Chronic Obstructive Pulmonary Disease01:22

Chronic Obstructive Pulmonary Disease

2.3K
COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Chronic Obstructive Pulmonary Disease-I: Introduction

Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

Summary

Handgrip strength (HGS) is significantly lower in patients with chronic obstructive pulmonary disease (COPD) exacerbation compared to stable COPD. HGS may serve as a key indicator of muscle performance in COPD exacerbation.

Area of Science:

  • Pulmonary Medicine
  • Respiratory Physiology
  • Clinical Nutrition

Background:

  • Chronic obstructive pulmonary disease (COPD) is characterized by reduced respiratory and peripheral muscle strength.
  • Handgrip strength (HGS) is a recognized indicator of overall muscle strength and extremity muscle function.
  • Investigating factors affecting HGS in COPD exacerbation is crucial for understanding disease impact.

Purpose of the Study:

  • To measure handgrip strength (HGS) in patients experiencing COPD exacerbation.
  • To identify factors associated with HGS in COPD patients during exacerbation.
  • To explore the utility of HGS as a functional measure in COPD exacerbation.

Main Methods:

  • A comparative study involving patients with COPD exacerbation (n=101), stable COPD (n=22), and controls (n=201).
  • Handgrip strength (HGS) measured using a Vigorimeter.
  • Pulmonary function tests and 6-minute walk tests (6MWD) conducted.

Main Results:

  • Mean HGS was significantly lower in COPD exacerbation patients compared to stable COPD and control groups.
  • Mean HGS was similar between stable COPD and control groups.
  • A moderate correlation was observed between HGS and 6MWD in COPD exacerbation patients, but not with pulmonary function tests.

Conclusions:

  • Reduced HGS in COPD exacerbation is not explained by age, comorbidities, obstruction severity, or smoking.
  • Physical inactivity and steroid use may contribute to decreased HGS during exacerbation.
  • HGS can be a valuable measure of muscle performance in COPD exacerbation, particularly when 6MWD is not feasible.
