Abstract: Background and Objective: The objective of the study was to know the clinical profile, radiological features, electrocardiographic and echocardiographic changes in chronic cor pulmonale. Methodology: This was a hospital based longitudinal study carried out among cases admitted in medical wards of Karnataka Institute of Medical Sciences, Hubli during December 2011 to November 2012. Inclusion criteria were confirmed cases of chronic cor pulmonale with history of cough with sputum, paroxysmal cough, dyspnea, fluid retention with edema and sometimes ascites, recurrent chest infections, cyanosis, fatigue, chest pain, near syncope, palpitation. Results: About 50 cases were included in the study, 31 were males and 19 were females. The peak incidence of chronic cor pulmonale was found to be in the middle and older age groups Chronic cor pulmonale patients were admitted more commonly in the winter months of the year. Smoking was found to be an important factor in precipitating or aggravating the primary lung disease and hence cor pulmonale. Most of the cases had chronic bronchitis with or without emphysema. 70% of the patients showed chest x- ray suggestive of chronic bronchitis with or without emphysema. 38% showed evidence of cardiomegaly with or without signs of pulmonary hypertension. Electrocardiogram showed changes from normal to right ventricular hypertrophy. The present study showed 22% cases with RVH (Right Ventricle Hypertrophy), 62% RAD(Right Axis Deviation), 30% RBBB(Right Bundle Branch Block) and 52% with P pulmonale. Conclusion: In the present study most of the patients showed clear evidence of features suggesting chronic cor pulmonale on 2D-ECHO. Thus, ECHO was a better diagnostic tool when compared to ECG in the present study.
