FIBRINOLYTIC THERAPY (choose one):

Reteplase 10 U IV over 2 minutes, repeat after 30 minutes

or

Tenecteplase 30-50 mg IV over 5 seconds, based on weight:

- 30 mg for weight <60 kg

- 35 mg for 60-69 kg

- 40 mg for 70-79 kg

- 45 mg for 80-89 kg

- 50 mg for ≥90 kg

or

Streptokinase 1.5 MU IV over 30-60 minutes

ANTICOAGULANT THERAPY (choose one with fibrinolytics):

Unfractionated Heparin: 60 U/kg IV bolus (maximum 4000 U), followed by IV infusion of 12 U/kg/h (maximum 1000 U/h) initially, adjusted to maintain goal aPTT 1.5 to 2.0 times control (approximately 50 to 70 s); check aPTT in 6 h and adjust heparin as indicated. When using a fibrinolytic, use Unfractionated Heparin Dosing Chart. Note: Regimens other than UFH are recommended if anticoagulant therapy is given for more than 48 hours because of the risk of heparin-induced thrombocytopenia with prolonged UFH treatment (see appendix for titration nomogram)

or

Enoxaparin (provided the serum creatinine is <2.5 mg/dL in men and 2.0 mg/dL in women):

- Patients <75 years of age: 30 mg IV bolus, followed 15 min later by 1 mg/kg SC q12h (if CrCl <30 mL/min, give 1 mg/kg every 24 h). Continue for at least 48 hours, and preferably for the duration of hospitalization, up to 8 days.

- Patients ≥75 years of age: No bolus; 0.75 mg/kg SC q12h. Continue for at least 48 hours, and preferably for the duration of hospitalization, up to 8 days.

or

Fondaparinux 2.5 mg IV initially, followed by 2.5 mg SC once daily (avoid if CrCl <30 mL/min). Continue for at least 48 hours, and preferably for the duration of hospitalization, up to 8 days.

For patients treated initially with fondaparinux who later undergo PCI, administer additional IV treatment with an anticoagulant possessing anti-IIa activity (such as UFH or bivalirudin), taking into account whether GP IIb/IIIa inhibitors have been administered. Note: Because of the risk of catheter thrombosis, fondaparinux should not be used as the sole anticoagulant to support PCI.

ANTIPLATELET THERAPY

Clopidogrel 300 mg po loading dose if age <75 years
(75 mg po loading dose if age ≥75 years)

ASSESS FOR REPERFUSION

ECG 60 minutes after initial bolus of fibrinolytic.

Assess for reperfusion based on angina intensity, ST resolution on 60-minute ECG and/or hypotension.

Cardiology consultation, if possible reperfusion failure

Call Dr. __________________________________________________________________

Physician/NP/PA Signature: _________________________ Date: _______ Time: _______

High risk (recommend early transfer <6 hours for PCI)

Low risk (recommend admission to CCU; monitor for ischemia)

If high risk:

Transfer for PCI

Initiate preparatory antithrombotic (anticoagulant plus antiplatelet)

Anticoagulant: _________________________ at _______________________

Antiplatelet: __________________________ at _______________________

It is reasonable for high-risk patients who receive fibrinolytic therapy as primary reperfusion therapy at a non–PCI-capable facility to be transferred as soon as possible to a PCI-capable facility where PCI can be performed either when needed or as a pharmacoinvasive strategy. Consideration should be given to initiating a preparatory antithrombotic (anticoagulant plus antiplatelet) regimen before and during patient transfer to the catheterization laboratory (Class IIa, LOE: B).b

Patients who are not at high risk who receive fibrinolytic therapy as primary reperfusion therapy at a non–PCI-capable facility may be considered for transfer as soon as possible to a PCI-capable facility where PCI can be performed either when needed or as a pharmacoinvasive strategy. Consideration should be given to initiating a preparatory antithrombotic (anticoagulant plus antiplatelet) regimen before and during patient transfer to the catheterization laboratory (Class IIb, LOE: C).b

Adapted with permission from Kushner FG, et al. J Am Coll Cardiol. 2009;54(23):2205-2241.

Note: A planned perfusion strategy using full-dose fibrinolytic therapy followed by immediate PCI may be harmful and is not recommended.

ANTIPLATELET THERAPY (choose one):

Clopidogrel 300-600 mg po loading dose

or

Prasugrel 60 mg po loading doseb,c

and/or

GP IIb/IIIa inhibitor

GLYCOPROTEIN IIB/IIIA INHIBITOR THERAPY (choose one):

Abciximab 0.25 mg/kg IV bolus, followed by IV infusion of 0.125 µg/kg/min (to a maximum of 10 μg/min). Continue for 12 hours.

or

Tirofiban 25 µg/kg IV bolus, followed by IV infusion at 0.15 µg/kg/min. Continue for
18 to 24 hours.

or

Eptifibatide 180 µg/kg IV bolus x 2, 10 min apart, followed by IV infusion of 2.0 µg/kg/min, reduce to 1.0 µg/kg/min if CrCl <50 mL/min. Continue until hospital discharge or for 12 to 18 hours.

