What's Next for Acute Heart Failure Research?

Abstract

Each year over one million patients with acute heart failure (AHF) present to a United States emergency department (ED). The vast majority are hospitalized for further management. The length of stay and high post-discharge event rate in this cohort has changed little over the last decade. Therapeutic trials have failed to yield substantive improvement in post-discharge outcomes, subsequently, AHF care has changed little in the last 40 years. Prior research studies have been fragmented as either "inpatient" or "ED-based". Recognizing the challenges in identification and enrollment of ED patients with AHF, and the lack of robust evidence to guide management, an AHF clinical trials network was developed. This network has demonstrated, through organized collaboration between cardiology and emergency medicine, that many of the hurdles in AHF research can be overcome. The development of a network that supports the collaboration of acute care and HF researchers, combined with the availability of federally funded infrastructure, will facilitate more efficient conduct of both explanatory and pragmatic trials in AHF. Yet many important questions remain, and in this document our group of emergency medicine and cardiology investigators have identified four high priority research areas.
