Background: Fatal clozapine-induced myocarditis has not been investigated systematically. We describe the
clinical course of 10 fatal cases of myocarditis with clozapine and identify factors associated with fatality.
Methods: Cases of myocarditis were documented from the patient's medical records and fatal cases also from
Results: The fatal cases of myocarditis occurred 1996–2009 and were diagnosed at autopsy. Before death,three had no symptoms of illness and only three had cardiac-speciﬁc diagnostic results. None was
investigated by cardiac imaging techniques, and in none was myocarditis suspected before death. Duration of
clozapine for the fatal cases was 14–33 days with an outlier at 4.5 months. Only 3 cases had signiﬁcant
Comparison of these ten cases with 66 non-fatal cases indicated no signiﬁcant difference in gender, age,
smoking status, dose at onset or concomitant sodium valproate. However, obesity (BMI N 30 kg/m2) was
signiﬁcantly more frequent among fatal than non-fatal cases (60% vs 26%; p b 0.03) and duration of clozapinewas signiﬁcantly longer for fatal cases (20.8 vs 17.0 days; p b 0.006), after exclusion of one outlier. Creatinekinase (CK) N 1000 U/L was also associated with death (p = 0.0004).
Conclusions: Routine monitoring for myocarditis for the ﬁrst 4 weeks of clozapine, and discontinuation ofclozapine in the presence of evidence consistent with myocarditis may assist to prevent fatalities occurringfrom early-onset myocarditis. Investigation by cardiac imaging will give a measure of severity and need forintervention. Obesity may increase the risk of mortality and CK N 1000 U/L may indicate life-threateningillness.
