Myocardial Ischemia : From mechanisms to therapeutic potentials Effective new treatments of heart disease are based on a refined understanding of cellular function and the hearts response to environmental stresses. Not surprisingly therefore the field of experimental cardiology has experienced a phase of rapid exponential 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 transcriptional 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 investigators 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.
