Table 4.

Study end points

Primary efficacy end point Composite of the number of unplanned HF-related rehospitalizations or all-cause mortality 365 days after randomization (12-month time)
Primary safety end point

1. Device/system-related complications (DSRC) of the patients as a result of the attempted or successful implantation of an CardioMEMS™ sensor at the 12-month time point and

2. Freedom from sensor failures at the 12-month time

Secondary end points
