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)
Digital Remote Management: Participants will use a digital remote-management platform to report symptoms and key physiologic variables (e.g., blood pressure and body weight). The platform applies a predefined risk-stratification algorithm and provides clinician-facing decision support for GDMT titration and congestion management. A comprehensive management for core health metrics will also be provided. Clinicians review and confirm recommendations before they are communicated to patients.
Study summary
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).

Inclusion Criteria:
1. Adults aged ≥18 years.
2. Hospitalised at a secondary or tertiary hospital with established heart failure care capacity.
3. Diagnosed with HFrEF within the past 3 months according to the 2022 ACC/AHA/HFSA guideline diagnostic pathway, including: LVEF ≤40% by echocardiography; typical heart-failure symptoms and/or signs; and exclusion of non-HF causes of symptoms.
4. Not optimized on guideline-directed medical therapy (GDMT) at enrollment, defined as at least two of the following four foundational drug classes not initiated or administered at \<50% target dose.
5. Written informed consent provided.
Exclusion Criteria:
1. Absolute contraindication to heart failure pharmacotherapy.
2. History of heart transplantation or currently on a transplant waiting list.
3. Receiving or planning implantation of a left ventricular assist device.
4. Pregnant or breastfeeding women.
5. Organ transplantation within the past 12 months.
6. Unable to use the remote management platform as required (e.g., cognitive impairment or lack of caregiver support).
7. Unable to perform blood pressure or body-weight monitoring (e.g., severe limb disability).
8. Unable to express willingness or comply with follow-up requirements (e.g., unable to use internet-enabled devices).
9. Any other condition judged by the investigator to make the patient unsuitable for participation.
Primary outcome measure(s)
Change in hear failure GDMT score (ΔGDMT) from baseline to 3 months — 3 months after randomization The Guideline-Directed Medical Therapy (GDMT) Score is a modified heart-failure pharmacotherapy score based on five medication classes:
1. angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEi/ARB),
2. angiotensin receptor-neprilysin inhibitor (ARNI),
3. beta-blockers (BB),
4. mineralocorticoid receptor antagonists (MRA), and
5. sodium-glucose cotransporter-2 inhibitors (SGLT2i).
Dosing levels are scored as follows:
* ACEi/ARB: 0 = none; 0 = \<50% target dose; 1 = ≥50% target dose.
* ARNI: 0 = none; 1 = \<50% target dose; 2 = ≥50% target dose.
* Beta-blocker: 0 = none; 1 = \<50% target dose; 2 = ≥50% target dose.
* MRA: 0 = none; 1 = \<50% target dose; 2 = ≥50% target dose.
* SGLT2 inhibitor: 0 = none; 2 = therapeutic dose (no low-dose category). The total GDMT Score ranges from 0 to 9, with higher scores indicating more complete, optimized, and guideline-concordant HF medical therapy.
