The aim of this study is to collect clinical data and biological specimens from patients with myocarditis and construct a predictive model for the prognosis of myocarditis.

The aim of this study is to retrospectively and prospectively collect clinical data and biological specimens from patients with myocarditis who meet the inclusion and exclusion criteria. General molecular biology analysis, genome sequencing, transcriptome sequencing, methylation sequencing, metabolomics analysis, proteomics analysis, genome-wide chromosome conformation capture and other techniques are used to construct a prognosis prediction model for myocarditis.

Inclusion Criteria:

• All patients should meet the diagnostic criteria for myocarditis
• Patients who are regularly followed up at the corresponding cardiovascular center

Exclusion Criteria:

• Age <3 years or >80 years
• Pregnant or lactating women
• The patient refused to sign the informed consent and refused to participate in the study
• None of the above is consistent, but the patient cannot sign the informed consent temporarily due to coma and other reasons, and there is no legal representative to sign it instead. Depending on the condition, the patient may not wake up to sign the informed consent

All hospitalized patients who meet the diagnostic criteria for myocarditis and undergo regular follow-up at the corresponding cardiovascular center are included in the study.
