For many men, the first sign of heart disease is a heart attack. Here's what CAC scoring and CT coronary angiography actually show, who they're for, and how a Quantum doctor can review your risk and refer you where a scan is warranted.
The short version. Cholesterol and blood pressure tell you about risk. A heart scan can show whether disease is actually there. Not every man needs one, and a CT scan needs a doctor's referral. This consultation is where that decision gets made, with someone who has looked at your whole picture.
Book a Men's Health & Prevention consultation and tell us heart health is your focus. Your doctor reviews your existing results, blood pressure, ECGs or scans before you meet, assesses your cardiovascular risk in plain English, and refers you for a CAC score, CT coronary angiogram or advanced bloods such as ApoB and Lp(a) where clinically appropriate.
€199 with your own recent bloods · €349 with Quantum-arranged bloods. Scan fees are paid separately to the imaging centre, and your doctor will explain the options first.
A heart-focused consultation is for men who feel well but want to know their risk, and for men who already have results and aren't sure what they mean. It's particularly worth considering if you:
Chest pain, pressure or tightness, breathlessness, or fainting need urgent attention, not a booked consultation. Call 999 or 112, or contact your GP straight away.
Prevention works best as a process, not a one-off test. When heart health is the focus of your consultation, your doctor follows the same five steps.
Symptoms, concerns, lifestyle, medication and family history.
Blood pressure and bloods, including ApoB, Lp(a) and HbA1c where useful.
CAC score or CT coronary angiogram, only where it will change what you do.
Lifestyle priorities and, where appropriate, treatment such as a statin.
Re-measure at the right intervals so you can see it working.
A coronary artery calcium (CAC) score is a short, non-contrast CT scan of the heart. There's no injection and no preparation beyond lying still for a few minutes, and it uses a low radiation dose. It measures calcified plaque in the arteries that supply your heart, reported as a number (the Agatston score).
The score is most useful when your risk is borderline or intermediate and the decision about treatment, such as whether to start a statin, could go either way. What it can't see is softer, non-calcified plaque, which is one reason a score of zero isn't a free pass for everyone.
A CT coronary angiogram (CTCA) is a more detailed CT scan of the heart arteries, taken after an injection of contrast dye through a vein in your arm. You may be given medication beforehand to slow your heart rate so the images are sharp. It shows both calcified and non-calcified plaque, and whether any artery is narrowed.
Because it involves contrast and a higher radiation dose than a calcium score, CTCA is used where there's a clear reason: to investigate symptoms, when the risk picture is high or unclear, or to look further after a high calcium score. Your doctor will check your kidney function and any allergies before referring you.
| CAC score | CT coronary angiogram | |
|---|---|---|
| What it shows | Calcified plaque, as a score | Calcified and soft plaque, and any narrowing |
| Injection | None | Contrast dye into a vein |
| Radiation | Low dose | Higher than a CAC score |
| Typically used for | Refining risk in men without symptoms | Investigating symptoms, higher or unclear risk, or a high CAC score |
| Needs a referral | Yes | Yes |
Some men are better served by bloods and a conversation than by a CT scan. If your risk is clearly low, or clearly high enough that treatment is already indicated, a scan may not change anything, and we'll tell you so. Scans can also find things unrelated to the heart that need follow-up. We'll talk through the benefits and downsides before any referral.
Your results come back to your doctor. You can book a follow-up consultation (the cost is confirmed before you book) to go through them by video and agree a plan: lifestyle priorities, treatment where appropriate, a referral to a cardiologist if anything needs a specialist's opinion, and when to re-check. With your permission, we'll keep your GP informed.
No. You can book a Men's Health & Prevention consultation directly. If a scan is appropriate, the referral comes from your Quantum doctor.
CT scans in Ireland need a referral from a doctor who has judged that the scan is justified for you. That's part of what a Men's Health & Prevention consultation is for, and it means someone is there to interpret the result with you afterwards.
Prices vary between imaging centres and between CAC and CTCA. Your doctor will give you options and expected costs before anything is booked. Some health insurance plans contribute towards scans, so it's worth checking your policy.
A high score is information you can act on. Your doctor will explain what it means, agree a plan to lower your risk, and arrange further tests or a cardiology opinion where needed.
Yes. Upload the report when you book and your doctor will go through it with you, alongside your other results.
