News & Events: Vascular Endothelial Function

The multifaceted rarefied career of Marlene Grenon, M.D., C.M., aspiring astronaut cum UCSF vascular surgeon, was recently profiled in the October 2106 issue of "Vascular Specialist", a publication of the Society for Vascular Surgery (SVS) with a worldwide audience of vascular surgeons, interventional cardiologists, vascular and interventional radiologists, and other specialists. Dr. Grenon, an Associate Professor in the Division of Vascular and Endovascular Surgery, has been on leading edge of research on how the human body, in particular the cardiovascular system, fares under the rigors of [...]

UCSF News reports on a recent study led by UCSF researchers linking post-traumatic stress to a higher risk for cardiovascular disease and death. The results of the research were reported in the March 2016 issue of the Journal of the American Heart Association. Marlene Grenon, M.D., C.M. Associate Professor in the Division of Vascular & Endovascular Surgery, was the lead author of the paper and played a pivotal role in the research. The paper is the result of a collaborative effort among cardiology, vascular surgery, and psychiatry at the San Francisco VA Health Care [...]

A clinical study led by UCSF Vascular Surgeon Marlene Grenon, M.D., C.M. looked at the effects of physical inactivity on vascular endothelial function and arterial stiffness, two measures that relate to cardiovascular risk. The results showed that a short term exposure to physical inactivity leads to quantifiable impairment in endothelial function, artery wall stiffness and diastolic blood pressure. The group hypothesized that this may be associated with a vascular deconditioning state. These findings have the potential for widespread relevance: in hospitalized and post-operative patients, [...]
