Background: The influence of different viral infections in
patients with myocarditis is unknown. Myocarditis is an inflammatory disease of
heart muscle that is commonly caused by viruses. The impact of different viral
infections in patients with myocarditis is unknown. Methods: We
conducted a retrospective cohort study using data between 2016–2020 in the
National Inpatient Sample in the USA to evaluate admissions with myocarditis and
concomitant viral infection. The outcomes of in-hospital mortality, length of
stay (LoS), and cost, among patients hospitalized for myocarditis was evaluated.
Results: A total of 27,050 hospital admissions for myocarditis were
included and 6750 (25.0%) had a co-diagnosis of viral infection. Patients with
myocarditis and viral infection had significantly higher mortality compared to
those without viral infection (23.6% vs. 4.4%, p
