Oxytocin increases autonomic cardiac control: Moderation by loneliness

Abstract

The current study examined the role of perceived social isolation in moderating the effects of oxytocin on cardiac autonomic control in humans. Intranasal administration of 20 IU oxytocin resulted in a significant increase in autonomic (parasympathetic and sympathetic) cardiac control. Specifically, oxytocin increased high frequency heart rate variability, a relatively pure measure of parasympathetic cardiac control, and decreased pre-ejection period, a well-validated marker of enhanced sympathetic cardiac control. Derived metrics of autonomic co-activity and reciprocity revealed that oxytocin significantly increased overall autonomic cardiac control. Furthermore, the effects of oxytocin on cardiac autonomic control were significantly associated with loneliness ratings. Higher levels of loneliness were associated with diminished parasympathetic cardiac reactivity to intranasal oxytocin. The effects of OT on autonomic cardiac control were independent of any effects on circulating pro-inflammatory cytokine or stress hormone levels. Thus, lonely individuals may be less responsive to the salubrious effects of oxytocin on cardiovascular responsivity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
