Effectiveness of a Proactive Cardiovascular Primary Prevention Strategy, With or Without the Use of Coronary Calcium Screening, in Preventing Future Major Adverse Cardiac Events

This is a randomized, open-label, pragmatic study designed to assess the effectiveness of coronary calcium screening. Patients who provide consent, and are eligible, will be randomized 1:1 to receive statin recommendation based on coronary calcium screening results or standard risk assessment results using the American Heart Association/American College of Cardiology (AHA/ACC)-recommended pooled cohort equation. Management of all participants will be done through their primary care physicians/clinicians and their qualified delegates who will receive education and training from the Principal Investigator and/or his delegate about the two treatment strategies. The current National guidelines group will be managed following the AHA/ACC guidelines for statin initiation and follow-up. The coronary artery calcium (CAC) group will undergo coronary artery calcium screening and will receive a statin recommendation based on the proposed CAC cardiovascular (CV) risk algorithm. All subjects will be asked to complete the Intermountain Statin Adherence Questionnaire (ISAQ) at 3 months after recommendation (+ 60 days) and then annually thereafter (within +/- 60 days of the anniversary date of recommendation). All subjects will remain under the usual care of their primary care physicians and will be followed by the study team via their electronic health records (EHR) for approximately an average of 4 years following the subjects' anniversary date of recommendation, but until the target primary endpoint event rate is met. All enrolled subjects will be followed for outcomes and this will be completely done by electronic medical records query. Other than the time point to obtain agreement for study participation and to perform the CAC screening and/or lipid panel, there will be no other study-specific clinic visits required. Further, there will be no other treatments or procedures required for this study. After about the first 600 patients are enrolled, an interim meeting will occur to evaluate entry criteria and size to determine if any modifications to the protocol should occur.
