MedicalResearch.com: What is the background for this study?

Response: Carotid atherosclerosis is one of most important risk factors for developing stroke. Carotid atherosclerotic plaques characterized by lipid core presence and intraplaque haemorrhage are considered to be unstable, and therefore more prone to rupture and lead to consequent stroke. Sex differences have been observed in carotid plaque composition as well as in stroke incidence. Sex hormones, particularly estrogen and testosterone actions are suggested to underlie the observed sex differences in atherosclerosis. Experimental evidence suggests a direct action of estradiol and testosterone on the vascular system, affecting various mechanisms that may impact plaque composition and subsequently stroke risk.
