Possible (empirical) algorithm for periprocedural (in-hospital early phase) antithrombotic therapy

	Bridging i.v. thrombolysis	No thrombolysis
No permanent stenting	Periprocedural heparin 0–25 U/kg Aspirin 100 mg/day starting after control CT (within 24 h)	Periprocedural heparin 25–40 U/kg Aspirin 100 mg/day starting after control CT (within 24 h)
Stent implanted in acute phase	Periprocedural heparin 20–30 U/kg Aspirin 200–300 mg just prior to stent implantation, followed by 100 mg/day Clopidogrel 75 mg/day starting after control CT (within 24 h)	Periprocedural heparin 25–40 U/kg Aspirin 200–300 mg just prior to stent implantation, followed by 100 mg/day Clopidogrel 75 mg/day starting after control CT (within 24 h)
Deferred stent implantation	Periprocedural heparin 25–40 U/kg Aspirin 200–300 mg just prior to stent implantation, followed by 100 mg/day Clopidogrel 75 mg/day starting just after stenting	Periprocedural heparin 25–40 U/kg Aspirin 200–300 mg just prior to stent implantation, followed by 100 mg/day Clopidogrel 75 mg/day starting just after stenting
