Galectin-3 Is Independently Associated With Short-Term Mortality and Identifies Low-Risk Patients With Acute Dyspnea in the Emergency Department: A Retrospective Cohort Study

Gal-3 NPX was independently associated with 30-day mortality in patients with acute dyspnea. Although its addition yielded only a modest, non-significant improvement in overall risk prediction, Gal-3 may be useful for ruling out short-term mortality, supporting its potential role as a negative prognostic marker in the ED setting.
