(a) Plasma levels and difference of MMP-7 in PH subgroups. MMP-7 levels in PAH were higher than in controls (p < 0.0001) but lower than in the other disease groups (p < 0.0081). (b) ROC curve of MMP-7 levels in PAH versus other groups. AUC: area under the curve; CTEPH: chronic thromboembolic PH; HFpEF-PH: PH due to HF with preserved EF; HFrEF-PH: PH due to HF with reduced EF; HF-NON-PH: HF without PH; MMP-7: matrix metalloproteinase-7, PAH: pulmonary arterial hypertension; ** indicates p value <0.01; ****indicates p-value < 0.0001.
