Krishna is a highly accomplished, award-winning Cardiologist who has an international reputation in heart coronary artery disease. He is an Interventional Cardiology Consultant at Barts Heart Centre in London, UK and a Senior Clinical Lecturer at The William Harvey Research Institute at Queen Mary University of London (UK). He is also the clinical lead for Cardio-Renal Medicine at both The Royal London Hospital and St. Bartholomew’s Hospital, where he regularly reviews patients with end stage renal failure and patient with cardiology symptoms waiting for renal transplant. He also chairs the Cardio-Renal MDT and attends the Pre-Transplant Renal MDT at Barts Health NHS Trust and Co-Chairs the National Cardio-Renal Clinical Study Group.
He works in close collaboration with General Practitioners, as well as kidney and diabetes specialists, to deliver coordinated, multidisciplinary care and achieve the best possible outcomes for patients with complex and co-existing conditions.
Beyond technical excellence, Krishna adopts a genuinely holistic approach to treatment, recognising that medical conditions exist alongside the broader context of a patient’s life. He carefully tailors’ management strategies to align with individual lifestyles, preferences, and values. To support this, he utilises the latest guideline-recommended cardiac investigations alongside meticulous clinical assessment, ensuring that patients are fully and appropriately evaluated.
Krishna completed medicine at Barts School of Medicine with two distinctions and an intercalated degree in Molecular Therapeutics (1st Class Hons). He completed a prestigious NIHR Academic Clinical Lectureship at QMUL and Barts following the completion of his PhD and completed training in Interventional Cardiology alongside continuing translational and clinical research. His research and clinical expertise has results in over 100 International and National prizes and honours. He was appointed as an Honorary Consultant in Interventional Cardiology at St. Bartholomew’s Hospital in 2024.
Krishna’s clinical expertise was further refined through the completion of a prestigious cardiology elective at Harvard University, where he was exposed to world-leading practice and innovation. The exceptional mentorship he received at both Barts and Harvard Medical Schools has shaped the benchmark for the high standard of patient-centred care he consistently strives to deliver. His practice is firmly grounded in evidence-based medicine, ensuring that patients benefit from the most up-to-date, validated advances in cardiovascular care.
In addition to winning many prizes, he warded the Vogt Prize for the best National PhD in Clinical Pharmacology (warded by BPS) and a finalist at the Royal Society of Medicine Gold Medal 2023 as well as a finalist for BCIS Young Investigator 2015.
Krishna is an internationally recognised expert in interventional cardiology and intracoronary imaging (IVUS and OCT), an advanced technique which can help guide Cardiologists on when and where a coronary stent is needed as well as how to implant and optimise the stent. Krishna is deeply committed to improving patient outcomes through the development, evaluation, and clinical application of innovative medical technologies. He has led and contributed to ground-breaking research in invasive cardiovascular technologies that has significantly influenced contemporary practice and translated into improved treatment strategies for patients worldwide. Recent high-quality research has established intracoronary imaging as an emerging ‘benchmark’ for the optimisation of coronary stent implantation, with several large-scale international trials currently underway. Krishna is actively involved in the conception, design, and delivery of a number of these complex multicentre studies, serving as principal investigator. In addition, Krishna has expertise in the use of CT coronary angiography to help diagnose patients efficiently and without the need for invasive procedure and is part of the CTFFR MDT at Barts Heart Centre.
Krishna has over 130 high impact publications, including the Circulation, European Heart Journal, the Journal of American College of Cardiology, the New England Journal of Medicine and the Lancet. Krishna has designed and led influential research studies and contributed to landmark international trials that have reshaped interventional cardiology practice globally. He has also presented at over 50 International Cardiology conferences. Other research interests include conducting interventional clinical trials.
He is recognised globally as a key opinion leader in his field and this is reflected in numerous roles in multicentre clinical trials, invited lectures at major conferences and also as an editor/reviewer of numerous journals including JACC, EHJ and Circulation. He is also on the editorial board for several high impact journal including JAHA. Furthermore, in recognition of his expertise, he is frequently invited to speak and serve as faculty at major international scientific meetings, including EuroPCR and Cardiovascular Research Technologies (CRT).
He completed a PhD in translational medicine at Queen Mary University of London funded via a prestigious NIHR doctoral research fellowship where he investigated the impact of dietary nitrate (in the form of beetroot juice) on renarrowing within stent. This work led to interviews with a number of National Newspapers (including Daily Express and The Sun) and multiple publications in high impact journals (including Lancet eClinicalMedicine). Furthermore, he has presented his research at the leading national and international cardiology conferences around the world, including the European Society of Cardiology (ESC), Transcatheter Cardiovascular Therapeutics (TCT) and EuroPCR.
