About this trial

This is an interventional diagnostic trial for Heart Failure

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Patients meeting at least 1 of 3 criteria will be included in the study:

    • Patients with symptomatic systolic or diastolic heart failure who in the clinician's judgment have a high likelihood of undergoing serial right heart catheterizations to aid in clinical management of their heart failure
    • Patients with dyspnea on exertion in whom exercise hemodynamics is indicated to diagnose diastolic dysfunction
    • Patients who have or will be implanted with a pulmonary artery pressure monitor
  • Patient is 18 years of age or older
  • Patient (or patient's legally authorized representative) is willing and able to provide written informed consent
  • Patient is willing and able to comply with the protocol, including follow-up visits and Carelink transmissions.

Exclusion Criteria:

  • Patient has an existing Medtronic implantable cardiac device
  • Patient has a left ventricular assist device (LVAD)
  • Patient is pregnant (all females of child-bearing potential must have a negative pregnancy test within 1 week of enrollment)
  • Patient is enrolled in another study that could confound the results of this study, without documented pre-approval from a Medtronic study manager

Outcomes

Primary Outcome Measures

Comparison of Reveal LINQ™ Subcutaneous Impedance (Units of Ohms) With Pulmonary Artery Pressure (Units of mmHg) From a Swan-Ganz Catheter During Right Heart Catheterization Procedures in Patients With Heart Failure.
The primary objective was to characterize the relationship between changes in Reveal LINQ™ subcutaneous impedance and right heart hemodynamic measurements, resulting from: 1) short-term drug and/or exercise challenges during right heart catheterization procedures or 2) long-term daily trends of physiologic data, in patients with heart failure.

Secondary Outcome Measures

Characterization of the Changes in Reveal LINQ™ Subcutaneous Impedance (Units of Ohms) Prior to Any Acute Decompensated Heart Failure Events.
The primary objective was to characterize the relationship between changes in Reveal LINQ™ subcutaneous impedance and right heart hemodynamic measurements, resulting from: 1) short-term drug and/or exercise challenges during right heart catheterization procedures or 2) long-term daily trends of physiologic data, in patients with heart failure.
Characterization of the Changes in Reveal LINQ™ Activity (Units of Hours Per Day) Prior to Any Acute Decompensated Heart Failure Events.
A heart failure event is defined as any cardiovascular-related (including hypervolemia) 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
