Clopidogrel resistance in diabetic patient with acute myocardial infarction due to stent thrombosis.
Stent thrombosis is a morbid complication after percutaneous coronary intervention. Dual antiplatelet therapy significantly reduces stent thrombosis risk and forms currently the basis in acute ST elevation myocardial infarction pharmacologic treatment. The introduction of clopidogrel has made a major advance in the acute coronary syndrome treatment. ⋯ We report a case of diabetic patient in whom myocardial reinfarction due to stent thrombosis developed. Clopidogrel resistance was detected in this patient using light transmission aggregometry and vasodilator-stimulated phosphoprotein phosphorylation assessment. After prasugrel administration, no other ischemic event occurred, and patient was released to outpatient care in good general condition.
