Objective:
To determine the effect of tibolone treatment on brachial artery pulsatility index (PI), resistance index (RI), and flux-mediated dilation (FMD) in postmenopausal Mexican women.
Method:
The FMD, PI, and RI of the right brachial artery were measured in 19 postmenopausal women before and after they received a hyperemic stimulus, first at baseline and then following a 6-month treatment with 2.5 mg of tibolone per day. Statistical analysis was performed using the t test.
Results:
The mean+/-SD age was 52.2+/-3.9 years; time since menopause was 24.6+/-16.7 months; and treatment duration was 5.7+/-2.0 months. Compared with prestimulus measurements, a significant poststimulus increase in arterial diameter and a significant decrease in PI were observed at baseline. Compared with prestimulus measurements, a significant poststimulus increase in arterial diameter and a significant decrease in both PI and RI were observed post-treatment.
Conclusion:
Tibolone treatment had a favorable effect on brachial artery responses to hyperemic stimuli.

Prepare for the Procedure:
Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.
Hormonal Regulation of Blood Pressure
Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...
