“…This systemic release of cytokines, characterized by increased IL-2, IL-6, IL-10, GCSF, IFN-γ, MCP-1, MIP-1-α, and TNF-α, likely contributes to cardiac injury in a situation analogous to cardiotoxicity in the setting of chimeric antigen receptor (CAR)-T cell therapy. A prior study demonstrated that cardiac injury and cardiovascular events in the form of elevated troponin and left ventricular systolic dysfunction are common post-CAR-T; in a cohort of 137 patients with post-CAR-T cytokine release syndrome (CRS), 21% had elevated troponin and 12% developed cardiovascular events including cardiac arrest, decompensated heart failure, and arrhythmias [65]. Notably in this study, a shorter time from CRS onset to the administration of the IL-6 inhibitor tocilizumab was associated with a lower rate of cardiovascular events [65].…”
