This knowledge includes core science and clinical skills, from understanding biochemical pathways to communicating with patients. Modern medical school curricula integrate this teaching, thereby emphasising how learning in one area can support and reinforce another. At the same time students must acquire sound clinical reasoning skills, working with complex information to understand each individual’s unique medical problems. The Eureka series is designed to cover all aspects of today’s medical curricula and reinforce this integrated approach. Each book can be used from first year through to qualification. Core biomedical principles are introduced but given relevant clinical context: the authors have always asked themselves, ‘why does the aspiring clinician need to know this?’ Each clinical title in the series is grounded in the relevant core science, which is introduced at the start of each book. Each core science title integrates and emphasises clinical relevance throughout. Medical and surgical approaches are included to provide a complete and integrated view of the patient management options available to the clinician. Clinical insights highlight key facts and principles drawn from medical practice. Cases featuring unique graphic narratives are presented with clear explanations that show how experienced clinicians think, enabling students to develop their own clinical reasoning and decision making. Clinical SBAs help with exam revision while Starter questions are a unique learning tool designed to stimulate interest in the subject. Having biomedical principles and clinical applications together in one book will make their connections more explicit and easier to remember. Alongside repeated exposure to patients and practice of clinical and communication skills, we hope Eureka will equip medical students for a lifetime of successful clinical practice. Janine Henderson, David Oliveira, Stephen Parker vi About the Series Editors Janine Henderson is the MB BS undergraduate Programme Director at Hull York Medical School (HYMS). After medical school at the University of Oxford and clinical training in psychiatry, she combined her work as a consultant with postgraduate teaching roles, moving to the new Hull York Medical School in 2004. She has a particular interest in modern educational methods, curriculum design and clinical reasoning. David Oliveira is Professor of Renal Medicine at St George’s, University of London (SGUL), where he served as the MBBS Course Director between 2007 and 2013. Having trained at Cambridge University and the Westminster Hospital he obtained a PhD in cellular immunology and worked as a renal physician before being appointed as Foundation Chair of Renal Medicine at SGUL. Stephen Parker is a Consultant Breast and General Paediatric Surgeon at St Mary’s Hospital, Isle of Wight. He trained at St George’s, University of London, and after service in the Royal Navy was appointed as Consultant Surgeon at University Hospital Coventry. He has a particular interest in e-learning and the use of multimedia platforms in medical education. About the Authors Paul Morris is a Specialist Registrar in Cardiology. He enjoys teaching medical students and junior doctors and has extensive experience of writing exam questions and developing clinical assessment tools. He is also a Clinical Research Fellow in Cardiovascular Science at the University of Sheffield, working on the computational modelling of cardiovascular physiology. David Warriner is a Specialist Registrar in Cardiology in South Yorkshire. He teaches undergraduates and postgraduates in lectures, tutorials and on the wards. He has developed novel interactive tools for understanding the pathophysiology of cardiovascular disease and still enjoys learning about cardiology as much as he does teaching it. Allison Morton is a cardiologist in Bunbury, Western Australia. Previously she was a Consultant Cardiologist at Sheffield Teaching Hospitals, where she ran the clinical cardiology training for medical students, giving lectures and examining students on the MBChB course. She teaches candidates for the clinical PACES exam and is proud of her 100% pass rate! vii Preface The World Health Organization ranks cardiovascular disease as the leading cause of death, accounting for three in every ten deaths worldwide and frequently presenting as an emergency requiring immediate management. Irrespective of speciality, all doctors need to be confident in dealing with cardiovascular disease. To achieve this, it is not enough to learn clinical medicine alone. One must also understand the scientific principles and mechanisms,
