This book was released on 2012-12-06 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coronary flow reserve is an important functional parameter to understand the pathophysiology of coronary circulation. Coronary flow reserve measurement is used to assess epicardial coronary stenoses or to examine the integrity of microvascular circulation. An appreciation of coronary physiology is an integral part of clinical decision-making for cardiologists treating patients with coronary artery disease. The pioneering research efforts of Dr Lance Gould, who explored the relationship between the anatomic severity of a stenosis and its flow resistance (59;60) , have been transferred to clinical practice (94; 194). In the absence of stenosis in epicardial coronary artery, the coronary flow reserve may be decreased when coronary microvascular circulation is compromised by arterial hypertension with or without left ventricular hypertrophy, diabetes mellitus, hypercholesterolemia, or other diseases. Several techniques have been established for measuring coronary flow reserve. However, these techniques are either invasive (intracoronary Doppler flow wire), highly expensive and scarcely available (Positron Emission Tomography - PET) or semi-invasive and causing patient discomfort (transesophageal Doppler echocardiography), thus their clinical use is limited. Because of the clinical importance of coronary flow reserve there is a need for a simple, noninvasive, repeatable and inexpensive tool capable of this functional evaluation. This monograph focuses on the assessment of coronary flow reserve using transthoracic Doppler echocardiography - the technique fulfilling the above-mentioned criteria. Transthoracic Doppler echocardiography has become a popular tool evolving from a research to diagnostic technique applied in everyday practice.

Available in PDF, EPUB and Kindle. Book excerpt: The Heart in Systemic Autoimmune Diseases, Second Edition, provides an overview on our current understanding of major complications relating to the heart and autoimmune diseases. It includes the latest information on the new pathogenetic mechanisms involved, along with clinical manifestations of these important comortbidities. Mortality in autoimmune diseases, in particular, rheumatoid arthritis and SLE, has increased when compared with the general population. This excess mortality is largely due to cardiovascular diseases (CVDs)-particularly those of atherosclerotic origin, such as ischemic heart disease-and is gaining recognition in all branches of medicine, from cardiology, to internal medicine, and from rheumatologists to orthopedics. Presents an impressive body of well ordered information on the topic of cardiovascular diseases and their relationship to autoimmune illness Highlights key references Summarizes the experience of a selected panel of distinguished physician-scientists who are actively involved in the field of cardiovascular disease and systemic autoimmunity

Download or read book What Should We Know About Prevented Diagnostic and Interventional Therapy in Coronary Artery Disease written by Baskot Branislav and published by BoD – Books on Demand. This book was released on 2013-03-20 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mortality from ischemic heart disease has decreased in recent years. The better understanding of risk factors associated with development of coronary artery disease has significantly contributed to this decline. Improvements in medical and interventional therapy have reduced the complications associated with acute myocardial infarction as well as revascularization. After the introduction of imaging modalities, the noninvasive characterization of regional function, perfusion and metabolism allowed for more sophisticated tissue characterization to identify reversible dysfunction with high diagnostic and prognostic accuracy. We now can legitimately claim that computed tomography angiography (CTA) of the coronary arteries is available. In the evaluation of patients with suspected coronary artery disease, many guidelines today consider CTA an alternative to stress testing. However the nuclear technique most frequently used by cardiologists is myocardial perfusion imaging (MPI). The combination of a nuclear camera with CTA allows for the attainment of coronary anatomic, cardiac function and MPI from one piece of equipment. Assessing cardiac viability is now fairly routine with these enhancements to cardiac imaging. Traditional coronary angiography presents a variety of limitations related to image acquisition, content, interpretation, and patient safety. Barriers to such improvements include the paucity of clinical outcomes studies related to new imaging technology, the need for physician and staff member training, and the costs associated with acquiring and effectively using these advances in coronary angiography. This issue is full of important information that every cardiologist needs to now.

Download or read book Contrast Echocardiography written by Harald Becher and published by Springer. This book was released on 2019-07-03 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of the practical aspects of contrast echocardiography. It also covers all the material in the guidelines published by the American Society of Echocardiography (ASE) in 2018 and the recommendations set out by the European Association of Cardiovascular Imaging (EACVI) in 2017. Contrast echocardiography at present is only used in 5-10% of cases, but this is expected to grow rapidly following the recommendations of the ASE and EACVI. The chapters cover the approved indications and provide practical advice on how to administer the contrast agents and how to optimize the recordings as well as how to deal with the pitfalls. The reader will find all the information on how to use contrast agents for assessment of shunts, LV volumes and function as well as myocardial diseases and masses. Detailed protocols are included for stress echocardiography and myocardial perfusion imaging. Other topics covered include the use of contrast agents for coronary sonography and transesophageal echocardiography. Contrast Echocardiography: Compendium for Clinical Practice comprehensively covers all aspects of the clinical use of contrast echocardiography and has been written by two cardiologists who share their experience from their high volume echo laboratories. One of the authors has been a member of both the ASE guidelines and EACVI recommendation writing groups. It is therefore, a critical text for echocardiographers and sonographers who perform echocardiography.

