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)

Официальное название

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

Обзор

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).

Подробное описание

Heart failure with reduced ejection fraction (HFrEF) remains associated with high rates of early post-discharge events. In routine practice, timely optimisation of guideline-directed medical therapy (GDMT) and early recognition of haemodynamic deterioration are frequently limited by infrequent follow-up, delayed access to physiologic data, and variability in patient self-management.

DigiCare-HFrEF will enroll hospitalised patients with confirmed HFrEF and randomise them to either:

1. digital remote management based on an integrated platform that supports daily symptom and vital-sign reporting, algorithm-driven risk stratification, and clinician-reviewed decision support for GDMT titration and congestion management, plus standard guideline-based care; or 2. usual care with medical therapy and regular follow-up.

Randomisation will be performed through a central web-based system with stratification by participating centre and age (≤65 vs \>65 years). Given the nature of the intervention, treatment allocation is open label; however, outcome assessment and event adjudication will be performed by independent personnel blinded to treatment assignment. Participants will be followed with standardised remote assessments at 1 months and face-to-face visits at 3 months. The trial will test whether a closed-loop digital care pathway-continuous monitoring, rapid risk-informed evaluation, and standardised responses with clinician oversight-reduces major clinical events and improves GDMT optimisation.

Вмешательства

• Другое 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.
