Key Dimensions of PTSD and ED

About

Brief Summary

This study will test whether endothelial dysfunction could be the early subclinical mechanism by which posttraumatic stress disorder (PTSD) increases cardiovascular disease (CVD) risk, and whether posttraumatic fear-a key component of PTSD-or another PTSD dimension could be the target to offset that risk. The results of this study may help trauma-exposed individuals who are at risk of having CVD events.
