Key result
Female borderline personality disorder patients with comorbid PTSD exhibited significantly lower high-frequency heart rate variability during an emotion regulation task compared to those without PTSD and healthy controls.

Population
84 female participants, including 57 patients with borderline personality disorder and 27 healthy controls.
Comparison
Emotion regulation task. vs Healthy controls and BPD patients without PTSD.

Does comorbid PTSD affect high-frequency heart rate variability during an emotion regulation task in female patients with borderline personality disorder?
p-value: p=0.002
Reduced high-frequency heart rate variability in borderline personality disorder is specifically associated with comorbid PTSD rather than BPD alone.
Krause-Utz et al. (2018) conducted an observational in Borderline personality disorder with or without comorbid PTSD (n=84). Comorbid PTSD in Borderline Personality Disorder vs. BPD without PTSD and Healthy Controls was evaluated on High-frequency heart rate variability (HF-HRV) during an emotion regulation task (p=0.002). Female borderline personality disorder patients with comorbid PTSD exhibited significantly lower high-frequency heart rate variability during an emotion regulation task compared to those without PTSD and healthy controls.
