Magnitude and Duration of Cardiovascular Responses to Anger in Vietnam Veterans With and Without Posttraumatic Stress Disorder

This study investigated the cardiovascular responses to a relived anger task in 118 male Vietnam combat veterans (62 with posttraumatic stress disorder [PTSD] and 56 without PTSD). Participants completed standardized diagnostic measures, hostility measures, and a laboratory session in which they relived a self-chosen anger memory while heart rate (HR), systolic blood pressure, and diastolic blood pressure (DBP) were measured continuously using an Ohmeda Finapres monitor. Compared with veterans without PTSD, PTSD veterans took less time to feel anger, had greater mean HR and DBP response during relived anger, and reported greater anger and anxiety during the task. There was a significant relationship between covert hostility and anger response during and after the anger task only in participants with PTSD.
