ABSTRACT

Background: Chronic Obstructive Pulmonary Disease (COPD) is the fourth leading cause of death, and by 2020, it is expected to rise to the 3rd  position as a cause of death. Pulmonary hypertension is a serious complication of COPD and is associated with poor prognosis. Thus, early detection and treatment of pulmonary hypertension becomes important to prevent right heart failure.

Aim: The present study was undertaken to study the prevalence of pulmonary hypertension in COPD patients and to highlight the importance of early diagnosis of pulmonary hypertension to prevent further complications.

Materials and Methods: 130 patients,who presented with history of cough, sputum, breathlessness or wheezing of more than 3 months duration to the department of Pulmonology, Chalmeda Anand Rao Hospital were subjected to pre and post-bronchodilator pulmonary function testing. During 01st November 2012 to 30th June 2014. Those patients whose post-bronchodilator FEV1/FVC was less than 0.7 were included in this study. These patients were evaluated for presence of pulmonary hypertension using chest X-ray, electrocardiogram, 2D echocardiography.

Results: Out of 130 cases diagnosed with COPD, 122 patients were included in the study and 8 cases were excluded of which 2 cases were  excluded due to coexisting cardiac disease and 6 cases were excluded due to poor window at 2D-Echocardiography. Our study showed that PFT parameters R/S ratio in V6  in ECG  showed inverse correlation to severity of COPD, cardiomegaly in chest x-ray was more prominent in severe COPD.

Conclusion: This study focuses on non invasive methods like ECG , X-ray, 2D Echo and PFT in screening for pulmonary hypertension and subsequent development of cor pulmonale in COPD patients.

KEY WORDS: COPD, Pulmonary hypertension, 2D Echo, ECG, Chest x-ray.
