About Dr. James Howard

Dr James Howard is a Consultant Cardiologist and Clinical Academic with expertise in general cardiology and cardiac imaging. He holds a British Heart Foundation Intermediate Fellowship at Imperial College London and sees patients at OneWelbeck, Hammersmith Hospital and Charing Cross Hospital.

Dr Howard completed his medical training and specialist cardiology training in the UK and combines clinical practice with an active academic and research role. His clinical work covers the assessment and management of common cardiology presentations, including chest pain, breathlessness and palpitations, as well as the investigation and long-term management of cardiovascular risk factors such as hypertension and hypercholesterolaemia. He has a particular interest in advanced cardiac imaging, including cardiac MRI.

In parallel with his clinical work, Dr Howard has a background in computer science and artificial intelligence. He has developed AI-based tools designed to improve the speed and accuracy of cardiac MRI scanning, with applications now used in clinical settings. His work in artificial intelligence has received international recognition, including awards supported by Facebook and Microsoft.

Dr Howard led the SAMSON Trial, published in the New England Journal of Medicine, which examined statin-associated side effects and their impact on patient experience. His research continues to focus on clinically relevant questions that inform shared decision-making and evidence-based cardiovascular care.

Doctor Howard listened to all my concerns, despite the fact I had to rearrange my appointment last minute. He used a CT scan to show me my pains weren't anything dangerous.
