Brief Summary:
The purpose of the INSPIRE-ELR study is to characterize arrhythmias in post MI low EF (≤35%) patients in the acute phase (at discharge from hospital after index MI) and chronic phase (at 8-10 weeks after index MI) and to correlate with patients at high risk of all-cause mortality or sudden cardiac death (SCD) at 1 year.

Condition or disease Intervention/treatment
Post Myocardial Infarction Patients With Ejection Fraction Less Than or Equal to 35% Device: External Loop Recorder

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 250 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: IdeNtifying High riSk Patients Post Myocardial Infarction With REduced Left Ventricular Function Using External Loop Recorders (INSPIRE-ELR Study)

Arm Intervention/treatment
External Loop Recorder
This is a non-randomized study. All the patients will be enrolled will received the ELR system.
Device: External Loop Recorder
Other Names:
  • NUVANT Mobile Cardiac Telemetry (MCT) system (CorventisTM)
  • SEEQ™ External Cardiac Monitor (ECM) system (Medtronic, Inc., Minneapolis, MN)

Primary Outcome Measures :
  1. Clinically significant arrhythmias reported by ELR at acute monitoring period [ Time Frame: 12 months ]

Secondary Outcome Measures :
  1. Clinically significant arrhythmias reported by ELR [ Time Frame: 8-10 weeks post MI ]
    The study is designed to collect the incidence of any post-MI arrhythmias. If an arrhythmia is detected, the patient will be managed per the physician's discretion.

  • Patients with an existing pacemaker or ICD implanted.
  • Patients that are dialysis dependent at discharge
