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

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. 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. 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. The HbA1C/C-peptide ratio score can predict poor clinical outcomes early, reducing mortality and morbidity in patients with myocardial infarction.
