Early Gliflozin for Elderly Patients With Acute Decompensated Heart Failure in the Emergency Department

Plain-language summary

Background: SGLT2 inhibitors reduce CHF morbidity/mortality but are underutilized in elderly patients with acute decompensated CHF (ADCHF) admitted outside cardiology departments. Objective: Assess feasibility of early ED-initiated gliflozin therapy in elderly ADCHF patients. Design: Multicenter, randomized, open-label pilot study; N=144 patients (72 per arm) across 6 EDs over 30 months. Population: Age ≥75 years, ED admission for ADCHF (symptomatic worsening, congestion, elevated natriuretic peptides), gliflozin-naïve, requiring hospitalization. Key Exclusions: Type 1 diabetes, eGFR \<25 mL/min/1.73m², cardiogenic shock, recent ACS, cardiology ward admission. Intervention: Treatment: Dapagliflozin 10mg daily within 24h + cardiac nurse telephone follow-up at 1 month Control: Standard care only Primary Outcome: Feasibility (organizational implementation, acceptability, protocol adherence, timeline compliance). Follow-up: 7-day visit (clinical assessment, NT-proBNP, echocardiography) and 3-month cardiology consultation (mortality, rehospitalization, QoL, biomarkers, safety parameters).
