final EBM lipid disorders cover for press.qxd 11/05/2010 15:18 Page 1 Practicing evidence-based medicine necessarily depends on the E Evidence-based v id clinician having access to the best evidence available, but in a fast- e n moving field, keeping up to date with the latest developments is a c e - challenging prospect. In this new volume, leading experts focus on the b a Management of s most important clinical issues associated with the management of lipid e d disorders, evaluating and interpreting the evidence available to M a provide the reader with a reliable summary of our current knowledge. n a g e LIPID DISORDERS m Topics covered include therapeutic strategies for managing e n hereditary lipid disorders, including familial hypercholesterolemia, both t o f in adults and children, and familial combined hypercholesterolemia. L ip The authors also evaluate the evidence for a link between inflammatory id D disease and cardiovascular risk, the metabolic syndrome and the is o interconnections between dyslipidemias and diabetes. They also look r d e at therapeutic challenges such as the management of patients who are r s statin intolerant, and the control of lipid levels in those suffering renal insufficiency. Tables highlight important data, evidence from trial results and expert reports, and each section concludes with a series of key points that present a summary of evidence-based recommendations for best practice, graded according to the quality of that evidence. This book provides the busy clinician with a unique analysis of the data supporting current therapies and will help the reader formulate effective strategies for treating their own patients.

Tamsma Index 299 iv prelims_prelims.qxd 11-05-2013 20:54 Page v Foreword Worldwide, cardiovascular diseases are among the leading causes of death, and atherosclerosis is by far their most common cause. A century has passed since the term ‘atherosclerosis’ was first introduced by F. Marchand in 1904, who suggested that atherosclerosis was responsible for almost all obstructive processes in the arteries. A few years later, the relationship between cholesterol and atherosclerotic plaques was discovered, first by A. Windaus, who detected cholesterol in human atheromatous lesions in 1910, and shortly thereafter, in 1914, by N. Anichkov and S. Chalatow, who discovered the significance and role of cholesterol in atherosclerosis pathogenesis based on their landmark experiments in rabbits. These discoveries heralded a spectacular research effort in the relation between cholesterol and atherosclerosis. A century of studies on atherosclerosis later, we not only acknowledge the crucial role of LDL-cholesterol in the development of cardiovascular diseases, but we also recognize other players in the field. These risk factors include, but are not restricted to, low HDL-cholesterol levels, high triglyceride levels and the size of the lipoproteins, as well as lifestyle and diseases that impair a healthy lipoprotein balance, such as diabetes, metabolic syndrome, inflammatory diseases, renal insufficiency, and – although not related to lipids – hypertension. Along with these discoveries, several therapeutic strategies have been developed during the last decades. Some of them have been proven to improve lipid levels and to reduce cardiovascular risk, whereas others are still in the investigational phase. The authors were asked to look systematically at the literature and to evaluate and interpret the available evidence on the selected topics in order to provide the reader with a reliable summary of the current knowledge on the management of lipid disorders. Each chapter concludes with a series of key points that present a summary of evidence-based recommendations for best practice, graded according to the quality of the evidence. For certain topics, however, there are no data from well-designed randomized controlled trials (RCTs), just because it is too early or RCTs are not feasible. As outlined in the first chapter by Dr. Steinberg, RCTs provide by far the most valuable evidence guiding decisions regarding medical intervention, but other relevant evidence must be considered as well. In such cases we have to rely on case reports, descriptive studies or opinions and/or clinical experience of respected authorities. We are grateful to all the authors for their phenomenal task in putting all the available evidence-based information together. We hope that readers will enjoy all the chapters as much as we did.
