Abstract

Objective:To test the hypothesis that congenital heart disease (CHD) in preterm infants with severe CHD (cyanotic or left-sided obstructive lesions, or congestive heart failure) is independently associated with necrotizing enterocolitis (NEC, stage II or greater).Study design:Single-institution retrospective birth cohort of preterm infants with gestational age 23 0/7 to 34 6/7 weeks delivered between 1 January 2002 and 31 December 2011, excluding infants who received comfort care. Patients were classified into severe CHD, mild CHD and control groups.Results:Among 4678 infants, 170 (3.6%) had CHD and 118 (2.5%) developed NEC. The risk for NEC increased with severe CHD (adjusted relative risk (RR)=3.72; 95% confidence interval (CI)=1.37 to 10.10) but not with mild CHD (RR=0.65; CI=0.27 to 1.55).Conclusion:In this cohort, severe but not mild CHD was independently associated with increased risk for NEC. This finding, if confirmed by other studies, may help identify patients at risk for NEC.
