Catheter ablation is widely accepted as an effective and safe form of therapy for cardiac arrhythmia. In many instances this curative procedure is considered as the first line of therapy if not the ultimate treatment of choice. With the use of radiofrequency (RF) modality; which has revolutionized the technology from a barotraumatic, potentially injurious procedure using high voltage, direct-current (DC) shock to a safe and relatively painless one; catheter ablation procedure now carries a very low risk and is extremely effective for certain types of arrhythmia. Its efficacy rate in curing...

In the 1940s I was struck by reports about many apparently healthy middle-aged men who dropped dead instantly from heart attacks. The causes of these sudden deaths were unknown. I was interested to discover physio-chemical characteristics of individuals with predictive value for the occurrence of these fatal heart attacks. The discovery ofpreventive variables would point ways to prevent this disease. In order to find relationships between mode of life and susceptibility to heart disease contrasting populations had to be studied. Variety - not a high degree of homogeneity in culture and habits...

The electrocardiogram (ECG) remains the most accessible and inexpensive diagnostic tool to evaluate the patient presenting with symptoms suggestive of acute myocardial ischemia. It plays a crucial role in decision making about the aggressiveness of therapy especially in relation to reperfusion therapy, because such therapy has resulted in a considerable reduction in mortality from acute myocardial infarction. Several factors play a role in the amount of myocardial tissue that can be salvaged by reperfusion therapy, such as the time interval between onset of coronary occlusion and reperfusion,...

Stress Echocardiography - Its Role in the Diagnosis and Evaluation of Coronary Artery Disease - Second Edition by Thomas Marwick is a concise, practical guide for anyone new to the field of stress echocardiography or an excellent summary of the existing evidence base for the experienced user.
Dr. W.F. Armstrong described the first edition of this book in his Foreword to the first edition as "a thorough, comprehensive review of the basic and advanced concepts of stress echocardiography. This text represents an excellent starting point for individuals wishing to gain initial...

This is an important and timely volume. The history of research in homocysteine metabolism can be divided into three periods. The first phase was the exploration of the individual reactions and metabolites that characterize the transmethylation and transsulfuration sequences. The former originated with his description of the biosynthesis of methylpyridine and culminated in the work of Cantoni and Axelrod. Similarly the finding that insulin contained cystine was a potent catalyst for the metabolic and nutritional studies of Rose and du Vigneaud. The description and the definition of...

Cardiovascular diseases are the most important causes of death in the world today. In adults, the most frequent heart disease is acute myocardial infarction, which can lead to sudden death. To prevent these diseases we need to fight against their main risk factors, which include smoking, lipid disorders, hypertension, diabetes and a sedentary life-style, among others. It has been demonstrated that physical exercise or sports at any age provide notable benefits and can help to decrease other risk factors and reduce the incidence of cardio- vascular diseases. Exercise can be simply walking or...

Enthusiasm from the past notable successes with RF ablation and the demand for better therapy for the complex but common arrhythmias has carried forward the progress of catheter ablation technology. In the past few years, there has been significant progress in the development of better mapping and ablative techniques. Such progress has resulted in a steady improvement in the success of ablation of more complex atrial and ventricular tachyarrhythmias as well as our knowledge of their anatomy and pathophysiology. However, enthusiasm for finding the ideal tools for the cure of complex...

The clinical use of nuclear cardiology for the assessment of myocardial ischemia continues to grow at an unprecedented rate. Part of the reason for this growth is the technical advances in single photon emission computerized tomography (SPECT). SPECT has been shown to provide high contrast images superior to planar imaging techniques. An important and recent technical advancement in SPECT has been ECG-gated myocardial perfusion SPECT to generate simultaneous myocardial perfusion and function information from a single study. Automated, quantitative techniques have facilitated the widespread...

Coronary artery bypass surgery in the elderly: Too often or too seldom? It is a testimony to scientific advances that raising a simple inquiry today, such as whether coronary artery bypass surgery is done too often or too seldom in elderlypatients, requiresanexplorationofwhatviewsonemightholdonseveral medical as well as non-medical issues. Unlike earlier years when doctors were clinically free to decide what should be done with a patient, health has become an expensive human right, decisions about which also involve the patient, the epidemiologist, the health policy administrator,...

The importance of left ventricular hypertrophy in cardiovascular disease has gained wide recognition. Left ventricular hypertrophy is a highly important risk factor associated with major cardiovascular events, including symptomatic heart failure, particularly in patients with systemic hypertension. Over the past years much has been learned about the genetics, molecular background, prevalence, incidence and prognosis of left ventricular hypertrophy. A variety of noninvasive methods has emerged for detecting left ventricular hypertrophy and the assessment of reversal of hypertrophy. Yet, a lot...
