|Immediate transfer for cardiogenic shock or severe acute HF irrespective of time delay from MI onset||I||B||(128)|
|Urgent transfer for failed reperfusion or reocclusion||IIa||B||(129–132)|
|As part of an invasive strategy in stable⁎ patients with PCI between 3 and 24 h after successful fibrinolysis||IIa||B||(133–138)|
COR indicates Class of Recommendation; HF, heart failure; LOE, Level of Evidence; MI, myocardial infarction; N/A, not available; and PCI, percutaneous coronary intervention.
↵⁎ Although individual circumstances will vary, clinical stability is defined by the absence of low output, hypotension, persistent tachycardia, apparent shock, high-grade ventricular or symptomatic supraventricular tachyarrhythmias, and spontaneous recurrent ischemia.
