Adjusted hazard ratios of composite outcome by combined hs-cTnT and NT-proBNP (P-for interaction=0.30). Adjusted for age at MI, female, race*field center, prior heart failure, hypertension, diabetes, prior stroke, coronary artery bypass graft, peripheral artery disease, chronic kidney disease, current smoking, and calendar year of MI (≥2005 vs. <2005), and elapsed time between premorbid biomarker measurements and incident MI.
