Healthcare System and the Palo Alto Veteran's Affairs Healthcare System. Patients will be randomized in a 1:1 fashion to notification or usual care arms. The primary aim of this project is to estimate the increase in 6-month statin prescription among statin-naïve patients without a history of atherosclerotic cardiovascular disease with incidental CAC on a non-gated chest CT who are randomized to receive notification of their findings vs. usual care.
