Does progestogen-estrogen replacement therapy alter heart rate variability and blood pressure in healthy postmenopausal women compared to estrogen alone or no therapy?
Progestogen-containing hormone replacement therapy attenuates heart rate variability and offsets the blood pressure-lowering effects of estrogen in postmenopausal women, potentially explaining adverse cardiovascular signals in prior trials.
