Background: Adaptive servo-ventilation (ASV) is important heart failure treatment device. However, SERVE-HF trial shows that ASV treatment is harmful for heart failure patients. It is important to reconsider whether ASV is effective for heart failure, when it is possible to use ASV continuosly as heart failure treatment for elderly patients. In real world, it is true that many elderly patients have got the benefits to initiate ASV. We believe that it is key factor to educate elderly patients with regard to adherence for heart failure treatment.

Purpose: The aim in this study is to estimate whether ASV therapy is effective for elderly patients having mental frailty, which may cause poor adherence after educating importance and necessity of ASV treatment by supervisors.

Methods: After optimal medical therapy, we performed one-year follow-up study of patients with heart failure. One hundred ninety-eight patients were treated by ASV. We divided into 2 groups {Elderly patients -group (≥75 years; n=80), Control-group; n=118}. After ASV therapy, we compared the changes in brain natriuretic peptide, and ASV used time between two groups.
