| Outline of Final Research Achievements |
Presence of pericardial effusion, an average mean right atrial pressure of >=10mmHg, or cardiac index <2.5 L/min/m2 were associated with mortality among 81 consecutive patients diagnosed with group 1 or 1′ PH,. Left ventricular (LV) end-systolic volume index was significantly associated with mortality among 31 non-ischemic dilated cardiomyopathy (DCM) patients with PH (Group 2). The peak PETCO2 obtained by cardiopulmonary exercise testing (CPX) could provide useful prognostic markers for 12 patients with CTEPH (Group 4), but not 17 group 1 PH patients treatment with bosentan therapy. The peak PETCO2 may become a marker for estimating the degree of restored pulmonary vascular bed in group 4 PH (CTEPH).
In some PH patients, serum vascular endothelial growth factor (VEGF)165b, an inhibitory VEGF splice variant, was elevated. Study to investigate the relationship between VEGF165b and mean pulmonary arterial pressure, pulmonary vascular resistance, or cardiac index is underway.
