title: Echocardiographic evaluation of left ventricular diastolic function in chronic cor pulmonale.
abstract: In this study we hoped to understand the abnormalities of left ventricular filling dynamics in chronic cor pulmonale. Our findings showed a severe left ventricular diastolic impairment, directly related to a progressive increase in pulmonary hypertension itself, as expressed by correlation analysis between systolic pulmonary artery pressure and the following parameters: transmitral flow velocity in early/late diastole ratio (r = -0.69, p <0.001), isovolumic relaxation time (r = 0.54, p = 0.001), and transmitral flow velocity in early diastole (r = -0.59, p <0.01).
