Evaluation of Cardiac Adverse Events with Nivolumab Using a Japanese Real-World Database.

This study focused on cardiac AEs caused by nivolumab as post-marketing AEs. Myocarditis and pericardial effusion have been associated with some fatal cases after administration of nivolumab. Patients should be monitored for signs of onset for these AEs, not only at the start of administration, but also over an extended period after nivolumab administration.
