Objectives: To assess combat and combat-related posttraumatic stress disorder (PTSD) as risk factors for heart disease and non-cardiac chronic disease comorbidity in deployed Vietnam veterans 50 years post-War.
Methods: A random sample of 735 Vietnam-deployed American Legionnaires was surveyed in 1984, 1998, and 2000 for combat exposure, probable PTSD, and history of diagnosed chronic illnesses.
Results: Twenty-eight percent reported a diagnosed heart condition; combat exposure in Vietnam was a significant predictor (OR = 1.92, 95% confidence interval 1.13-3.31). Veterans with heart disease reported significantly more comorbid chronic illnesses, including arthritis and respiratory conditions: sleep apnea, emphysema, and asthma. Chronic illnesses were reported more often by men with PTSD.
Conclusion: Emerging evidence suggests that 50 years after Vietnam combat and associated PTSD may contribute to heart disease and comorbid conditions.
