Successful Therapy With Ticagrelor in Three-Vessel Stent Thrombosis Related to Clopidogrel Resistance.

A 65-year-old man developed 3-vessel stent thrombosis after percutaneous coronary intervention with aspirin and clopidogrel. Platelet tests revealed clopidogrel resistance, which resolved after changing clopidogrel to ticagrelor. Although routine platelet tests after stenting are not recommended, these tests may be considered to identify the cause of stent thrombosis and modify antiplatelet therapy.
