This study explores the hypothesis that wearable defibrillators can impact mortality by reducing sudden death during the first three months after a heart attack in persons with high risk for life-threatening arrhythmias.

Condition Intervention Phase
Myocardial Infarction
Ventricular Dysfunction
Sudden Death
Ventricular Tachycardia
Ventricular Fibrillation
Device: wearable defibrillator
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Outcomes Assessor
Primary Purpose: Treatment
Official Title: Prevention of Sudden Death After Myocardial Infarction Using a LifeVest Wearable Cardioverter-defibrillator

Further study details as provided by University of California, San Francisco:

Primary Outcome Measures:
  • Sudden death mortality [ Time Frame: three months after myocardial infarction ]

Secondary Outcome Measures:
  • Cardiovascular, all-cause, and other cause specific mortality [ Time Frame: three months after myocardial infarction ]
  • incidence of ventricular arrhythmias [ Time Frame: three months after myocardial infarction ]
  • adverse events attributable to wearable defibrillator use [ Time Frame: three months after myocardial infarction ]
  • compliance with wearable defibrillator use [ Time Frame: three months after myocardial infarction ]

Estimated Enrollment: 2300
Study Start Date: July 2008
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Wearable defibrillator
subjects will use a wearable defibrillator for three months following myocardial infarction
Device: wearable defibrillator
LifeVest wearable defibrillator
Other Names:
  • LifeVest
  • wearable cardioverter-defibrillator
  • WCD
  • WD
No Intervention: Conventional treatment

Detailed Description:
In patients with ventricular dysfunction immediately following myocardial infarction, sudden death may be responsible for up to 50% of total mortality. Wearable defibrillators may reduce sudden death by providing immediate detection and treatment of ventricular arrhythmias. This study is design to demonstrate a reduction in sudden death measured at three months following myocardial infarction among patients who have ventricular dysfunction.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients identified in the hospital or within 7 days after discharge with a diagnosis of an acute MI (STEMI or Non-STEMI)
  • LV ejection fraction ≤35% determined at the following time point:

    1. If no PCI within the first 8 hours following the MI: ≥ 8 hours after MI
    2. If acute PCI occurs within 8 hours of MI: ≥8 hours after PCI
    3. If CABG is planned (before or within 7 days of discharge), wait to enroll and then use the most recent assessment at least 48 hours post CABG
  • Age ≥ 18 years

Exclusion Criteria:

  • Existing ICD or indication for an ICD at the time of screening
  • Existing unipolar pacemakers/leads
  • Chronic renal failure requiring hemodialysis after hospital discharge
  • Chest circumference too small or too large for LifeVest garment*
  • Participants discharged to an institutional setting with an anticipated stay > 7 days
  • Pregnancy
  • Inability to consent
  • Any other condition or circumstance that in the judgment of the clinician makes the participant unsuitable for the study.
