  • Heart Failure NYHA Class III


The ALLEVIATE-HF study is a prospective, randomized, multi-site, interventional, investigational device exemption (IDE) study. The purpose of the study is to gain experience with utilization of an integrated device diagnostic-based risk stratification algorithm to guide patient care in subjects with NYHA class II and III heart failure.

Study summary:

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 300 subjects at up to 30 sites in the US, and will characterize the safety of the patient management pathway. Subjects will be followed for a minimum of 7 months, and until study closure.
