Objective To investigate the risk of myocarditis caused by immune checkpoint inhibitors (ICI). Methods The adverse reaction (ADR) reports on myocarditis caused by atelizumab, duvalizumab, pabolizumab, and navulizumab were downloaded from the FDA Adverse Event Reporting System (FAERS) from January 1, 2014 to September 30, 2022. The relevant analysis was conducted on the gender, age, medication dosage, and occurrence time of ICI related myocarditis patients. Results A total of 1 892 reports of myocarditis induced by ICI were included. The proportion of myocarditis caused by ICI was higher in males than in females (1.9∶1). The incidence of myocarditis in patients with basic diseases such as diabetes and heart disease, and in the age group 65-75 was relatively high. The incidence of myocarditis caused by navulizumab was high within 30 days with the use of conventional doses, and that of the other three drugs were high within 31 to 90 days. And the incidence of myocarditis is higher when used in combination than when used alone. Conclusion Different varieties of ICI can lead to the occurrence of myocarditis, and male, elderly, underlying diseases, and combination therapy may be risk factors for myocarditis caused by ICI.
