END - VT Cohort Study

Status Recruiting

Clinical Trial Summary

Ventricular tachycardia (VT) is a life-threatening cardiac rhythm disturbance which leads to sudden cardiac death (SCD), ventricular fibrillation, electrical storm, hemodynamic collapse, and syncope. VT patients with cardiomyopathy (diseased/scarred cardiac muscle) have the highest risk of SCD (<1-4%) and recurrent VTs (15-35%). Although an implantable cardiac defibrillator (ICD) is the most effective treatment option to prevent SCD, it does not eliminate it. Without VT prevention, recurrent VT and ICD shocks may increase the risk of heart failure and death. The primary objective is to determine the optimal treatment strategy to maximize event-free survival among cardiomyopathy patients with ventricular tachycardia (VT) by the creation of a prospective, multicenter, longitudinal cohort. Also, the investigators will evaluate the epidemiology of VT, adherence to guidelines, safety, effectiveness, and cost-effectiveness of current treatment options for secondary prevention of VT in the real-world Canadian VT population.

Clinical Trial Description

The END-VT study is a multicenter, prospective, longitudinal real-world cohort study of patients with cardiomyopathy-related VT. Patients with ischemic and non-ischemic cardiomyopathy are followed from their first VT event till at least 3 years of follow-up or death, whichever is first. Outcomes of VT events are captured by ICD remote monitoring and are adjudicated by experienced clinical investigators blinded to the center and treatments. The primary objective of END-VT is to determine the optimal treatment strategy to maximize event-free survival among cardiomyopathy patients with VT. The investigator will also assess the real-world burden of disease, treatment challenges, adherence to guidelines, sex differences, and safety, effectiveness, and cost-effectiveness of VT treatments. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
