The present study aimed at investigating whether resting vagally mediated heart rate variability (HRV) as a trait-like biomarker of cognitive inhibitory control capacity is related to suicide ideation in a sample without suicide attempt history.
The relation between resting vagally mediated HRV and suicide ideation may be interpreted as indicating that reduced inhibitory cognitive control capacity may be a risk factor for suicidality. It may act already early in the suicidal process, before suicidal behavior develops and should be further investigated as potentially clinically important physiological predictor of suicidality.
