Insights

Cardio Sem, a mobile app, helps heart failure patients monitor decompensation risk. Patients reported high acceptance, indicating its potential to improve self-care and symptom management.

Area of Science:

  • Cardiology
  • Health Informatics
  • Digital Health

Background:

  • Effective follow-up of heart failure patients with warning signs is crucial.
  • Timely help-seeking behavior and patient knowledge are key areas for improvement.
  • Technological integration offers opportunities to visualize decompensation risk.

Purpose of the Study:

  • To assess the acceptance of Cardio Sem, a mobile application designed for heart failure patients.
  • To evaluate the usability and perceived usefulness of a traffic light system for monitoring decompensation risk.

Main Methods:

  • A descriptive, observational pilot study involving 23 heart failure outpatients.
  • Participants used the Cardio Sem app daily for 4 weeks to visualize decompensation risk.
  • A technology acceptance questionnaire was administered post-intervention.

Main Results:

  • High acceptance rates for the Cardio Sem application were observed.
  • Perceived usefulness (100%), social influence (100%), and behavioral intent (99.8%) were particularly high.
  • The app facilitates early symptom detection and response to complications.

Conclusions:

  • Cardio Sem demonstrates significant patient acceptance and ease of use.
  • The application shows potential as a complementary tool for promoting heart failure self-care.
  • It can aid in the effective management of heart failure symptoms and complications.

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...

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 II: Pathophysiology

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...

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...
