Bedside Ultrasound-guided Volume Management and Discharge Timing for Patients With Heart Failure During Hospitalization: A Randomized Controlled Trial

Unique Combination: Simultaneously tracks IVC collapsibility index (\>50%) + pulmonary B-line counts (≤5) to guide therapy, unlike studies using either metric alone.Thresholds Tested: Compares ESC consensus thresholds (IVC \<2.1cm) vs. exploratory Asian-optimized thresholds (IVC \<1.8cm) in Subgroup B.

Discharge based on symptoms/signs alone: Clinical congestion score ≤2 + NYHA class ≤II
