Prognostic value of left atrial strain analysis using cardiac magnetic resonance feature tracking technology for patients with acute myocarditis.

ABSTRACT:

Background

Acute myocarditis (AM) is induced by multiple factors, and its clinical symptoms and prognosis vary significantly. Existing diagnostic and prognostic assessment methods have certain limitations. Myocardial strain analysis based on cardiac magnetic resonance feature tracking (CMR-FT) can detect myocardial damage in the subclinical stage, but studies on the correlation between left atrial (LA) strain and the prognosis of AM are relatively limited. This study aimed to assess whether impaired LA strain parameters based on CMR-FT-derived techniques can be used to predict AM outcomes.

Methods

A retrospective cohort study was conducted on the clinical and functional parameters, including LA strain, of 91 patients diagnosed with AM between September 2020 and June 2022. Th
