| Sumario: | Abstract: Background: Heart rate variability (HRV), a measure of autonomic nervous system activity, has been studied in a
number of psychiatric disorders during the resting state but evidence on its circadian patterns in Major
Depressive Disorder (MDD) and Borderline Personality Disorder (BPD) is scarce. We sought to identify and
differentiate HRV circadian patterns in MDD, BPD and healthy controls (HC) while exploring potential physiological
mechanisms associated with mood and emotion dysregulation.
Methods: 24-Hour electrocardiographic recordings were obtained from fifty subjects (16 HC, 18 BPD, 16 MDD).
HRV was calculated during sleep and wake periods. Associations with mood and affect measures, and with
cognitive emotion regulation strategies and self-reported difficulties in emotion regulation (DERS) were examined.
Participant’s resilience traits were explored in relation to mood and emotion regulation variables.
Results: Lower diurnal measures of HRV (i.e, RMSSD and HF) were observed in MDD subjects compared to HCs.
Decreased HF was observed during wake vs. sleep in MDD patients. HAM-D and negative affect scores negatively
correlated with HRV in MDD and BPD respectively. MDD and BPD exhibited a positive relationship between the
implementation of emotion regulation strategies and HRV compared to HC. Increased resilience was associated
with lower HAM-D and DERS scores in BPD and HC.
Conclusion: HRV alterations characterized by low diurnal cardiac parasympathetic control constitute a potential
trait biomarker of major depression and psychiatric vulnerability to depressive episodes in BPD. HRV anomalies
in MDD may persist during clinical remission. Diurnal HRV may represent a psychophysiological index of mood
and emotion regulation. |
