Diabetes mellitus is connected with clopidogrel resistance, an independent risk factor of future ischemic events in patients undergoing percutaneous coronary interventions, including stent thrombosis. On-treatment platelet reactivity assessment should be considered especially in clopidogrel-treated DM patients. Platelet function testing might be performed either with nonspecific methods, such as light transmission aggregometry as a golden standard, or with a specific method – VASP (vasodilator stimulated phosphoprotein) phosphorylation assessment. New ADP-receptor blockers – prasugrel and ticagrelor – seem to be more effective for overcoming clopidogrel resistance in diabetic patients. These agents both show rapid and consistent platelet inhibition. Tailored clopidogrel therapy may be considered in selected cases; however, this strategy has lower evidence from clinical trials. The therapeutic goal is to achieve sufficient inhibition of ADP-signaling pathway, which will reduce the risk of future serious ischemic events.

Key words:
ADP-receptor blockers, aggregometry, clopidogrel, clopidogrel resistance, diabetes mellitus, phosphorylation VASP, prasugrel, ticagrelor
