Conditions

Cardiovascular Disease, Post Traumatic Stress Disorder

Brief summary

This is an observational study designed to determine whether veterans with PTSD have a higher risk of heart disease than those without PTSD. Cardiovascular risk will be assessed by interview and review of medical records, carotid artery ultrasound, and blood tests measuring markers of inflammation. Study participation is approximately 6 months. The eligible study population is veterans of Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF), age 28 through 38 years.

Design outcomes

Primary

Measure	Time frame	Description
Completion of structured diagnostic interview within 2hrs.	12 months	Completion of Clinician Assessed PTSD Scale (CAPS), Alcohol Use Disorders Identification Test-Consumption (AUDIT-C), Patient Health Questionnaire-9 (PHQ-9), Pittsburgh Sleep Quality Index (PSQI), INTRuST Uniformed Data Set, and Family History of heart disease, within 2hrs.
Time from CIMT completion to completion of clinical read.	18months	Rate of clinical read will help in determining adequate staffing requirements for a larger study.
Completion of serum lab measurements.	18months	—
Recruitment methods feasibility	12 months	Comparison of the number of participants per month recruited from medical providers (with/without PTSD) vs. response to recruitment fliers (with/without PTSD) in the first 12 months of the study. Selection bias to be determined by looking at differences in age and co-morbid illnesses.
Ability to schedule Carotid Intima-Media Thickness (CIMT) ultrasound in the Vascular Lab at VA San Diego Healthcare Systems, within 4 months of enrollment	18months	Determining whether the Vascular Lab has the capacity for a larger clinical study will be informative in planning larger prospective studies.

Secondary

Measure	Time frame	Description
Cardiovascular Disease Biomarkers	Within 6 months of subject recruitment	Serum C-reactive protein and interleukin-6 will be measured
Carotid Intimal Medial Thickness (CIMT) measurement	Within 4 months of subject recruitment	CIMT thickness will be measured by carotid ultrasound
