Wearable Device-Assisted Remote Management to Improve Prognosis in Patients With Acute Heart Failure Complicated by Atrial Fibrillation: WARM-HF Trial (Stage 2)
A Researcher-initiated, Prospective, Open-label, Randomized Controlled Trial With a Parallel Design to Investigate the Prognostic Impact of Wearable Device-assisted Remote Management in Patients With Acute Heart Failure Complicated by Atrial Fibrillation
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.

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.

Change in GDMT score
기간: 90 days after randomization
|
The GDMT(guideline-directed medical therapy) score is a scoring system according to the combination of GDMT drugs administration and their dosages.
Renin-angiotensin system (RAS) inhibitors were scored 0 if not initiated, 1 if <50% of target dose, and 2 if 50-100% of target dose; ARNIs were scored 3 regardless of dose; BBs were scored 0 if not initiated, 1 if <50% of target dose, and 2 if 50-100% of target dose; and MRAs and SGLT2 inhibitors were scored 0 if not initiated and 2 if initiated regardless of dose.
MRAs and SGLT2 inhibitors were scored 0 if not initiated and 2 if initiated regardless of dose, resulting in a total score of 0-9.
The higher score indicated better implementation of GDMT therapy.

Changes in quality of life (QoL) using Kansas City Cardiomyopathy Questionnaire-Overall Summary (KCCQ-OS)
기간: 2 years after randomization
|
The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a 23-item questionnaire that quantifies physical limitations, symptoms, self-efficacy, social interference and quality of life for patients with congestive heart failure.
The KCCQ-OS scores range from 0 to 100, with lower scores denoting poorer quality of life.

Changes in Quality of life (QoL) using Minnesota Heart Failure Quality of Life Scale (MLHFO)
기간: 2 years after randomization
|
The Minnesota Failure Quality of Life Scale (MLHFO) was especially developed for patients with HF to measure their overall health-related quality of life.
It contains 21 questions about the impact of HF on patient's daily life.
A total score between 0 and 105 can be achieved, with a higher score indicating poorer quality of life.

Changes in quality of life (QoL) using a five-level EuroQol five-dimensional questionnaire (EQ-5D-5L)
기간: 2 years after randomization
|
The descriptive system of the EuroQol five-dimensional questionnaire(EQ-5D) comprises five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression; each dimension is described at five levels, corresponding roughly to no, slight, moderate, severe, and extreme problems.
A health profile and a single health state index value can be derived.
This index value ranges between <0 (where 0 is a health state equivalent to death; negative values are valued as worse than dead) to 1 (perfect health).
In addition, a visual analogue scale records the respondent's self-rated health status on a vertical graduated (0-100) scale.
