What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CardioMEMS HF SystemDevice

    The CardioMEMS HF System provides pulmonary artery (PA) hemodynamic data to monitor and manage HF subjects. The CardioMEMS HF System measures PA pressure which clinicians use to initiate or modify HF treatment.

Study groupRoleWhat they receive
Primary CohortThe Primary Cohort will include NYHA Class II heart failure subjects receiving a CardioMEMS PA Sensor implant in the commercial setting.
Receives: Device: CardioMEMS HF System
Full CohortThe Full Cohort will include both NYHA Class II and Class III heart failure subjects receiving a CardioMEMS PA Sensor implant in the commercial setting.
Receives: Device: CardioMEMS HF System

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Two-Year Survival in NYHA Class II subjects without a history of severe renal disease

    Compare survival in a subset of subjects from the Primary Cohort without a history of severe renal disease to a pre-specified performance goal of 71.7% survival at 2 years

    Measured: 2 years

Secondary outcomes (1)
  1. Two-Year Survival in NYHA Class II and III subjects without a history of severe renal disease

    Compare survival in a subset of subjects from the Full Cohort without a history of severe renal disease to a pre-specified performance goal of 68.6% survival at 2 years

    Measured: 2 years
