Clinical Trial Summary

The ALLEVIATE-HF study is a prospective, randomized, controlled, blinded, multi-site, interventional, investigational device exemption (IDE) pivotal study. The purpose of the study is to demonstrate the safety and efficacy of a patient management pathway that utilizes an integrated device diagnostic-based risk stratification algorithm to guide patient care in subjects with NYHA class II and III heart failure, and to demonstrate the safety of the Reveal LINQ™ system and procedure in the study population.

Description:

The study will utilize the market released Reveal LINQ™ Insertable Cardiac Monitor with an investigational ALLEVIATE-HF RAMware download. The study will enroll up to 900 subjects at up to 75 sites in the US. Subjects will be followed until the last enrolled subject is followed for 7 months or until the end of the study, whichever occurs first, or until time of study exit or death as applicable, but no longer than 36 months.
