Key result
Acute heart failure prevalence and mortality vary significantly across populations due to differing definitions.
Why the study?
Differences in acute heart failure populations due to varying definitions, selection criteria, and timing of data collection affect the external validity of clinical trials and evidence-based management.
Highlights the need for standardized definitions and selection criteria in acute heart failure research to ensure clinical trials accurately represent real-world patient populations.

Variability in AHF definitions and outcomes persists; leaves open need for standardized criteria in trials and registries.
Searle et al. (2016) conducted a review in Acute heart failure. Acute heart failure prevalence ranges from 1-12% and in-hospital mortality from 4-18%, with significant population variations across trials and registries due to differing definitions.
