Abstract

AIM:

To assess possible differences in serum cholesterol, low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), triglycerides, arteriosclerosis index, established risk factor (ERF) of arteriosclerosis, and 10-year risk for coronary disease according to the Adult Treatment Panel III (ATP-III) between veterans with combat-related posttraumatic stress disorder (PTSD) and a control group consisting of patients with major depressive disorder.

METHOD:

We determined serum cholesterol, LDL-C, HDL-C, and triglycerides in the patients with PTSD (n = 103) and patients with major depressive disorder (n = 92), using the enzyme-assay method. AI, ERF, and ATP-III were calculated from cholesterol, LDL-C, and HDL-C levels. The groups were matched in age and body mass index (BMI). Patients with major depressive disorder were chosen as a control group because they do not have changes in serum lipids.

RESULTS:

Patients with combat-related PTSD had higher mean concentration of cholesterol (6.2+/-1.1 mmol/L vs 5.3+/-0.9 mmol/L; p<0.001), LDL-C (3.9+/-0.7 mmol/L vs 3.5+/-1.0 mmol/L; p = 0.005), and triglycerides (2.9+/-2.3 mmol/L vs 1.5+/-0.5 mmol/L; p<0.001), and lower HDL-C (1.0+/-0.3 mmol/L vs 1.3+/-0.2 mmol/L; p<0.001) than the control group. Arteriosclerosis index (4.2+/-1.2 vs 3.7+/-1.7; p = 0.050), ERF (6.4+/-1.9 vs 5.5+/-2.4; p = 0.010), and ATP-III (12.1+/-3.3 vs 10.2+/-3.8; p<0.001) were higher in PTSD than in the control group.

CONCLUSION:

Elevated concentrations of serum lipids are associated with combat-related PTSD. This may imply that patients with combat-related PTSD are under a higher risk for arteriosclerosis.
