Brief Summary
The goal of primary PCI is to restore anterograde myocardial flow. Stenting a largely thrombotic lesion may determine distal embolisation of thrombotic material therefore deteriorating myocardial perfusion.

Study Arms (2)
Immediate stenting
ACTIVE COMPARATORPatients being randomized to the immediate stenting arm will be managed according to the guidelines. Irrespective of TIMI flow at presentation, investigators will be requested to thrombus aspirate immediately after successful wiring of the culprit vessel followed by direct stenting. In cases where insertion of thrombus removal catheter and/or direct stenting is not successful, balloon angioplasty will be allowed.
Delayed stenting
EXPERIMENTALPatients being randomized to the delayed/staged stenting arm will be managed with the aim to obtain stable TIMI 3 flow with no considerations given at the percentage of residual stenosis at the culprit lesion. In patients presenting with TIMI 3 flow, investigators will be left free to wire the vessel and proceed to thrombus aspiration to decrease thrombus burden in the culprit lesion or to leave the vessel untreated at the time of index PCI. Patients presenting with suboptimal TIMI flow (i.e. less than 3), investigators are required to wire the vessel and thrombus aspirate. If stable (persisting for at least 5 minutes) TIMI 3 flow is obtained, investigators are requested to stop the procedure. The goal is to achieve s table TIMI 3 flow with no considerations given to the percentage of residual stenosis. Stenting in this arm will be allowed only on a bail-out strategy.
Interventions
Coronary stenting 3 to 7 days after having reopened the vessel in the acute phase
Eligibility Criteria
You may qualify if:
- chest pain for \>30 min with ST-segment elevation of one mm or more in 2 or more contiguous ECG leads or with presumably new left bundle-branch block
- admission either within 12 h of symptom onset or between 12 and 24 h with evidence of continuing ischaemia
You may not qualify if:
- inability to assume an oral P2Y12 receptor blocker on a consecutive daily basis for a minimum of 6 months, or to heparin or aspirin
- uncontrolled hypertension (systolic or diastolic arterial pressure \>180 mmHg or 120, respectively, despite medical therapy)
- limited life expectancy, e.g. neoplasms, others
- inability to obtain informed consent
- pregnancy
- patients were not enrolled if they were clinically unstable, presented with severe arrhythmia, or had known contraindications to CMR (claustrophobia, pacemakers, or implantable defibrillator devices)
