Heart failure (HF) is a condition in which a problem with the structure or function of the heart impairs its ability to supply sufficient blood flow to meet the body's needs. This book presents topical research in the study of heart failure including the potential use of inotropic agents in the treatment of congestive heart failure; radiation induced hazards in intervention cardiology; the utilisation of different imaging methods to assess myocardial viability; the molecular mechanisms underlying the pathogenesis of heart failure; health-related quality of life issues for heart failure patients and others.
