(A) RV FW longitudinal strain (RV FWLS%): In all infants RV FWLS % increased from Day 5–7 to one year CA (p < 0.01). RV FWLS % was higher and tracked superior in the uncomplicated preterm infants (blue circles with blue solid line) when compared to the preterm infants who developed BPD (red squares, dotted red lines) on echocardiogram at the time of evaluation. (B) Interventricular septal (IVS) global longitudinal strain (GLS, %): In all infants IVS GLS increased from 32 weeks PMA to one year CA (p < 0.01). IVS GLS was higher and tracked superior in the uncomplicated preterm infants when compared to the preterm infants who developed BPD on echocardiogram at the time of evaluation. (C) LV global longitudinal strain (LV GLS): LV GLS was preserved and relatively unchanged from 32 weeks PMA to one year CA (p=0.6), irrespective on neonatal cardiopulmonary disease.
