Heart Failure I: Introduction

Heart 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...

Heart Failure V: Medical Management

Heart Failure V: Medical Management

Medical Management of Acute Decompensated Heart Failure (ADHF)The primary goals of therapy for patients hospitalized with acute decompensated heart failure (ADHF) include:Relieving symptomsOptimizing volume statusSupporting oxygenation and ventilationMaintaining cardiac output (CO) and end-organ perfusionIdentifying and addressing the cause of ADHFPreventing complicationsProviding patient education on factors precipitating HF exacerbationPlanning for dischargeOngoing monitoring and assessment...

Heart Failure VI: Adjunct Therapies

Heart 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.

Heart Failure VII: Nursing Interventions

Heart 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,...

Heart Failure IV: Classification and Diagnostic Evaluation

Heart Failure IV: Classification and Diagnostic Evaluation

Heart failure can be classified in various ways, with the most common classifications based on physical activity limitations, disease progression, severity, and treatment strategies.The Functional Classification of Heart Failure divides patients into four categories based on physical activity limitation due to symptom burden.Class I: Patients in this class have cardiac disease but no physical activity limitations. Ordinary activities like walking, climbing stairs, or routine tasks do not cause...

Heart Failure III: Clinical Manifestations

Heart Failure III: Clinical Manifestations

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

Background:

Heart failure (HF) management necessitates effective patient self-care, with telehealth offering a promising avenue for monitoring and support.
Conversational agent technologies, particularly those with voice interfaces, present an accessible option for facilitating telehealth in HF patients due to their ease of use.

Purpose of the Study:

To investigate patient engagement with voice interface telehealth technologies in heart failure (HF) management.
To identify patient characteristics associated with increased utilization of these technologies.

Main Methods:

A comparative study involving two groups of HF patients using different voice interface technologies (Amazon Alexa and a tablet-based avatar) over 90 days.
Patient engagement was quantified by the number of days technology was used, analyzed using multiple linear regression against demographic, clinical, and prior technology use data.

Main Results:

Older patients demonstrated higher engagement with voice interface telehealth (P=.004).
Increased number of HF medications was negatively associated with technology use (P=.005).
Black patients exhibited lower engagement compared to other racial groups (P=.08).

Conclusions:

Telehealth technologies are acceptable to older HF patients.
Higher disease burden (indicated by medication count) and lower engagement among Black patients necessitate further investigation and tailored technology development.
