Conditions

Atrial Fibrillation (AF), Heart Failure, Progression, Screening

Brief summary

Atrial fibrillation (AF) is a common arrhythmia in aging populations and is strongly associated with an increased risk of heart failure (HF) and adverse cardiovascular outcomes. However, early detection of HF among patients with AF remain inadequate in rural settings. This study aims to screen for HF among older adults with AF in rural China and to conduct long-term follow-up in order to observe the disease progression in patients with AF. This study will recruit at least 2,500 elderly individuals aged between 65 and 80 years, with confirmed diagnoses of AF, residing in rural areas. Participants will undergo HF screening using NT-proBNP testing and echocardiographic assessment. Additionally, data will be collected on electrocardiographic signals, seismocardiography, voice, and demographic characteristics. Following data collection, participants will be followed up every three months to monitor the incidence and progression of HF as well as the occurrence of adverse cardiovascular events.
