What this trial studies

This feasibility project uses wrist-worn heart-rate/activity monitors, a Bluetooth weight scale with bioimpedance, a Bluetooth blood-pressure device, and a smartphone app to remotely monitor patients after an acute HFrEF hospitalization. Clinicians will use continuous remote data to guide more rapid up-titration of guideline-directed medical therapy while watching for hypotension or bradycardia. The protocol targets earlier and more frequent medication adjustments than usual care to try to increase the proportion of patients reaching target drug doses without added safety events. The work is being conducted at Prince of Wales Hospital in Hong Kong and explicitly considers local resource limits and patient access to wearable technology.

Who should consider this trial

Good fit: Ideal candidates are adults hospitalized with acute decompensated heart failure and LVEF <40% with elevated NT-proBNP who can use or be supported to use wearable devices and a smartphone app and who have not had prior HF admissions.

Not a fit: Patients with prior HF admissions, recent or planned major cardiac interventions, expected transplant/LVAD or circulatory support, or those unable to use the required devices or app are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, this approach could help more patients reach guideline-recommended medication doses sooner and more safely, potentially lowering readmissions and improving outcomes.

How similar studies have performed: Intensive follow-up programs like STRONG-HF have shown rapid GDMT up-titration is feasible, and remote monitoring has been used in heart failure, but combining continuous wearable monitoring specifically to drive medication titration remains relatively novel and undertested.
