Participation in athletics at both the recreational and competitive levels has grown enormously over the last decade, and now involves a substantial segment of the population of many countries, particularly those in Europe and North America. This change in the life-style of many individuals has been accompanied by the desire and necessity on the part of physicians to define the consequences of chronic athletic training and competition to the participant. Coincident with the of public interest in sporting competition has been the evolution and growth development of new non-invasive technologies in cardiology (such as M-mode and two-dimensional echocardiography and radionuclide angiography) which have permitted investigators to study directly and more precisely the morphology and function of the heart and cardiovascular system. Hence, over the past several years our knowledge has been greatly enhanced with regard to the features of the normal 'athlete heart' and the relationship of athletic conditioning to preexistent cardiovascular disease, as well as the causes of sudden death in athletes. The present treatise on 'Sports cardiology: Exercise in Health and Cardio vascular Disease' is an impressive reference document which is also timely. It fulfills an important role in summarizing most of the available data that has been accumulated over the last 10 years in a large number of athletes participating in a variety of different sports.

Hypertension is a major world-wide health problem. With high blood pressure there is a greater risk of stroke, heart attack, heart failure, kidney disease and renal failure. Far too few people realize what the risks are and what can be done to prevent these risks even in the countries where pro grams in hypertension research are active and the full significance of hyper tension is best understood. Some studies of the known hypertensive popu lation indicate that one-half or less are receiving adequate treatment, and, of those on therapy, only half have their high blood pressure satisfactorily controlled. These realizations emphasize the need to inform all segments of society throughout the world on the importance of detection and control of high blood pressure. The great incidence of hypertension makes it of para mount importance that all practicing physicians have available the latest information on diagnosis and treatment of hypertensive cardiovascular dis ease. This treatise on hypertension arrives at a time when there is an increasing recognition the world over of the importance of detecting and treating high blood pressure. The book has been edited by Dr. A. Amery and his asso ciates in the University of Leuven. Professor Amery is one of the leaders in the field of hypertension and serves on the Council of the International Society of Hypertension."
