Immune Checkpoint Inhibitor Myocarditis Risk Index Calculator

Immune Checkpoint Inhibitor Myocarditis Risk Index: Explanation and Clinical Context This risk index is derived from a multicenter study involving 748 patients treated with immune checkpoint inhibitors (ICIs). The index incorporates five key factors: presence of active thymoma, cardio-muscular symptoms, low QRS voltage on electrocardiogram, left ventricular ejection fraction (LVEF) <50%, and elevated troponin levels. A higher score correlates with an increased risk of severe myocarditis and related adverse cardiac events.

Clinicians can use this tool to stratify patients and tailor management strategies accordingly.
