Clinical data was grouped according median value of TAPSE/PASP (0.43 mm/mmHg) for the studied population.
Data are presented as mean ± standard deviation.
E/E′: early diastolic transmitral flow velocity to averaged annular early diastolic velocity ratio, LA: left atrial, LVEDD: LV end-diastolic diameter, LVEF: left ventricular ejection fraction, LVESD: LV end-systolic diameter, PASP: pulmonary systolic artery pressure, RA: right atria, RV: right ventricle, RVEDA: RV end-diastolic area, RVESA: RV end-systolic area, RVFAC: right ventricular fractional area change, S′: tricuspid annular systolic velocity, TAPSE: tricuspid annular plane systolic excursion.
Statistical significance between groups was calculated using Student's t-test. A p value < 0.05 was considered significant.
