Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will enroll 30 subjects recruited from the electrophysiology device clinic at the VA medical center. All patients will have a pre-existing implantable cardioverter defibrillator and a diagnosis of cardiomyopathy with left ventricular systolic function of 35% or less by echocardiogram done within 3 years of the time of enrollment. 10 patients who have had no device-monitored ventricular fibrillation/ ventricular tachycardia for the 3 months prior to recruitment will comprise a group of controls. 20 patients will comprise a group of patients with high burden of ventricular arrhythmias, defined as patients with at least one sustained episode of ventricular tachycardia/ ventricular fibrillation requiring implantable cardioverter-defibrillator therapies in the 3 months preceding study enrollment. This information will be obtained from device interrogation at the time of recruitment. Patients will provide a fecal sample for analysis at the time of enrollment.
