Measure
Active Arm
Subjects will undergo remote monitoring, remote monitoring data will be analyzed on a predictive platform, alerts indicating heart failure worsening shared with treating team, and algorithmic response to alerts implements. Remote monitoring and predictive analytics: Subjects will undergo remote monitoring, remote monitoring data will be analyzed on a predictive platform, alerts indicating heart failure worsening shared with treating team, and algorithmic response to alerts implements.
Control
Subjects will wear a sensor, but data from the sensor will not generate alerts and will not be shared with the treating team. Sham comparator: Subjects will wear a sensor, but data from the sensor will not generate alerts and will not be shared with the treating team.
