Objective:

To investigate the combined prognostic value of post-PCI AMR and HbA1c levels for MACCEs in patients with STEMI and T2DM.

Approach:
    Key Findings:
    • HbA1c (HR = 1.403) and AMR (HR = 1.213) were independently associated with MACCEs.
    • Patients with HbA1c ≥6.5% and AMR ≥250.5 mmHg·s/m had the highest risk of MACCEs (HR = 6.903).
    • Nonlinear relationships were observed between MACCEs and both HbA1c and AMR levels.
    Interpretation:

    Limitations:
    • Retrospective design may introduce selection bias.
    • Limited generalizability due to specific inclusion criteria.
    Conclusion:
