Summary
Subjective cognitive concerns are common in heart failure (HF) patients, affecting up to 91%. These concerns correlate with HF severity, psychological distress, and impact quality of life, highlighting a need for targeted interventions.
Area of Science:
- Cardiology
- Neurology
- Psychology
Background:
- Cognitive dysfunction is a common issue for heart failure (HF) patients.
- Subjective cognitive concerns (SCC) are an individual's worries about their own cognitive abilities, which may differ from objective assessments.
- Little is known about the prevalence and impact of SCC in HF populations.
Purpose of the Study:
- To determine the prevalence and severity of SCC in patients with HF.
- To identify factors that influence SCC in HF patients.
- To explore the outcomes associated with SCC in HF.
Main Methods:
- An integrative literature review was performed using CINAHL, PubMed, PsycINFO, and EMBASE.
- Searches combined keywords related to heart failure and subjective cognitive concerns.
- Nine articles, comprising data from 567 individuals with HF, were included in the review.
Main Results:
- SCC prevalence in HF patients ranged from 40% to 91%, with mild to moderate severity.
- Factors influencing SCC included HF severity, psychological distress (depression, anxiety, stress), multimorbidity (COPD, insomnia, high BMI), and poorer objective cognitive function.
- SCC were linked to reduced quality of life, less engagement in meaningful activities, and increased self-care efforts.
Conclusions:
- Subjective cognitive concerns are highly prevalent and of mild to moderate severity in heart failure patients.
- Identifying factors that influence SCC can help pinpoint at-risk individuals.
- Understanding SCC outcomes can guide interventions to improve the health of HF patients.

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

3.8K
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...

01:27Heart Failure I: Introduction
903
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...

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 and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...
