Objective:
To evaluate the influence of dydrogesterone on estimated cardiovascular risk of users of hormone replacement therapy (HRT) (with percutaneous 17β-estradiol in monotherapy and in combination with dydrogesterone) and HRT non-users through the Framingham score tool for a period of 2 years.
Methods:
Framingham scores were calculated from the medical records of patients treated for at least 2 years with 17β-estradiol alone or in combination with dydrogesterone, along with HRT non-users, through the analysis of patient medical records, followed for at least 2 years at Instituto Estadual de Diabetes e Endocrinologia Luiz Capriglione.
Results:
Improvements in lipid profile, glucose and blood pressure levels, which reduced the estimated cardiovascular risk, were observed in the 17β-estradiol group. Similar changes were observed in the users of 17β-estradiol + dydrogesterone, suggesting that this progestogen does not attenuate the effects caused by 17β-estradiol.
Conclusions:
Both HRT groups showed a reduction in their Framingham score. In contrast to data from other HRT investigations on cardiovascular risk, these formulations proved to be safe, even in the first year of use.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
