Echocardiography and pulmonary artery pressure: correlation in chronic obstructive pulmonary disease.

The aim of this study was to assess whether 2 dimensional echocardiography can provide reliable parameters to quantitatively estimate pulmonary hypertension (PH) in patients with chronic obstructive pulmonary disease. Twenty subjects, 16 males and 4 females, mean age 54.5 year +/- 4.92 were evaluated. Right ventricular dimensions were measured using subcostal 2- dimensional (2D) approach viz. right ventricular maximum short axis (Rv) and tricuspid annulus (TA). Free right ventricular anterior wall (AW) was measured by M-Mode. A 2D Index was calculated RV x TA + Aw and the same correlated with mean pulmonary artery pressure (r = 0.97). This appears to be a useful non-invasive method foe estimating PH in cases of COPD.
