Cardiac Check-up

A cardiac check-up is a structured set of tests that looks at the heart's structure, rhythm, pumping and blood supply, and at the factors that drive heart disease. It starts with a cardiology consultation about symptoms, family history, smoking, exercise, diet and medicines, followed by an examination and blood pressure measurement. Blood tests usually include cholesterol and other blood fats, sometimes lipoprotein(a), blood sugar and HbA1c, kidney function and thyroid function. A resting electrocardiogram records the heart's electrical activity, and an echocardiogram, an ultrasound scan of the heart, shows the chambers, valves and how well the heart pumps. An exercise stress test checks how the heart copes with effort. A coronary calcium score measures hardened plaque in the heart arteries, and CT coronary angiography shows narrowings directly. A 24-hour rhythm monitor or carotid ultrasound may be added when relevant.

A cardiac check-up is worth considering when your risk of heart disease is raised but you have no urgent symptoms. Common reasons include a parent or sibling who had a heart attack, stroke or sudden cardiac death at a young age, smoking now or in the past, diabetes, high blood pressure, high cholesterol, excess weight, kidney disease and a largely inactive life. Risk rises with age, so many men from about 40 and women from about 50, or after menopause, choose a heart assessment. People starting intense exercise or competitive sport, pilots and others with medical requirements for work, and people with occasional palpitations or breathlessness on effort may also benefit. Some tests are not useful for everyone: in people at low risk, scans can find borderline results that lead to unnecessary procedures. Chest pain at rest, fainting or sudden breathlessness need emergency care, not a planned check-up.

The visit usually begins in the morning with registration and fasting blood samples, followed by a consultation with a cardiologist who reviews your history and examines you. The resting electrocardiogram takes a few minutes with sticky pads on the chest. The echocardiogram is done lying on your side while a probe with gel is moved over the chest, taking about 20 to 40 minutes. For the exercise test you walk on a treadmill that gradually becomes faster and steeper while the heart tracing, blood pressure and symptoms are watched by a doctor; it usually lasts 10 to 15 minutes of effort. If a calcium score is planned, a quick CT scan without injection is taken while you hold your breath. CT coronary angiography needs a contrast injection through a vein and sometimes a medicine to slow the heart. The cardiologist then reviews all results with you and agrees the next steps.

Most adults can have a cardiac check-up, and the programme is adjusted to your age, risk and fitness. Tell the team in advance about any chest discomfort, breathlessness, palpitations, previous heart tests, stents or operations, and all your medicines, because some tests may need to be changed or postponed. Fast for about 8 to 12 hours before the blood tests if blood sugar and blood fats are included, drinking only water. Wear comfortable clothes and walking shoes for the treadmill. Some heart medicines, such as beta-blockers, are occasionally paused before an exercise test, but only on your cardiologist's advice. Before CT coronary angiography, avoid caffeine on the day, and tell the team about kidney disease, diabetes medicines such as metformin, asthma or any allergy to contrast. Bring previous electrocardiograms, echo reports and blood results, because comparing them over time is often more informative than a single reading.

There is no real recovery after a cardiac check-up: you can eat once the fasting samples are taken, and you return to normal activities the same day. After CT coronary angiography, drink plenty of fluids to help clear the contrast, and if you take metformin, follow the advice on when to restart it. Flying is usually fine the same or the next day if the results are reassuring. A practical plan is to arrive the day before, complete the tests in the morning, and keep a spare day in case the cardiologist recommends an additional test. If a significant finding appears, such as a blocked artery or a valve problem, the next step may be further tests or treatment, and the team will advise whether it is safer to arrange it during the same trip or at home. Ask for the reports, images and electrocardiograms in writing so your own doctor can follow your results over time.

The tests in a cardiac check-up are generally safe. An exercise test carries a very small risk of rhythm disturbances or chest pain, which is why it is supervised by a doctor with emergency equipment at hand. CT scans add a small radiation dose, low for a calcium score and higher for CT angiography, and the contrast can rarely cause an allergic reaction or affect the kidneys. The more common problem is uncertainty: an exercise test can be abnormal in a healthy heart or normal in someone with disease, and a CT scan can show small, harmless spots in the lungs that need follow-up. A borderline finding should lead to a considered discussion, not an automatic invasive procedure. A normal check-up lowers the short-term likelihood of significant heart disease but does not remove future risk. Most people leave with a clear risk estimate, cholesterol and blood pressure targets, and practical advice on exercise, diet and smoking.
