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 programs,...

Imaging Studies for Cardiovascular System I:Echocardiography

Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion, evaluates...

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Cardiomyopathy V: Interprofessional Care

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...
Cardiomyopathy VII: Pre and Post Operative Nursing Management01:28

Cardiomyopathy VII: Pre and Post Operative Nursing Management

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Area of Science:

  • Digital Health
  • Cardiology
  • Health Literacy

Background:

  • Digital health solutions are crucial for healthcare but require patient digital health literacy for safe use.
  • Disparities in digital health literacy can limit access to beneficial digital services for cardiac patients, especially those undergoing surgery.
  • Denmark's advanced digital health system offers a unique setting to study digital health literacy in this population.

Purpose of the Study:

  • To assess digital health literacy in patients scheduled for elective open-heart surgery.
  • To examine the associations between digital health literacy and sociodemographic factors and concurrent health issues.

Main Methods:

  • A cross-sectional survey was conducted with patients undergoing elective open-heart surgery across three Danish university hospitals.
  • Digital health literacy was measured using the eHealth Literacy Scale (eHEALS), alongside questions on perceived importance and usefulness of online health information.
  • Sociodemographic data and concurrent health issues were collected; analyses examined associations with eHEALS scores and subdomains.

Main Results:

  • 313 out of 576 eligible patients completed the survey (54.3% response rate).
  • Median eHEALS scores were high (30/40), indicating generally good digital health literacy.
  • Scores were negatively correlated with age and positively associated with educational level; confidence in evaluating online health information quality was lowest.

Conclusions:

  • Patients undergoing elective open-heart surgery generally exhibit high digital health literacy.
  • Challenges persist in critically appraising digital health information, suggesting a need for targeted support.
  • Individual assessments are recommended to identify patients requiring tailored digital health literacy support.
