Myocardial Vasculitis Associated With the Immune Checkpoint Inhibitor Pembrolizumab
Abstract
Recent developments in immune checkpoint inhibitors (ICIs) have provided new treatment strategies for advanced cancer. However, ICIs lead to an imbalance between T cell–mediated inflammatory responses and immune tolerance in the myocardium. Here we report the first case that implicates the contribution of ICI-induced vasculitis to myocardial injury. (Level of Difficulty: Intermediate.)
