Heart Failure and Risk of Re-Admissions Determined by Abnormal REVEAL Parameters

Terminated

• Conditions: Heart Failure

• Registration Number: NCT01357408
• Lead Sponsor: Thomas Jefferson University

Brief Summary

The purpose of the Heart Failure and Risk of re-Admissions Determined by Abnormal REVEAL Parameters (HF RADAR) study is to evaluate the ability of cardiac rhythm (Cardiac Compass) data to predict future cardiac events in heart failure (HF) patients recently discharged after a hospitalization for heart failure who have or plan to have a implanted loop recorder (ILR), specifically, the Reveal XT device. The study will enroll 40 HF patients (with LV function ≥ 40%) admitted to an acute care facility (observation status or hospital stay) for heart failure who either have a Reveal XT device in place or plan to have the ILR device inserted for clinical indication within 14 days of discharge from the hospitalization. HF patients will be followed for 6 months. Device date will be captured during normal clinic visits and at 6 months.
