“…The causality of the mediation chain is supported by other findings that indicate that chronic baroreflex activation leads to increased heart rate variability in dogs and patients [53]. An evolutionary role of this ‘negative affect’ mechanism of illness severity induction could be to provide a coping behavior [54–57]. …”

Objective This study was conducted to present evidence of differences in autonomic regulation of cardiovascular activity and its role in the severity of specific (disease-related) and non-specific (negative affect and chronic pain-related) symptoms in individuals with Irritable Bowel Syndrome (IBS). Methods Seventy-eight female patients with IBS and 27 healthy women age 18–62 years were assessed for IBS symptoms, negative affect, and baroreceptor sensitivity (BRS), blood pressure (BP), heart rate, and heart rate variability (HRV) at rest. Direct and indirect regression effects were examined with application of the bootstrap procedure to validate findings. Results IBS was reliably related to lower resting BRS, higher BP, and higher negative affect compared to healthy controls. Longer disease duration (chronicity) was related to BRS decrease coupled with systolic BP increase (95% CIs = -0.14 to -0.01). Three autonomic mechanisms associated with BRS decrease were found to further regulate severity of IBS symptoms. Lower BRS was related to higher IBS severity in general if the effect was transferred through the decrease of low frequency power of HRV (e.g., 95% CIs = -0.039 to -0.001 for abdominal pain severity). However, lower BRS was related to lower IBS severity in general if the effect was transferred through diastolic BP increase (95% CIs = 0.01 to 0.11 for abdominal pain severity). Lower BRS was related to higher abdominal pain severity coupled with high negative affect if the effect was transferred through the decrease of higher frequency power of HRV (95% CIs = -0.026 to -0.003). Conclusions These findings indicate that different cardiovascular mechanisms are associated with IBS development and the increase and decrease of severity of IBS symptoms. Their assessment suggests ways to personalize treatment of IBS.

“…This affect regulation may be related to other GABAergic (sedative) and serotonergic (stimulant) central pathways differing from above mentioned resilience and adaptation mechanisms of nociception regulation. From an evolutionary viewpoint, the putative “pain aggravation” mechanism is a part of a general affective alarm mechanism for enhancing or substituting insufficient sensory (visceral, proprioceptive, and nociceptive) harm‐related signaling to consciousness for behavior change to coping with the problem in those with deficits in sensory processing like some alexithymia components …”

[90][91][92][93] Lifestyle (cigarette smoking, alcohol, caffeine, and exercise) factors were additionally reviewed for their probable mediation effects through explored CV asymmetry variables on protection of health or exacerbation of IBS severity. All found effects were independent of the IBS chronicity.…”

“…Importantly, emotion regulation deficits seem to be less linked to the cognitive components of alexithymia (difficulty describing feelings) and more to affective/experiential components (i.e., difficulty identifying feelings and externaloriented thinking), suggesting that they may represent a coping mechanism in light of alexithymic individuals' inability to handle intense emotions (Constantinou et al, 2014). Other researchers similarly suggested that the EOT factor may play a protective role by directing awareness away from emotional experiences (Davydov, Luminet, & Zech, 2013).…”

Alexithymia is associated with deficiencies in recognizing and expressing emotions and impaired emotion regulation, though few studies have verified the latter assertion using objective measures. This study examined startle reflex modulation by fearful imagery and its associations with heart rate variability in alexithymia. Fifty-four adults (27 alexithymic) imagined previously normed fear scripts. Startle responses were assessed during baseline, first exposure, and reexposure. During first exposure, participants, in separate trials, engaged in either shallow or deep emotion processing, giving emphasis on descriptive or affective aspects of imagery, respectively. Resting heart rate variability was assessed during 2 min of rest prior to the experiment, with high alexithymic participants demonstrating significantly higher LF/HF (low frequency/high frequency) ratio than controls. Deep processing was associated with nonsignificantly larger and faster startle responses at first exposure for alexithymic participants. Lower LF/HF ratio, reflecting higher parasympathetic cardiac activity, predicted greater startle amplitude habituation for alexithymia but lower habituation for controls. Results suggest that, when exposed to prolonged threat, alexithymics may adjust poorly, showing a smaller initial defensive response but slower habituation. This pattern seems related to their low emotion regulation ability as indexed by heart rate variability.
