About 1 in 3 people who die of coronary heart disease have no symptoms or warning before their heart attack or stroke. This study aims to find better ways to find people with coronary heart disease.

The study is by invitation only. The letter you received provides a unique code required for the registration process. Here’s how to register:

1. Watch the video, in its entirety, on the CorCal homepage.
2. Click the link on the right-hand side that states, “If you have received your invitation – Click HERE to enroll”.
3. After clicking the link, you will be directed to a website hosted by REDCap where you can enter your unique access code and complete your consent form online.
4. Upon completion of this form online, you will receive a message from the study team regarding next steps.

Your Intermountain doctor is taking part in the CorCal Research Study. We are reaching out to the patients that may qualify to participate in this study, which was created to help prevent heart attack and stroke.

This study will determine if adding a CT scan to the tests we already do will help discover more people that are at risk of a heart attack or stroke. Right now, the standard method, based on cholesterol levels, uses an atherosclerotic cardiovascular disease (ASCVD) risk score to predict how likely you are to have a heart attack or stroke. Doing a CT scan will create a coronary artery calcium (CAC) score. Looking at both scores together may identify people with coronary heart disease better than just using one score. It is also possible that doing another test and looking at another score will not make any difference. Our goal is to find the test or group of tests that are the best at finding people with a risk of having a heart attack or stroke, so they can be prevented.

Testing is different depending on the group you are placed in. You may be asked to take a lipid panel test to measure your cholesterol and/or do a CT scan to measure calcium. If you have already had one or both tests, your earlier results may be used. You will not need to pay for these tests. After testing, you will be asked to complete 5 short email surveys over the next 4 years.

Your time commitment will depend on the group you are assigned. You may be asked to complete all, some, or none of the following tests:

• Lipid Panel: 5 – 30 minutes
• CAC Scan: 45 – 60 minutes
• Questionnaires: 5 minutes

Based on your results, a heart specialist will send you and your doctor a report with their recommendations. Your report may include a suggestion to take a statin medication to help lower your cholesterol and your risk of coronary heart disease. We encourage you to speak with your doctor to find the right option for you.

You will be able to select your current Intermountain primary care doctor at the time of consent. Most of Intermountain Healthcare primary care doctors are participating in the CorCal study, but some are not. Giving us the name of your current primary care doctor is very important, since this will be the doctor we send results and recommendations to.

After you receive a report, you do not have to come back for additional testing.

However, you will be asked to complete a five-minute survey through your email three months later and once a year for approximately four years.
