Abstract

Background:Small-for-gestational-age (SGA) children have increased cardiovascular risk, but the mediating factors are poorly understood. We hypothesized that birth size could affect the cardiovascular system since childhood in the absence of other risk factors. We investigated endothelial and myocardial function in SGA children with regular catch-up growth.Methods and Results:Biochemical markers, blood pressure, flow-mediated vasodilation (FMD), common carotid intima-media thickness (cIMT), anteroposterior diameter of the infrarenal abdominal aorta (APAO) and echocardiographic parameters of left and right ventricular (LV and RV) function were studied in 27 SGA and 25 appropriate-for-gestational-age (AGA) subjects. SGA subjects had a higher homeostasis model assessment index than controls (2.61±1.27 vs. 1.56±0.40, P=0.01), higher cIMT (0.51±0.04 mm vs. 0.45±0.07 mm, P=0.007) and APAO (1.31±1.35 cm vs. 1.30±0.16 cm, P=0.005), and lower FMD (10.11±4.17% vs. 12.34±4.28, P=0.04) than controls. On echocardiography SGA had higher Tei index both at LV and RV than controls (P=0.001). Reduced RV systolic function was also observed in SGA subjects.Conclusions:SGA subjects had vascular morphological and function abnormalities compared with AGA, which increase their cardiovascular risk profile. Furthermore, a subtle cardiac alteration in both RV and LV functions was seen in SGA patients compared with AGA. (Circ J 2016; 80: 958–963)
