Abstract
The conventional use of high-sensitivity troponins (hs-troponins) is for diagnosing myocardial infarction however they also have a role in chronic disease management. This pilot study assessed the relationship of hs-troponins with echocardiographic markers of left ventricular hypertrophy (LVH) and structural heart disease (SHD). Patients undergoing computer gomography (CT) coronary angiogram for low-intermediate risk chest pain and healthy volunteers were recruited. Hs-troponins Singulex I, Abbott I and Roche T and N-terminal pro-brain natriuretic peptide (NT-proBNP) were evaluated in relation to SHD parameters including left ventricular hypertrophy (LVHEcho) and left atrial enlargement (LAEEcho) on echocardiography. 78 subjects who underwent echocardiography were included in this study. C-statistics (95% confidence interval) of the four biomarkers for predicting LVHEcho were 0.84 (0.72–0.92), 0.84 (0.73–0.92), 0.75 (0.63–0.85) and 0.62 (0.49–0.74); for LAEEcho 0.74 (0.6–0.85), 0.78 (0.66–0.88), 0.55 (0.42–0.67) and 0.68 (0.62–0.85); and composite SHD 0.79 (0.66–0.88), 0.87 (0.75–0.94), 0.62 (0.49–0.73) and 0.74 (0.62–0.84) respectively. Optimal cut points for SHD were >1.2 ng/L, >1.6 ng/L, >8 ng/L and >18 pmol/L respectively. These results advocate the potential role of hs-troponins as screening tools for structural heart disease with theranostic implications.
