Background:This research aimed to explore the correlation between lipid levels and diabetic indices among confirmed patients experiencing myocardial infarction, comparing those with and without type II diabetes mellitus.Methods:A total of 400 individuals experiencing acute myocardial infarction with ST-segment elevation were included in this study. The participants were divided into two groups: those with diabetes mellitus type II and those without. Lipid levels and diabetic indices were assessed, and the relationships between these variables were thoroughly examined.Results:Triglycerides demonstrated positive correlations with fasting blood sugar, while low-density lipoprotein showed positive correlations with insulin levels when assessed across myocardial infarction patients. In the subgroup analysis comparing myocardial infarction patients with and without diabetes mellitus type II, negative correlations emerged between triglycerides and glycosylated hemoglobin (HbA1C), low-density lipoprotein and glycosylated hemoglobin, as well as glycosylated hemoglobin and insulin. Conclusion:Positive associations were observed between triglycerides and fasting blood sugar, as well as between low-density lipoprotein and insulin levels in the overall assessment of myocardial infarction patients. In the subgroup analysis, comparing patients with and without diabetes mellitus type II, inverse relationships were identified between triglycerides and glycosylated hemoglobin (HbA1C), low-density lipoprotein and glycosylated hemoglobin, and glycosylated hemoglobin and insulin.
