Heart failure is an ambiguous term as a technical terminology, which means sometimes an existence of ventricular dysfunction, and sometimes a decompensated heart failure with symptoms and signs due to clinical congestion. Diagnostic procedure for congestive heart failure, so called Framingham Criteria, has been no changed for approximately half a century, however, the therapeutic strategy has been improved considerably, resulting in the congestion could be managed and heart failure patients released from symptoms and signs by congestion. Ironically, that makes the word heart failure more complex and obscure. Chronic heart failure is a new concept that is constructed by NYHA functional class as a degree of symptoms and by stage of heart failure as a degree of remodeling of myocardium due to neurohumoral activation, renin-angiotensin-aldosterone system and sympathetic nerve system, and would be able to cover all conditions of heart failure and also to provide the managements for patients in each stage. More understanding for the concept of chronic heart failure is beneficial regarding clinical managements of heart failure for not only cardiologists, but also all attending physicians.
