Reveal LINQ™ Heart Failure

The purpose of the LINQ™ HF study is to characterize Reveal LINQ™ derived data from patients with heart failure by assessing the relationship between changes in LINQ™ derived data and other physiologic parameters with subsequent acute decompensated heart failure (ADHF) events.

About this study

The study is a prospective, non-randomized, multi-center, observational, pre-market clinical study. The study is expected to be conducted at up to 30 centers in the United States. Up to 300 subjects will be enrolled to achieve approximately 40 heart failure events (no more than two per subject will contribute to the cumulative total). Study subjects will be followed for up to 3 years post-insertion or until official study closure defined as when Medtronic and/or regulatory requirements have been satisfied per the Clinical Investigation Plan and/or by a decision by Medtronic or regulatory authority, whichever occurs first. The expected study duration is approximately 4 years representing 1.5 years of enrollments and 2.5 years of follow-up.

The LINQ™ HF study is a Non-Significant Risk Investigational Device Exemption (IDE) study. The study is utilizing the Reveal LINQ™ device with an investigational LINQ™ HF RAMware download.

  • Patient is NYHA Class III, per most recent assessment or at any time within 30 days prior to enrollment
  • Patient had a HF event (HF event defined as meeting any one of the following three criteria):
  • Admission with primary diagnosis of HF within the last 6 months, OR

Primary outcomes

  1. Number of Participants With Reveal Device Experiencing an Initial Acute Decompensated Heart Failure (ADHF) Event

    Time frame: 30 days post-Reveal LINQ insertion to 3 years post-implant

    A heart failure (HF) event is defined as any cardiovascular-related Health Care Utilizations (HCUs) for any one of the following events.

    • Admission with primary diagnosis of HF
    • Intravenous HF therapy (e.g. IV diuretics/vasodilators) or ultrafiltration at any one of the following settings:
    • Admission with secondary/tertiary diagnosis of HF
    • Emergency Department
    • Ambulance
    • Observation Unit
    • Urgent Care
    • HF/Cardiology Clinic

    Up to 2 ADHF events were intended to be allowed per subject:

    • One had to be at least 30 days post-Reveal LINQ insertion and is summarized in this section, and
    • A possible second ADHF event must be greater than 90 days after the first ADHF event

    Only subjects with a LINQ device were included in the analysis, as the goal was to acquire LINQ-collected data leading up to the ADHF event.

  2. Number of Participants With a LINQ Device Experiencing a Second Acute Decompensated Heart Failure (ADHF) Events

    Time frame: > 90 days following first Acute Decompensated Heart Failure event to 3 years post-implant

    A heart failure (HF) event is defined as any cardiovascular-related Health Care Utilizations (HCUs) for any one of the following events.

    • Admission with primary diagnosis of HF
    • Intravenous HF therapy (e.g. IV diuretics/vasodilators) or ultrafiltration at any one of the following settings:
    • Admission with secondary/tertiary diagnosis of HF
    • Emergency Department
    • Ambulance
    • Observation Unit
    • Urgent Care
    • HF/Cardiology Clinic

    Up to two ADHF events per subject were intended to be evaluated. The first must be at least 30 days post-Reveal LINQ insertion, and the second, summarized in this section, must be greater than 90 days following the first ADHF event.

    Only subjects with a LINQ device were included in the analysis, as the goal was to acquire LINQ-collected data leading up to the ADHF event.
