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."

Over several years working in a district general hospital as a physician with a cardiological interest, the common problems in this field are clearer. This knowledge has come through normal out-patient clinic referrals, care of in-patients, and by working in a domiciliary consultative capacity. The problems that concern family physicians nowadays are somewhat different from the problems of two or three decades ago. The accent now is very much on the implications of hypertensive and ischaemic heart disease. Rheumatic fever is rarely seen, though its sequelae may still be discovered. Hence the approach of this book is to the common problems of today in family practice, and the book is not intended to be a reference text book of cardiology. It does not include references because it has been written from personal experience gained from the treatment and management of patients with common cardiac problems. It is hoped that it will be of value primarily to family physicians because it has been written in an attempt to fill a need as measured by the problems that are referred to specialists in the cardiological field. It may prove of value to those medical students and nurses who wish to consider medical problems in a practical way, that is from the ways that cardiac problems present in practice.
