Intracoronary ultrasound is a rapidly evolving imaging modality and the increasing number of published studies indicates that the technique is safe and provides incremental and more detailed diagnostic information than coronary angiography. The technique has the potential to study the pathobiology of atherosclerosis, to clarify the significance of angiographically equivocal lesions and has helped us to understand the mechanisms, effects and complications of catheter-based revascularization procedures. Combinations of imaging and therapeutic devices are being developed for both guidance and assessment of the revascularization procedure. Three-dimensional reconstruction of coronary segments is now possible in real time and provides the opertor with more detailed information on coronary pathology. In this monograph, leading experts in the field present the state of the art of all these new developments.
Potbelly syndrome (PBS) is a metabolic disorder that affects about one-third of the adults in industrialized countries. Its most important symptoms are abdominal obesity, high blood pressure, and type 2 diabetes. Contrary to popular belief, these conditions are caused by chronic infections, not by bad habits. PBS is initiated by a small, long-term excess of the stress hormone cortisol. The extra cortisol stimulates our appetite and slows down our metabolism. It makes fat accumulate in places where it isn't wanted or needed. Most of the fat settles around our waists, but some of it settles in our liver and muscles. Liver and muscle cells aren't supposed to store fat, and the fat prevents them...

A history illustrating the complexity of medical decision making and risk. Still the leading cause of death worldwide, heart disease challenges researchers, clinicians, and patients alike. Each day, thousands of patients and their doctors make decisions about coronary angioplasty and bypass surgery. In Broken Hearts David S. Jones sheds light on the nature and quality of those decisions. He describes the debates over what causes heart attacks and the efforts to understand such unforeseen complications of cardiac surgery as depression, mental fog, and stroke. Why do doctors and patients overestimate the effectiveness and underestimate the dangers of medical interventions, especially when doing so may lead to the overuse of medical therapies? To answer this question, Jones explores the history of cardiology and cardiac surgery in the United States and probes the ambiguities and inconsistencies in medical decision making. Based on extensive reviews of medical literature and archives, this historical perspective on medical decision making and risk highlights personal, professional, and community outcomes.
