Study Title | Assessment of metabolic changes in different animal models of maladaptive right ventricular hypertrophy in chronic pulmonary hypertension by lipidomics and HILIC |
Study Summary | We analyzed plasma samples from 33 Yucatan pigs belonging to four different experimental models of pulmonary hypertension (PH): M1 chronic postcapillary PH by pulmonary vein banding; M2 chronic PH by aorto-pulmonary shunting; M3: right ventricular pressure overload by pulmonary artery banding, thus without PH; and M0 sham procedure. Briefly, blood samples were collected 8 months after surgery and untargeted lipidomics and HILIC metabolomic analyses were performed for negative and positive polarities. For quality control, 5 QC samples were included in each analysis, iterative MSMS was performed for metabolite annotation. Plasma metabolomic patterns differed among groups, displaying arginine-nitric oxide and histidine deficiency in both PH models (M1 and M2), altered taurine and purine pathways in M2, and lipidomic changes in all three models of pressure overload. |

Treatment Summary: | Four different experimental models were generated: M1: a model of chronic postcapillary pulmonary hypertension by surgical nonrestrictive banding of the pulmonary veins; M2: a model of chronic pulmonary hypertension by aorto-pulmonary shunting; M3: a model of right ventricular pressure overload without pulmonary hypertension by pulmonary artery banding; and M0 a sham procedure. |
