BACKGROUND: We aimed to investigate whether high-sensitive cardiac troponin T (hs-cTnT) is associated with all-cause and cardiovascular mortality in stable type 2 diabetes (T2D) outpatients treated in primary care.

METHODS: Cardiac troponin T was measured with a high-sensitive assay at baseline in patients with T2D participating in the observational ZODIAC study. Cox proportional hazards models were used to investigate the relationship between hs-cTnT and mortality with adjustment for selected confounders. Risk prediction capabilities of hs-cTnT were assessed with Harrell C statistics.

RESULTS: Complete baseline data were available for 1,133 patients. During median follow-up of 11 (7-14) years, 513 (45%) patients died, of which 218 (42%) died of cardiovascular causes. Of the patients with undetectable hs-cTnT levels (<3 ng/L), only 23% died, compared with 58% with low detectable levels (3-14 ng/L) and 84% with raised levels (≥14 ng/L). Natural log hs-cTnT was significantly associated with all-cause mortality (hazard ratio 1.30, 95% CI 1.19-1.42) and cardiovascular mortality (hazard ratio 1.33, 95% CI 1.15-1.53), independent of potential confounders. The Harrell C statistic for the crude model of hs-cTnT was 0.72 (95% CI 0.70-0.75) for all-cause mortality and 0.74 (95% CI 0.71-0.77) for cardiovascular mortality.

CONCLUSIONS: Higher levels of hs-cTnT are associated with mortality in stable outpatients with T2D. The high crude Harrell C values and the excellent prognosis of patients with undetectable levels illustrate the strength of hs-cTnT as a potential marker for mortality.
