About this study

Official title: Multicenter Retrospective Observational Study to Investigate the Characteristics and Prognosis of Patients With Acute Myocarditis in Korea

In this study, the investigators analyze the clinical characteristics and prognosis of patients with acute myocarditis in South Korea

Read the detailed description

Acute myocarditis refers to a condition in which inflammatory cells infiltrate the heart muscle due to various causes. Until now, there is no clear treatment method for myocarditis itself, and when myocardial function deteriorates or arrhythmia occurs due to myocarditis, it is common to wait for natural recovery while performing general supportive treatment for heart failure.

Through this study, the investigators analyze the factors contributing to the long-term prognosis, myocardial recovery rate, and clinical course of myocarditis. And, the investigators plan to establish an appropriate treatment strategy necessary to increase the survival rate of patients with myocarditis.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Rate of In hospital mortality

    In hospital death by any cause

    Measured: through study completion, an average of 1 year

Secondary outcomes (3)
  1. Rate of all-cause mortality

    Death by any cause during follow-up

    Measured: through study completion, an average of 1 year

  2. Requirement of cardiac replacement therapy

    Left ventricular assist device insertion or heart transplantation during follow-up

    Measured: through study completion, an average of 1 year

  3. Rates of Re-hospitalization due to any cause

    Re-hospitalization due to any cause during follow-up

    Measured: through study completion, an average of 1 year
