 PREVENT-HF is a randomized prospective study being conducted at up to 35 experienced investigative centers from the United States, Canada, and Europe. Subjects will be enrolled within 4-12 days of a discharge from a hospitalization for exacerbation of heart failure, with screening procedures to occur prior to the enrollment. Following enrollment, subjects will be randomized in a 1:1 ratio to outpatient management by either clinical assessment Standard Care Arm or ICG in addition to clinical assessment ICG Arm during the enrollment visit. ICG variables will be collected in all subjects but will be blinded in the Standard Care Arm. Each subjects study participation will last for a minimum of 24 weeks and a maximum of 52 weeks post-discharge. Four weeks after hospital discharge, subjects will visit the clinic. Remaining study visits will occur every four weeks thereafter until the subject has completed the 52-week visit or until the subject has experienced a hospitalization that has been adjudicated by the Clinical Events Committee as being a heart failure hospitalization.
