The major causes of PAH are right heart failure caused by congenital heart disease with left-right shunt, ARDS, neonatal persistent pulmonary hypertension, collagen disease, pulmonary fibrosis, idiopathic pulmonary arterial hypertension, etc. Inhibitory effects of KNO3 was investigated in pulmonary arteries of chronic hypoxia-induced hypertension rats. Mean pulmonary arterial pressure and right ventricular hyperttrophy were significantly increased by hypoxic exposure, resulting in hypoxic-induced pulmonary hypertension model. Result such as mean pulmonary arterial pressure (mPA), mean pulmonary arterial pressure / mean artirial blood pressure (mPA/mAp), and right ventricular hypertrophy (RVH) were significantly increased by chronic hypoxia-induced hypertension, but inhibition of KNO3 was not observed. Suppressive effect of KNO3 that were not obtained on chronic hypoxia-induced pulmonary hypertension should be further examined., 2016年度~2018年度科学研究費補助金(基盤研究(C))研究成果報告書, 16K10933}, title = {実験的肺高血圧に対する亜硝酸依存性NO合成機構の賦活による治療}, year = {2019} }
