Summary
Sleep dysfunction in heart failure (HF) patients is linked to medications causing drowsiness, depression, poor perceived health, and sleep hygiene. Addressing these factors may improve sleep quality for individuals with HF.
Area of Science:
- Cardiology
- Sleep Medicine
- Psychology
Background:
- Sleep dysfunction is prevalent in adults with heart failure (HF), negatively impacting their quality of life.
- Identifying modifiable factors associated with sleep dysfunction is crucial for improving patient outcomes.
Purpose of the Study:
- To identify potentially modifiable clinical, behavioral, and psychological factors associated with sleep dysfunction in adults with heart failure.
Main Methods:
- A study involving 266 participants from three U.S. sites utilized the Pittsburgh Sleep Quality Index to measure sleep dysfunction (score > 10).
- Hierarchical logistic regression analysis was employed to examine associations between sleep dysfunction and various clinical, behavioral, and psychological factors.
Main Results:
- While New York Heart Association (NYHA) functional class was an initial correlate, modifiable factors significantly associated with sleep dysfunction included medications causing somnolence (OR=2.08), depression (OR=1.83), worse perceived health (OR=1.64), and better sleep hygiene (OR=1.40).
- Sleep disordered breathing (SDB), present in 54% of subjects, was not a significant predictor of sleep dysfunction.
Conclusions:
- Sleep dysfunction in heart failure patients is associated with specific medications, depression, health perceptions, and sleep hygiene practices.
- Interventions targeting medication review, depression treatment, and improving health perceptions may enhance sleep quality in HF patients.
- Patients with sleep dysfunction may be motivated to improve their sleep hygiene, further contributing to better sleep quality.

01:27Heart Failure I: Introduction
Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...
01:22Heart Failure VI: Adjunct Therapies
Additional therapies for treating patients with heart failure (HF) may include procedural interventions, supplemental oxygen, the management of sleep disorders, and nutritional therapy.Procedural InterventionsImplantable Cardioverter-Defibrillator: For patients at risk of life-threatening arrhythmias due to severe left ventricular dysfunction, an Implantable Cardioverter-Defibrillator (ICD) can detect and terminate these arrhythmias, preventing sudden cardiac death and improving survival rates.
01:17Pathophysiology of Heart Failure
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...
01:30Heart Failure VII: Nursing Interventions
The first step in nursing management of a patient with heart failure involves thoroughly assessing the patient's medical history.Subjective Data: Obtain the patient's medical history of coronary artery disease, hypertension, myocardial infarction, and symptoms like dyspnea, orthopnea, and paroxysmal nocturnal dyspnea.Objective Data: Conduct a physical examination to identify findings such as jugular vein distention, pulmonary crackles, tachycardia, murmurs, peripheral edema, and vital signs,...
01:13Insufficient Sleep and Sleep Deprivation
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

01:30Factors Influencing Heart Rate
The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
