Background information: The current study looked at the potential cardioprotective benefits of GLP1 and SGLT2i against diabetic cardiomyopathy (DCM) in type 2 diabetic rats, as well as the mechanisms behind them. The existence of heart failure in the absence of coronary artery disease is referred to as DCM.

 Methods: Forty-two male Sprague Dawley rats were randomized into four equal groups at random; a) DM+ GLP1, as DM group with GLP1 analogue (liraglutide) at a dose of 75 g/kg for 4 weeks, and DM+ SGLT2i: as DM group with SGLT2 inhibitor (dapagliflozin) at a dose of 1 mg/kg for 4 weeks. Serum blood glucose, HOMA-IR, insulin, and cardiac enzymes (LDH, CK-MB) were all tested at the end of the four-week treatment.

Myocardial oxidative stress markers (MDA, GSH, and CAT) as well as norepinephrine (NE), myocardial fibrosis, and the expression of caspase-3, TGF-, TNF-, and tyrosine hydroxylase (TH) in myocardial tissues were all assessed. As a result, T2DM resulted in a considerable increase in blood sugar levels. (p 0.05) serum glucose, HOMA-IR, serum CK-MB, and LDH In addition, DM resulted in severe myocardial damage and fibrosis, as well as an increase in myocardial MDA, NE, and upregulation of myocardial caspase-3, TNF, TGF, and TH, as well as a substantial drop in serum insulin, myocardial GSH, and CAT (p0.05). All examined indicators improved significantly (p 0.05) after administration of either GLP1 analog or SGLT2i. Conclusion: We found that both GLP1 and SGLT2i had cardioprotective effects against DCM in T2DM, with SGLT2i having the upper hand. This could be related to fibrosis, oxidative stress, apoptosis (caspase-3), sympathetic nerve activity, and other factors.