Download or read book Stress Echocardiography written by Eugenio Picano and published by Springer Nature. This book was released on 2023-10-19 with total page 674 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the seventh edition of a long-selling book (first edition 1991) that was translated into Italian, French, Chinese, Portuguese, Spanish, English. In the last ten years, stress echocardiography has exploded in its breadth and variety of applications. From a one-fits-all approach (wall motion by 2D-echo in the patient with known or suspected coronary artery disease), the field has progressed to an omnivorous, next-generation laboratory employing a variety of technologies (from M-Mode to 2D, from pulsed, continuous, color and tissue Doppler to lung ultrasound) on patients covering the entire spectrum of severity (from elite athletes to patients with end-stage heart failure) and ages (from children with congenital heart disease to the elderly with aortic stenosis). This new edition is enriched with over 300 figures, 150 tables and video-clips. In a societal and economic climate of increasing pressure for appropriate, justified and optimized imaging, stress echocardiography offers the great advantages of being radiation-free, relatively low cost, with minimal environmental impact, and with a staggering versatility: we can get more (information) with less (cost and risk). The volume will be a tremendous aid to current best practices for all health operators who intend to use stress echocardiography and ultrasound for diagnosis and guidance of optimal management in their patients.

Download or read book Myocardial Ischemia written by Dennis V. P. Cokkinos and published by Springer Science & Business Media. This book was released on 2006-03-08 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective new treatments of heart disease are based on a refined understanding of cellular function and the heart's response to environmental stresses. Not surprisingly therefore, the field of experimental cardiology has experienced a phase of rapid expo nential growth during the last decade. The acquisition of new knowledge has been so fast that textbooks of cardiology or textbooks of cardiovascular physiology are often hard-pressed to keep up with the most important conceptual advances. Witness the explosive increase in knowledge about signaling pathways of cardiac growth, transcrip tional regulation of cardiac metabolism, hormonal signaling, and the complex responses of the heart to ischemia, reperfusion, or ischemic preconditioning. This book is meant to bridge the gap between original literature and textbook reviews. It brings together inves tigators of various backgrounds who share their expertise in the biology of myocardial ischemia. Each chapter is a self-contained mini-review, but it will soon become apparent to the reader that there is also a common thread: Molecular and cellular cardiology has never been more exciting than now, but ever more exciting times are yet to come. The Editors ACKNOWLEDGEMENTS - Publication of this book was generously supported by Sanofi-Aventis Hellas. - Eikon creative team provided the technical assistance in preparing the manuscripts. - We thank Dr. Bernard Swynghedauw for all his scientific support.

Download or read book Handbook of Contrast Echocardiography written by Harald Becher and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the technology required for the successful application of contrast echo cardiography has evolved rapidly over the past few years, the technique has not yet gained widespread clinical acceptance. One important reason for the lack of clinical acceptance is the relative complexity of the technique, particularly in respect to myocardial perfusion imaging. The interaction between micro bubbles and ultrasound is an entire field by itsel£ as is the coronary microvasculature. It is in this regard that practicing echocardiographers, cardiologists in training, radiologists, so no graphers, and students will find 'A Handbook of Contrast Echocardiography' particularly useful. Written by two leaders in the field who have presented illustrative cases not only from their own laboratories but also from others around the world, this volume is a lucid, concise, and practical guide for the day-to-day use of contrast echocardiography. Dr Peter Burns has been involved in almost all the technical advances in the imaging methods that have made it possible to detect opacification of the left ventricular cavity and myocardium from a venous injection of microbubbles. He has been responsible to a large degree for advancing our understanding of the interaction between micro bubbles and ultrasound, which he describes in clear and easy to understand terms in this book. Dr Harald Becher has been active in the clincal application of contrast echocardiography for several years and has gained considerable experience with many imaging techniques and microbubbles, which he describes in this volume in some detail.

This book gathers the latest research in cardiovascular disease with a focus on such topics as cardiac thrombus quantification in clinical practice; aspartate protease cathepsin D in liver and heart injury, pathophysiology and therapy; hypertension, arterial stiffness and cardiovascular outcomes; fractional flow reserve is an essential measure for the management of patients with stable coronary artery disease; arterial stiffness and vascular calcifications in chronic kidney disease patients; the clinical application of coronary flow velocity reserve by transthoracic Doppler echocardiography; management of right heart failure; short QT syndrome; new horizons in preventing graft arterial disease; and associations between cathepsin B and inflammation markers in elderly males and females.

Download or read book Coronary Microvascular Dysfunction written by Filippo Crea and published by Springer Science & Business Media. This book was released on 2013-08-15 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past two decades a number of studies have shown that abnormalities in the function and structure of coronary microcirculation can be detected in several cardiovascular diseases. On the basis of the clinical setting in which it occurs, coronary microvascular dysfunction (CMD) can be classified into four types: CMD in the absence of any other cardiac disease; CMD in myocardial diseases; CMD in obstructive epicardial coronary artery disease; and iatrogenic CMD. In some instances CMD represents an epiphenomenon, whereas in others it represents an important marker of risk or may contribute to the pathogenesis of myocardial ischemia, thus becoming a possible therapeutic target. This book provides an update on coronary physiology and a systematic assessment of microvascular abnormalities in cardiovascular diseases, in the hope that it will assist clinicians in prevention, detection and management of CMD in their everyday activity.
