Primary Outcome Measures:
  • endothelium-dependent dilatation [ Time Frame: 3 month ]

Secondary Outcome Measures:
  • pressure-induced tone and vascular morphology [ Time Frame: 3 month ]

Enrollment: 66
Study Start Date: January 2003
Study Completion Date: August 2004
Arms Assigned Interventions
Placebo Comparator: 1 Drug: placebo

combined daily

Detailed Description:
We aim to study the effects of different hormone replacement therapies (HRT) on the function and morphology of resistance arteries, and to look for their mechanistic basis. We expect that HRT with estrogens or in combination with MPA may benefit the function of resistance arteries and may preserve the morphological integrity of endothelial cells by regulatory actions on the cytoskeleton.
