Abstract:
Objective To assess the serum level of stromal-cell-derived factor 1 (SDF-1) in patients with congenital heart disease (CHD) and pulmonary arterial hypertension. Methods The heart color Doppler ultrasound was conducted to measure the tricuspid regurgitation velocity, in order to estimate pulmonary artery systolic pressure. According to the existing standards, a total of 86 patients were divided into CHD without pulmonary hypertension group (n=16), mild pulmonary hypertension group (n=18), moderate pulmonary hypertension group (n=17), severe pulmonary hypertension group (n=15). Another 20 healthy chil-dren were recruited as control group (n=20), The serum level of SDF-1 was detected by the ELISA method. Results The serum SDF-1 levels were signiifcantly lower in CHD groups than in control group (F=27.793, P<0.001). In CHD groups, CHD with se-vere pulmonary hypertension group had the lowest SDF-1 level, and CHD without pulmonary hypertension group had the highest SDF-1 level. There were signiifcant differences between CHD groups (P<0.05). The pulmonary artery systolic pressure was cor-related with serum SDF-1 levels (r=-0.737, P<0.001). Conclusions The serum level of SDF-1 is decreased in patients with CHD, and is negatively correlated with the severity of pulmonary arterial hypertension.
