Goldstein and colleagues interpreted data from the National Epidemiological Survey in 2001-2002 that included 41,682 representative adults in the U.S. population sampled compared with 1,411 found in the community with a diagnosis of bipolar disorder.

Those with bipolar disorder had 3.86 times higher odds of having coronary heart disease compared with those in the general population. They were also 2.15 times more likely to have hypertension. Most disturbingly, the mean age of those with coronary heart disease in the general population was 62.1 years of age, but in those with bipolar illness, it was 50.4 years of age. This indicates that the markedly increased risk and incidence of coronary artery disease occurred approximately 11 years earlier in those with bipolar illness compared with those without. Most interestingly, the number of prior depressive episodes correlated with the presence of either coronary heart disease or hypertension.
