Echocardiographic Evaluation of Right Ventricular Function and its Role in the Prognosis of Chronic Obstructive Pulmonary Disease.

ABSTRACT:

Background

Chronic obstructive pulmonary disease (COPD) is associated with structural and mechanical changes in the pulmonary vascular bed that increase right ventricular (RV) afterload and subsequently right heart failure.

Objectives

The aim of the study was to elucidate RV dysfunction at rest by echocardiography in a cohort of COPD patients and to study its impact on prognosis.

Methods

84 patients of COPD and 40 matching healthy controls were evaluated at baseline. Evaluation included clinical examination, pulmonary function tests; 6 minutes walk test and echocardiography. Patient with COPD were again evaluated after 6 months.

Results

All echocardiographic parameters of RV function were significantly impaired in COPD patients as compared to controls. Clinical
