This is cross-over, randomized clinical trial, with objective to evaluate the effects of low-dose oral hormone therapy and non-oral hormone therapy on endothelial function markers (fibrinogen, von Willebrand factor, c-reactive protein), natriuretic peptide and on anthropometric, metabolic and hormonal variables in early and healthy postmenopausal women and analyzing polymorphisms in the estrogen receptor gene and FTO polymorphisms Patients will be randomized to receive oral hormone treatment or non-oral hormone treatment The investigators hypothesis is that a different genotypes in the receptor estrogen gene and FTO may have an influences on treatment response in metabolic markers and cardiovascular risk
Name: Estradiol and Progesterone
Name: Estradiol and Drospirenone
Description: Influence of 4 polymorphisms (PVUII, ALUI, RSAI and BSTUI) on the effect of different treatment regimens. Change from Baseline in weight, waist circumference, BMI, systolic and diastolic blood pressure, fasting glucose, glucose at 120 min, Fasting insulin, HOMA, Cholesterol, HDL-c, LDL-c, Triglycerides, Von Willebrand Factor, Fibrinogen, Testosterone and C-reactive protein at six months.
Measure: Polymorphisms of estrogen receptor Time: six monthsDescription: Influence of 2 polymorphisms (rs9939609 and rs8050136) on the effect of different treatment regimens. Change from Baseline in weight, waist circumference, BMI, systolic and diastolic blood pressure, fasting glucose, glucose at 120 min, Fasting insulin,HOMA, Cholesterol, HDL-c, LDL-c, Triglycerides, Von Willebrand Factor, Fibrinogen, Testosterone and C-reactive protein at six months.
Measure: Polymorphisms in the fat mass-and obesity-associated (FTO) gene Time: Six MonthsDescription: To assess the effects of oral low-dose and non-oral hormone therapy (HT) on ultra-sensitive C reactive protein (CRP), atrial natriuretic peptide (ANP), and cardiovascular risk factors in postmenopause.
Measure: Effects of hormone therapy on C reactive protein, atrial natriuretic peptide and cardiovascular risk factors in postmenopause. Time: Six monthsAllocation: Randomized
