Women, PTSD, and heart disease, JAMA study confirms a strong link

Los Angeles. Despite advances in prevention and treatment and corresponding decreases in IHD mortality during the past few decades, ischemic heart disease (IHD) remains an understudied, underdiagnosed, and undertreated condition in women. A recently published study in JAMA has shown that post-traumatic disorder (PTSD) is associated with increased risk of IHD in women veterans and this may have implications for IHD risk assessment in vulnerable individuals.

Longitudinal research suggests that PTSD is associated with greater risk of IHD but much of this work has been in predominantly male veterans. Studying the PTSD-IHD association in women veterans is important, because these women represent a growing population with high levels of trauma exposure and a unique cardiovascular risk profile.

In this retrospective, longitudinal cohort study of the national Veterans Health Administration (VHA) electronic medical records, with a priori hypothesis that PTSD would be associated with greater risk of IHD onset was tested. Women veterans 18 years or older with and without PTSD were assessed for study eligibility. Exclusion criteria consisted of no VHA clinical encounters after the index visit, IHD diagnosis at or before the index visit, and IHD diagnosis within 90 days of the index visit. Propensity score matching on age at index visit, number of prior visits, and presence of traditional and female-specific cardiovascular risk factors and mental and physical health conditions was conducted to identify women veterans ever diagnosed with PTSD, who were matched in a 1:2 ratio to those never diagnosed with PTSD.
