This study aims to explore the changes in endothelin-1 (ET-1), plasma neuropeptide Y, and calcitonin gene–related peptide (CGRP) in child patients before and after operation. A total of 80 child patients with congenital heart disease (CHD) complicated with pulmonary hypertension (PH) were enrolled and divided into control group (n = 40, conservative treatment for various reasons) and observation group (n = 40, active preoperative preparation and timely operative intervention) according to different treatments. There were positive correlations between systolic pulmonary arterial pressure (sPAP) and ET-1, plasma neuropeptide Y, while negative correlation between sPAP and CGRP. In conclusion, our data demonstrate that the levels of ET-1, plasma neuropeptide Y, and CGRP in PH-CHD were significantly changed after interventions, which provides new leads as alternative biomarkers to assess the efficacy of treatments against PH-CHD.
