What happens after I'm enrolled into the study?

After you complete the consent form, you will be randomly assigned to one of two groups and informed of what testing you may need to complete.

GROUP 1: Your risk for coronary heart disease will be evaluated using American Heart Association (AHA) standards. You may be asked to get a lipid panel, at no cost to you, to test your cholesterol. Find a CorCal lab location near you. If you’ve had a lipid panel within the last three years, the study will use those results in place of additional testing.

Time requirements: 0 - 30 minutes

GROUP 2: You will be asked to get a CAC scan and a lipid panel, at no cost to you. For the lipid panel, please find a CorCal lab location near you. If you have had a lipid panel within the last three years, the study will use those results in place of additional testing. The scan takes about an hour. Your risk is evaluated based on the results of both of these tests.

Time requirements: 1-1.5 hours


Why was I contacted for this study?

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.


I don't currently have any heart issues that I'm aware of. Is this study for me?

This study’s goal is to identify people that have plaque in the blood vessels that feed their heart. This is known as coronary heart disease. People with coronary heart disease are at a higher risk for a heart attack or stroke. People may or may not know that they are at risk. The tests may help discover heart problems so that events like a heart attack can be prevented.

Why is this study important?

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.


What is this study about?

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.

Can I sign up if I have not received an invitation letter from the study?

No, this study is by invitation only. If you did not get a letter or email, you will not be able to join this study. You may get a letter if your doctor is participating in this study and you meet the study guidelines for age, sex, etc.


What will I be asked to do?

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.

What is the time commitment for participating in the study?

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

Will I be able to choose which group I'm assigned to?

No. When you sign up, you will be randomly assigned to a group We have no control over what group each patient is assigned to.


What if the primary care doctor listed on my letter is not my current provider?

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.


What happens after testing is complete?

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.


Is there any follow up?

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.


What are the risks?

This is a low-risk study.

  • A CT scan will expose you to a small dose of radiation. The risk that comes with this dose is very low.
  • No special dyes or other substances are needed for the CT scan.

What are the benefits?

  • You will help the medical community develop better preventative practices while testing for heart disease.
  • A cardiac specialist will oversee the evaluation of your heart health, along with your primary care provider.

What are the costs?

There is no cost to you for participating in this study. Intermountain Heart Institute will cover all study-required tests, such as the CT scan and/or lipid panel.

If you have any follow up doctor’s appointments or prescriptions due to the study recommendation, you will be responsible for the cost of those.
