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.

Dr Nigel G Stephens is a professional, friendly, and reassuring presence for his patients. He explains medical issues and next steps clearly, including specific procedures such as echocardiograms and stress ECGs.

Many patients seek his expertise for echocardiograms and managing conditions like atrial fibrillation.
If you are looking for a cardiology specialist who actually listens, see Dr Nigel Stephens. He is friendly and down-to-earth. I was worried a heart issue might side line my training, but Dr Stephens used his deep knowledge of cycling to keep me moving forward. As a masters cyclist, he completely understood my desire to keep racing as an amateur. He managed my health while fully supporting me to continue riding at my current level. It feels great to have a doctor who supports your athletic passion!"
Dr Steven’s was very personable and friendly from the moment he introduced himself. Once in his surgery he showed his thorough knowledge of my situation and his profession. He left me with a clear understanding of my options and whilst a little taken aback, I felt my life was in safe hands.
Dr. Stephens takes a careful, thoughtful and proactive approach to my care. He gives me a lot of confidence.

Mr Stephen’s has looked after me for nearly two decades.I am always confident that he will look after me.
I've seen Dr Stephens over the past 26 years and always found him to be professional, explain clearly his diagnosis and what he recommends as the right treatment. That was the same during my last appointment with him.
