Acute heart failure : An unmet medical need

Despite recent advances in the management of heart failure with reduced ejection fraction (HFrEF), the burden of acute heart failure (AHF) remains significant with a high morbidity and mortality that has not been improved by any treatment modality. A meta-analysis summarized the study results on the effects of tolvaptan on AHF, which failed to demonstrate an improvement in short-term and long-term mortality, length of hospital stay and reduced frequency of worsening heart failure (WHF). Similar trial results were also reported in other AHF studies, such as the ASCEND-HF and the RELAX-AHF-2 trials. In view of these inconclusive studies it is evident that improving the prognosis of AHF patients remains an unmet medical need. Further efforts should focus on organ damage protection, individualized treatment, patient benefits and standardized management programs, including immediate identification and management of cardiogenic shock and establishment of HF networks for close monitoring of AHF patients.
