  Background and aim Cardiac troponin T (cTnT) is a blood biomarker of myocardial injury that is associated with future adverse cardiovascular events in the general population. Left ventricular (LV) global longitudinal strain (GLS) and mechanical dispersion (MD) are metrics of systolic function and synchrony that can be obtained from cardiac imaging. Studies suggest an association between cTnT and echocardiographically assessed GLS and MD, but it is unknown whether cTnT relates to these metrics when assessed by cardiac magnetic resonance (CMR). We hypothesized that cTnT associates with GLS and with MD assessed by CMR feature tracking (CMR-FT) in the general population. Methods and results cTnT and CMR-FT measurements were performed in 186 community dwellers from the Akershus Cardiac Examination 1950 Study. The participants’ age ranged from 68 to 70 years. Median cTnT concentration was 7.0 ng/L (interquartile interval 5.0–12.6 ng/L), median absolute value of GLS was 17.3% (interquartile interval 15.7–18.8%), and median MD was 80.7 milliseconds (interquartile interval 61.8–105.0 milliseconds). In multivariable linear regression models adjusted for common clinical risk factors of cardiovascular disease, with GLS and MD as outcome and cTnT as the predictor variable of interest, log10 transformed cTnT was significantly associated with both absolute GLS [β-coefficient −1.65, confidence interval (−2.84, −0.46)] and MD [β-coefficient 28.56, confidence interval (12.14, 44.92)]. Conclusion In older adults from the general population, higher cTnT concentrations are associated with worse systolic function and synchrony assessed by CMR-FT LV GLS and MD, adding information about myocardial function to traditional risk factors.
