A case study of myopericarditis due to immune checkpoint inhibitor therapy: Proposed surveillance and management

Immune checkpoint inhibitor (ICI) therapy is a treatment modality used in many types of cancer. Immune-related adverse events are relatively common. Cardiovascular adverse events are uncommon, but carry a high mortality rate of 25-50%. They require cessation of therapy. There is currently no universal screening before initiation of ICI therapy to identify patients with cardiovascular risk. There is also no ongoing screening to identify myocarditis and treatment is driven by symptoms. This article provides a case study of a patient who developed myopericarditis and the patient's clinical course. Furthermore, it proposes surveillance for patients before and during ICI therapy to swiftly identify potential cases of myocarditis. There is currently no universal baseline screening for cardiovascular risk in patients planned for ICI therapy. A proposed baseline cardiac evaluation, as well as scheduled surveillance therapy, is outlined in this article. With further education and training, immune-related cardiac adverse events may be more promptly detected, leading to better patient outcomes.
