Fig. 2: Canadian Cardiovascular Society Working Group algorithm for the selection of patients for reperfusion after ST-segment myocardial infarction (STEMI). The algorithm applies to patients presenting within 12 hours after symptom onset; it assumes that the diagnosis of STEMI is not in doubt and indicates that, for the current majority of hospitals caring for non-high-risk STEMI patients, fibrinolysis is the preferred option. ECG = electrocardiogram, PCI = percutaneous coronary intervention. Reproduced with permission from reference 4.
