Table 3.

Covariate-adjusted Cox analyses of the association between change per year in cardiac troponin T levels by a highly sensitive assay (hs-cTnT) and incident atrial fibrillation (AF) in the Cardiovascular Health Study (CHS)

	Covariates	Hazard ratio*	95% Confidence interval
Model 1	Age, race, gender	1.03	1.01–1.04
Model 2	Model 1 + baseline risk factors	1.03	1.01–1.04
Model 3	Model 2 + incident HF	1.02	1.01–1.04
Model 4	Model 2 + CRP, NT–pro-BNP	1.02	1.01–1.03

Covariates in models are those in Table 2 legends with additional adjustment for baseline hs-cTnT.

CRP = C-reactive protein; HF = heart failure; NT–pro-BNP = N-terminal pro–B-type natriuretic peptide.

^*Hazard ratio for every 1 ng/L increase from baseline.
