Insights

Cardiologists are aware of cognitive impairment (CI) in heart failure (HF) patients but rarely screen for it due to time constraints. Increased knowledge and support for routine screening correlate with higher screening frequency.

Area of Science:

  • Cardiology
  • Neurology
  • Healthcare Management

Background:

  • Cognitive impairment (CI) is prevalent in heart failure (HF) patients, negatively impacting adherence and outcomes.
  • Routine cognitive assessment in HF patients remains underutilized in clinical practice.

Purpose of the Study:

  • To assess current cognitive assessment practices among cardiologists managing HF patients.
  • To identify barriers to cognitive screening and evaluate associations between clinician knowledge, attitudes, and behaviors.
  • To explore the gap between awareness and implementation of CI screening in HF care.

Main Methods:

  • A cross-sectional survey was administered to 120 cardiologists within the Hellenic Heart Failure Clinics Network.
  • The survey included 13 questions on knowledge, attitudes, screening methods, and barriers related to CI in HF.
  • Data were analyzed using Pearson's chi-square to examine associations between variables.

Main Results:

  • A 42.5% response rate (51 cardiologists) was achieved, with 80% aware of CI prevalence but only 14% systematically screening.
  • Key barriers identified were lack of time (76%) and unfamiliarity with assessment tools (50%).
  • Significant positive correlations were found between CI knowledge and screening frequency, screening frequency and support for routine practice, and screening frequency and specialist referral.

Conclusions:

  • A significant gap exists between awareness of CI in HF patients and its systematic screening.
  • Clinician patient load did not influence screening frequency; time and tool familiarity are primary barriers.
  • Integrating screening tools and establishing clear referral pathways, coupled with education, can address the evidence-practice gap in CI management for HF patients.

Assessment of the Cardiovascular System I: Subjective Data

A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
Inquire about symptoms...

Acute Coronary Syndrome IV: Interprofessional Care

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...

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,...

Dementia

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual.
