Pulmonary arterial hypertension (PAH) remains a disease with limited therapeutic options and dismal prognosis. Despite its etiologic heterogeneity, the underlying unifying pathophysiology is characterized by increased vascular tone and adverse remodeling of the pulmonary circulation. Myeloperoxidase (MPO), an enzyme abundantly expressed in neutrophils, has potent vasoconstrictive and profibrotic properties, thus qualifying as a potential contributor to this disease. Here, we sought to investigate whether MPO is causally linked to the pathophysiology of PAH. Investigation of 2 independent clinical cohorts revealed that MPO plasma levels were elevated in subjects with PAH and predicted adverse outcome. Experimental analyses showed that, upon hypoxia, right ventricular pressure was less increased in Mpo-/- than in WT mice. The hypoxia-induced activation of the Rho-kinase pathway, a critical subcellular signaling pathway yielding vasoconstriction and structural vascular remodeling, was blunted in Mpo-/- mice. Mice subjected to i.v. infusion of MPO revealed activation of Rho-kinase and increased right ventricular pressure, which was prevented by coinfusion of the Rho-kinase inhibitor Y-27632. In the Sugen5416/hypoxia rat model, PAH was attenuated by the MPO inhibitor AZM198. The current data demonstrate a tight mechanistic link between MPO, the activation of Rho-kinase, and adverse pulmonary vascular function, thus pointing toward a potentially novel avenue of treatment.

Background and Purpose- Mobile stroke units (MSUs) are known to increase the proportion of acute ischemic stroke (AIS) patients treated with intravenous thrombolysis (IVT) in the first golden hour (GH) after onset compared with hospital settings (HS). However, because of the low number of AIS patients treated with intravenous thrombolysis within this ultraearly time window in conventional care, characteristics, and outcome of this subgroup of AIS patients have not been compared between MSU and HS. Methods- MSU-GH patients were selected from the Berlin-based MSU (STEMO [Stroke Emergency Mobile]), whereas HS-GH patients were selected from the SITS-EAST (Safe Implementation of Treatments in Stroke-East) registry. The outcome events of interest included the rates of favorable functional outcome (modified Rankin Scale scores of 0 or 1), distribution of the modified Rankin Scale scores, and mortality after 3 months between MSU-GH and HS-GH groups. Results- We identified 117 MSU-GH (38.4% of 305 MSU-treated patients) and 136 HS-GH (0.9% of 15 591 HS-treated patients) eligible patients without prestroke disability. No significant differences were documented in the rates of favorable functional outcome (51.3% versus 46.2%, P=0.487) and mortality (7.7% versus 9.9%, P=0.576) at 3 months, or in the distribution of 3-month modified Rankin Scale scores between the 2 groups ( P=0.196). In multivariable logistic regression analyses, adjusting for potential confounders, MSU treatment was not associated with a significantly different likelihood of favorable functional outcome (odds ratio, 1.84 for MSU patients; 95% CI, 0.86-3.96) or mortality (odds ratio, 0.95; 95% CI, 0.28-3.20) at 3 months. Conclusions- There is no evidence that safety and efficacy of ultraearly intravenous thrombolysis for AIS differs when used in MSUs or in HS.
