The Grieving Heart: The Association Between Hemodynamic Responses to Grief Recall and Prolonged Grief Disorder...

Area of Science:

• Psychology
• Cardiovascular Health
• Stress Response

Background:

• Grief is a significant stressor linked to increased morbidity and mortality.
• Grief involves not only psychological distress but also physical components like elevated blood pressure (BP).
• Understanding the cardiovascular impact of grief is crucial for bereaved individuals.

Purpose of the Study:

• To investigate hemodynamic responses to a grief-related interview.
• To examine how grief severity impacts cardiovascular reactivity in bereaved individuals.
• To assess the utility of a grief recall task in measuring these responses.

Main Methods:

• Sixty-seven bereaved participants (6-24 months post-loss) underwent BP measurements.
• A grief recall task (GR) was used to elicit stress responses.
• Repeated measures ANOVAs analyzed systolic (SBP) and diastolic BP (DBP) changes, comparing prolonged grief disorder (PGD) subgroups.

Main Results:

• SBP and DBP significantly increased post-GR and remained elevated during recovery.
• Significant differences were observed between baseline and post-GR BP measurements.
• The PGD subgroup exhibited higher baseline BP and a delayed BP decline compared to others.

Conclusions:

• Higher PGD symptoms are potentially linked to a dysregulated hemodynamic stress response.
• The grief recall task is a feasible method for eliciting grief-related hemodynamic responses.
• Findings highlight the physical impact of grief and PGD on cardiovascular health.
