following: signs of HF, evidence of a low output state,
increased risk for cardiogenic shock,* or other
contraindications to use of oral beta blockers (PR interval
>0.24 seconds, second- or third-degree heart block, active
asthma, or reactive airways disease).
Beta blockers should be continued during and after
hospitalization for all patients with STEMI and with no
contraindications to their use.

*Risk factors for cardiogenic shock (the greater the number of risk factors present, the higher the
risk of developing cardiogenic shock) are age >70 years, systolic BP <120 mm Hg, sinus
tachycardia >110 bpm or heart rate <60 bpm, and increased time since onset of symptoms of
STEMI.
39. Beta Blockers
Patients with initial contraindications to the use of beta
blockers in the first 24 hours after STEMI should be
reevaluated to determine their subsequent eligibility.
It is reasonable to administer intravenous beta blockers at
the time of presentation to patients with STEMI and no
contraindications to their use who are hypertensive or
have ongoing ischemia.

• Ticagrelor 90 mg twice a day*
*The recommended maintenance dose of aspirin to be used with ticagrelor is 81 mg

It is reasonable to use 81 mg of aspirin per day in preference to
higher maintenance doses after primary PCI.
I IIa IIb III
72. Antiplatelet Therapy to Support
Primary PCI for STEMI
It is reasonable to start treatment with an intravenous GP IIb/IIIa
receptor antagonist at the time of primary PCI (with or without
stenting or clopidogrel pretreatment) in selected patients with
STEMI who are receiving UFH.
• Double-bolus eptifibatide: 180 mcg/kg IV bolus, then 2

77. Anticoagulant Therapy to Support
Primary PCI
For patients with STEMI undergoing primary PCI, the following
supportive anticoagulant regimens are recommended:
• UFH, with additional boluses administered as needed to
maintain therapeutic activated clotting time levels, taking into
account whether a GP IIb/IIIa receptor antagonist has been
administered; or
• Bivalirudin with or without prior treatment with UFH.
I IIa IIb III
I IIa IIb III
78. Anticoagulant Therapy to Support
Primary PCI
In patients with STEMI undergoing PCI who are at high risk of
bleeding, it is reasonable to use bivalirudin monotherapy in
preference to the combination of UFH and a GP IIb/IIIa receptor
antagonist.
Fondaparinux should not be used as the sole anticoagulant to
support primary PCI because of the risk of catheter thrombosis.

86. Fibrinolytic Therapy When There Is an

Within 120 Minutes of FMC
In the absence of contraindications, fibrinolytic therapy should be
given to patients with STEMI and onset of ischemic symptoms
within the previous 12 hours when it is anticipated that primary
PCI cannot be performed within 120 minutes of FMC.
In the absence of contraindications and when PCI is not
available, fibrinolytic therapy is reasonable for patients with
STEMI if there is clinical and/or ECG evidence of ongoing
ischemia within 12 to 24 hours of symptom onset and a large
area of myocardium at risk or hemodynamic instability.
Fibrinolytic therapy should not be administered to patients with
ST depression except when a true posterior (inferobasal) MI is
suspected or when associated with ST elevation in lead aVR.

Patients with STEMI undergoing reperfusion with fibrinolytic therapy
should receive anticoagulant therapy for a minimum of 48 hours, and
preferably for the duration of the index hospitalization, up to 8 days or
until revascularization if performed. Recommended regimens include:
a. UFH administered as a weight-adjusted intravenous bolus and
infusion to obtain an activated partial thromboplastin time of 1.5 to
2.0 times control, for 48 hours or until revascularization;
b. Enoxaparin administered according to age, weight, and creatinine
clearance, given as an intravenous bolus, followed in 15 minutes by
subcutaneous injection for the duration of the index hospitalization,
up to 8 days or until revascularization; or
c. Fondaparinux administered with initial intravenous dose, followed in
24 hours by daily subcutaneous injections if the estimated creatinine
clearance is greater than 30 mL/min, for the duration of the index

99. CABG in Patients With STEMI
Urgent CABG is indicated in patients with STEMI and coronary
anatomy not amenable to PCI who have ongoing or recurrent ischemia,
cardiogenic shock, severe HF, or other high-risk features.
CABG is recommended in patients with STEMI at time of operative
repair of mechanical defects.

100. CABG in Patients With STEMI
The use of mechanical circulatory support is reasonable in patients with
STEMI who are hemodynamically unstable and require urgent CABG.
Emergency CABG within 6 hours of symptom onset may be considered
in patients with STEMI who do not have cardiogenic shock and are not
candidates for PCI or fibrinolytic therapy.

Emergency revascularization with either PCI or
CABG is recommended in suitable patients with
cardiogenic shock due to pump failure after STEMI
irrespective of the time delay from MI onset.
In the absence of contraindications, fibrinolytic
therapy should be administered to patients with
STEMI and cardiogenic shock who are unsuitable
candidates for either PCI or CABG.

105. Treatment of Cardiogenic Shock
The use of intra-aortic balloon pump counterpulsation
can be useful for patients with cardiogenic shock after

cardiogenic shock.

Recommendations Class/Level
ASA is recommended for all patients without contraindications at an initial oral
loading dose of 150–300 mg (or 80–150 mg i.v.), and at a maintenance dose of
75–100 mg daily long-term regardless of treatment strategy.
I A
A P2Y12 inhibitor is recommended in addition to ASA, and maintained over 12
months unless there are contraindications such as excessive risk of bleeding.
Options are:
I A
• Prasugrel (60 mg loading dose, 10 mg daily dose) in patients in whom
coronary anatomy is known and who are proceeding to PCI if no
contraindication.
I B
• Ticagrelor (180 mg loading dose, 90 mg twice daily) for patients at
moderate-to-high risk of ischaemic events, regardless of initial treatment
strategy including those pre-treated with clopidogrel if no contraindication.
I B
• Clopidogrel (600 mg loading dose, 75 mg daily dose), only when
prasugrel or ticagrelor are not available or are contraindicated.
