"Emerging clinical approaches in diabetic cardiomyopathy: insights from clinical trials and future directions"

We aim to explore the potential of diverse treatments, including perhexiline, calcium channel blockers, anti-hypertensives, PDE5 inhibitors, anti-anginal drugs, aldose reductase inhibitors, and SGLT-2 inhibitors, supported by clinical evidence. Additionally, this review seeks to identify novel therapeutic targets and future avenues for improving cardiovascular outcomes in diabetic populations.

We performed a comprehensive literature review of English-language studies across multiple electronic databases, such as PubMed, ScienceDirect, Scopus, and Google Scholar, focusing on clinical trials. The search utilized keywords including 'Anti-hyperglycaemic drug,' 'Diabetic cardiomyopathy,' 'DPP-4 inhibitors,' 'GLP-1 receptor agonists,' 'Heart failure,' and 'SGLT-2 inhibitors.'

We assessed clinical investigations in the treatment of cardiomyopathy and diabetes mellitus (DM) that are enhancing our understanding through trials evaluating the Polypill, Perhexiline, Eplerenone, IMB-1018972, AT-001, tadalafil, and dapagliflozin inhibitors. The development of new targeted interventions is of paramount importance due to the overlooked early symptoms, the complexity of the cellular and molecular pathways involved, and the absence of effective drug therapies.

Pharmacological treatments like GLP-1 agonists, SGLT-2 inhibitors, NHE-1, NHE-3, and PPAR-γ agonists show promise for treating DCM. These treatments improve myocardial glucose absorption, address dysregulated glucose and lipid metabolism, and lower heart failure and cardiovascular events. Further research is needed to confirm effectiveness and safety.
