Successful Management of Fulminant Immune Checkpoint Inhibitor–Associated Myocarditis Amid Corticosteroid Constraints and Clinical-Biomarker Dissociation

Rebound elevation of troponin T levels may indicate myocardial remodeling rather than active injury, supporting corticosteroid tapering in clinically stable patients. In patients with ICI-associated myocarditis and contraindications to corticosteroids, early steroid tapering combined with alternative immunosuppressive therapy may still achieve favorable outcomes.
