title: Cardiovascular, hemodynamic, neuroendocrine, and inflammatory markers in women with and without vasomotor symptoms.
abstract: Vasomotor symptoms (VMS) may be associated with an increased risk of cardiovascular disease. One candidate mechanism may involve alterations in physiological responses to stress. The current study therefore examined the relationship between self-reported VMS bother and cardiovascular, hemodynamic, neuroendocrine, and inflammatory responses to an acute psychosocial stress protocol.
  
  
  
  One hundred eighty-six women in the menopausal transition or early postmenopausal stage (age 45-60 y) provided the data for this article. Subjective hot flash and night sweat bother were assessed using the Greene Climacteric Scale. Women also underwent a stressor battery involving a speech and a mental arithmetic task while cardiovascular, hemodynamic, neuroendocrine, and inflammatory responses were assessed. Repeated measures regression analyses were used to examine the relationship between self-reported VMS and physiologic responses to the stressor.
  
  
  
  In multivariate analyses adjusting for potential confounders, self-reported hot flash bother was associated with lower overall cardiac index and stroke volume index and higher overall vascular resistance index and levels of the inflammatory cytokine interleukin-6. Hot flash bother also tended to be associated with higher overall cortisol levels and higher baseline levels of plasma norepinephrine. Night sweat bother, on the other hand, was associated with higher overall cortisol levels and tended to be associated with higher interleukin-6.
  
  
  
  Self-reported VMS bother is associated with an unfavorable hemodynamic and neuroendocrine profile characterized by increased hypothalamic-pituitary-adrenal axis and central sympathetic activation, inflammation, and vasoconstriction. Further research investigating this profile in relation to VMS, and the potential health implications of this association, is warranted.
