Immune Checkpoint Inhibitors (ICIs)-Related Cardiotoxicity

The growing success of immune checkpoint inhibitors (ICIs) has led to effectively treating several types of cancers. Even though their use has been associated with the development of cardiac adverse effects, which may decrease the overall survival in cancer patients. These cardiac toxicities are thought to be the result of targeting specific checkpoint proteins on normal myocardial cells leading to over stimulation of the immune system as well as secondary downstream off-target effects on normal tissue. Although cardiotoxicities related to immunotherapy are reportedly rare, they can be severe and associated with life-threatening conditions such as fulminant myocarditis, hemodynamic instability, and cardiac arrest. We will review the most commonly reported cardiovascular toxicities associated with ICIs and their management.
