The new high-sensitivity cardiac troponin T (hs-cTnT) assay seems to provide important prognostic information in patients with stable cardiovascular disease. To understand the merit of hs-cTnT more closely in stable cardiovascular disease, we performed extensive echocardiographic characterization of 57 patients with aortic stenosis and myocardial hypertrophy and related hs-cTnT levels to prognosis and echocardiographic indexes of myocardial structure and function. The hs-cTnT levels were above the assay's detection limit in all patients, correlated with echocardiographic indexes of structure and function, most notably with left ventricular mass, and demonstrated prognostic utility of similar strength as N-terminal pro-B-type natriuretic peptide. In conclusion, these findings indicate that hs-cTnT may provide prognostic information in patients with aortic stenosis, and that left ventricular mass is an important determinant of TnT levels in stable patients as measured by the new highly sensitive assay.
