Brief Summary:
The purpose of this registry is to prospectively assess outcomes of device-treated ventricular tachyarrhythmias and all-cause mortality in non-ischemic cardiomyopathy patients indicated for ICD or CRT-D implantation for the primary prevention of sudden cardiac death. Differences in outcomes will be evaluated by sex and by device type.

Detailed Description:

The BIO-LIBRA Study will gather information about women and men with non-ischemic cardiomyopathy who are treated with implanted ICD and CRT-D devices from many locations across the United States. The BIO-LIBRA Study will look at the results of treatment in women and men enrollees. The two primary goals are: 1) to learn if there are differences in treatment response based on the patient's sex; and 2) to learn if there are differences in patient outcomes based on device type.

There is a special focus on women in the BIO-LIBRA Study. Usually, only about 25% of people in prior device studies have been women. Yet heart disease is the number-one cause of death for women - one in three deaths each year. The BIO-LIBRA Study would like to have a more balanced study which includes more women than in prior studies. The goal is for at least 40% of the people participating in the study to be women.

The study will observe up to 1,000 women and men over a three-year period following the device implant. Utilizing information collected at annual doctor visits and scheduled transmission reports from the implanted device in between these visits, the BIO-LIBRA Study will be able to evaluate some of the common risks of non-ischemic cardiomyopathy.

    Evaluate the combined risk of all-cause mortality and treated ventricular tachycardia (VT) or ventricular fibrillation (VF) events by sex and by implanted device type


Secondary Outcome Measures :
  1. Rate of all-cause mortality [ Time Frame: 3 years post-implant ]
    Rate of all-cause mortality will be analyzed for the total cohort, as well as by sex and by the implanted device type

  2. Rate of treated ventricular tachycardia (VT) or ventricular fibrillation (VF) events [ Time Frame: 3 years post-implant ]
    Rate of treated ventricular tachycardia (VT) or ventricular fibrillation (VF) events will be analyzed for the total cohort, as well as by sex and by the implanted device type

  3. Rate of cardiac death [ Time Frame: 3 years post-implant ]
    Rate of cardiac death will be analyzed for the total cohort, as well as by sex and by the implanted device type

  4. Rate of sudden cardiac death [ Time Frame: 3 years post-implant ]
    Rate of sudden cardiac death will be analyzed for the total cohort, as well as by sex and by the implanted device type

  5. Comparison of the Seattle Proportional Risk Model (SPRM) predicted incidence of sudden death to the observed incidence of death [ Time Frame: 3 years post-implant ]
    Comparison of the Seattle Proportional Risk Model (SPRM) predicted incidence of sudden death to the observed incidence in this patient population


Other Outcome Measures:
  1. Evaluation of cardiovascular and diabetes medication use and dosage during the study [ Time Frame: 3 years post-implant ]
    Evaluation of cardiovascular and diabetes medication use and dosage during the study in both ICD and CRT-D patients stratified by sex

  2. Assessment of left ventricular reverse remodeling by echocardiography at 12 months for CRT-D patients [ Time Frame: 12 months post-implant ]
    Assessment of left ventricular reverse remodeling using echocardiography at 12 months for patients implanted with CRT-D as characterized by the change compared to the baseline assessment of the left ventricular ejection fraction (LVEF) and left ventricular end-systolic volume (LVESV)

  3. Rate of inappropriate ICD therapy [ Time Frame: 3 years post-implant ]
    Analysis of the rate of inappropriate ICD therapy (ICD delivered ATP or shock for rhythms other than VT/VF) in both ICD and CRT-D patients stratified by sex

  4. Rate of ventricular tachycardia (VT) or ventricular fibrillation (VF) events treated with shock only [ Time Frame: 3 years post-implant ]
    Analysis of the rate of ventricular tachycardia (VT) or ventricular fibrillation (VF) events treated with shock only by sex and by device type

  5. Rate of observed major complications [ Time Frame: 3 years post-implant ]
    Evaluation of the observed major complication rates, including the overall rate and rates of individual major complications in both ICD and CRT-D patients stratified by sex
