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

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic

Primary Outcome Measures:
  • Clinically significant arrhythmias reported by ELR at acute monitoring period [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Clinically significant arrhythmias reported by ELR [ Time Frame: 8-10 weeks post MI ] [ Designated as safety issue: No ]
    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.

Estimated Enrollment: 300
Study Start Date: April 2014
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Patients must provide written informed consent/data release consent to participate in the study.
  2. Acute Myocardial Infarction (STEMI or non-STEMI) within the last 10 days based on ESC/ACC/AHA/WHF criteria (Thygesen, 2012) matching the following criteria:

    Rise and/or fall of cardiac biomarker values [preferably cardiac troponin (cTn)] with at least one value above the 99th percentile upper reference limit (URL) and with at least one of the following:

    1. Symptoms of ischaemia.
    2. New or presumed new significant ST-segment-T wave (ST-T) changes or new left bundle branch block (LBBB).
    3. Development of pathological Q waves in the ECG.
    4. Imaging evidence of new loss of viable myocardium or new regional wall motion abnormality.
    5. Identification of an intracoronary thrombus by angiography.
  3. LVEF ≤35% as measured by echocardiography (Simpson's method, biplane) one day before or on the day of hospital discharge

Exclusion Criteria:

  2. Age < 18 years
  3. Psychologically incapacitated
  4. Patient is pregnant, or is expecting to become pregnant during the course of the trial per Investigator discretion.
  5. Patients contraindicated for NUVANT system
  6. Comorbidities likely to limit survival to less than the minimal study duration (12 months)
  7. Participation in an investigational study with known or suspected cardiac effect expected to confound the results of this study (e.g. stem cell trials, stent trials, cardiac intervention trials, drug trials)
  8. Patients with an existing pacemaker or ICD implanted.
  9. Patients that are dialysis dependent at discharge
