Data are presented as mean±sd. P̄pa: mean pulmonary artery pressure; PVRi: indexed pulmonary vascular resistance; CI: cardiac index; Ppao: pulmonary artery occlusion pressure; RAP: right atrial pressure. #: no statistically significant differences were observed in baseline haemodynamics between responders and nonresponders; ¶: n = 4; +: n = 15.
