One of the leading causes of diabetes-related deaths is myocardial damage, which may be the cause of heart failure in people with type 2 diabetes mellitus. The objective of the research was to look at the impact of coronary failure with kind a pair of type 2 diabetes mellitus. This project aimed to explore the protective impact of oleanolic acid on myocardial damage in type 2 diabetes mellitus and to investigate the connected mechanism. Specific pathogen free grade db/db male mice were elected as model, while the Db/m mice were opted for control. Different doses of drug intervention were performed and the general condition, cardiac function, blood glucose, blood lipids, degree of myocardial injury, and degree of oxidative stress were examined by morphological examination of myocardial tissues, biochemical examination, and gene and protein amount detection. The results showed that lactate dehydrogenase, creatine kinase isoenzyme, total cholesterol, triglycerides and malondialdehyde levels in serum of Db/db mice were increased, while phosphatidylinositol 3 kinase, protein kinase B, glucose transporter 4 expression and superoxide dismutase level in myocardial tissue were decreased. After using oleanolic acid, the serum concentrations of lactate dehydrogenase, creatine kinase isoenzyme, total cholesterol, triglycerides and malondialdehyde were declined in Db/db mice, while phosphatidylinositol 3 kinase, protein kinase B, glucose transporter 4 expression and superoxide dismutase level were rised. The results recommend that oleanolic acid has protective impact on cardiac muscle injury in Db/db mice and conjointly the mechanism could also be correlated with promoting the activation of phosphatidylinositol 3 kinase/protein kinase B/glucose transporter 4 signal transduction.
