Key result
High adverse childhood experience exposure linked to ~18% higher risk of incident AF.
Why the study?
Although adverse childhood experiences are prevalent and alter stress response and autonomic nervous systems, information on their cardiac impact has not been incorporated into the pediatric clinical care paradigm.
Does childhood trauma contribute to atrial fibrillation and stroke risk via the intrinsic cardiac nervous system and reduced heart rate variability, and can non-pharmacological interventions prevent these outcomes in trauma-exposed individuals?

This narrative review proposes a neurocardiological framework linking adverse childhood experiences to adult atrial fibrillation and stroke risk through autonomic dysfunction and reduced heart rate variability, advocating for early pediatric screening and non-pharmacological interventions.
Adverse childhood experiences (ACEs) occur in about 64% of children living in high-income countries and even greater percentages in low- and middle-income countries. However, no information on the cardiac impact of ACEs has been incorporated into the pediatric clinical care paradigm. ACEs lead to permanent changes in the stress response systems, the autonomic nervous system and hypothalamus–pituitary–adrenal axis. The atrial fibrillation (AFib) may increase the risk of ischemic stroke five-fold and is responsible for 20% to 30% of stroke cases worldwide. This narrative review will incorporate the results from epidemiological, neurocardiological, and developmental studies to propose the intrinsic cardiac nervous system (ICNS) and heart rate variability (HRV) as key mechanisms that link early-life trauma to AFib. Individuals exposed to a high burden of ACEs had an 18% increased risk of AFib incidence (hazard ratio (HR) 1.18; 95% CI, 1.05–1.33), and each ACE-linked psychiatric diagnosis significantly reduces HRV and increases arrhythmia risk independently. This association is observational and weaker than that reported for ischemic heart disease. Trauma experienced during critical developmental stages of the ICNS interferes with its proper development, causing a sympathetically biased and AFib-prone nervous system in adolescence or early adulthood. In observational data, a healthy lifestyle was associated with up to 47% lower AFib risk among trauma-exposed adults. This has not been tested in children. Effective non-pharmacological interventions, including psychotherapy, HRV biofeedback, educational therapy, mind–body methods, physical exercise, and vagal neuromodulation, improve both psychiatric status and HRV. A neurocardiological developmental paradigm is presented, where HRV assessment and a combined approach to psychological and cardiac health prevention are important elements of pediatric practice.

Tan et al. (2026) conducted a review in Atrial fibrillation and adverse childhood experiences. High burden of adverse childhood experiences (ACEs) vs. No adverse childhood experiences was evaluated on Atrial fibrillation incidence (HR 1.18, 95% CI 1.05-1.33). High adverse childhood experience exposure is associated with an 18% increased risk of incident atrial fibrillation in observational cohort data.
