  1. Values expressed as mean ± SD. Definition of abbreviations: SScPAH+: systemic sclerosis-associated pulmonary arterial hypertension; SScPAH-: SSc without PAH. mPra: mean right atrial pressure; Ppa: pulmonary artery pressure; PVR: pulmonary vascular resistance; CI: cardiac index; PCWP: pulmonary capillary wedge pressure.* p < 0.05 for comparison of SScPAH+ with SScPAH-;
