Background: High-sensitive (hs) troponin T and I assays as well as ultrasensitive (us) troponin I enable measurement of troponins in 65% to 98% of the general population. We prospectively investigated whether increased concentrations of us-troponin I are associated with an increased risk of coronary heart disease (CHD) after controlling for traditional risk factors. Methods: We conducted a population-based case cohort study in middle-aged healthy men and women within the MONICA/KORA Augsburg studies. Serum levels of us-troponin I (Single Molecule Counting technology, Singulex) were available in 2,745 men and women including 803 incident CHD cases. Geometric mean us-troponin I was 1.56 ng/L. Mean (SD) follow-up was 16.0 (5.8) years. Results: Baseline concentrations of us-troponin I were higher in cases compared to non-cases (geometric mean 2.56 vs. 1.49 ng/L, p<0.0001) and in men compared to women (geometric mean 1.93 vs. 1.27 ng/L, p<0.0001). After adjustment for variables of the Framingham Risk Score, the hazard ratio (HR) with 95% confidence interval (CI) for a CHD event in the top quartile compared to the bottom quartile was 2.76 (95% CI, 1.87-4.09). After additional adjustment for alcohol intake, physical activity, and body mass index, hazard ratios remained essentially unchanged. Conclusions: Troponin I measured by an us-assay was detectable in almost all subjects. This is the first population-based prospective study with long-term follow-up showing that even modestly increased concentrations of us troponin I are strongly associated with incident CHD independently of a variety of traditional risk factors.
