Book excerpt: In recent years there has been an increasing interest in quantitative analysis of coronary cineangiograms and already for a longer time of left ventricular cin eangiograms. The needfor quantitationofcoronary arterialdimensions has been stimulated by the introduction ofnew therapeutic procedures in the catheteriza tionlaboratory, suchas the balloon dilatationtechnique (PTCA) and thromboly tic therapy, by the need to study the vasoactive responses of pharmaceutical agents, and also by the desire to study the progressive nature ofcoronary artery disease with the ultimate goal to find ways to bring a halt to the progression of coronary atherosclerosis or even achieve regression of the disease. Parallel with these clinical developments, rapid technical developments in computerarchitect ures and semiconductor memories have made it possible to digitize and store cineframesor selected portions thereof in image processors and to analyze these pictorial data quantitatively at affordable prices. More than 15 years of research have been directed by various groups towards the semi- or fully-automated delineation of the left ventricular boundaries on a frame-to-frame basis. Yet not a single system with fully-automated capability is commercially available. In the mean time many different left ventricular wall motion models have been developed, again with little consensuson which model is to be preferred as no golden standard exists.

Book excerpt: In June 1989, a third conference concentrating on the progress in quantita tive coronary angiography and related techniques was held in Rotterdam, again very successful as the two preceding events in 1985 and 1987. Tech nical as well as clinical aspects of digital and digitized coronarography, morphometry, parametric imaging and functional quantification of the human coronary circulation were presented and discussed by prominent exponents of those groups who have been active in this particular field for many years. This book contains the chapters representing the lectures held by leading experts during the symposium that update the knowledge currently available, including most recent aspects in angioscopy and intravascular ultrasound imaging. It also includes a historical review on the development of angiogra phic techniques from the very early days on to our times given by one of the pioneers in heart catheterization and angiography, Dr. Kurt Amplatz. Those who had the chance to listen to his talk, will surely remember his impressive, humorous lecture as one of the highlights of this meeting.

Available in PDF, EPUB and Kindle. Book excerpt: Whenever the coronary flow is inadequate to provide enough oxygen to meet the energy demands of the tissue, the heart becomes ischemic. Manifestations of myocardial ischemia include depression in contractile activity, changes in metabolic pattern, abnormalities in ultrastructure, and alterations in membrane potential. Ischemic changes during the early phase are reversible but as the period of ischemia is extended, the injury becomes irreversible. The transition from reversible to irreversible ischemic injury is usually associated with some membrane defects. It is worthwhile to consider that the irreversible damage to the ischemic myocardium occurs when the sarcolemmal membrane is altered in suoh a way that it would promote 2 a net gain of ca + in the cardiac cell upon reinstitution of blood flow. Suoh a lesion could result when mechanisms for the entry as well as removal 2 of ca + from the myocardial oell become defective. In this regard, 2 depression of the sarcolemmal ca + pump would favour the oocurrenoe of 2 intracellular ca + overload. Furthermore, inhibition of the Na+-K+ pump would lead to elevation of myoplasmic Na+ which oould then increase the 2 2 intracellular concentration of ca + through the sarcolemmal Na+-ca + exchange mechanism. In faot recent studies have revealed an inhibition of 2 the sarcolemmal Na+-ca + exchange mechanism in the ischemic heart and this 2 change could also contribute towards the occurrence of intracellular ca + 2 overload.

Available in PDF, EPUB and Kindle. Book excerpt: Although some investigators have questioned the importance and even the existence of silent myocardial ischemia, documentation presented at this two day symposium leaves little doubt about its existence and importance. It has been estimated that about 3 million of the estimated 4 million angina sufferers in the United states have frequent episodes of silent myocardial ischemia. Although it is not possible to define how many Americans die due to silent ischemia, it has been suggested that the mortality rate may exceed hundreds of thousands of victims annually. Unfortunately, there still remains a lack of definitive information as to why some ischemic events are painless. Some suggest the concept that the location and size of the myocardium at jeopardy relates to pain, that the pain threshold varies from patient to patient or that there are neurological deficits in the myocardium of some patients with silent ischemia. Abnormalities in myocardial perfusion and function can occur without pain. An interesting observation presented by several investigators has been that when a coronary artery is occluded in man, no ischemic pain is perceived for the first 30 seconds. Only after a 30 second period or so of occlusion does angina occur. An even more confusing observation is that some 30 second periods of occlusion of the same vessel in the same patient results in angina while the next occlusion can be a totally silent event.

