A groundbreaking study of 1,946 male veterans of World War II and Korea suggests that vets with symptoms of post-traumatic stress disorder are at greater risk of heart attacks as they age.
The new study is the first to document a link between PTSD symptoms and future heart disease, and joins existing evidence that vets with PTSD also have more autoimmune diseases such as arthritis and psoriasis.
A second study, funded by the Army, found that soldiers returning from combat in Iraq with post-traumatic stress disorder reported worse physical health, more doctor visits and more missed workdays. The Army study is based on a survey of 2,863 soldiers one year after combat.
"The burden of war may be even greater than people think," said the first study's lead author, Laura Kubzansky of the Harvard School of Public Health, who studies anxiety, depression and anger as risk factors for heart disease. Her work, with colleagues from Harvard and Boston University, appears in Monday's Archives of General Psychiatry.
