Myocardial Expression of PD-L1 as a Marker of Poor Prognosis in Immune Checkpoint Inhibitor–Associated Myocarditis | JACC: CardioOncology

Research fellow, Adrian Chen, discusses a multicenter study evaluating myocardial PD‑L1 expression as a prognostic biomarker in immune checkpoint inhibitor–associated myocarditis. The conversation highlights how elevated myocardial PD‑L1 identifies patients at markedly higher risk for early adverse cardiac events and explores its potential role in improving risk stratification and guiding earlier, more aggressive therapy in this high‑risk population.
