Cardiac Biomarkers and Subsequent Risk of Hospitalization With Bleeding in the Community: Atherosclerosis Risk in Communities Study.

Background hs-cTnT (high-sensitivity cardiac troponin T), but not NT-proBNP (N-terminal pro-B natriuretic peptide), has been shown to predict bleeding in patients with atrial fibrillation. Whether these biomarkers are independently associated with bleeding in the general population is unknown. Methods and Results We used Cox proportional hazards models to examine the association of hs-cTnT and NT-proBNP with incident bleeding (defined by [] codes) among 9550 middle-aged men and women without a history of cardiovascular disease or bleeding. There were 847 hospitalizations with bleeding (92% from gastrointestinal bleeding) during a median follow-up of 9.0 years. Serum levels of hs-cTnT were associated with bleeding in a graded fashion, with a hazard ratio of 1.28 (95% CI, 1.06-1.59) for 6 to
