BACKGROUND: The prognostic utility of high-sensitivity cardiac troponin T (hs-cTnT) on clinical outcomes in cardiac sarcoidosis (CS) remains unknown, so we evaluated hs-cTnT in the chronic phase of CS.
METHODS AND RESULTS: We enrolled 92 consecutive patients with CS in the chronic phase after medical therapies. Patients were divided into 2 groups according to hs-cTnT level: 0.014 ng/mL: high hs-cTnT (n=37); normal hs-cTnT (n=55). The primary endpoint was cardiac death and the secondary endpoint was cardiac death, ventricular tachyarrhythmias, or hospitalization for heart failure. The mean age of patients was 63±11 years, and 75 received steroid treatment. During a median follow-up of 63 months, there were 9 cardiac deaths: 7 (19%) patients with high hs-cTnT and 2 (4%) patients with normal hs-cTnT. The rate of cardiac death was higher in patients with high hs-cTnT than in those with normal hs-cTnT (log-rank, P<0.01). Cox proportional hazard analysis showed that hs-cTnT was an independent predictor of cardiac death. The events rate was higher in patients with high hs-cTnT than in those with normal hs-cTnT (log-rank, P<0.01): cardiac death, ventricular tachyarrhythmias or hospitalization for heart failure occurred in 24 (65%) patients with high hs-cTnT and 11 (20%) patients with normal hs-cTnT.
CONCLUSIONS: Elevated hs-cTnT was linked with adverse outcomes in CS patients, suggesting it is an effective prognostic biomarker.
