Over the last two decades, clinical trials have indicated that DM patients with CAD have poorer cardiac outcomes than non-diabetic patients with CAD.

However, since the publication of the FREEDOM trial, much has changed both in percutaneous coronary intervention (PCI) technology, as well as in the management of diabetes. This review provides insights into advancements in stent technology, enhanced patient management strategies, improved clinical outcomes with newer hypoglycaemic agents, current approaches to antiplatelet therapy, and advances in lipid management in diabetic patients. The influence of patient-specific factors such as comorbidities and anatomical complexities on treatment decisions in diabetic patients with MVD is also discussed.

The tertiary objective is to compare the efficacy and safety of ticagrelor versus prasugrel in diabetic patients with MVD.
