Key result

Steroids normalize eosinophil markers and resolve clinical features in eosinophilic myocarditis.

  • n=1

Why the study?

Eosinophilia may cause cardiac damage, and the role of eosinophil degranulation and serum ECP as diagnostic and treatment indicators in eosinophilic myocarditis needed confirmation.

Overview

Single case links high ECP to eosinophilic myocarditis; hypothesis-generating for biomarker role, needs prospective validation.

Structured PICO

P
Population
A 27-year-old woman with NYHA class III congestive heart failure and eosinophilic myocarditis.
I
Intervention
Steroid treatment
O
Outcome
Normalization of total eosinophil count and serum ECP, and improvement in clinical features

Serum eosinophil cationic protein (ECP) levels may serve as a reliable biomarker for the diagnosis and treatment monitoring of eosinophilic myocarditis.

Cite This Study

Arima et al. (1999) conducted a case report in Eosinophilic myocarditis (n=1). Steroid treatment was evaluated on Clinical features, total eosinophil count, and serum ECP. Steroid treatment normalized total eosinophil count and serum ECP levels, leading to satisfactory improvement in clinical features of eosinophilic myocarditis.
