The authors carried out a complete review, expanding the results and perspectives obtained from clinical trials to include the real-life results of patients.
Myocarditis is the most common adverse cardiovascular event associated with ICIs (45%), with a rate of fulminant myocarditis of 15%. The mortality rate is 50%, while the mortality rate associated with pericardial disease or vasculitis is 21% and 6%, respectively. Takosubo syndrome, arrhythmias and vasculitis are other important cardiovascular events.1 Despite being uncommon, they are also serious adverse events.
