High-sensitivity cardiac troponin serving as a useful marker for the early recognition of relapse of isolated cardiac sarcoidosis: a case report.

This case highlights the potential of hs-cTnI to serve as a serum biomarker for monitoring disease activity and response to immunosuppressive therapy in patients with cardiac sarcoidosis. The hs-cTnI could be a highly sensitive and cost-effective biomarker reflecting the inflammatory status of cardiac sarcoidosis.
