According to a British study stress in early childhood can increase the risk of heart disease, as it affects the function of blood vessels and blood pressure.
Jennifer Pollock from the University of Alabama at Birmingham has studied the movement of blood pressure and other indicators in the blood vessels in 221 adolescents, as well as the relationship of these changes and exposure to stress in childhood. Childhood traumas associated with changes in the blood vessels are a result of dysfunction in the child’s home, neglect and abuse.
The degree of mental trauma depends on the number of traumatic events, so those who described a single traumatic event are categorized as mild people with trauma, and those who described two or more traumatic events are categorized as moderate or strong trauma. Those with one traumatic event in childhood had level endothelin (a protein that constricts blood vessels and thus increases blood pressure) in plasma on average 18 percent higher than those without trauma, and those with two or more traumas had the endothelin levels 24 percent higher than those who had not experienced trauma. Respondents with two or more described traumas had high blood pressure as well as decrease in the elasticity of blood vessels.
Pollock believes that is supposed to be determine whether the treatment of stress episodes in children have impact on reducing cardiovascular health risks later in life.
