Relationship Between Glycosylated Hemoglobin Concentration and Prognosis of Acute ST-Segment Elevation Myocardial Infarction in Non-Diabetic Patients.

OBJECTIVE

To investigate the relationship between glycosylated hemoglobin (HbA1c) concentration at admission and the prognosis of acute ST-segment elevation myocardial infarction (STEMI) in non-diabetic patients.

METHODS

A total of 142 non-diabetic patients with acute STEMI who underwent emergency percutaneous coronary intervention (PCI) in our hospital between January 2023 and December 2024 were enrolled in this study. HbA1c levels and baseline data for all patients were obtained at admission. According to the HbA1c level, patients were divided into a normal blood glucose level group (group A, HbA1c & lt; 5.7%, N = 57) and a pre-diabetic group (group B, 5.7% ≤ HbA1c ≤ 6.4%, N = 85). The occurrence of major cardiovascular events (MACE) was compared between the two groups after PCI during one-year follow-up.

RESULTS

The levels of serum FPG, BNP and the number of patients with multivessel diseases in group B were higher than those in group A (all p < 0.05). The LVEF in group B was significantly lower than in Group A (P = 0. 017). The total incidence of major cardiovascular events (MACE) within 1 year after PCI was significantly higher in group B than in group A (P = 0. 047). In addition, the risk of MACE in group B was 4.98 times higher than that in group A.

CONCLUSION

HbA1c can be used as an independent predictor of MACE in non-diabetic STEMI patients. The control of blood glucose levels in pre-diabetic patients with STEMI should be given high emphasis to improve prognosis after PCI.
