Private Cardiology Clinic London

A lot of the uncertainty around heart disease and risk can be addressed with state of the art investigations, all available at our Cardiology Clinic, at 9 Harley Street.

London Cardiology Clinic

Heart disease remains the biggest cause of death and disease in the developed world, so it makes sense for everybody to undergo cardiac screening. At our London Cardiology Clinic, we deliver the best lifestyle advice, screening, preventative therapies, investigations and when necessary treatments for specific cardiac conditions to optimise long term health and quality of life.


Heart conditions we treat

One of the most common cardiovascular issues that a lot of people suffer from is heart disease and coronary heart disease. Our expert team can help you treat this issue with medications and treatment. There are many other common heart conditions we treat including: 

  • Heart disease
  • Palpitations
  • Heart valve disease
  • High blood pressure
  • Chest pain concerns

These are just a few of the issues that we see on a regular basis, but our expertise goes far beyond this list. Whether you are worried about cholesterol and stress or you are thinking about having a pacemaker installed, we are here to help you. 

Heart conditions we treat

Diagnostic Cardiology Tests

At our London private cardiology clinic, we offer a range of different cardiology tests to ensure that we precisely identify the issue that you are dealing with. Our experts offer same-day diagnostic imaging and screening to help us diagnose, evaluate, manage and treat cardiovascular conditions quickly and effectively.

Our state-of-the-art technology at 9 Harley Street means that you do not need to go elsewhere for treatment or medication, as we offer the following tests in-house:


An ECG (electrocardiogram) is one of the most basic cardiac investigations and involves putting stickers (electrodes) on the skin to detect the electrical impulses of the heart.
It is entirely painless and can often tell your cardiologist basic information about the rhythm and condition of your heart.

24 Hour Blood Pressure Monitor

A 24 hour ambulatory blood pressure monitor (ABPM) measures your blood pressure while you go about your normal daily life. It is measured over a period of up to 24 hours.

An echocardiogram is a type of ultrasound scan looks directly at the structure of the heart, its chambers and valves. It assesses the pumping power of the muscle, and how well the valves function. It is used to help diagnose various heart conditions such as heart failure, congenital heart disease, cardiomyopathy, and endocarditis.

Exercise Stress Test

The exercise test allows the cardiologist to see how the heart performs under load. Although the exercise test has some limitations it can be useful in screening, assessing exercise capacity, in the investigation of patients with chest pain and for some other indications such as heart rhythm problems.

Stress Echocardiogram

Whilst the CTCA scan and coronary angiogram gives anatomical information about the coronary arteries and any possible narrowing, stress echo looks at the functional performance of the muscle of the heart and by implication the coronary blood supply to the heart.

CT Coronary Angiogram

CT Coronary Angiography (CTCA) is an imaging test that uses an X-ray machine to produce detailed images of the heart and surrounding blood vessels. It is an effective test to check for evidence of coronary artery disease which can cause heart attacks or angina.

Cardiac MRI

Magnetic resonance imaging (MRI) of the heart is non-invasive, and allows doctors to better determine the presence of certain diseases that may not be as easily seen with other imaging methods such as x-ray or ultrasound.

MRI of the heart and surrounding structures can be used not only to assess the function of the heart but also major vessels, and other important structures such as the sac around the heart and other organs e.g kidneys and adrenal glands.

AAA Screening

Screening for Abdominal Aortic Aneurysm (AAA) is used to check for abnormalities in the aorta, the main blood vessel that carries blood away from your heart to the rest of your body.

It is extremely important to continually check and monitor Abdominal Aortic Aneurysm, as these can get bigger and potentially burst.

Carotid Artery Scanning

Ultrasound of the carotid arteries (the arteries in the neck supplying blood to the brain) is undertaken for two reasons.

Firstly, in patients who have had a stroke or transient ischaemic attack (TIA) or in whom there is a clinical suspicion of problems with blood flow to the brain, an ultrasound or ‘carotid Doppler’ may be recommended. This is to look for severe narrowing of the arteries that might require treatment with surgical ‘endarterectomy’ or stenting.

Secondly for screening purposes.  The carotid arteries are very superficial and represent a part of the cardiovascular system which is very easy to access with ultrasound.

Cardiac and Aortic MRI

MRI is an excellent test for evaluating the heart muscle as well as the aorta (the main blood vessel extending from the heart into the chest and abdomen) and is often used to exclude or monitor aortic aneurysm. MRI can also be very useful in the investigation of high blood pressure (hypertension).

Aortic Aneurysm Monitoring

If you have already been diagnosed with either an Aortic Abdominal Aneurysm (AAA) or a Thoracic Abdominal Aneurysm (TAA), we offer an expert-led MRA scanning service to monitor the progress of your aneurysm and ascertain whether surgery is required.

Aortic aneurysms usually only require surgery if they become very large and at risk of rupture. It is therefore recommended to have an MRA scan, which is a type of MRI that looks specifically at the aorta, six months after your diagnosis and then regularly from then on.

Heart Health Check

We believe the key to successful cardiac screening is to take a patient centred approach. When you come to our London Cardiology Clinic, your Heart Health Check will start with an assessment with one of our expert cardiologists.

Your cardiologist will advise you on which investigations and tests are appropriate for you. These could include an ECG, echocardiogram, blood tests, CT coronary angiogram or calcium score. Your tests will be arranged on the same day if possible.

You will then come back to the cardiology clinic for a follow up consultation, where your cardiologist will explain the test results to you and the implications for your future health. They will also advise on recommended treatments and lifestyle changes.

Heart health is a life-long priority so your cardiologist will guide you through a long term plan.
