LCN2 and pulmonary arterial hypertension: Multi-variate logistic regression identified independent predictors of CHD-PAH.<h4>Results</h4>Plasma LCN2 (135.1 [40.2] vs 67.7 [17.7] ng/ml; P < .05) and relative miR-8078 expression (4.2 ± 1.1 vs 2.3 ± 1.3 fold; P < .05) were significantly elevated in the moderate-to-severe PAH group compared with the non-PAH group.
