Data are presented as mean±sd or n (%) unless otherwise stated
BPs: systolic blood pressure
fc: cardiac frequency

RV/LV: right-to-left ventricle diameter ratio
TVPG: tricuspid valve pressure gradient
SAE: at least one in-hospital serious adverse event (death, cardiopulmonary resuscitation, thrombolysis, need for i.v. catecholamine infusion)
