APS Annual Meeting at Experimental Biology

2021 Vision of Integrated Physiology – Examining Sex Differences in Cardio & Cerebrovascular Physiology

Symposium — Tuesday, April 27, 2021 — 4:00 PM - 5:30 PM — Virtual Session, Room APS-8
Environmental and Exercise Physiology Section — Chair: Tracy Baynard — Co-Chair: Sushant Ranadive

It is well established that women are not small men regarding their physiology.  Yet, the biomedical research community is only just beginning to make headway on where and what those differences are in regards to disease prevention and treatment.  We aim to present a “head-to-toe” update on the current understanding of sex differences as it relates to aspects of cardio and cerebrovascular function focused on applied approaches in humans.   Dr. Virginia Miller will provide an overall framework for the symposium, and contextualize the topics of the following speakers. Specifically, Dr. Miller will review aspects of the progression of atherosclerosis and CVD in women, which differs substantially from men, an important point considering heart disease is the number one killer of women in Western societies.  Following the overview from Dr. Miller, we start at the “head”, Dr. Jill Barnes will describe sex differences in cerebrovascular function, and how this contributes to unique risk profiles in women.  Her physiology training and experimental approaches will provide a unique lens to view these differences. Dr. Megan Wenner will discuss the most recent developments regarding sex differences in arterial function, and discuss some of her newest data of clinical importance regarding women and risk of developing hypertension particularly in endothelin receptors.  To wrap up the symposium, Dr. Qi Fu will provide an update on our understanding of sex differences specific to autonomic function, as well as provide some data related to cardiac differences.
