Implication

Narrative review reveals lethal cardiac toxicity and rapid circulatory collapse in cancer immunotherapy, highlighting the urgent need for early diagnosis and predictive biomarkers.

Key Points

Examine the immune mechanisms, clinical presentations, and diagnostic challenges associated with myocarditis induced by immune checkpoint inhibitor therapies.
Synthesized preclinical evidence from genetically engineered mouse models evaluating CTLA-4 and PD-1 regulation of cardiac peripheral immune tolerance.
Reviewed documented clinical cases, diagnostic approaches, and progression patterns in cancer patients developing immune checkpoint inhibitor-induced myocarditis.
Demonstrates that CTLA-4 signaling terminates primary proliferation while PD-1 restrains autoreactive T cells within peripheral cardiac tissue to prevent autoimmunity.
Identifies that checkpoint inhibitor-related myocarditis often features early-onset, fulminant progression to cardiogenic shock and lethal ventricular arrhythmias, especially under combination regimens.
Highlights diagnostic complexity caused by heterogeneous and nonspecific symptoms, emphasizing the clinical need for rapid intervention and predictive risk biomarkers.
