A research from RCSI College of Drugs and Well being Sciences has gained new insights into adjustments in coronary heart perform and blood strain within the lungs of infants born with Down Syndrome.
Coronary heart and lung circumstances are widespread in infants born with Down Syndrome and may contribute to the requirement for intensive care and longer hospital admissions for infants with Down Syndrome in comparison with infants with out Down Syndrome. The findings of this work will assist clinicians to raised asses one in 600 infants who’re born with Down Syndrome in Eire yearly.
Revealed within the Journal of the American Society of Echocardiography, the research is the primary of its sort to observe infants with Down Syndrome over the primary two years of age to research coronary heart perform and elevated blood strain within the blood vessels of their lungs. Seventy infants with Down Syndrome had been adopted on this research by collaboration between three neonatal intensive care models in Dublin, Eire.
This analysis discovered that the infants with Down Syndrome have impaired adjustments in coronary heart perform and blood strain within the lungs over the primary two years of age Importantly, there have been no variations in coronary heart perform between these infants with Down Syndrome who had congenital coronary heart illness in comparison with these with out over the research interval. It is a vital discovering and signifies that every one infants with Down Syndrome ought to have their coronary heart perform and blood strain of their lungs monitored throughout childhood.
Till this level, there was a dearth of proof to elucidate why infants with Down Syndrome expertise these points. The outcomes of this research present us that infants with Down Syndrome expertise adjustments within the coronary heart perform that results in elevated blood strain within the lungs.”

First creator on the research, Dr Aisling Smith, a Neonatology Specialist Registrar who carried out the analysis as a part of her PhD at RCSI commented: “This research will assist clinicians to raised perceive the mechanisms inflicting these issues and highlights the significance of monitoring coronary heart perform in infants with Down Syndrome over time.”
Roughly half of infants born with Down Syndrome even have congenital coronary heart illness. On this research, 48 infants with Down Syndrome had congenital coronary heart illness and 22 didn’t. The outcomes from the infants with Down Syndrome had been in comparison with 60 infants with out Down Syndrome (controls). All infants enrolled within the research underwent a coronary heart scan (echocardiogram) to evaluate coronary heart perform at six months, one yr and two years of age.
The analysis was performed by RCSI in collaboration with the Rotunda, Coombe and Nationwide Maternity Hospitals in Dublin; the Division of Paediatric Cardiology, Kids’s Well being at Crumlin Hospital, Dublin; Division of Paediatrics and Youngster Well being, Trinity Faculty Dublin, Boston Kids’s Hospital and Harvard Medical College, Boston, Massachusetts, USA.
The research was funded by the Well being Analysis Board Eire and the Nationwide Kids’s Analysis Centre.
