Association between high-sensitivity cardiac troponin T and future cardiovascular incidence in a general Japanese population: Results from the Tohoku Medical Megabank Project

AbstractPurpose: Elevation of high-sensitivity cardiac troponin T (hs-cTnT) is associated with an increased risk of cardiovascular disease (CVD). This study determined whether hs-cTnT was detectable with N-terminal pro-b-type natriuretic peptide (NT-proBNP) and related to CV risk factors in a general Japanese population.Materials and methods: The Tohoku Medical Megabank Organization pooled individual participant data for a population-based cohort study in the Iwate prefecture (n = 30,193, age = 60.2 ± 11.5 year).Results: Hs-cTnT levels were higher in participants with hypertension, diabetes mellitus than in participants without these conditions (all ps < 0.001). Logistic regression analysis demonstrated that NT-proBNP was strongly associated with elevation of hs-cTnT (OR = 3.35, 95% CI = 2.90–3.89, p < 0.001). The receiver operating characteristic curve analysis showed that hs-cTnT was one of useful biomarker for the differentiation of high risk for CVD (the Suita score ≥ 56) from a general population.
