Meet Dr OA – Consultant Interventional Cardiologist

I am Dr OA, a Consultant Interventional Cardiologist with extensive experience in the prevention, diagnosis, and treatment of heart disease, particularly coronary artery disease.

I graduated over 25 years ago with an MBBS from Guy’s, St Thomas’ and King’s School of Medicine and Dentistry, and later completed a Doctorate of Philosophy (PhD) in Medicine at Imperial College London in 2007. My doctoral research focused on pulmonary hypertension, a complex and evolving condition within cardiovascular medicine.

I became a specialist cardiologist in 2013, and since then I have remained at the forefront of evidence-based cardiology, continually adopting the latest advances in heart investigations, medications, and interventional treatments. My approach combines scientific excellence with compassionate, patient-centred care, ensuring each patient receives clear explanations, personalised treatment plans, and the highest standard of cardiac care.
