Neutrophil-to-lymphocyte ratio for risk stratification in acute myocarditis across the left ventricular ejection fraction spectrum.

ABSTRACT:

Aims

Acute myocarditis (AM) is a heterogeneous clinical condition. Several classification models have been proposed to predict adverse clinical outcomes, but risk stratification remains challenging, particularly for patients presenting with preserved left ventricular ejection fraction (LVEF). Neutrophil-to-lymphocyte ratio (NLR) is a useful tool for risk stratification in patients with AM. This study aimed to compare the predictive accuracy of available risk stratification models, including NLR, for identifying patients with AM at increased risk of adverse events.

Methods and results

The study included 1150 patients with biopsy- or cardiac magnetic resonance (CMR)-proven AM from 10 hospitals in six countries. Baseline clinical, laboratory, echocardiographic and CMR data, and
