Acute heart failure syndromes: current state and framework for future research.

Acute heart failure syndromes (AHFS) poses unique diagnostic and management challenges. This syndrome has recently received attention from researchers, clinicians, regulatory agencies, and the pharmaceutical industry. However, there is no consensus on its definition, epidemiology, pathophysiology, appropriate therapeutic options, and directions for future research. This document is the result of the First and Second International Workshop on Acute Heart Failure Syndrome that took place in May 2004 and April 2005. At these workshops, a selected group of physician scientists, epidemiologists, clinicians, regulatory and governmental funding agencies, and industry representatives from North and South America and Europe convened to develop a platform for future investigative approaches and management of AHFS. Subsequently, emergency physicians, who play a pivotal role in the early management of AHFS, contributed to this document.
