Blood urea nitrogen is associated with long-term all-cause mortality in stable angina pectoris patients: 8-year follow-up results

Elevation of blood urea nitrogen (BUN) indicates renal dysfunction and is associated with increased mortality in cardiovascular diseases.
The authors investigated the relationship between the blood urea nitrogen concentration measured at hospital admission and the long-term all-cause mortality in 344 patients with stable angina pectoris, during a mean follow-up period of 8 yrs.
Take-home message: In these patients with stable angina pectoris, the blood urea nitrogen concentration was associated with all-cause mortality. A concentration above 16.1 mg / dl had 90.1 % sensitivity and 60 % specificity for predicting mortality (odds ratio 2.23).
