Cardiovascular Problems in Bipolar Disorder May Begin in Adolescence
Adults with bipolar disorder have higher rates of cardiovascular disease and premature death from cardiovascular illness than the general population. At the 2012 meeting of the American Academy of Child and Adolescent Psychiatry, Benjamin Goldstein presented a poster in which he showed that youth with bipolar disorder may also have abnormal cardiovascular function.
When a tourniquet is applied, blood vessels normally expand to make up for the period of oxygen deprivation. This does not happen as readily in patients with mood disorders. This lack of flexibility and compensatory response could be one of the reasons for increased cardiovascular difficulties in those with mood disorders.
In Goldstein’s study, noninvasive ultrasound imaging was used to measure the thickness of the walls of the carotid artery and flow mediated dilation of the artery in adolescents with bipolar disorder and those without the illness. The data was collected by a certified ultrasound technologist who remained blind to the patients’ diagnostic and symptom status.
Goldstein found highly abnormal results in 14 adolescents aged 14 to 19 with bipolar disorder compared to controls. He concluded that reducing cardiovascular risk in bipolar disorder is a pressing clinical and public health challenge and that treating these patients while they are adolescents may offer considerable advantages both for prevention and for understanding the progression of cardiovascular problems in patients with bipolar disorder.
