Dr Niket Patel

MBBS, BSC(1ST CLASS HONS), MD(RES), FRCP

Consultant Cardiologist

Dr Niket Patel is a friendly cardiologist that strongly believes in putting the patient at the centre of his decision making. He is an expert in managing patients with cardiac conditions and subspecialises in all aspects of complex interventional cardiology (angioplasty/stenting). He enjoys working with patients to find solutions to their symptoms, considering all possible options (conservative, medical, interventional and surgical).

Dr Patel studied medicine St George’s Hospital Medical School and completed his specialist training in cardiology and coronary intervention at Harefield Hospital and Oxford University Hospital. During this time he completed his doctoral thesis in the physiology of the coronary arteries in patients suffering from heart attack.

He is happy to see patients suffering from chest pain, breathlessness, palpitations, fainting or syncope, high blood pressure, patients concerned by their risk of heart disease (primary and secondary prevention), and heart valve disease or murmurs.
