Background: Cardiovascular disease accounts for significant morbidity and mortality in chronic obstructive pulmonary disease. The present study was conducted to assess association between echocardiographic findings in COPD patients and its severity. Materials & Methods: 86 COPD patients of both genderswere diagnosed clinically as having COPD with confirmation by spirometry.Pulmonary function tests were done in all patients and they were graded according to the severity of COPD with guidelines given by Global initiative for Obstructive Lung Disease (GOLD). Chest x-ray, twelve lead electrocardiogram, and 2-D Echo were done to evaluate the severity of RV dysfunction. Results: Out of 86 patients, males were 56 and females were 30. Symptoms were breathlessness in 70, cough with sputum in 54, fever in 48, swelling of feet in 32 and decreased urinary output in 15. Signs were raised JVP in 62, tachypnea in 56, Loud P2 in 43, ascites in 17, pedal edema in 21 and cyanosis in 30 cases. The difference was significant (P< 0.05). ECG findings were Cor pulmonale (42), LVDD (30), RVH (21), PAH (18), RA/RV dilatation (15), RVSD (12) and LVH (10). There was significant association between echocardiographic findings with severity of COPD (P< 0.05). Conclusion: High occurrence of cardiac co morbidities such as PAH, RV dysfunction and LV dysfunction accompanied COPD patients.
