Progress in Diagnosis and Treatment of Immune Checkpoint Inhibitor-Associated Cardiotoxicity

Immune checkpoint inhibitors (ICIs) are a new type of broad-spectrum antitumor drugs, which mainly include cytotoxic T-lymphocyte-associated protein-4 (CTLA-4) inhibitors, programmed cell death protein-1 (PD-1) and its ligand PD-L1 inhibitors. Since 2011, ICIs have been approved for more than 20 kinds of malignant tumors.
