Correlates of Delayed Initial Contact to Emergency Services among Patients with Suspected ST-Elevation Myocardial Infarction

Table 1

Summary of time targets following acute MI from the European Society of Cardiology.

Intervals	Time targets
Maximum time from FMC to ECG and diagnosis	≤10 minutes
Maximum expected delay from STEMI diagnosis to primary PCI to choose PCI versus fibrinolysis (if this target time cannot be met, consider fibrinolysis)	≤120 minutes
Maximum time from STEMI diagnosis to wire crossing in patients presenting at primary PCI hospitals	≤60 minutes
Maximum time from STEMI diagnosis to wire crossing in transferred patients	≤90 minutes
Maximum time from STEMI diagnosis to bolus or infusion start of fibrinolysis in patients unable to meet primary PCI target times	≤10 minutes
Time delay from the start of fibrinolysis to evaluation of its efficacy (success or failure)	60–90 minutes
Time delay from the start of fibrinolysis to angiography (if fibrinolysis is successful)	2–24 hours

ECG = electrocardiogram; FMC = first medical contact; PCI = percutaneous coronary intervention; STEMI = ST-elevation myocardial infarction [8].
