Dr Yousif Ahmad is a Clinical Research Fellow at the National Heart and Lung Institute, Imperial College London and Interventional Fellow at The Hammersmith Hospital, Imperial College Healthcare NHS Trust. 

He completed his undergraduate training at The University of Nottingham. In 2007 he was awarded a Bachelor of Medical Sciences (Honours) with a dissertation focussing on prognostic therapies for chronic heart failure, and in 2009 he went on to graduate with Honours and multiple distinctions. He subsequently undertook his initial postgraduate medical training in the West Midlands, and began to develop his research interests in Cardiology. Under the supervision of Professor Gregory Lip he published several first-author papers on stroke prevention in atrial fibrillation, and his work in this field has been cited by international guidelines. Parallel to this, he was awarded his Membership of the Royal College of Physicians in 2012.

In August 2013 he was appointed to the highly prestigious National Institute for Health Research (NIHR) Academic Clinical Fellowship in Cardiovascular Medicine at Imperial College London and also commenced his clinical training in Cardiology at Imperial College Healthcare NHS Trust. After two years of joint academic and clinical training in General Cardiology, he was appointed to the competitive Fellowship in Interventional Cardiology at The Hammersmith Hospital. During this time he developed his clinical skills in the invasive assessment and treatment of coronary artery disease as well as continuing his interest in academia under the supervision of Professor Darrel Francis.

In October 2016, he commenced his PhD under the supervision of Dr Sayan Sen. This work has focused on coronary flow in patients with severe aortic stenosis and coronary artery disease and has led to important advances in our understanding of the interaction between aortic valve disease and coronary artery disease. 

His research interests span all of Interventional Cardiology, with a particular emphasis on coronary physiology and the improvement of patient outcomes through tailored therapy.

His work has been recognised with multiple national and international prizes, most notably the Best Abstract/Young Investigator award at EuroPCR in Paris in May 2018, and the American Heart Association Scientific Sessions Samuel A. Levine Young Clinical Investigator Award in Chicago in November 2018.
