Doctor Howard explained the left bundle branch block I had very well and organised tests quickly.
Doctor Howard helped me get my blood pressure under control and was very good at keeping my GP updated.
I had pains when visiting London and Dr Howard saw me within 2 days and arranged tests quickly for me - he was very thorough and kind.
I saw Dr Howard last week with chest pains and I've already had my tests and they are all good. Very reassuring.
Doctor Howard saw me promptly and arranged for an MRI scan very quickly. He explained the results very clearly afterwards and I felt very reassured.
I saw Doctor Howard for a heart check before my operation as my GP was worried about my ECG. He was very reassuring.
I had an appointment with Dr Howard by Zoom today and it was excellent.
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.
Dr James Howard is an outstanding cardiologist and cardiac imaging specialist whose expertise in cardiac MRI is second to none. As a colleague, I have always been impressed by his precision, depth of knowledge, and ability to deliver clear, clinically decisive interpretations even in the most complex cases.

CardiologistDr James Howard has been a colleague of mine since 2013. I can wholeheartedly attest to his skill, expertise, experience and knowledge and excellent, patient-focused approach. He is skilled in the management of cardiovascular conditions across the entire spectrum but has a particular interest in cardiac MRI, which is he acknowledged as a global leader in - with a large research program exploring the use of AI in this and other fields. I regular refer patients to him who speak very highly of him after his review.
