Congestive heart failure (CHF) is a disease that originates from an inadequacy of the heart to maintain blood circulation, resulting in congestion and edema in the body tissues. CHF affects about five million patients in the US alone and an estimated 23 million patients worldwide, and is the only cardiac disease that is growing in prevalence, due to both increasing survival rates of myocardial infarctions and ageing population. In this book, the authors aim to uncover the many hormonal influences on myocardial function and discuss possible aetiological mechanisms, diagnostic modalities and management strategies of the Takotsubo syndrome.
