Results

sVEGF-A165b has the potential to detect LD-PH among the etiologies of PH, and sES may detect CTD-PAH in PAH. In addition, sES may be a marker to estimate the severity of PH. Because sES was correlated with the main items of the ESC risk table, sES is thought to reflect the severity of PH in recent treatment strategies. Further studies are needed in a treatment-naive cohort to verify the usefulness of sES.

Baseline Characteristics

Of the 107 PH patients, 48 (44.9%) were in Group 1, 5 (4.7%) were in Group 2, 4 (3.7%) were in Group 3, and 50 (46.7%) were in Group 4. There were significant differences among the groups in terms of age, sex, and plasma hemoglobin concentrations; 85% and 58% of patients in Groups 1 and 4, respectively, were female. Hemoglobin levels were significantly higher in Group 3 than in the other groups. With regard to hemodynamics, there were significant differences among the groups in diastolic pulmonary pressure (dPAP), cardiac index (CI), mean right pressure (mRAP), and PAWP. dPAP and CI were significantly higher in Group 1, and mRAP was significantly lower in Group 3. There were no significant differences in the other indicators among the groups.
