Echocardiographic characteristics.

<p>Non-survivors vs. survivors <i>P</i><0.05 indicated significantly different. LV: left ventricle; RV: right ventricle; LA: left atrium; RA: right atrium; IVS: interventricular septum; LVMI: LV mass indexed to body surface area; EF: ejection fraction; MAPSE: average of mitral annular plane systolic excursion measured at the septal and lateral sites; TAPSE: tricuspid annular plane systolic excursion; E: early diastolic peak filling velocity; A: late diastolic peak filling velocity; E′: tissue Doppler early diastolic septal mitral annular velocity. DT: deceleration time of early diastolic peak velocity; IVRT: isovolumic relaxation time; SPAP: systolic pulmonary artery pressure.</p><p>Echocardiographic characteristics.
