Study Summary

Copenhagen Baby Heart Study - Impact (CBHS-I) is an extension to Copenhagen Baby Heart (CBH) which included over 25.000 new-borns in the Copenhagen area between 2016-2018.

Based on clinical and subclinical deviations in the examinations in CBH, subgroups of participants will be invited to clinical examinations (echocardiography and electrocardiogram) in early childhood. There will also be a new, targeted inclusion based on certain exposures during pregnancy.

The main objectives are to assess the prevalence of congenital and inherited heart disease and, and the development of these during early childhood; examining the association between pre- and postnatal exposure, disease, lifestyle, environmental and genetic factors; continue to establish reference values for echocardiography in Danish neonates and children.

Study Description

Copenhagen Baby Heart Study - Impact (CBHS-I) is an extension to Copenhagen Baby Heart (CBH) which included over 25.000 new-borns in the Copenhagen area between 2016-2018.

Purpose:

  1. To assess the prevalence of congenital and inherited heart disease not detected prenatally, and through follow-up asses the consequence of these, e.g., bicuspid aortic valve and septal defects.

  2. To assess the prevalence of structural and functional anomalies detected by echocardiography and electrocardiography shortly after birth and, by follow-up examination, assess the consequence of these in early childhood.

  3. To establish reference values for echocardiography and ECG for Danish children.

  4. To assess the association between high-risk pregnancies and complications during pregnancy (e.g., twin/multiple pregnancy, assisted human reproduction, preeclampsia, and gestational diabetes) and the risk for congenital heart disease in the offspring and early childhood.

  5. To assess the association between maternal chronic diseases (e.g., thyroid disorders or pre-existing diabetes) and the risk for congenital heart disease in the offspring and early childhood.

  6. To assess the life-long development of cardiovascular disease as well as other conditions and to study associations between both pre- and postnatal exposure and disease, including lifestyle, environmental and genetic factors.

Methods The birth cohort of CBH constitute over 25.000 new-borns. At birth an umbilical cord blood sample was taken and immediately analysed for routine biochemical markers, and samples were also stored for possibility of future analyses and DNA sequencing.

All clinical examinations (echocardiography, electrocardiography, and measurement of oxygen saturation) took place within the first 2nd month of life, the vast majority within the 1st month, median age at examination was 11 days (interquartile range 7-15). In addition to this CBH has built a unique and extended database which include information about the maternal and paternal health, the pregnancy and birth.

As part of CBHS-I subgroups of the CBH cohort (e.g., children born to mothers with diabetes or preeclampsia, or children with abnormal findings at baseline examinations in CBH) will be invited for follow-up examinations (echocardiography and electrocardiography). There will also be a new inclusion of new-borns from the same geographical area and Hospitals as in CBH in order to expand some of the sub cohorts, e.g., children born to mothers with diabetes.
