Infants with FGR (n = 1020) and SGA (n = 2328) were compared to infants born appropriate for gestational age using linear regression with adjustment for body size, age at examination, sex, and gestational age at birth. FGR and SGA were associated with reduced left ventricular (LV) internal diameters in end-systole [adjusted mean difference (aMD) \u22120.09\u2005mm, 95% confidence interval (CI) \u22120.18,0.01, and \u22120.12\u2005mm, 95% CI \u22120.19, \u22120.06, respectively] and end-diastole (aMD \u22120.13\u2005mm, 95% CI \u22120.24, \u22120.02, and \u22120.15\u2005mm, 95% CI \u22120.22, \u22120.07, respectively). Exposed newborns also had thinner LV walls [interventricular septum, end-diastole: FGR \u22120.07\u2005mm (95% CI: \u22120.11, \u22120.03), SGA \u22120.03\u2005mm (95% CI \u22120.06, \u22120.01); LV posterior wall, end-diastole: FGR \u22120.05\u2005mm (95% CI \u22120.09, \u22120.01), SGA \u22120.04\u2005mm (95% CI \u22120.07, \u22120.01)]. Both groups exhibited changes in trans-mitral flow. FGR was associated with reduced right ventricular function (TAPSE aMD \u22120.20, 95% CI \u22120.31, \u22120.09), whereas SGA was associated with reduced LV end-diastolic (aMD \u22120.16, 95% CI \u22120.28, \u22120.04) and end-systolic volumes (aMD \u22120.08, 95% CI \u22120.13, \u22120.02) and alterations in electrocardiogram precordial leads.
