Background: COPD is characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways and the lung to noxious particles or gases. It leads to cor pulmonale causing right ventricular failure. Present study compares the serum level of CA-125 and 2 D Echo for detection of right ventricular failure in COPD patients.

Methods: In this study 178 patients suffering from COPD has been taken after following inclusion and exclusion criteria and informed consent. Serum CA 125 levels are evaluated in all patients and compared with the right ventricular functions.

Results: The mean CA125 was higher in subjects with RV failure (96.32) as compared to those subjects with RV normal (37.17). The result was statistically significant. (p<0.001). The mean duration of illness was higher in subjects with raised CA125 (8.71 years) as compared to those with normal CA 125 (6.67 years) and the difference was also statistically significant (P<0.001).

Conclusions: CA-125 levels have a good sensitivity and specificity for predicting right ventricular failure in COPD patients. Diagnostic accuracy, high positive and negative predictive value makes CA-125 a good predictor of right ventricular failure in COPD patients.
