Summary
Acute exacerbations of chronic obstructive pulmonary disease (COPD) negatively impact right ventricular (RV) function. Tissue Doppler imaging (TDI) parameters like isovolumic myocardial acceleration (IVA) and tricuspid annulus peak systolic velocity (Sa) can detect subclinical RV dysfunction during COPD exacerbations.
Area of Science:
- Cardiology
- Pulmonology
- Medical Imaging
Background:
- Chronic obstructive pulmonary disease (COPD) can lead to impaired right ventricular (RV) function.
- Tissue Doppler imaging (TDI) is a valuable noninvasive tool for assessing RV longitudinal function.
Purpose of the Study:
- To evaluate the effect of acute COPD exacerbation on RV function.
- To assess RV function using TDI parameters.
Main Methods:
- The study included 30 COPD patients experiencing acute exacerbation and 30 controls.
- RV function was assessed using echocardiography, including tricuspid annular plane systolic excursion, tricuspid annulus peak systolic velocity (Sa), and TDI-derived isovolumic myocardial acceleration (IVA).
- Assessments were performed during exacerbation and after recovery.
Main Results:
- COPD patients during exacerbation showed larger RV size, higher pulmonary artery systolic pressure, and lower IVA, Sa, and tricuspid annular plane systolic excursion compared to controls.
- After recovery, RV size and pulmonary artery systolic pressure decreased, while IVA and Sa increased to control levels.
- Significant correlations were found between TDI parameters and RV function indicators.
Conclusions:
- Acute COPD exacerbations adversely affect RV function.
- TDI-derived IVA and Sa are useful for detecting subclinical RV dysfunction in COPD patients during exacerbations.

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 (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

4.2K
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.

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
