Dr Fiyyaz Ahmed-Jushuf is an Interventional Cardiology Registrar and Doctoral Research Fellow at the National Heart and Lung Institute (NHLI), Imperial College London. His research focuses on coronary physiology, angina, and placebo-controlled cardiovascular trials, with a particular interest in the relationship between myocardial ischaemia and symptoms in stable coronary artery disease.

He is part of the ORBITA research group at Imperial College London and has contributed to several landmark placebo-controlled interventional cardiology trials, including ORBITA-2, ORBITA-COSMIC, ORBITA-STAR, and ORBITA-FIRE. His work has been published in leading journals including the New England Journal of Medicine, The Lancet, Circulation and JACC.

Dr Ahmed-Jushuf is supported by a UKRI/MRC Clinical Research Training Fellowship and is the lead investigator of ORBITA-FIRE (Finding the Invasive Threshold for Symptom Relief in Exertional Angina), the first double-blind, placebo-controlled study to define personalised physiological thresholds for angina using invasive coronary physiology during exercise.

Alongside his academic work, his clinical interests include imaging- and physiology-guided percutaneous coronary intervention, complex coronary intervention, and medical education. He was awarded the British Cardiovascular Intervention Society (BCIS) Young Investigator of the Year award in 2026.
