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.
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.

| Demonstrate the feasibility of a gradual sleep extension strategy combined with sleep hygiene training using a wearable device | To assess the sleep modulation, We will assess sleep quality using the two wearable devices. A research-based accelerometer (GT9X Link, ActiGraph, FL) will be used on the wrist using a 24-hour per day for 7 days wear protocol except shower and swimming for the 1-week run-in phase. The same wear protocol will be implemented for the 2 weeks of intervention. Sleep duration and rest in bed will be automatically detected by the Actigraph and translated by Actilife software with an epoch of 30 seconds. | Between baseline and 2 weeks of the intervention |
| Demonstrate the feasibility of a gradual sleep extension strategy combined with sleep hygiene training using a sleep journal | A sleep diary will be used to reinforce the assessment conducted by accelerometer. A sleep diary is a record of your sleep behaviors, quality and schedule. It can help you to gauge your total sleep time, mark your breaks in sleep and when they occur and track changes in your quality of sleep. | Between baseline and 2 weeks of the intervention |
| Demonstrate the feasibility of a gradual sleep extension strategy combined with sleep hygiene training using the Pittsburgh Sleep Quality questionnaire. | Pittsburgh Sleep Quality questionnaire: Pittsburgh Sleep Symptom Questionnaire - Insomnia (PSSQ_I) has 13 self-rated questions. Only questions 1,2 or 5 are used to determine the presence, frequency AND duration of sleep symptom criteria. Questions 6-13 are used to identify significant daytime consequences of the sleep complaint. Adding up the average scores of the seven factors gives a global PSQI score from 0 to 21, with 0-4 indicating "good" sleep and 5-21 indicating "poor" sleep | Baseline (week 1) and at the end of the follow-up period (week 3) |
| Demonstrate the feasibility of a gradual sleep extension strategy combined with sleep hygiene training using the Epworth Sleepiness Scale at baseline and at the end of the follow-up for subjectively assess sleep quality. |

Epworth Sleepiness Scale: The Epworth sleepiness scale results range from 0 to 24. Results from 0 to 10 show average (normal) daytime sleepiness. A result under 10 may not be cause for concern or it could identify you have trouble sleeping (insomnia). A result from 11 to 24 indicates excessive (abnormal) daytime sleepiness. |
