INTRODUCTION: Immune checkpoint inhibitor(ICI) induced cardiac immune related adverse events are challenging to study; Leveraging large data bases like TriNetX global health network may provide needed insights.
METHODS: We performed a retrospective cohort study including patients diagnosed neoplasm and 18 and older when receiving ICI therapy from 1/1/2011 to 12/31/2022. Queried ICD 9/10 codes identified patients experiencing myocarditis, pericarditis, pericardial effusion, and cardiac tamponade within 1 year of ICI initiation. Survival analyses compared one-year overall survival (OS) of patients experiencing cardiac irAEs against propensity score matched populations not experiencing them.
RESULTS: In 88,928 identified ICI patients, the incidence of myocarditis(0.48%), pericarditis(0.22%), and cardiac tamponade(0.47%) were less than 1% while pericardial effusion occurred in 4.71% of patients. Hazard ratios (HRs) were significantly higher in all cardiac irAE groups: myocarditis (HR:1.26, 95% CI:1.04-1.54, p = 0.02), pericarditis (HR:1.36, 95% CI:1.02-1.82, p = 0.04), pericardial effusion (HR:1.49, 95% CI:1.39-1.59, p < 0.0001), cardiac tamponade (HR:2.15, 95% CI:1.79-2.57, p < 0.0001), and overall pericardial disease (HR:1.46, 95% CI:1.37-1.56, p < 0.0001). There was no significant difference in OS between myocarditis and pericarditis or overall pericardial diseases.
DISCUSSION/CONCLUSION: Utilizing a uniquely large cohort of ICI patients, this study further shows the rarity of cardiac inflammatory irAEs and highlights their significant impact on patient survival.
