Physical activity benchmarks for implantable loop recorder patients: The role of ILRs in cardiovascular disease management

Implantable loop recorders (ILRs) are subcutaneous devices that currently serve primarily as a diagnostic tool for a variety of cardiovascular conditions. However, the utility of ILRs for data insights in disease management has not beesn well explored. This study aimed to fill that gap by exploring how data collected from ILRs, particularly physical activity (PA) trends derived from the accelerometer function, could be used to better manage cardiovascular diseases. Although trends in PA have demonstrated the potential to inform proactive, effective interventions for cardiovascular disease,1 established norms for PA levels remain undefined for patients with an ILR, and more specifically for patient subgroups defined by their indication for the device.
