How to Screen Older Veterans for Comorbid CVD and PTSD
How should clinicians screen older veterans for co-occurring cardiovascular disease and PTSD in routine care?
Older veterans with both cardiovascular disease and PTSD represent a small but high-need subgroup with substantially worse psychiatric, medical, cognitive, and functional burden than veterans with either condition alone. This guide applies when an older veteran already has CVD or PTSD, or when the clinician is trying to decide who warrants bidirectional screening for both conditions.
-
Identify older veterans who merit bidirectional screening
Prioritize veterans aged 60 years and older because this is the population studied. Bidirectional screening is especially relevant when either CVD or PTSD is already known, as 30.8% of older veterans in this sample had CVD and/or PTSD, including 23.1% with CVD only, 5.5% with PTSD only, and 2.2% with both conditions.
-
Ascertain whether cardiovascular disease is already present
Ask about prior clinician-diagnosed heart disease, heart attack, or stroke, which were the study definitions used to identify CVD. If any of these are present, treat the veteran as having CVD for purposes of comorbidity case-finding and proceed to PTSD-focused assessment.
-
Ascertain whether PTSD is already present
Determine whether the veteran has PTSD using the same construct assessed in the study, which relied on self-reported PTSD status. If PTSD is present, proceed to cardiovascular and medical review because veterans with PTSD only may still belong to the higher-burden comorbid group if CVD is also present.
-
Use history factors that mark higher comorbidity risk
Raise suspicion for CVD+PTSD in older veterans who are combat veterans, have greater childhood adversity, or report more lifetime traumatic events, because these factors independently characterized the comorbid group relative to controls and CVD-only veterans. Also note lower likelihood of being married or partnered, which was associated with the comorbid group versus controls and versus CVD only.
-
Check for modifiable clinical correlates that strengthen concern
Specifically ask about history of nicotine use disorder and high blood pressure, as both were independently associated with CVD+PTSD relative to controls, and high blood pressure also distinguished CVD+PTSD from PTSD only. The article concludes that early detection and management of modifiable risk factors such as smoking, inactivity, poor sleep, and co-occurring depression, anxiety, and substance use may help reduce downstream cardiovascular risk.
-
Escalate to integrated care when both conditions are present
If the veteran has both CVD and PTSD, move beyond siloed management because this subgroup had the poorest outcomes across physical, mental, psychosocial, and cognitive domains. The article supports trauma-informed, integrated cardiovascular and mental health care and states that routine bidirectional screening may be warranted in this population.
Clinical Considerations
- The study was cross-sectional, so these associations support case-finding but do not establish that PTSD caused CVD or that CVD caused PTSD symptoms.
- CVD was identified by self-report of a prior professional diagnosis, so undiagnosed cardiovascular disease may not have been captured.
- PTSD and other mental health measures were based on self-report rather than diagnostic interviews.
- The sample was predominantly male and white, which may limit generalizability to more diverse veteran populations.
Bottom Line
In older veterans, the presence of either CVD or PTSD should prompt bidirectional screening for the other condition and for modifiable correlates because the comorbid subgroup carries the greatest overall health and functional burden.
