BACKGROUND: High sensitivity troponin T (hsTnT) assays enable us to detect chronic heart failure (CHF). Adult congenital heart disease (ACHD) patients are classified as being in at least stage B of CHF. The purpose of the study was to assess hsTnT levels in ACHD patients and determine its clinical significance. METHODS: This is a prospective cross-sectional study. We assessed hsTnT in 131 ACHD patients and in 30 healthy controls. All ACHD patients underwent routine clinical and echocardiographic evaluation and had hsTnT and N-terminal brain natriuretic peptide (NT-pro-BNP) level measurements. RESULTS: The cut-off value defining an abnormal hsTnT level was established as >0.005 ng/mL. 35.1% (n=46) of ACHD patients had abnormal hsTnT compared to 6.7% (n=2) of healthy controls (p=0.002). The prevalence of elevated hsTnT did not differ between simple and complex and between non-cyanotic and cyanotic congenital heart disease (CHD). The sensitivity and specificity of hsTnT for the detection of moderate or severe (significant) systemic ventricular dysfunction was 78.6% and 69.8%, respectively (OR 8.49; CI 95% 2.23-32.30; p<0,0001) whereas for significant pulmonary ventricular dysfunction it was 66.7% and 68.2%, respectively (OR 4.29; CI 95% 1.56-11.79; p=0.003). In multivariate logistic regression models elevated hsTnT, but not NT-pro-BNP, was independently associated with both significant systemic ventricular dysfunction (p=0.004) and significant pulmonary ventricular dysfunction (p=0.011). CONCLUSIONS: A troponin leak is observed in a substantial number of ACHD patients and is associated with significant systemic and pulmonary ventricular impairment. Compared to NT-pro-BNP, hsTnT is a more specific independent predictor of ventricular dysfunction in ACHD.
