What is cardiac CT?

Cardiac CT is now considered the first line investigation for patients who have chest pain.

A cardiac CT allows us to accurately model and assesses the arteries within the heart.

Supplementary information about cardiac CT

Here, we’ve summarised the most important points about cardiact CT

Cardiac CT is now considered the first line investigation for patients who have chest pain.

It is a method which uses x-rays and dye injected through a vein to create accurate detailed images of the arteries within the heart.

To get the best possible results, you may receive medication to slow down your heart rate (beta-blockers) and open up your arteries (GTN).

It is for patients with chest pain. It may be used to risk assess patients with high cholesterol.

Cardiac CT is not painful or uncomfortable in any way.

We will give you some medication, and then our radiographer will insert a small tube in your arm through which dye will be given during the test.

The CT scanner looks like a large polo mint with a bed in the middle. You’ll be asked to lie on the bed, and we will connect you to the scanner.

The scan itself lasts about 10 minutes.

Once the scan is complete, you’re typically monitored for approximately 15 minutes to half an hour to ensure that the effects of the medication has worn off and you are feeling well.

The most serious adverse effect is an allergic reaction to the dye, but this is rare. Some patients may experience an urge to pass urine once the dye is administered- this is quite normal.

Patients who experience chest pain, or are breathless may have narrowing within the blood vessels that supply blood to the heart.

The narrowing can be directly visualised with cardiac CT. Not only is it possible to see the extent to which the narrowing is obstructing blood flow in the heart arteries, it is also possible to see if there are early signs of disease (calcification) which may need treatment.

In addition, Cardiac CT allows us to assess all other structures within the chest like the lungs and food pipe which may be contributing to your symptoms.

The results are usually available the same day as the scan, and are reported by a cardiologist and a radiologist.

If the arteries are normal then usually no further action is needed. If there is evidence of mild narrowing within the heart arteries, the cardiologist will recommend medication to protect you from having a heart attack in the future.

If significant narrowing is identified, then you may be referred for some further test or interventions.

Cardiac CT is very safe.

The risks associated with cardiac CT are negligible. Cardiac CT involves ionizing radiation, so there is a theoretical risk of cancer, but this is very small. It is best that if you’re pregnant that you avoid a CT because it may harm your unborn child.

The main risks associated with cardiac CT are related to the dye. In a very small proportion of patients, they may experience a severe allergic reaction. However, the clinical team who look after you during the scan are trained to deal with any abnormal reactions to the dye.

It’s the wonderful words of our patients that make this job so worthwhile

Excellent bedside manner / patient care, thoughtful analysis and care. Great cardiologists!

J. T.

Dr Elghamaz was professional and compassionate in equal measure. He made me feel completely at ease and explained in detail exactly my situation answering all questions kindly and in a language I understood – not medical jargon. A complete gentleman under whose care I have every confidence.

R. R.

I called Dr Chahal’s secretary to get advice and an appointment for a stress echocardiogram as quickly as possible. Dr Chahal called me himself, to explain the procedure, and he managed to fit me in quickly, as I requested. On the day, he and his colleague carried out the test quickly, efficiently and kindly, explaining what they were doing and why. I would certainly recommend them as true healthcare professionals.

M. S.

Dr Elghamaz was very efficient, thorough and personable and made me feel at ease through through the process of undergoing several tests and then discussing results with myself and my husband to ensure we understood everything and were comfortable.

L. S.

Highly recommended. Professional, honest, put me at ease. Wonderful experience all around.

L. O.

Dr Elghamaz goes above and beyond for his patients. As well as being kind, he is extremely thorough, and I feel very comfortable knowing he is in charge of my care.

C. W.
Dr Sehmi is a fusion of the best of the old and new schools of medicine. Whilst reassuringly up to date with the latest evidence-based practice and comfortable with all the leading-edge technology of his field, he has always listened to my fears and given informed answers to all my questions.
S. L.

I had a really positive experience when I saw Dr Navin Chandra in his clinic. He took time to really listen to my problems and then explained what was wrong in simple terms. I had all my tests performed swiftly and have started to feel much better!

P.B.

Having been referred for specialist Cardiology review, I was very fortunate to be assigned Dr Sehmi as my Consultant. From the outset, his level of interest in my personal case has been exceptional. I have had several consultants for a variety of reasons over the years but Dr Sehmi is the first where a consultant has proactively followed up in between appointments to determine progress.

N. T.

I was admitted under Cardiology and Dr Chandra was my Consultant. He quickly got to the heart of the problem and he and his team didn’t miss a step. Later that evening Dr Chandra took the time to see my partner and his patience and knowledge gave us the answers to our many questions.
