Why the study?
Factors correlated with prognosis in HFmrEF are unclear, especially for AHF with HFmrEF, prompting an investigation into factors associated with EF improvement over 1 year.
What factors predict improvement in ejection fraction over 1 year in acute heart failure patients with mid-range ejection fraction?
Population
159 consecutive HFmrEF patients admitted for AHF
Comparison
Improved EF group (EF improved >=10%) vs non-improved EF group
Design
Single-center registry-based cohort study
Follow-up
1 year

May aid risk stratification for EF recovery in acute HFmrEF; leaves open whether targeting these factors improves outcomes.
What factors predict improvement in ejection fraction over 1 year in acute heart failure patients with mid-range ejection fraction?
In AHF patients with HFmrEF, higher serum albumin, smaller LV diastolic dimension, and in-hospital coronary angiography independently predict EF improvement, which is associated with better prognosis.
