The importance of left ventricular hypertrophy (LVH) in cardiovascular disease has gained wide recognition. LVH is a highly important risk factor associated with major cardiovascular events, including symptomatic heart failure, particularly in patients with systemic hypertension. In recent years much has been learned about the genetics, molecular background, prevalence, incidence and prognosis of LVH. A variety of noninvasive methods has emerged for detecting LVH and the assessment of reversal of hypertrophy, yet a lot of controversy remains about the connotations and clinical implications of LVH. For instance, in the athlete's heart LVH may constitute a physiological adaptation to pressure overload, which normalizes following discontinuation of strenuous physical activity. On the other hand, in particular in patients with hypertension, LVH denotes a serious prognosis in the course of hypertension. In these patients LVH should be regarded as a grave prognostic sign rather than an innocent compensatory phenomenon. The distinction between physiologic and pathophysiologic LVH is the basis for this book. Left Ventricular Hypertrophy - Physiology versus Pathology is a bibliographical reflection of a Boerhaave Symposium held on April 9, 1999, in Leiden, The Netherlands. At this symposium the major issues in dealing with LVH were discussed, including etiology, genetics, detection, and therapy. In particular, the book includes novel detection methods for LVH such as magnetic resonance imaging and spectroscopy. Furthermore, much attention was paid to the molecular and genetic approach of LVH. This book will assist clinical cardiologists, fellows in cardiology, general internists, radiologists, cardiothoracic surgeons, biochemists, physiologists, pharmacologists, and basic research fellows in understanding the most recent insights in the background of physiologic versus pathologic LVH.

Few diagnostic methods in Cardiology have heralded such revolutionary developments as the introduction of coronary arteriography. When, in the early 1960's, Dr. F. Mason Sones demonstrated that visualization of the coronary anatomy in living humans was not only feasible but sufficiently safe and reliable to be used as a clinical tool in the evaluation of patients with known or suspected ischemic heart disease, the thus far somewhat neglected area of coronary circulation became the focus of interest. Naturally, for a considerable period of time a great deal of emphasis was placed upon coronary anatomy. Simple relations between narrowing lesions, impediment to flow, and prognosis were assumed to exist. Spectacular results of surgical coronary revascularization seemed to confirm this concept. Gradually it has become evident that the pathophysiology of coronary artery disease is considerably more complex. Diagnostic methods were introduced to assess and quantify exercise-induced myocardial ischemia. At first, these tests were used mainly to achieve a more discriminative selection of candidates for coronary arteriography and the coronary arteriogram remained the gold standard. Currently, these techniques have evolved to the point where they provide valuable functional and metabolic information. They have become powerful independent tools in clinical investigations and evaluation of individual patients.

A unique overview of all major angiographic lipid intervention trials, presented by their principal investigators. Basic mechanisms and methodological aspects, including biochemical as well as angiographic aspects, are discussed by experts in these fields. A careful comparison of all available data permits an analysis to be made of what may currently be considered proved, which aspects merit further investigation, and which hypotheses should be rejected. Audience: Clinicians involved in the practice of lipid lowering and investigators involved in lipid-lowering clinical trials. Scientists involved in other areas of lipid research and investigators conducting coronary angiographic trials designed to study the influence of different interventions will find a wealth of information and practical guidelines in this book.
