Insights

Functional capacity and balance are key determinants of gait speed in heart failure with reduced ejection fraction (HFrEF). Improving these factors may enhance mobility and quality of life for HFrEF patients.

Area of Science:

  • Cardiology
  • Rehabilitation Medicine
  • Gerontology

Background:

  • Gait speed is a significant prognostic indicator in heart failure with reduced ejection fraction (HFrEF).
  • Limited evidence exists on the functional factors influencing gait speed in HFrEF patients.
  • Understanding these determinants is crucial for targeted interventions.

Purpose of the Study:

  • To investigate the functional determinants of gait speed in patients diagnosed with HFrEF.
  • To identify key factors that influence walking speed in this population.

Main Methods:

  • A cross-sectional study involving 59 HFrEF patients.
  • Gait speed measured via a 4-meter walk test.
  • Functional capacity assessed using the 6-minute walk test (6MWT), and balance evaluated with the Berg Balance Scale (BBS).
  • Dyspnea, functional mobility, and physical activity were also measured.

Main Results:

  • Gait speed showed significant correlations with age, NYHA class, mMRC score, 6MWT, 5-STS test, BBS, and IPAQ scores.
  • The 6-minute walk test (6MWT) distance and Berg Balance Scale (BBS) emerged as independent determinants of usual gait speed.
  • These two factors explained 44.4% of the variance in gait speed.

Conclusions:

  • Functional capacity and balance are independent predictors of gait speed in HFrEF patients.
  • Interventions targeting functional capacity and balance may improve gait speed and outcomes in HFrEF.

Pathophysiology of Heart Failure01:17

Pathophysiology of Heart Failure

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 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...

Factors Influencing Heart Rate01:30

Factors Influencing Heart Rate

The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...

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 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,...
