A significant proportion of patients with acute myocarditis experience sudden cardiac
death presumably due to cardiac arrhythmia. In this study, we explore the burden,
the predictors of arrhythmia in acute myocarditis and the association between arrhythmias
and adverse in-hospital outcomes. After evaluating the frequency of various tachyarrhythmias
and bradyarrhythmia in myocarditis population, we built a logistic model to determine
the independent predictors of arrhythmias in myocarditis and a 1:1 propensity-matched
analysis to examine the impact of arrhythmias. Overall, cardiac arrhythmias were identified
in 33.71% of the hospitalized myocarditis cases. Ventricular tachycardia and atrial
fibrillation were most common arrhythmias. There were increased odds of in-hospital
mortality, cardiogenic shock, use of mechanical circulatory support, pacemaker implantation,
and nonroutine hospital discharges in the arrhythmia cohorts. Length of stay and cost
of hospitalization were also significantly higher. A significant proportion of patients
with myocarditis have cardiac arrhythmias. As the occurrence of arrhythmias in myocarditis
is associated with worse outcomes, it may be important to risk stratify patient to
identify those who will benefit from early intervention.
