Heart failure is a common but serious heart condition where the heart becomes less effective at pumping blood around the body. This can lead to symptoms such as shortness of breath, fatigue, swollen ankles, and persistent coughing, especially when lying down. Despite its name, heart failure does not mean the heart has stopped working—it means it needs support to work more efficiently. Causes of heart failure include high blood pressure, coronary artery disease, heart valve problems, or a previous heart attack. Early diagnosis and specialist treatment can make a significant difference to quality of life and long-term outcomes. If you’re experiencing symptoms or have concerns about your heart health, Dr. Anna Marciniak, expert cardiologist in London, offers rapid access to private heart failure assessment and treatment at her Surrey clinic.

An echocardiogram is a non-invasive heart scan that uses ultrasound waves to create detailed images of your heart's structure and function. It allows cardiologists to assess how well your heart is pumping, how your valves are working, and whether there are any abnormalities in the heart muscle or chambers. Often referred to as an “echo,” the test is completely painless and typically takes 20–40 minutes. At London Heart Group, we offer private echocardiograms in London, with expert analysis provided by our experienced cardiology consultants—often on the same day. This test is a key part of diagnosing conditions such as heart failure, valve disease, cardiomyopathy, and heart murmurs.

A cardiac MRI is a safe, non-invasive scan that uses powerful magnets and radio waves to create detailed images of your heart. It helps doctors assess heart structure, function, and blood flow with exceptional clarity. You may be referred for a cardiac MRI if you're experiencing symptoms like chest pain, shortness of breath, or palpitations, or if you have known or suspected heart disease, such as cardiomyopathy, heart valve problems, or previous heart attacks. It’s especially useful when other tests like an echocardiogram or ECG don’t provide enough information. A cardiac MRI provides a clearer picture of your heart, helping your cardiologist make the most accurate diagnosis and plan the best treatment for you.

A stress echocardiogram (or stress echo) is a specialised ultrasound test used to assess how well your heart functions under physical stress. It combines a standard echocardiogram with either exercise (usually on a treadmill or bike) or a medication that simulates the effects of exercise if you’re unable to exert yourself physically. The test helps detect conditions such as coronary artery disease, where the heart may not receive enough blood during exertion. By comparing heart images at rest and under stress, your cardiologist can identify areas of reduced blood flow or abnormal heart function. At London Heart Group’s Spire St Anthony clinic, we provide expert private stress echocardiograms, with consultant-led interpretation and tailored follow-up care.
