Nigel Stephens was recruited from Cambridge University, where he was a Lecturer in Medicine, to lead a newly built Cardiac Centre in Northwick Park Hospital over 20 years ago. This centre became successful and high-performing, with excellent outcomes. He brings these same qualities to his private practice, providing accessible and personalised care for people with heart disease. He is particularly committed to helping patients return to an active life following episodes of serious illness, so they can enjoy the benefits of physical activity and exercise.
Dr. Stephens oversees all aspects of cardiology care for patients 16 and older, including valvular heart disease, hypertension, cardiomyopathy, heart failure, and cardiac rhythm abnormalities. He also offers interventional procedures such as coronary angioplasty and stenting. He has strong and reliable communications with a group of colleagues who are based at Northwick Park Hospital; referrals to specialist cardiac surgery or electrophysiology services are discussed weekly in a meeting that Dr. Stephens chairs himself.
Dr. Stephens provides comprehensive care for patients with complex cardiovascular conditions, including the use of rotational atherectomy and mitral balloon valvuloplasty. He has extensive experience in managing cardiac problems in athletes, having helped establish a sports cardiology service at the Olympic Medical Institute. Over 10 years, this team saw more than 1,000 athletes referred with cardiac issues. Dr. Stephens is particularly interested in assessing apparently abnormal findings in athletes' hearts and determining whether it is safe for them to continue playing competitive sports if they have established heart disease. This has become an increasingly complex issue as common cardiovascular diseases tend to occur later in life while many people still wish to take part and compete in sporting activities.
