Increased Risk of Pulmonary Embolism Among US Decedents With Sarcoidosis From 1988 to 2007

BackgroundA recently published report from the United Kingdom suggested an association between sarcoidosis and pulmonary embolism (PE). We sought to examine whether this association was present among US decedents with sarcoidosis.MethodsWe used data from the National Center for Health Statistics to investigate the association between sarcoidosis and PE among US decedents from 1988 to 2007.ResultsFrom 1988 to 2007, there were 46,450,489 deaths in the United States and 23,679 decedents with sarcoidosis mentioned on their death certificates. Among these, 602 (2.54%) had PE mentioned on their death certificates, compared with only 1.13% of the background population (P < .0001 for comparison). The association between sarcoidosis and PE was significant regardless of gender (OR, 2.07; 95% CI, 1.80-2.39; P < .0001 for men and OR, 1.76; 95% CI, 1.59-1.96; P ≤ .0001 for women) or race (OR, 1.57; 95% CI, 1.41-1.76; P < .0001 for blacks and OR, 1.87; 95% CI, 1.63-2.14; P < .0001 for whites). Among decedents with sarcoidosis, there was no difference in risk of PE between men and women (2.30% vs 2.54%, χ2 = 1.32, P = .25) or between blacks and whites (2.60% vs 2.23%, χ2 = 3.09, P = .08). The association between sarcoidosis and PE held regardless of age.ConclusionsUsing death certificate data from 1988 to 2007, we detected an association between sarcoidosis and PE regardless of gender, race, or age. Further investigation is needed to decipher the mechanisms of this apparent association.
