Examine whether integrating lung ultrasound B-lines, natriuretic peptide levels, and left atrial volume improves bedside recognition of preserved-ejection-fraction phenotype in acute heart failure.
Key Takeaways
- HFpEF was defined as left ventricular ejection fraction ≥ 50%
- ProBNP, LAVI, E/e′, body mass index, and atrial fibrillation status were recorded
- Unlike heart failure with reduced ejection fraction (HFrEF)
