Wearable Device-Assisted Remote Management to Improve Prognosis in Patients With Acute Heart Failure Complicated by Atrial Fibrillation: WARM-HF Trial (Stage 2)
Sponsor: Beijing Anzhen Hospital
Summary
With the advancement of wearable technology, continuous non-invasive monitoring of vital signs, arrhythmia burden, and physical status has become increasingly feasible. Devices such as smartwatches and electrocardiogram (ECG) straps can provide real-time physiological data, offering new opportunities for remote and proactive disease management. Despite the growing availability of such real-time data, the complex interaction between atrial fibrillation (AF) and heart failure (HF) necessitates highly personalized management. However, there remains a lack of high-quality clinical evidence on how to effectively integrate wearable device data into these personalized strategies for specific patient populations. Moreover, the prognostic impact of wearable device-assisted remote management has not been comprehensively evaluated. Therefore, robust clinical studies are needed to further evaluate whether wearable device-assisted remote monitoring can improve the long-term prognosis of this population after discharge from the cardiac care unit (CCU). In this study (WARM-HF Stage 2), the investigators will conduct a prospective, multicenter, randomized controlled trial to determine whether wearable devices can reduce the composite endpoint of readmission or death in patients with HF.

Interventions
wearable device based remote management (GDMT titration for HF, rhythm control and anticoagulation management for AF)
Participants in the intervention group will be managed per current guidelines for heart failure (HF) and/or atrial fibrillation (AF). The intervention group uses real-time data for automatic triage, categorized into three subgroups: Normal subgroup: Upward titration of guideline-directed medical therapy (GDMT). Abnormal subgroup: Upward/downward GDMT titration, or volume/congestion management (dyspnea/edema) - diuretics titrated to 100% target dose or other diuretics added. Grade E alert subgroup: Emergency department (ED) or outpatient clinic visit. Efforts to maintain sinus rhythm are recommended; rate control strategies are at the discretion of physicians. Anticoagulation will be initiated, if not already started, and maintained throughout the study according to current guidelines.
