Aim and objective: To estimate the two-dimensional echocardiographic study of left ventricular volume and function in chronic obstructive pulmonary disease (COPD) patients admitted in tertiary care hospital.
Introduction: COPD affects pulmonary blood vessels, right ventricle, as well as left ventricle leading to the development of pulmonary hypertension (PH), cor pulmonale (COR-P), right and left ventricular dysfunction. The present study was conducted to determine the relation between severity of airway obstruction (stages) of COPD and left ventricular dysfunction. Secondary objective was to assess the correlation between smoking and left ventricular (LV) dysfunction.
Materials and methods: A cross-sectional descriptive study was conducted in the tertiary Medical College and Hospital. A total of 52 COPD patients were included by convenience sampling into the study. The echo study addressed pericardial condition, cardiac dimensions, LV systolic and diastolic function, and hemodynamic of pulmonary circulation. LV dysfunction was outcome variable and IBM SPSS version 22 were used for statistical analysis.
Results: Majority of the participants were aged between 61 and 70 years. LV diastolic dysfunction was observed in eight (15%) participants and LV systolic dysfunction was observed in five (10%) participants. The mean E/A ratio significantly decreased as the severity of COPD increased (p = 0.024). A weak negative correlation was observed between duration of smoking and E/A ratio and left ventricular end diastolic diameter.
Conclusion: LV defects, specifically E/A ratio was inversely proportional to the severity of the COPD.
