The association between HbA1c/C-peptide levels and short-term mortality in patients diagnosed with myocardial infarction

<b>Introduction:</b> In this study, we aimed to investigate the effect of HbA1C/C-peptide ratio on short-term mortality (this period is defined as 30 days after diagnosis) in the patients with myocardial infarction.<b>Materials & Methods:</b> Around 3245 patients who were admitted due to ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction underwent primary percutaneous coronary intervention between October 2020 and 2024 were included in this study.<b>Results:</b> In the receiver operating characteristic analysis, the predictive power of the HCR score for mortality in ST-elevation myocardial infarction patients was determined to be 83% sensitivity and 81% specificity. In non-ST-elevation myocardial infarction, this was determined to be 78% sensitivity and 75% specificity.<b>Conclusion:</b> The HbA1C/C-peptide ratio score can predict poor clinical outcomes early, reducing mortality and morbidity in patients with myocardial infarction.
