About this trial
This is an interventional diagnostic trial for Heart Failure
Eligibility Criteria
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.
