Download or read book Coronary Circulation and Myocardial Ischemia written by Michael R. Pinsky and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: The coronary circulation is central to sustaining myocardial viability. Unlike the cir culations of most other organs, if the coronary circulation becomes insufficient to sustain myocardial contractile function, overall quality of life rapidly declines and life can abruptly end. In partnership with the cerebral circulation, the coronary circula tion plays a central role in sustaining life. However, unlike the cerebral circulation, whose function is self-sufficient to define life, the coronary circulation determines global blood flow and thus the initial state for the remainder of the body. This unique condition, together with the reality that coronary artery disease primarily affects peo ple in their productive years of life, has allowed physicians and scientists who study the heart to enjoy a privileged position in the field of medical research and clinical practice. Thus, it comes as little surprise that many new and exciting research developments involving the coronary circulation have recently come to the forefront of medical thinking. This reality, coupled with the large number of clinical trials of agents specif ically designed to sustain or improve coronary flow in many disease states, makes the timing of this monograph relevant. The book features papers presented at a recent international symposium, the fourth in a series of meetings on Applied Physiology of the Peripheral Circulation. The papers selected by the editors review the most impor tant advances in the fields of cardiology and the coronary circulation.
Download or read book Coronary Circulation written by Fumihiko Kajiya and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coronary heart disease is one of the major health problems in indus trialized nations because of its high incidence and severity. Recent innovations in medical and surgical treatment of coronary heart dis ease have increased the importance of accurate diagnostic methods for determining the severity of coronary disease, identifying potential treatment alternatives, and evaluating the results of treatment. Great advances have also been made in basic research on coronary circula tion and its interaction with myocardial contraction and relaxation and neural and humoral control. With respect to these developments, the papers included in the present monograph deal with important topics concerned with the basic mechanism of coronary circulation as well as ones of clinical relevance. It is directed toward physicians (cardiologists, cardiac surgeons, cardiac radiologists, anestheologists, and others) and basic scientists (e.g., physiologists, bioengineers). We would like to em phasize the importance of a multidisciplinary approach in which basic scientists and clinicians work closely together. This volume consists of nine chapters. Chapter 1 contains macro scopic and microscopic descriptions of coronary vascular anatomy, which is closely related to the functions of coronary circulation. In Chap. 2 two methods in current use to evaluate phasic coronary blood velocity waveforms are presented, i.e., the laser Doppler and ultrasound Doppler methods. Chapter 3 describes the mechanical properties of coronary circulation, a knowledge of which is indispens able for an understanding of coronary arterial and venous blood flow velocity waveforms in relation to cardiac contraction and relaxation.

This book was released on 2012-12-06 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: MOTOOMI NAKAMURA As we approach the 21st century, ischemic heart disease is the major cause of death in most of the developed nations of the world. Since the 1970s, much effort and expense have led to designs of coronary thrombolytic therapy, percutaneous coronary angioplasty (PTCA), coronary artery bypass grafting, heart transplantation, automatic defibrillators, as well as to the formation of beta blockers and com pounds which block the calcium channel. Socio-educational programs directed at exercise, diet, instruction in the risk factors of smoking, hyperlipidemia and hypertension have contributed to the decrease in the rate of morbidity and mortality of patients with ischemic heart disease. However, the first clinical event of ischemic heart disease, the so-called "heart attack" and sudden cardiac death continues to present problems, as the mechanisms involved in these events are poorly understood. It has long been thought that ischemic heart disease is the sequence of an organic fixed atherosclerotic obstruction of the epicardial coronary arteries and the role of coronary vasomotion has been given much less attention. Recent clinical and laboratory animal studies revealed that increased tonus and spasm of the large epicardial coronary arteries are the cause of various stages of ischemic heart disease. The role of coronary vasospasm in the development of un stable angina, sudden cardiac death and acute myocardial infarction remains open to debate. Pharmacophysiological studies showed that the epicardial large coronary artery contributes only 5% to regulation of normal coronary flow.

Available in PDF, EPUB and Kindle. Book excerpt: "Diseases associated with impairment of the coronary circulation are very common. Hence, the treatment of such diseases is a matter of considerable importance. It is now considered one of the main problems of clinical medicine. The basis for solving the problem is to enlarge our knowledge of the mechanisms of action of the drugs used to treat coronary insufficiency and to find new effective agents. Owing to the complexity of physiological regulation of the coronary circulation, there are many difficulties of a procedural order in studying it experimentally. This was one of the reasons why ideas on the action of many pharmacological agents were derived until recently from the results of experiments involving the isolated heart. When applied to the intact organism, these ideas proved to be inexact and, at times, wrong. Some ideas on the effects of certain drugs were based on experiments involving the intact organism, but the data proved to be inexact due to the inadequacy of the method selected by the authors to determine the mechanism of action of a given substance. Another reason for misconceptions of the effects of some drugs stemmed from insufficient knowledge and contradictory opinions expressed by various investigators on many aspects of the coronary circulation. Now, however, advances in experimental techniques have produced new facts bearing on the physiological regulation of the cardiac blood supply. This has given rise to the need to reexamine some matters concerned with the influence of pharmacological agents on the coronary circulation, relying on modern ideas concerning its physiological regulation and using adequate experimental techniques. Most drugs have complex mechanisms of action owing to the intimate relationship between the processes regulating the cardiac blood supply. Elucidation of these mechanisms requires the use of various techniques, each of which must be suited to the particular aspect under study. This approach will result in a reappraisal of the action of several pharmacological agents on the coronary circulation. Moreover, we believe that the data in this book will be helpful in making more efficient use of these agents in the treatment of various forms of coronary insufficiency."--Introduction

