Pulmonary hypertension (PH) is associated with hypoxic exposure, enhanced production of reactive oxygen species (ROS) and proliferation of vascular smooth muscle cells (VSMC). In this study, we tested our hypothesis that cyclophilin A (CyPA) contributes to pulmonary vascular remodeling in patients with PH. Plasma CyPA levels were significantly elevated in patients with PH than in those without PH or healthy controls. Moreover, plasma CyPA levels increased according to the quartiles of pulmonary vascular resistance. Medical treatments reduced plasma CyPA levels in patients with PH. Finally, event-free curve revealed that high plasma CyPA predicted poor outcome (death or lungtransplantation). These results indicate that plasma CyPA is a novel biomarker for patients with PH.

肺动脉高压（pH）与低氧暴露，活性氧（ROS）的产生增强以及血管平滑肌细胞的增殖（VSMC）有关。在这项研究中，我们检验了我们的假设，即环磷脂A（CYPA）有助于pH患者有助于肺血管重塑。与没有pH或健康对照的患者相比，pH患者的血浆CYPA水平显着升高。此外，根据肺血管抗性的四分位数，血浆CYPA水平升高。医疗治疗降低了pH患者的血浆CYPA水平。最后，无事件的曲线显示，高血浆CYPA预测结果不佳（死亡或肺部植入）。这些结果表明，血浆CYPA是pH患者的新型生物标志物。
