Epigenetic dysregulation of energy homeostasis drives aortic valve stenosis that is treatable with metformin Open
Aortic valve stenosis is a progressive and increasingly prevalent disease in older adults, with no approved pharmacologic therapies to prevent or slow its progression. Although genetic risk factors have been identified, the contribution of…

Predicting survival in atrial fibrillation: results from SAGE-AF Open
Two-year survival was high. This model, if validated, could have major implications for treatment of patients with AF. Patients in the large group with no or one event are at very low risk of death (under 2%). The small group with high ris…

Multiclass arrhythmia classification using multimodal smartwatch photoplethysmography signals collected in real-life settings Open
In the early stages of atrial fibrillation (AF), most cases are paroxysmal (pAF), making identification only possible with continuous and prolonged monitoring. With the advent of wearables, smartwatches equipped with photoplethysmographic …

Health behavior outcomes in stroke survivors prescribed wearables for atrial fibrillation detection stratified by age Open
Stroke survivors demonstrated a willingness to use smartwatches for AF monitoring. Importantly, among these study participants, the majority did not experience negative health behavior outcomes or decreased engagement as age increased.

Is catheter ablation associated with preservation of cognitive function? An analysis from the SAGE-AF observational cohort study Open
Objectives To examine the associations between catheter ablation treatment (CA) vs. medical management and cognitive impairment among older adults with atrial fibrillation (AF). Methods Ambulatory patients who had AF, were ≥65-years-old, a…

Income in Relation to Psychosocial Factors Among Stroke Survivors using Smartwatches for Atrial Fibrillation Monitoring Open
Our findings demonstrate that low SES is associated with worse self-reporting of physical health status, and this may influence psychosocial outcomes in smartwatch users.

Technology engagement is associated with higher perceived physical well-being in stroke patients prescribed smartwatches for atrial fibrillation detection Open
Background Increasing ownership of smartphones among Americans provides an opportunity to use these technologies to manage medical conditions. We examine the influence of baseline smartwatch ownership on changes in self-reported anxiety, p…

Anxiety, patient activation, and quality of life among stroke survivors prescribed smartwatches for atrial fibrillation monitoring Open
The prescription of smartwatches to stroke survivors for AF monitoring does not adversely affect key patient-reported outcomes. Further research is needed to better inform the successful deployment of smartwatches in clinical practice.

Self-reported efficacy in patient-physician interaction in relation to anxiety, patient activation, and health-related quality of life among stroke survivors Open
Higher self-efficacy in patient-physician interaction was associated with higher patient activation and mental health status among stroke survivors using smartwatches. Furthermore, we found no association between anxiety and smartwatch pre…
