DDDDDDDDDDDD Effective management logically follows accurate diagnosis. Such logic often is difficult to apply in practice. Absolute diagnostic accuracy may not be possible, particularly in the field of primary care, when management has to be on analysis of symptoms and on knowledge of the individual patient and family. This series follows that on Problems in Practice which was concerned more with diagnosis in the widest sense and this series deals more definitively with general care and specific treatment of symptoms and diseases. Good management must include knowledge of the nature, course and outcome of the conditions, as well as prominent clinical features and assess­ ment and investigations, but the emphasis is on what to do best for the patient. Family medical practitioners have particular difficulties and advantages in their work. Because they often work in professional isolation in the com­ munity and deal with relatively small numbers of near-normal patients their experience with the more serious and more rare conditions is restricted. They find it difficult to remain up-to-date with medical advances and even more difficult to decide on the suitability and application of new and rela­ tively untried methods compared with those that are'old'and well proven. Their advantages are that because of long-term continuous care for their patients they have come to know them and their families well and are able to become familiar with the more common and less serious diseases of their communities.

Cardiology embraces a number of different conditions and disease processes. Cardiovascular disease is now responsible for most of the deaths of adults, especially premature deaths, in the developed world. The development of effective preventive measures, new drugs and surgical techniques makes it increasingly important to recognise those at risk, to diagnose accurately those suffering from disease and to prescribe, monitor and refer appropriately. This book is intended to focus attention on the opportunities which family'practice provides for this and to look at the need for a change in emphasis in approaching the problems. The book is in five parts. Part 1 is a reminder of some of the basic principles, which are essential if sensible cardiology is to be practised. Part 2 is about cardiac drugs, their use, effectiveness and risks. Part 3 looks at the diagnostic process; it comprises the history, examination, investigation and referral of patients, who might have cardiac disease and also the drugs which are most likely to be used. Part 4 is devoted to specific conditions. In Part 5, we look at the need for prevention and consider how it may be tackled in general practice. This is not a comprehensive textbook of cardiology. It is not intended for students. It is hoped that it may be useful to experienced doctors, struggling to provide a sound, sensible service in an environment of ever expanding technology.
