Abstract

Whether persons without prevalent cardiovascular disease (CVD) but elevated levels of high-sensitivity cardiac troponin T (hs-cTnT) or N-terminal pro-B-type natriuretic peptide (NT-proBNP) are at high risk of infection is unknown. Using 1996-2013 data from the Atherosclerosis Risk in Communities Study, we estimated hazard ratios for incident hospitalization with infection in relation to plasma hs-cTnT and NT-proBNP concentrations among participants without prevalent CVD and contrasted them with hazard ratios for persons with prevalent CVD (coronary heart disease, heart failure, or stroke). In a multivariable Cox model, prevalent CVD was significantly associated with risk of hospitalization with infection (hazard ratio (HR) = 1.31, 95% confidence interval (CI): 1.19, 1.45). Among participants without prevalent CVD, hs-cTnT and NT-proBNP were independently associated with infection risk in a graded fashion (e.g., HR = 1.44 (95% CI: 1.24, 1.69) for hs-cTnT ≥14 ng/L and HR = 1.28 (95% CI: 1.14, 1.44) for hs-cTnT 9-13 ng/L vs. <3 ng/L; HR = 1.57 (95% CI: 1.35, 1.81) for NT-proBNP ≥248.1 pg/mL and HR = 1.19 (95% CI: 1.06, 1.34) for NT-proBNP 137.2-248.0 pg/mL vs. <48.1 pg/mL). The 15-year cumulative incidences of hospitalization with infection were similar for participants with prevalent CVD and participants who did not have prevalent CVD but had hs-cTnT ≥14 ng/L or NT-proBNP ≥248.1 pg/mL. Thus, hs-cTnT and NT-proBNP were independently associated with infection risk. Persons without CVD but with elevated hs-cTnT or NT-proBNP levels should be recognized to have similar infection risks as persons with prevalent CVD.
