Study Summary

Nearly one-third of US adults have poor sleep quality. Sleep quality refers to sleep efficiency, sleep latency, sleep duration, wake after sleep onset, and movement during the night. Specifically, sleep efficiency (SE) measures how well an individual utilizes their time in bed for restorative sleep and it highly depends on actual sleep duration. Reduced SE is associated with a greater risk for heart failure (HF), which affects ~6.7 million adults in the US alone. HF with preserved ejection fraction (HFpEF) accounts for about half of all HF diagnoses and is associated with poor prognosis (30-50% 5-year mortality from diagnosis) and severely reduced quality of life (QoL). Long-term goal for the investigators is to identify sleep modulation as a potential therapeutic target to improve QoL in HFpEF, with poor SE being present in ~60% of patients with HFpEF. The study is aimed to see if the sleep modulation is feasible and modulating sleep can improve the QoL and functional capacity along with the reduction of inflammation among subjects with HFpEF.

Study Description

The investigators plan a 2-week single-arm open-label feasibility study in 17 subjects with HFpEF with a 1-week run-in phase (3 weeks total duration) with a sleep extension intervention combined with sleep hygiene training to improve SE in patients with symptomatic HFpEF. The investigator's primary endpoint is to increase sleep duration and efficiency with this intervention.
