Cardiovascular disorders (CVD) are associated with acute and posttraumatic stress responses, yet biological processes underlying this association are poorly understood. This study examined whether renin-angiotensin-aldosterone system activity, as indicated by a functional single nucleotide polymorphism (SNP) in the angiotensin converting enzyme (ACE) gene, is associated with both CVD and acute stress related to the September 11, 2001 (9/11) terrorist attacks.
Objective: Trauma exposure can precipitate acute/post-traumatic stress responses (AS/PTSD) and disabling cardiovascular disorders (CVD). Identifying acute stress-related physiologic changes that may increase CVD risk could inform development of early CVD-prevention strategies. The endocannabinoid system (ECS) regulates hypothalamic-pituitary-adrenal (HPA) axis response and stress-related cardiovascular function. We examine stress-related endocannabinoid system (ECS) activity and its association with cardiovascular biochemistry/function following acute stress.