Book excerpt: Over the past twenty years, technical advances in coronary arteriography have contributed to our understanding of the pathophysiologic aspects and natural history of coronary artery disease. Probably more than 700. 000 coronary arterio grams are performed annually throughout the world. Usually, these arteriograms are interpreted visually to determine the morphologic extent and severity of coronary artery disease. These subjective determinations, which are hampered . by relatively large intra- and interobserver variations, are used as a basis for critically important therapeutic decisions: Which arteries are to be revascular ized, which lesions are suitable for coronary bypass surgery or for percutaneous coronary angioplasty? To improve on this clinical decision making, on the treat ment and follow-up of such patients, new, objective and reproducible techniques for the assessment of the extent and severity of coronary artery disease, both in terms of anatomy and functional significance of the lesions, must be made widely available. With such new procedures and technologies the efficacy of new thera peutic procedures, the effects of vasodilating and constricting drugs, and the results of long-term studies on the regression and progression of atherosclerotic plaque can be determined in an objective and cost-effective manner.

Critical to our survival, it consists of a tantalizing array of interacting phenomena, from ionic microscopic transport, membrane channels and receptors through cellular metabolism, energy production to fiber mechanics, microcirculation, electrical activation to the global, clinically observed, function, which is measured by pressure, volume, coronary flow, heart rate, shape changes and responds to imposed loads and pharmaceutical challenges. It is a complex interdisciplinary system requiring the joint efforts of the life sciences, the exact sciences, engineering and technology to understand and control the pathologies involved. The Henry Goldberg Workshops were set up to address these challenges. Briefly, our goals are: 1. To foster interdisciplinary interaction between scientists from different areas of cardiology, identify missing links, and catalyze new questions. 2. To relate micro scale cellular phenomena to the global, clinically manifested cardiac function. 3. To relate conceptual modeling and quantitative analysis to experimental and clinical data. 4. To encourage international cooperation so as to disperse medical and technological know how and lead to better understanding of the cardiac system. Today we celebrate the 7th birthday of a dream come true; a dream to bring together the diversified expertise in the various fields of science, engineering and medicine, to relate to the numerous interactive parameters and disciplines involved in the performance of the heart.

Book excerpt: primary goal of all forms of therapy is not just prolonging life, but improving the quality of life, has forced analysis of what constitutes quality of life, a concept whose structure pervades all walks of life and eludes definition. Global well being, happiness, morale, vitality, fullness of social life, and satisfaction must be integrated and assessed for the effects of the disease and the therapy, in the context of specific personality traits, attitudes to life, family situation, and socio-economic and political freedom. A growing inter est in research on this subject has led to a clearer understanding of the components which come to determine quality of a patient's life, and how they can be measured in a reproducible manner so that valid comparisons can be made. Keeping these recommendations of analysing quality of life within the context of patients who have undergone open heart surgery, it seemed appro priate to me to separate the influence of various forms of open heart surgery into five aspects of life which can comprehensively reflect the quality of life outcome of the operation. These five 'components' are (1) Physiological state, which summarises the traditionally reported incidence of operative mortality and morbidity, objectively and subjectively measured physical ca pacity, and the residual symptoms, treatment and long-term survival. (2) Intellectual functioning relates to the psychoneurolgocial deficit in memory, reasoning or judgement because of cerebral microembolism and hypo perfusion during cardiopulmonary bypass.

Book excerpt: This monograph contains 20 selected papers presented at the Symposium on Subcellular Basis of Contractile Failure which was held in Ottawa during May 11-13, 1989 and is designed for the benefit ofthose who were unable to attend this event. It is now increasingly becoming clear that an excessive amount of calcium is intimately involved in the pathogenesis of a wide variety of heart diseases. Accordingly, the investigations concerning the role of calcium chan nels and their regulatory mechanisms in heart function as well as of the intra cellular calcium overload in cardiac dysfunction are presented here. Since sodium is also considered to influence the cardiac contractile force by chang 2 ing the intracellular concentration of calcium through the Na +-Ca+ exchange 2 mechanism in the cell membrane, the role of Na +-Ca+ exchange in heart func tion as well as pathology of contractile failure is discussed. In view of the new ly discovered implications of the oxygen free radicals in cellular injury, papers concerning the role of these radicals in heart disease are included in this book. For the purpose of clarity, different chapters have been organized under three main headings: (I) Role of cations in heart function, (II) Cardiac hypertrophy and cardiomyopathies, and (III) Ischemic heart disease and cardiac failure.

Book excerpt: The Symposium on New Drugs provides a forum for academic investigators, research and development personnel from the pharmaceutical industry and members of the Food and Drug Administration to discuss important clinical research issues. The Ninth Annual symposium on New Drugs addressed the problem of determining the risk versus benefit for use of three important classes of cardiovascular agents: thrombolytic, antiarrhythmic, and hypolipidemic agents. The use of thrombolytic agents has become one of the major advances in clinical intensive cardiologic care in the 1980s. While the lysis of clot(s) obstructing a major coronary artery should reverse or prevent the damage of acute myocardial ischemia and infarction, one must carefully consider the potential risks of such agents in regards to their potential benefits. The time when a thrombolytic agent should be administered to maximize benefit as well as how one defines a dose response relationship using intravenous critical care medicines were discussed as important clinical trial issues. The benefit versus risk data on currently available thrombolytic agents was reviewed and the potential roles for adjunctive agents addressed. Overall strategies regarding post- x thrombolytic care and relationships to sudden cardiac death were also detailed. The panel discussion sections provided a comprehensive view of the current thinking of the various participating groups in this symposium. Sudden cardiac death remains the number one cause of mortality in western industrialized societies.

