Key result
Perceived social support was positively associated with time and frequency domain measures of heart rate variability during rest, stress induction, and recovery from an acute stressor.
Why the study?
To explore and synthesize literature evaluating the relationship between perceived social support and cardiac vagal modulation measured by HRV during phases of an acute stress response.
Does perceived social support improve heart rate variability during an acute stress response?
Systematic Review (n=8)
Does perceived social support improve heart rate variability during an acute stress response?
Increased perceived social support is positively associated with parasympathetic modulation of heart rate (HRV) during acute stress, suggesting a physiological mechanism for its stress-buffering effects.
May support psychosocial screening in cardiac stress management; extends observational links between social factors and autonomic regulation.
The purpose of this integrative review is to explore and synthesize literature about the relationship between perceived social support and cardiac vagal modulation, measured by heart rate variability (HRV), during phases of an acute stress response to assess this potential relationship underlying the stress-buffering effects of perceived social support. A systematic search of seven databases was conducted, including MEDLINE, CINAHL, PsychINFO, Embase, ProQuest, medRxiv, and clinicaltrials.gov. Eight studies met the inclusion criteria and were systematically synthesized. A quality appraisal was completed for each included study. Majority of studies focused on time and frequency domain measures of HRV thought to reflect parasympathetic modulation of heart rate and identified them as positively associated with perceived social support during rest, stress induction, and recovery from an acute stressor. Results highlight the importance for nurses and other health care professionals to assess patients' perceived social support, as increased perceived social support may contribute to an adaptive stress response.

Goodyke et al. (2021) conducted a systematic review in Acute stress response (n=8). Perceived social support was evaluated on Cardiac vagal modulation, measured by heart rate variability (HRV). Perceived social support was positively associated with time and frequency domain measures of heart rate variability during rest, stress induction, and recovery from an acute stressor.
