While men are 4-5 times more likely to develop the disease, women are more likely to experience complications. Currently, screening for abdominal aortic aneurysms in women is not recommended due to the low incidence of the disease. However it remains clear that some women do develop the disease and for those who do, the consequences can be dire. Identification of risk factors beyond those classically associated with aneurysm development could be critical in improving how we care for women. We recruited healthy men and women and used MRI to quantify abdominal aortic hemodynamics to assess if men are exposed to more pro-inflammatory wall shear stress than women. We evaluated innate vascular properties that we expected to both exert control over aortic hemodynamics and to be significant different between the sexes. We used non-contrast angiograms to assess curvature and size of the aorta and to assess if either of these affected the extent of pro-inflammatory oscillatory shear. In light of the increased risk for aneurysms in patients with above the knee amputations and spinal cord injuries, we assessed differences in peripheral resistance between the sexes as mediated by uterine artery flow and measured by internal iliac artery flow oscillations. To do this, we recruited patients with uterine fibroids and hysterectomies whom we expected to have altered uterine artery resistance profiles. Finally we used a novel MRI sequence application to measure displacement and strain in the aortic wall and assess differences between the men and women.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E \u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"The influence of sex-dependent vascular properties on aortic hemodynamics"}],"uid":"27707","created_gmt":"2016-06-14 12:55:04","changed_gmt":"2016-10-08 02:18:03","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2016-06-17T11:00:00-04:00","event_time_end":"2016-06-17T13:00:00-04:00","event_time_end_last":"2016-06-17T13:00:00-04:00","gmt_time_start":"2016-06-17 15:00:00","gmt_time_end":"2016-06-17 17:00:00","gmt_time_end_last":"2016-06-17 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
