Background And Aims:
Chronic obstructive pulmonary disease (COPD) patients with right ventricular (RV) dysfunction have poor prognoses, and early detection of RV dysfunction is beneficial. Therefore, we aimed to determine the association between CA125 levels and RV dysfunction in patients with COPD.
Methods:
We enrolled 40 patients with stable COPD underwent echocardiography and the serum CA125 levels were measured.
Results:
The mean CA125 level was higher in COPD patients with RV dysfunction (17.28 ± 27.35 U/mL) than without (10.94 ± 10.62 U/mL); however, it was not statistically significant (p = 0.147). Additionally, tricuspid annular plane systolic excursion and pulmonary arterial pressure were not significantly different, while RV free wall strain (RVFWS) was decreased in the COPD patients with RV dysfunction when compared to the patients without RV dysfunction (p < 0.001). Moreover, the CA125 level was remarkably correlated with RVFWS (r = -0.497, p = 0.03) and FAC (r = 0.51, p = 0.025) in patients with RV dysfunction.
Conclusion:
We found that the CA125 level may not be beneficial in detecting RV dysfunction in stable COPD patients without exacerbation or hospitalization. However, further examinations with larger sample sizes are necessary to confirm our findings.

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.

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...
