    The study investigates the association between the remnant cholesterol inflammatory index (RCII) and new-onset atrial fibrillation (NOAF) in STEMI patients.

  • 2

    A total of 945 STEMI patients were included, with 79 (8.36%) developing NOAF during hospitalization.

  • 3

    Patients with NOAF exhibited significantly higher levels of RCII, remnant cholesterol (RC), and high-sensitivity C-reactive protein (hs-CRP).

  • 4

    Multivariable logistic regression analysis indicated that RCII, hs-CRP, and RC were independently associated with the occurrence of NOAF.

  • 5

    RCII demonstrated moderate discriminatory ability for identifying NOAF, outperforming RC and hs-CRP alone in ROC curve analysis.
