Several haemostatic and thrombotic factors, such as thromboxane A2 (Pignatelli et al., 2012; Ajayi and Halushka, 2005), endothelin-1 (Polderman et al., 1993; van Kesteren et al., 1998; Sahebkar et al., 2015), nitric oxide (Pignatelli et al., 2012; Rosselli et al., 1998) and possibly thrombin (Orsi et al., 2019; Ferenchick et al., 1995), may be driven by androgens and likely play a role in IHD (Schooling et al., 2018b; Zhao, 2018; Nikpay et al., 2015). Here, EDN1 is linked to myocardial ischemia.
