Smart-device based atrial fibrillation risk factor tracking for optimising risk factor modification in patients with atrial fibrillation – the SMART-AF study

Background: The treatment of cardiovascular risk factors, termed risk factor modification (RFM), has been identified as a crucial component of atrial fibrillation management, This study seeks to utilise the accessibility and advances in technology to help participants engage and track their progress towards optimal RFM. In addition to standard written and verbal information on the importance of RFM for AF, the intervention will consist of access to a digital RFM tracking platform. This platform will be a web-based tool that can be accessed on a phone or computer, aiming for at least weekly engagement. Adherence to the intervention can be assessed through weekly participant input into the digital RFM tracking platform. Based on performance compared to ideal RFM targets, participants will receive a weekly composite score (out of 100), with a score of 100 aligned with meeting RFM targets across the seven domains (body mass index (BMI), Hba1c, obstructive sleep apnea (OSA) status/continuous positive airway pressure (CPAP) use, alcohol use, cigarette use, exercise, blood pressure). Following RFM logging, through the web-based application participants will receive a visual representation of week-to-week progress and advice on how to best improve their RFM forming a "digital care plan". Written and verbal information part of the digital care plan will be developed for this study. The intervention will be 12 months in duration.
