Introduction: Chronic obstructive pulmonary disease (COPD) affects __ampersandsigngt; 5% of the population. COPD and congestive heart failure (CHF) frequently coexists and ventricular function has important role in mortality and morbidity among COPD patients. Objectives: Aim of our study was to correlate left and right ventricular function by echocardiography, to correlate it with pulmonary function test (PFT), with age and sex matched control. Materials: Through clinical examination, chest x ray, pulmonary function test, ECG, echocardiography(2D, M mode, Doppler) were done in each cases and controls. Results: Left ventricular, right ventricular, left atrial dimensions were increased compared to control population. Right ventricular end diastolic dimension (RVEDd) and left ventricular end diastolic dimension (LVEDd) ratio is increased in COPD group. E/Ea ratio, PVS, PVD pattern, S/D ratio are altered significantly. RVEF (right ventricular ejection fraction) and TAPSE(tricuspid annular plane systolic excursion) decreased. Conclusion: Echocardiography is an easy and available investigation in clinical practice. To correlate cardiac function abnormality and COPD severity is important for prognostic significance.
