【 摘 要 】

Background: Postmenopausal women are more likely to have uncontrolled hypertension and are at higher risk of cardiovascular disease compared with age-matched men. Blood pressure variability is emerging as a predictor of adverse cardiovascular outcomes and may be implicated in the relationship between menopause and worsened vascular health in women. We conducted an observational study, BRAVE (Blood pRessure And Vascular hEalth around menopause) to study this relationship. Method: Normotensive perimenopausal women were recruited. Blood pressure variability was measured through 24-h blood pressure monitoring. Vascular health was assessed through arterial stiffness (carotid-femoral pulse wave velocity), carotid intima-media thickness and endothelial function (reactive hyperemic index). Multivariate models were performed to identify factors associated with blood pressure variability and arterial stiffness in perimenopausal women. Results: Forty-nine healthy women ( mean age 52.9 +/- 4.0, 63% postmenopausal) were recruited. There was a high prevalence (40%) of night non-dipping, a measure of an abnormal pattern of blood pressure variability. Aside from night dipping, other measures of blood pressure variability were similar between premenopausal and postmenopausal women. In the multivariate analysis, body mass index was the only factor associated independently with different measures of blood pressure variability, including the maximum overnight blood pressure (beta = 1.95, p < 0.01). The latter was also significantly associated with arterial stiffness (beta = 0.035, p = 0.048). Finally, poor sleep was independently associated with an increase in arterial stiffness. Conclusions: Abnormal blood pressure variability, particularly night non-dipping, is common in normotensive perimenopausal women. Maximum overnight blood pressure is independently associated with arterial stiffness and may identify women at higher cardiovascular risk. (C) 2020 Elsevier B.V. All rights reserved.
