Sequelae associated with systemic hypertension in infants with severe bronchopulmonary dysplasia

Abstract

Abstract Objectives To ascertain correlation between systemic hypertension and respiratory sequelae amongst infants with BPD. Study design Retrospective evaluation of six-year data compared infants with severe BPD to infants with no BPD. 7-day morning blood pressure (BP) (360−366 week) was compared with 95th centile cut-offs. Results 57 infants with BPD were compared with 114 infants with no BPD. Gestation and birthweight were comparable (median [interquartile range], (27 [25, 28] vs. 26.5 weeks [25, 28], p = 0.7 and 706 g [611, 884] vs. 730 [630, 895]), p = 0.1. Number of infants having BP ≥ 95th centile was significantly higher in BPD cohort (systolic BP, 23/57 [40.3%] vs. 3/114 [2.6%], p < 0.001 & mean arterial BP, 26/57 [46%] vs. 3/114 [2.6%], p < 0.001). Amongst BPD infants, higher BP was associated with longer duration of respiratory support (median [range], 109 days [81–138] vs. 87 [58–109], p < 0.001). Conclusions Infants with severe BPD had higher BP compared to those without BPD.