It is reasonable to start treatment with glycoprotein IIb/IIIa receptor antagonists (abciximab [Class IIa, LOE: A], tirofiban [Class IIa, LOE: B], or eptifibatide [Class IIa, LOE: B]) at the time of primary PCI (with or without stenting) in selected patients with STEMI.b


ANTICOAGULANT THERAPY (choose one):

Unfractionated Heparin (for at least 48 hours) 60 U/kg IV bolus (not to exceed 4000 U), followed by IV infusion of 12 U/kg/h (not to exceed 1000 U/h) to achieve goal aPTT 1.5 to 2.0 times control (approximately 50 to 70 s). Target ACT in catheterization lab: 200-250 sec if concomitant GP IIb/IIIa inhibitor therapy, 250-300 sec if no concomitant GP IIb/IIIa inhibitor therapy; administer additional boluses to achieve target ACT if measured values below recommended ranges (see appendix for dosing)

or

Enoxaparin 30 mg IV, followed by 1 mg/kg SC q12h, first dose 15 minutes after bolus (if age >75 years, give 0.75 mg/kg every 12 hours with no bolus; if CrCl <30 mL/min, give 1 mg/kg every 24 h after bolus). If the last SC dose was given less than 8 hours prior to PCI, no additional enoxaparin required; if last SC was given 8 to 12 hours earlier or never given, an IV dose of 0.3 mg/kg of enoxaparin should be given. Discontinue after completion of the PCI procedure, unless continued anticoagulation is indicated. Enoxaparin can be used to support PCI after fibrinolysis; no additional anticoagulant is needed.

or

Bivalirudin 0.75 mg/kg IV bolus, followed by infusion of 1.75 mg/kg/h. If UFH was given previously, start bivalirudin 30 minutes later but before PCI.

For patients proceeding to primary PCI who have been treated with ASA and a thienopyridine, recommended supportive anticoagulant regimens include the following:

a. For prior treatment with UFH, additional boluses of UFH should be administered as needed to maintain therapeutic activated clotting time levels, taking into account whether GP IIb/IIIa receptor antagonists have been administered (Class I, LOE: C).b

b. Bivalirudin is useful as a supportive measure for primary PCI with or without prior treatment with UFH (Class I, LOE: B).b

In STEMI patients undergoing PCI who are at high risk of bleeding, bivalirudin anticoagulation is reasonable (Class IIa, LOE: B).b

For prior treatment with fondaparinux, administer additional intravenous treatment with an anticoagulant possessing anti-IIa activity (such as UFH or bivalirudin), taking into account whether GP IIb/IIIa inhibitors have been administered. Note: Because of the risk of catheter thrombosis, fondaparinux should not be used as the sole anticoagulant to support PCI.


PCI PROCEDURES (check if applicable)

Aspiration thrombectomy

Aspiration thrombectomy is reasonable for patients undergoing primary PCI (Class IIa, LOE: B).b

Stent Use (check one if applicable):

DES

BMS

It is reasonable to use a drug-eluting stent (DES) as an alternative to a bare-metal stent (BMS) for primary PCI in STEMI (Class IIa, LOE: B).b

A DES may be considered for clinical and anatomic settings in which the efficacy/safety profile appears favorable (Class IIb, LOE: B).b


ANTICOAGULANT THERAPY (choose one):

Unfractionated Heparin: 60 U/kg IV bolus (maximum 4000 U), followed by IV infusion of 12 U/kg/h (maximum 1000 U/h) initially, adjusted to maintain goal aPTT 1.5 to 2.0 times control (approximately 50 to 70 s); check aPTT in 6 h and adjust heparin as indicated. When using a fibrinolytic, use Unfractionated Heparin Dosing Chart. Note: Regimens other than UFH are recommended if anticoagulant therapy is given for more than 48 hours because of the risk of heparin-induced thrombocytopenia with prolonged UFH treatment.

or

Enoxaparin 30 mg IV, followed by 1 mg/kg SC q12h, first dose 30 minutes after bolus (if age >75 years, give 0.75 mg/kg every 12 hours with no bolus; if CrCl <30 mL/min, give 1 mg/kg every 24 h after bolus). Continue for at least 48 hours, and preferably for the duration of hospitalization, up to 8 days in patients with no contraindications to anticoagulation.

or

Fondaparinux 2.5 mg IV initially, followed by 2.5 mg SC once daily (avoid if CrCl <30 mL/min). Continue for at least 48 hours, and preferably for the duration of hospitalization, up to 8 days in patients with no contraindications to anticoagulation.
