Yes, a heart assessment can still be worth it if you already take a statin or blood pressure medication, but for a narrower reason than most people expect. It will not tell you whether to stay on your medication. It can show whether the risk that remains on treatment is well controlled, and whether anything has gone unmeasured.
Cardio Res-Q offers two assessments: the Comprehensive Assessment at $775 and the Enhanced Assessment at $999. If you are already treated, the lab work is usually the more informative part. The calcium scan in the Enhanced Assessment is harder to interpret once you are on a statin, for reasons explained below.
Key takeaways
- An assessment can still be worthwhile on a statin, mainly to check whether your remaining risk is well controlled.
- The assessment cannot decide for you whether to keep taking your medication.
- For people already treated, the lab work, including ApoB and Lp(a), is usually the more informative part.
- A calcium score is harder to read on a statin, because the score can rise without the disease getting worse.
- Never stop or change a medication because of a test result, and take any change to your prescriber.
A statin lowers risk, it does not remove it
Statins reduce the chance of a heart attack or stroke. They do not bring it to zero. Doctors call what is left over residual risk.
Part of that residual risk can hide behind a good LDL cholesterol number. In a study of more than 13,000 people taking statins, high ApoB was linked to a higher risk of heart attack and death, while high LDL cholesterol was not.1 ApoB counts the particles that carry cholesterol into the artery wall, so it can stay high when LDL cholesterol looks fine. Our guide to the ApoB test explains why the two can disagree.
Other parts of residual risk have little to do with cholesterol: blood pressure, blood sugar, inflammation, smoking, weight, sleep and inherited factors.
What an assessment can show when you are already treated
Both Cardio Res-Q assessments include the same lab panel and clinical evaluation. For someone on medication, the useful questions are these:
- Is your ApoB where your clinician wants it? This is a direct check on whether your current treatment is doing enough.
- What is your Lp(a)? Lp(a) is inherited and is measured once as a baseline. Statins do not lower Lp(a), and pooled trial data show they raise it slightly.2 No approved drug lowers Lp(a), and the clinic does not treat it. A high result still matters, because it tells your doctors how firmly to manage everything else.
- Is there ongoing inflammation? The panel includes hs-CRP and homocysteine.
- How is your blood sugar control? Insulin, glucose and A1c can point to insulin resistance, which adds to heart risk whatever your cholesterol is.
- What is your blood pressure pattern? The evaluation reviews blood pressure patterns along with sleep, stress, nutrition, exercise and family history.
The program page says many patients use the evaluation to see whether their current regimen is adequately controlling their risk. That is a fair description of what it can do.
Why a calcium score is harder to read on a statin
The Enhanced Assessment adds a coronary artery calcium (CAC) score and a CIMT ultrasound. If you take a statin, read this section before you choose it.
Statins change plaque. An analysis of eight trials that used ultrasound inside the coronary arteries found that statins promote calcification of plaque, even while high-intensity statins shrink it.3 The authors suggest this may be one way statins stabilize plaque. So a calcium score can go up on a statin without meaning that the disease is getting worse.
A later study of repeat heart CT scans reached a practical conclusion: in people taking statins, a rising calcium score reflected growth in calcified plaque only, not in soft plaque, so repeat scores need to be interpreted differently.4 A first calcium score still shows how much calcified plaque you have. What it cannot do on a statin is work as a simple progress report.
If you have had a calcium scan elsewhere, bring the report. The clinic accepts outside calcium scores, and a score keeps clinical value for several years as a baseline. The scan is done at an outside imaging facility and is a separate self-pay study, typically $100 to $200.
As for CIMT, US guidance from 2013 does not recommend it routinely for predicting a first heart event, and carotid plaque predicts risk better than wall thickness. Our CIMT guide covers its limits.
What an assessment cannot change
An assessment produces information and a plan. It does not change your prescriptions by itself.
- Do not stop, skip or change the dose of a statin or blood pressure medication because of a test result or anything you read here.
- Any change to a medication goes through the clinician who prescribes it.
- Cardio Res-Q is not a replacement for your cardiologist or primary care doctor. The clinic is happy to share your results and work alongside them.
- No test can promise that you will not have a heart attack.
You will fast for 10 to 12 hours before the blood draw. Ask our team, or your prescriber, whether to take your morning medications before the draw. Do not skip a dose on your own.
Which assessment makes sense if you are on medication
The $775 Comprehensive Assessment answers the questions in the list above. For many people who are already treated, that is the main value.
The $999 Enhanced Assessment may make sense if you have never had a calcium score and your clinician would use the result. If you already have a recent score, or you are mainly interested in whether your medication is working, the imaging adds less. See Comprehensive vs. Enhanced for a fuller comparison.
If you have diagnosed heart disease and want treatment rather than a risk evaluation, your cardiologist is the right place to start.
Next step: how to book
Book either assessment from the Cardio Res-Q program page. Bring a list of your medications and doses, and any earlier lab or scan reports you have. The assessment is complete and standalone, and ongoing care with the clinic is optional.

Three quick questions about the risk factors we screen for. Your answers stay between you and the clinic.
Frequently asked questions
Should I stop my statin before the assessment?
No. Keep taking your medications as prescribed. The point of testing while you are on treatment is to see how well that treatment is controlling your risk. Only your prescriber should change or pause a medication.
My calcium score went up on a statin. Is the statin failing?
Not necessarily. Statins promote calcification of existing plaque, so a higher score on treatment does not by itself mean the disease is getting worse. Take the result to the clinician who prescribes your statin and ask how it fits with your ApoB and other numbers.
My LDL is at goal. Why measure ApoB?
Because the two can disagree. In people taking statins, a high ApoB has been linked to higher risk even when LDL cholesterol was low. If your ApoB is also at goal, that is reassuring. If it is not, your prescriber has something specific to act on.
Will the clinic change my medication?
The assessment gives you a personalized plan and a full explanation of your results. The clinic prescribes statins and non-statin medicines case by case, so any change would be discussed with Dr. Varano. It can also share your results with your cardiologist or primary care doctor. Do not change a medication on your own.
