Professional statement

With over 20 years of medical experience, Dr Teresa Castiello is a a multi award winner and leading cardiologist based in London, specialising in acquired and inherited cardiomyopathy, heart failure, preventive cardiology, family screening, syncope, hypertension, and cardiac magnetic resonance. Her extensive career has highlighted the critical importance of prevention and early diagnosis, balancing profound clinical experience with cutting-edge research.


Dr Castiello is a passionate and multi-faceted clinician whose dedication to excellence and innovation in cardiovascular care earned her the prestigious title of Cardiologist of the Year 2024 – UK, alongside global awards for Advancing Health with Technology and Global Impact in Healthcare, Helathcare Leader and Healthcare Woman Entrepreneur of the year. 


She adopts a deeply holistic approach, prioritizing the person before the pathology by taking into account her patients’ physical and mental well-being and their unique backgrounds. As an NHS consultant cardiologist and the founder and director of MIAL Healthcare, Dr Castiello is dedicated to advancing cardiology through clinical excellence, innovation, research and global collaboration.


MIAL is a healthcare social business venture designed to deliver specialized, personalized, and multidisciplinary care pathways both in-person and remotely. By integrating digital health innovation into clinical practice, MIAL aims to break down geographic and structural barriers, ensuring that high-quality, empathetic, and holistic care is accessible to all. Her clinical expertise is further bolstered by her international certification as a Level 3 ESC/SCMR practitioner in Cardiac Magnetic Resonance (CMR) imaging, which is a cornerstone of her work in sudden cardiac death prevention and cardiomyopathy management.


In the academic and research arena, Dr Castiello is a prominent figure driving innovation in heart failure and digital diagnostics. She currently serves as the chief investigator (CI) of the HF track trial, a pioneering study on the use of Artificial Intelligence in heart failure, and is the CI of an interantioank multicentric clinical trial on pericarditis.


Beyond her roles as a chief investigator, she is a principal investigator (PI) on multiple other clinical trials and has contributed extensively to international medical literature as an author and co-author of ESC Clinical Consensus papers. Her work as a digital health expert includes a former membership in the Patient Care and Digital Health Committee of the European Heart Failure Association (HFA of ESC), where she remains actively engaged in numerous projects for both clinical and research purposes.


Her leadership extends to the highest levels of international cardiology societies. Dr. Castiello is an Executive Board Member of the European Nucleus of Cardiomyopathy of the European Society of Cardiology (ESC), a representative on the Genomic Council of the ESC, and a member of the Inflammatory Cardiomyopathy Committee of the European Heart Failure Association. Notably, she is the immediate past President of the Royal Society of Medicine (Cardiology Section), distinguishing herself as the first woman to ever hold that role. As a Medical Science Communicator, she excels at making complex medical topics accessible to the public through TV, radio and social media engagement and educational outreach, while serving as a role model and advocate for diversity, inclusion, and the advancement of women in medicine.


Dr Castiello’s commitment to healthcare as a universal right is evidenced by her significant humanitarian work in developing countries. Between 2009 and 2011, she dedicated her professional and personal time to three major missions in Africa and East Jerusalem. Her longest mission was in Sudan, where she worked at the Salam Center for Cardiac Surgery on the outskirts of Khartoum. In this role, she screened patients with suspected or documented cardiac diseases to select those suitable for life-saving heart surgery. In Kenya, she evaluated the suitability for creating a dedicated cardiac surgery unit and provided essential training to local medical staff. In East Jerusalem, she proudly collaborated with a children’s NGO, ensuring that specialised cardiac care reached vulnerable paediatric populations.


Dr Castiello graduated in medicine and surgery with honours from La Sapienza University, Rome, in 2001, where she completed her medical and initial cardiology training (MD). In 2009, she achieved her specialisation in cardiology at the University Campus Bio-Medico, Rome. These academic foundations, combined with nearly 25 years of international experience spanning Italy, the UK, and several developing nations, have shaped her into a clinician who thrives on innovation and the belief that high-quality, compassionate healthcare should be available to everyone, regardless of their circumstances.

  • I had my first appointment with Dr Teresa Cadiello and I couldn't be more grateful for the care I received. From the moment I walked in Dr Teresa made me feel completely at ease. She was incredibly kind, empathetic and took the time to truly listen to all my concerns without making me feel rushed. She explained everything clearly and thoughtfully, with her recommendations. I am very grateful for her care and would highly recommend her to anyone looking for a knowledgeable caring cardiologist.

  • I am incredibly grateful to have found Dr. Castiello. Unlike previous cardiologists who overlooked my concerns and relied on one-size-fits-all guidelines that never improved my condition, she was extremely thorough and genuinely cared about my case. Dr. Castiello demonstrated a level of competence far beyond any other specialist I have met; she treats the patient holistically rather than just focusing on the heart in isolation. I cannot recommend her highly enough.

  • I selected Dr Castiello having been impressed by reading her work and clinical achievements. We had an hour long first consultation the next day and I can honestly say that her knowledge/expertise resulted in a relaxing, calming experience. She is so down-to-earth and listens to every concern you have, which she treats with the utmost importance. She clearly explained everything and eased my anxiety, even offered out-of-hour help. She really is a "top doctor" and I can thoroughly recommend her.

Her deep knowledge and extensive training are evident in every consultation. She is thorough, attentive, and genuinely patient-focused, always taking time to listen carefully.

  • I went to Dr. Castiello on the recommendation of a colleague from work and I definitely recommend her to others. During the analysis of my heart problem, the doctor carefully took into account my pre-existing autoimmune disease. The continuation of my treatment was introduced not only based on textbook guidelines, but also on my individual case and tailored to my specific needs. Dr. Castiello is very dedicated and devotes as much time to the patient as necessary. She is always easy to reach.

  • There are a few really great doctors and consultants. Dr Castiello is not great, she is simply 'beyond great', quite extraordinary. Bang up to date. Deep listener. Truly empathic. Takes a whole person view. Explains brilliantly. It's rare you recommend someone so so so highly.
