Dr Krishnaraj Rathod

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). His clinical interests are within complex coronary intervention, particularly complex high risk interventional procedures (CHIP) cases. He has an academic interest in observational studies and outcomes following percutaneous coronary intervention and has over 130 peer-reviewed publications and has over 250 abstracts. He has also presented at over 50 international cardiology conferences. Other research interests include conducting interventional clinical trials. He completed a PhD in translational medicine at Queen Mary University of London, funded via a prestigious NIHR doctoral research fellowship.

Krishna completed medicine degree 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 have 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 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 recognition of his expertise, he is frequently invited to speak and serve as faculty at major international scientific meetings, including EuroPCR and CRT.

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.

With comprehensive training in both general and interventional cardiology, Krishna provides an integrated and nuanced perspective during consultations, enabling him to address complex clinical scenarios with clarity, accuracy, and confidence. Patient feedback consistently highlights his warm, empathetic, and reassuring manner, which complements his commitment to delivering the highest quality of personalised care. 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 specialises in the management of coronary artery disease, looking after patients with chest pain, angina, including those with microvascular angina and those who have suffered heart attacks. His procedural expertise is in coronary angiography and complex percutaneous coronary intervention (PCI) with specific interests in high-risk and complex PCI. He works in close collaboration with ceneral 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.

In addition, Krishna possesses clinical expertise in all aspects of cardiology, including treating patients with chest pain, angina (including those with microvascular angina), breathlessness on exertion, palpitations or collapse and managing those who have suffered heart attacks. He has expertise in assessing and treating patients at increased risk of heart disease such as patients with high blood pressure, diabetes or raised cholesterol. He uses all the latest stress testing techniques and if needed, invasive angiography and coronary stenting. His procedural expertise is in coronary angiography and complex percutaneous coronary intervention (PCI) with specific interests in high-risk and complex PCI, using all forms of calcium modification tools.
