PTSD may affect blood vessel health in veterans

Study Highlights: Post-traumatic stress disorder may decrease the ability of blood vessels to dilate, raising the risk of heart attack and stroke in Veterans. Traditional risk factors such as high blood pressure, diabetes, high cholesterol and smoking, have not fully explained why people with PTSD seem to be at higher heart disease risk. Better ways of managing PTSD and other types of stress are needed to help reduce the negative impact of chronic stress on blood vessels.
