Abstract

Background Posttraumatic stress disorder (PTSD) has been linked to increased morbidity. An inflexibility of the autonomic nervous system might be the underlying mechanism. We aimed to assess whether PTSD and combat trauma exposure are associated with lower heart rate variability (HRV), a measure of autonomic function and a predictor of death.Methods We measured HRV by power spectral analysis on 24-hour ambulatory electrocardiogram in 459 middle-aged veteran male twins. Combat trauma was assessed with the combat exposure scale, and current and remitted PTSD was assessed with the Structured Clinical Interview for Psychiatry Disorders. Mixed-effects regression models were used to test associations of PTSD and HRV between and within twin pairs.Results Of all twins, 211 had combat exposure, 31 had current PTSD, and 43 had remitted PTSD. Current PTSD was inversely associated with very-low-frequency and low-frequency HRV both in individual twins and within 20 pairs discordant for current PTSD. Twins with current PTSD had a 49% lower low-frequency HRV than their brothers without PTSD (p<.001). Remitted PTSD was not associated with HRV. Results were robust to adjustment for depression and other risk factors. Combat exposure was inversely associated with most HRV frequencies, but this association mostly diminished after adjustment for current PTSD.Conclusion In middle-aged veteran men, combat exposure and current PTSD are associated with measures of autonomic inflexibility previously shown to have prognostic significance. The negative health impact of combat exposure on autonomic function is mediated largely through PTSD and might reverse with remission of PTSD.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • At least a portion of the negative health consequences of PTSD may be reversible if treated early.

    “This suggests that at least a portion of the negative health consequences of PTSD may be reversible if treated early (Shah et al., 2013).”

    From Maladaptive autonomic regulation in PTSD accelerates physiological aging (2015) · cites this paper as Shah et al., 2013

    The Discussion reports that remitted PTSD was not associated with impaired autonomic function, suggesting possible reversibility after PTSD symptoms resolve. The paper does not establish that early treatment produces remission or reverses broader negative health consequences; its finding concerns autonomic function in middle-aged male veterans. (LLM, conf=0.85)

  • HRV is used to gauge psychological distress, such as PTSD.

    “is used to gauge psychological distress, such as PTSD [63]”

    From A randomized controlled trial of yoga vs nonaerobic exercise for veterans with PTSD: Understanding efficacy, mechanisms of change, and mode of delivery (2021) · cites this paper as [63]

    The Introduction describes HRV as an indicator of autonomic function, and the Results (PTSD and HRV) report lower LF and VLF HRV in twins with current PTSD. The paper therefore supports an association with PTSD, but it does not say HRV is used to gauge psychological distress or diagnose PTSD; remitted PTSD was not associated with lower HRV. Page numbers are unavailable in our copy. (LLM, conf=0.83)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
