Sex differences in mechanisms of arterial stiffness

Jennifer J DuPont et al. Br J Pharmacol. 2019 Nov.

Abstract

Arterial stiffness progressively increases with aging and is an independent predictor of cardiovascular disease (CVD) risk. Evidence supports that there are sex differences in the time course of aging-related arterial stiffness and the associated CVD risk, which increases disproportionately in postmenopausal women. The association between arterial stiffness and mortality is almost twofold higher in women versus men. The differential clinical characteristics of the development of arterial stiffness between men and women indicate the involvement of sex-specific mechanisms. This review summarizes the current literature on sex differences in vascular stiffness induced by aging, obesity, hypertension, and sex-specific risk factors as well as the impact of hormonal status, diet, and exercise on vascular stiffness in males and females. An understanding of the mechanisms driving sex differences in vascular stiffness has the potential to identify novel sex-specific therapies to lessen CVD risk, the leading cause of death in males and females.

Basic vascular structure and stiffness‐associated pathology. The three main layers of vascular structure (tunica adventitia, tunica media, and tunica intima) are illustrated, along with pathological changes that occur in each layer with arterial stiffness. AT1R: angiotensin II type 1 receptor; MR: mineralocorticoid receptor; α‐SMA: α smooth muscle actin

Cardiovascular disease‐related pathologies and risk factors that lead to arterial stiffness. Aging, hypertension, obesity, and metabolic syndrome contribute to arterial stiffness in both males and females. In males, testosterone deficiency is associated with elevations in arterial stiffness, whereas in females, a number of clinical conditions have been associated with arterial stiffness such as pre‐eclampsia, polycystic ovary syndrome (PCOS), endometriosis, and a variety of autoimmune disorders
