Insights

Cognitive function and health literacy are independently linked to heart failure (HF) knowledge. Interventions targeting both improved understanding and self-management in HF patients.

Area of Science:

  • Cardiology
  • Health Literacy Research
  • Cognitive Science

Background:

  • Heart failure (HF) management is complex and requires significant patient understanding.
  • Cognitive function and health literacy are potential key factors influencing HF self-management.
  • Understanding these factors is crucial for improving patient outcomes in heart failure.

Purpose of the Study:

  • To determine the relationship between cognitive function and health literacy in relation to heart failure knowledge.
  • To investigate how these factors independently influence a patient's understanding of their condition.

Main Methods:

  • 330 outpatients with heart failure (HF) were assessed.
  • Health literacy was measured using the Medical Term Recognition Test and Rapid Estimate of Adult Literacy in Medicine.
  • Cognitive function was screened using the Modified Mini-Mental Status Examination, and HF knowledge was assessed via the Dutch Heart Failure Knowledge Scale (DHFKS).

Main Results:

  • Both health literacy (β = .26, p < .001) and cognitive function (β = .36, p < .001) were significantly related to HF knowledge (DHFKS scores).
  • These associations remained significant when considered independently (health literacy: β = .13, p = .044; cognition: β = .30, p < .001).

Conclusions:

  • Impaired health literacy and cognitive function are independently associated with reduced heart failure knowledge.
  • Interventions aimed at improving heart failure knowledge should address both health literacy and cognitive function for maximum effectiveness.
  • Targeting these dual factors can enhance patient self-management and potentially improve outcomes in heart failure care.

Health Literacy01:21

Health Literacy

Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative...

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 I: Introduction01:27

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 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...

Pathophysiology of Heart Failure01:17

Pathophysiology 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...

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...
