Clinical studies have recommended that hormone replacement therapy (HRT) may perhaps be associated using a decreased danger for cardiovascular events (Folsom et al., 1995; Tremollieres et al., 2000) implying helpful effects of HRT on the cardiovascular method. This assumption was nevertheless questioned by the results obtained from the Women’s Overall health Initiative (WHI) trial: on the one hand, conjugated equine oestrogens (CEE) alone exerted advantageous effects on the cardiovascular method (Anderson et al., 2004), on the other hand their mixture with medroxyprogesterone acetate (MPA) elevated the threat of cardiovascular events, which includes stroke (Rossouw et al., 2002). The observation that HRT is connected with a larger danger for stroke (Grodstein et al., 2003; Rossouw et al., 2007; Vickers et al., 2007) may well for that reason be CYP1 Activator Purity & Documentation ascribed to prothrombotic MPA effects. Certainly, this hypothesis was confirmed in animal experiments showing that MPA enhances the thrombotic response at the very least partially through enhanced thrombin generation (Freudenberger et al., 2009). In addition to MPA, a further synthetic gestagen, norethisterone acetate (NET-A), is commonly employed in postmenopausal HRT (Koubovec et al., 2005) together with oestrogens. NET-A and MPA differ from every other with regard to agonism of other steroid receptors in addition to the progesterone receptor. Specifically, as opposed to MPA, that is recognized to possess partial glucocorticoid effects (Wiegratz and Kuhl, 2004), NET-A has been discovered to exert only minimal glucocorticoid actions (Koubovec et al., 2005). Thus, additional research making use of animal models of atherothrombosis will assistance to clarify the atherothrombotic risk distribution of synthetic gestagens and to investigate the underlying mecha.
