The Frontiers in Cardiovascular Health varies between and within nations, depend- ing upon the level at which the battle is fought for better cardiovascular health. According to the 1997 World Health Report, 15 million deaths (i. e. 30% of the total number of deaths) were attributable to cardiovascular diseases and this number is on the rise. The projection for the year 2020 is quite alarming with an expected cardiovascular mortality reaching 50 million. Much of this burden is projected to occur in developing countries, more specifically in the most populous countries of the world, namely...

It is indeed ironical that in the absence of a complete knowledge of Pathophysiology, clinical cardiologists are left with no choice but to do the best they can to help the patient with the armamentarium of drugs at their disposal. But nothing could be further from truth than to treat the diagnosed end point of a disease process without a full understanding of its patho physiology. This point was eloquently made by Dr. Arnold Katz in his Presidential Address (Chapter 1) at the 8th Annual Meeting of the American Section of the International Society for Heart Research held in Winnipeg, Canada,...

Heart Hypertrophy and Failure brings together leading basic scientists and clinicians, presenting improved knowledge of the pathophysiology and treatment of the condition. The result is a synthesis of state-of-the-art information on molecular biology, cellular physiology and structure-function relationships in the cardiovascular system in health and disease. The papers presented describe fundamental mechanisms underlying changes in the cellular machinery during the development of cardiac hypertrophy and heart failure. Audience: Students, scientists, clinical and...

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...

Phospholipases generate lipid signaling molecules through their hydrolytic action on phospholipids and are known to regulate function of a variety of cells under normal and diseased conditions. While several physiological, biochemical and molecular techniques have identified key players involved in different disease processes, phospholipases have also emerged as critical players in the pathogenesis of a number of different diseases including cancer and heart disease. In addition, phospholipases are also implicated in such conditions as brain disorder/injury, kidney and immune cell...

The heart has a very high energy demand but very little energy reserves. In order to sustain contractile function, the heart has to continually produce a large amount of ATP.The heart utilizes free fatty acids mainly and carbohydrates to some extent as substrates for making energy and any change in this energy supply can seriously compromise cardiac function.It has emerged that alterations in cardiac energy metabolism are a major contributor to the development of a number of different forms of heart disease.It is also now known that optimizing energy metabolism in the heart is a viable and...

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 biological membranes of cellular organization enfold an important group of membrane proteins called the ATPases, which are not only versatile in maintaining chemical gradient and electrical potential across the membrane but also bring metabolites necessary for cell metabolism and drive out toxins, waste products and solutes that otherwise can curb cell functions. ATPases are distributed virtually in all live forms starting from unicellular to multicellular and also in viruses. There are different types of ATPases, which differ in function and structure and in the type of ions they...

Na+-K+ ATPase or Na-pump ATPase, a member of "P"-type ATPase superfamily, is characterized by association of multiple isoforms mainly of it's α- and β- subunits. At present four different α- (α-1,α-2,α-3 and α-4) and three β- (β-1, β-2, and β-3) isoforms have been identified in mammalian cells and their differential expressions are tissue specific. Regulation of Na+-K+ ATPase activity is an important but a complex process, which involves short-term and long-term mechanisms. Short-term...
