(Seoul = Yonhap News) Correspondent Han Seong-gan = A study has found that those who were born prematurely or whose birth weight was larger than their gestational age increased the risk of developing atrial fibrillation, a type of arrhythmia later in life.
Gestational age refers to the length of time the fetus remains in the womb until birth.
Atrial fibrillation is a condition in which the upper chambers of the heart, the atria, sometimes contract very rapidly, causing the heart to quiver like jelly in a bowl, causing the heart rate to soar to over 100 beats per minute.
When atrial fibrillation occurs in the left atrium, blood can collect and form a blood clot. This blood clot is carried into the bloodstream through the left ventricle, which pumps blood throughout the body, and travels around, blocking blood vessels in the brain and possibly causing a stroke.
A research team led by Professor Fen Yang of Karolinska Medical University in Sweden conducted a study of 8,012,433 people (average age 21 years old, 51.3% male) born in three Nordic countries (excluding twins, etc.): Denmark, Sweden, and Finland. Medical news portal Medpage Today reported on the 26th that the analysis of records and medical records revealed this fact.
Of these, 4.7% were born prematurely. 10% were born as overweight babies for their gestational age, and 10% were born as light-weight babies for their gestational age. The rest were born with an appropriate body weight for their gestational age.
Of these, 11,464 (0.14%) were later diagnosed with atrial fibrillation (average age 29.3 years).
As a result of the survey, the incidence of atrial fibrillation was 71% higher in the premature heavy baby group, 55% higher in the full term heavy baby group, 31% higher in the premature normal weight group, and 25% higher in the light weight premature baby group, compared to the normal weight infant group born at full term.
Only the full-term SGA group had a 9% lower incidence of atrial fibrillation.
The research team said further research is needed to find out why this result came out.
However, the study’s findings are only applicable to childhood and young adulthood, the researchers stressed. In addition, the research team added that this study only applies to white people as it was conducted almost entirely on white people.
In response, Arti Dalal, a professor of pediatric electrophysiology at Vanderbilt University Medical Center in the US, commented that the data from this study might help predict the risk of developing atrial fibrillation in the future.
The findings were published in the latest issue of the Journal of the American Medical Association – Pediatrics (JAMA Pediatrics).
