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.

Official Title

BIO-LIBRA Clinical Study


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.
