Digital Remote Management Versus Usual Care for Optimization of Guideline-directed Medical Therapy in Patients With Heart Failure and Reduced Ejection Fraction: a Multicentre, Randomised, Controlled Trial (DigiCare-HFrEF)

DigiCare-HFrEF is an investigator-initiated, multicentre, randomised, open-label, endpoint-blinded, superiority trial designed to evaluate whether a structured digital remote-management platform can optimise guideline-directed medical therapy (GDMT) in patients with heart failure with reduced ejection fraction (HFrEF) after hospital discharge. Eligible adults (≥18 years) with a confirmed diagnosis of HFrEF within the past 3 months (left ventricular ejection fraction ≤40%) who are not optimally treated with GDMT-defined as at least two of the four foundational drug classes (ACEi/ARB or ARNi, β-blocker, MRA, SGLT2 inhibitor) either not initiated or prescribed at \<50% of the target dose-will be randomly assigned in a 1:1 ratio to digital remote management or usual care. In the intervention arm, patients will report symptoms and key physiologic measures (e.g., blood pressure, heart rate, and body weight) via the platform; an algorithm will perform risk stratification and generate GDMT optimisation suggestions and decongestion prompts, as well as a comprehensive management for core health metrics, which are reviewed and confirmed by clinicians before implementation. The primary endpoint is the change in GDMT score from baseline to 3 months (ΔGDMT).
