96 [651/001] Echocardiographic diastolic dysfunction parameters are predictors of pulmonary hypertension in cardiac failure. J. Saavedra, R. Dalrnau, M.A. Gornez, M. Pornbo, C. Gornez, V. Sanchez, F: Lornbera, J. Garcia, M . 1 Velazquez, C. Saenz (Madrid, ES) Pulmonary hypertension (PHT) in patients with left ventricular systolic dysfunction (LVSD) is associated to a worse prognosis. We have studied the prevalence of PHT in a group of patients with LVSD and its relation to echocardiographic parameters of diastolic function (DF). We have studied a series of 36 patients, 27 men, medium age Will years with LVSD, mean ejection fraction (EF) 24.4i7.3%. 16 of them had coronary disease and 20 had dilated cardiomyopathy. A transthoracic echocardiography was performed measuring: the systolic pulmonary arterial pressure (SPAP), DF parameters in the mitral flow, E and Avelocity, WA ratio, E deceleration time(EDT) and isovolumetric relaxation time (IVRT), and in the right superior pulmonary vein: systolic wave velocity (S), diastolic (D) their areas (ARS and ARD) and their ratio (S/D) and the velocity of the atrial retrograde wave (A). The systolic fraction (SF) was calculated as the ratio between ARS and the sum of ARS plus ARD. SPAP could be measured in 27 of 36 patients (75%). 59% (16) had a SPAP over 30 mmHg. The mean SPAP was 37.2i14.7 mmHg. Correlation between SPAP and DF parameters are described in the table below. PARAMETER MEDIA S.D.
