Abstract
Aim of the work
The aim of this study is to evaluate both left and right ventricular diastolic function in a group of patients with COPD with or without pulmonary hypertension to answer the question of the cause of deterioration in such group of patient.
Conclusions
Doppler echocardiography is a simple non invasive tool for evaluation of global and regional cardiac functions.
In patients with COPD and pulmonary hypertension right ventricular systolic and diastolic dysfunction was present. Systolic dysfunction represented by decrease RVFS and RVEF, and diastolic dysfunction represented by increase the tricuspid A velocity and decrease tricuspid E/A ratio. The global function of the right ventricle was impaired, and this represented by increase in right ventricular Tie index.
Also left ventricular diastolic dysfunction was present and represented by prolongation of IVRT, which is more sensitive than mitral E/A ratio due to age related changes that occur in the later.
The global left ventricular function was impaired represented by increase in the left ventricular Tie index.
Left ventricular dysfunction was contributing to the functional deterioration in such patients.