This book was released on 2012-12-06 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coronary circulation research is advancing at a rapid rate. Not only are inno vative techniques for studying myocardial perfusion being developed, new mechanisms related to coronary blood flow control and mechanics are also being discovered. The progress in this field justifies an update in the form of this new monograph. The book is divided into the following sections: "Measurement of Coronary Blood Flow and Assessment of Myocardial Per fusion" discusses advances in perfusion measurements in humans as well as nonradioactive microsphere methods. . "Coronary Flow Dynamics" elucidates the effect of heart contraction on coronary flow, perfusion, and reserve distribution as well as systolic-diastolic interaction. Models-a frequent topic of debate-are used to quantify hypotheses. "Models of Coronary Circulation" attempts to elucidate the concept of tissue pressure. "Regulatory Mechanisms of Coronary circulation and its Clinical Relevance": N u.merous mechanisms affecting coronary flow have been defined and studied at the level of isolated vessels and whole organs. The chapters in this section provide an in-depth analysis of a selection of these mechanisms and their inter actions. "Pathophysiology of Coronary Circulation in Ischemic Heart Disease" considers important aspects of factors which restrict perfusion of the myocardium in ischemic heart disease. An understanding these factors is of crucial importance in the management of patients. "Small Vessel Disorder in Coronary Circulation" describes circulatory flow and how it can be influenced by drugs.

Download or read book Chronic Total Occlusions written by Ron Waksman and published by John Wiley & Sons. This book was released on 2011-08-31 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chronic total occlusions (CTO) are common, and found in approximately one third of patients with significant coronary artery disease who undergo angiography. Over the past 20 years, CTO lesions have represented the most difficult anatomy for treatment — with lower success rates and higher complication rates. Chronic Total Occlusions provides interventionalists insight into the world of CTOs with introductory chapters that describe the pathology and indications of CTOs along with a review of clinical trials. Imaging modalities including CT angiography, magnetic navigation wire, and IVUS guided recanalization of CTO are also introduced, together with information on new wires technology and devices for CTOs. With numerous illustrations of these devices, technologies, and strategies to improve the CTO success rate, this clinical guide, headed up by Ron Waksman, will prove to be the ideal companion for interventional cardiologists and cardiac surgeons who are required to perform angioplasty and coronary stenting.
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.

Available in PDF, EPUB and Kindle. Book excerpt: by JULIEN IE HOFFMAN One of the earliest coronary physiologists was Scaramucci who, in 1695, postu lated that during systole the contracting myocardium inhibited coronary blood flow. Since then, the many contributions that have been made to our knowledge of the coronary circulation can be arbitrarily divided into three phases based on advances in technical methods. The early phase of research into the coronary circulation, done with great difficulty with crude methods, may be regarded as ending in the 1940s, and it included major discoveries made by such well known investigators as Georg von Anrep, Ernest Starling, Carl Wiggers, and Louis Katz, who formulated much of our basic understanding of the field. After 1940, the field of coronary physiology entered a new phase when instruments for high fidelity registration of coronary flow and pressure became available. This era was domi nated by Donald Gregg who combined careful attention to the function of these instruments (some of which he helped to develop) with an extraordinary ability to discern mechanisms from apparently minor changes in coronary flow and pressure patterns. His book 'The Coronary Circulation in Health and Disease' set a new standard in the field. After 1960, techniques for measuring regional myocardial blood flow became available, and enabled a large group of eminent investigators to make major advances in understanding the physiology and pathophysiology of myocardial blood flow.
Download or read book Coronary Circulation written by Jos Spaan and published by Springer. This book was released on 1987-10-31 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: In the intervening 10 years tremendous advances in the field of cardiac computed tomography have occurred. 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 (CAD), many guidelines today consider CTA an alternative to stress testing. The use of CTA in primary prevention patients is more controversial in considering diagnostic test interpretation in populations with a low prevalence to disease. 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. PET/SPECT cameras can now assess perfusion, function, and metabolism. Assessing cardiac viability is now fairly routine with these enhancements to cardiac imaging. This issue is full of important information that every cardiologist needs to now.
