Mobile Clinic-Supported, Village Doctor-Led Screening and Integrated Care for Atrial Fibrillation and Heart Failure Comorbidity in Rural China (MOVE-AF HF)

AF and HF frequently coexist and are associated with poor clinical outcomes. In rural areas, limited access to echocardiography, NT-proBNP testing, and specialist care may hinder the early identification and appropriate management of HF among patients with AF. Mobile clinics may help overcome these barriers by bringing diagnostic testing and specialist support directly to rural communities. This cluster-randomized controlled trial aims to evaluate a mobile clinic-supported, village doctor-led model for HF screening and integrated management among older patients with AF in rural China. Mobile clinics equipped with echocardiography and NT-proBNP testing will support HF screening, and subsequent management will be tailored according to HF status. The study will evaluate whether this model can improve the detection of HF and reduce adverse cardiovascular events compared with routine management.
