Do heart rate variability indices present potential to predict late postmenopausal? A retrospective study

Abstract

OBJECTIVES: This study aimed to compare heart rate variability indices in early and late postmenopausal women and assess their correlation and prognostic value to predict late postmenopausal. METHODS: An observational and retrospective study was performed with the medical records of patients from Hospital das Clínicas, Faculdade de Medicina da Universidade de Sao Paulo between 2018 and 2019. We selected medical records of women with menopause, over 40 years old, which were divided into two groups, according to postmenopausal time, i.e., early and late postmenopausal. RESULTS: We analyzed data from 123 women (55 in the early and 68 in the late postmenopausal group). RRtri (triangular index) was lower in the late postmenopausal group (8.68 vs. 7.15, p=0.040). There was a significant weak negative correlation in SDNN, RRtri, and SD2 and postmenopausal time. RRtri presented the potential to predict late postmenopausal. CONCLUSION: The increase in postmenopausal time decreases global heart rate variability indices. The geometric index RRtri was significantly lower in late postmenopausal women and presented the potential to predict late postmenopausal.

“…In our study, we also evidenced an increase in sympathetic activity and a decrease in vagal tone, and a decrease in the LF/HF ratio, considered a marker of sympathovagal balance. This is in spite of a previous study demonstrating that the RRtri geometric index was significantly lower in older women, with lower global HRV indices 13 . Age and gender can significantly contribute to the association between HRV and inflammatory states.…”