Book excerpt: The Symposium on New Drugs provides for an annual forum for academic investigators, research and development personnel from the pharmaceutical and related health care industries, and members of the Food and Drug Administration to discuss important clinical research issues. The Tenth Annual Symposium on New Drugs addressed the problem of whether it was still appropriate to approve antihypertensive agents soley on the endpoint of lowering cuff blood pressure. The initial discussions at this symposium related to the approaches and methods to studying antihypertensive agents. Dr. William Frishman provided a detailed list of the new approaches to the treatment of hypertension and pointed out the many new concepts that are currently active in the development of many new antihypertensive agents. Dr. William White detailed the growing importance of ambulatory blood pressure monitoring to define hypertension and to determine the change in blood pressure due to pharmacologically active agents. Dr. Jay Cohn pointed out the flaws in using cuff blood pressure and detailed the potential virtues of using vascular compliance to identify patients requiring treatment for hypertension. Dr. Thomas Pickering also discussed the potential value of evaluating changes in left ventricular hypertrophy a finding which identifies high risk patients who need to be included in clinical trials. Dr. Michael Weber detailed the issues and suggested refinements in the approaches to clinical trial designs for antihypertensive agents and Dr. Raymond Lipicky discussed the definition of dose-duration and the role of non-Mem and Peak/Through measurements in defining an antihypertensive drug effect.

Available in PDF, EPUB and Kindle. Book excerpt: Hypertension is the major cause of left ventricular hypertrophy. While the electrocardiogram is an extremely insensitive measure of anatomic left ven tricular hypertrophy, it provides a time-tested important marker of an adverse cardiovascular outcome. There has been a recent temporal decrease in the incidence of electrocardiographic evidence of L VH even within the hyperten sive population; no doubt this is the result of large antihypertensive treatment experts. Anatomical evidence of left ventricular hypertrophy is best docu mented pre-morbidly using echocardiographic techniques. It therefore ap pears that between 20 and 50 percent of the hypertensive population has left ventricular hypertrophy by echo cardiographic techniques. The prognostic significance of the echocardiographically determined increase in left ventric ular mass is just beginning to be evaluated. Early information suggests that there is an increased rate of cardi~)Vascular morbidity in patients with echo car diographic evidence of increased left ventricular mass. However, this in formation is only preliminary, and as yet only a limited number of events have been reported. Far more supporting information will be required before the full impact of echocardiographically-detected left ventricular hypertrophy can be determined. Nevertheless, it must be stated that the electrocardiogram still has the greatest predictive value of cardiovascular morbid and mortal events when the pattern of left ventricular hypertrophy plus repolarization abnormal ities are present.

Book excerpt: Our understanding of the pathophysiology of acute myocardial infarction has grown enormously in recent years. This has led to an increasingly aggressive approach to management, designed to blunt the extent of infarction by salvaging acutely ischemic myocardium. Alternatives now include throm bolysis, PTCA with and without prior thrombolysis, and emergency bypass surgery, as well as the more aggressive use of a variety of drugs. This book consists of a series of chapters by experienced cardiologists and cardiovascular surgeons that present today's state of the art in managing acute myocardial infarction. It is written with the purpose of presenting practical approaches of value to the clinician related to the more complex problems faced in dealing with patients undergoing myocardial infarction. xi EARLY INTERVENTIONS IN ACUTE MYOCARDIAL INFARCTION 1. MANAGEMENT OF ARRHYTHMIAS IN THE CORONARY CARE UNIT NORA GOLDSCHLAGER, RODERICK WOODS, AND NEAL BENOWITZ With the advent of coronary care units, mortality from cardiac arrhythmias occurring during acute myocardial infarction has been unquestionably and dramatically reduced. In addition, continuous electrocardiographic monitoring has resulted in the recognition of specific arrhythmias related to acute ischemic heart disease and thus to the development of appropriate strategies for their management. This chapter will review certain specific aspects of those bradyarrhythmias and atrial and ventricular tachyarrhythmias that are seen most commonly in acute myocardial infarction. Pharmacologic therapy, including the use of some of the newer antiarrhythmic agents, will be discussed, as will pacemaker ther apy of both bradyarrhythmias and tachyarrhythmias.

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.
