Heart Failure VII: Nursing Interventions01:30

Heart Failure VII: Nursing Interventions

379
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,...

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...

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.

Pathophysiology of Heart Failure01:17

Pathophysiology of Heart Failure

2.6K
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 Drugs: β-Blockers01:22

Heart Failure Drugs: β-Blockers

710
β-adrenergic antagonists, commonly known as β-blockers, block the effects of sympathetic neurotransmitters such as noradrenaline (NA) and adrenaline (ADR). They have several beneficial effects in heart failure treatment. They reduce heart rate, the force of contraction, and cardiac muscle relaxation. They also slow the atrial-ventricular conduction rate and raise the threshold for arrhythmias. The concentration of β-blockers determines their effects on bronchodilation,...

Heart Failure IV: Classification and Diagnostic Evaluation

264
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...

Summary
This summary is machine-generated.

Many heart failure patients lack awareness of guideline-directed medical therapy (GDMT), especially newer drugs. Patient education and shared decision-making are crucial for improving GDMT use in heart failure care.

Area of Science:

  • Cardiology
  • Patient-Reported Outcomes
  • Pharmacotherapy

Background:

  • Guideline-directed medical therapy (GDMT) significantly improves outcomes for patients with heart failure (HF).
  • However, substantial gaps exist in the utilization of GDMT in clinical practice.
  • Patient perspectives on GDMT, including their goals and preferences, are largely unaddressed.

Purpose of the Study:

  • To survey patients with chronic heart failure (HF) to understand their experiences.
  • To assess patient familiarity and concerns regarding guideline-directed medical therapy (GDMT) for HF.
  • To identify barriers to GDMT uptake from the patient's viewpoint.

Main Methods:

  • A survey was administered to a representative sample of US adults with a diagnosis of HF and currently on HF medications.
  • The survey explored disease-related goals, challenges of living with HF, medication decision-making, and awareness/concerns about HF therapies.
  • Data were collected from 429 participants via the GfK KnowledgePanel between October and November 2018.

Main Results:

  • Most surveyed patients were familiar with older HF medications like beta-blockers and diuretics.
  • Familiarity was notably lower for newer therapies, including angiotensin receptor-neprilysin inhibitors (24.9%) and mineralocorticoid receptor antagonists (24.9%).
  • Significant proportions of patients expressed concerns about the safety (up to 42.5%) and effectiveness (up to 41%) of various GDMT classes.

Conclusions:

  • A considerable number of heart failure patients demonstrate limited familiarity with guideline-directed medical therapy (GDMT).
  • Lack of familiarity correlates with concerns regarding the safety and efficacy of these essential HF treatments.
  • Improving patient education and implementing shared decision-making strategies are vital for enhancing GDMT adoption in heart failure management.
