Cardiac troponin T associates with left ventricular function and synchrony assessed by CMR in the general population: results from the Akershus Cardiac Examination 1950 Study.

ABSTRACT:

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 C
