Summary

This completed study looked at 168 adults with a history of trauma to see if PTSD harms blood vessel function, which could raise heart disease risk. Participants completed behavioral tasks measuring fear and attention, and had their blood vessel health checked. The goal is to understand how PTSD might lead to heart problems, so at-risk people can be identified earlier.
