Brief summary
Primary percutaneous coronary intervention represents the gold standard for the treatment of ST-segment-elevation acute myocardial infarction. However, periprocedural bleedings are associated with an increased risk of mortality, re-infarction, and stroke. Although the prognostic value of access site related bleeding complications is still debated, transradial approach is associated with better short-term outcomes and reduced hospital stay as compared to transfemoral approach. The investigators aimed to compare transradial approach with transfemoral approach with systematic achievement of hemostasis by the implantation of a vascular closure device in a national multicentre randomized clinical trial.
Interventions
PROCEDURETransradial primary percutaneous coronary intervention
Transradial coronary angiography will be performed by the Judkins technique using 6 French diameter sheaths and pre-molded catheters for selective catheterization of left and right coronary arteries. Primary percutaneous coronary intervention with stent deployment will be indicated when a culprit lesion is identified, with high probability of angiographic success, being ideally performed immediately after coronary angiography Procedures will be performed according to recommendations of current guidelines. To achieve hemostasis in the transradial approach, a radial compression device will be applied, to maintain patent antegrade flow.
PROCEDURETransfemoral primary percutaneous coronary intervention
Transfemoral coronary angiography will be performed by the Judkins technique using 6 French diameter sheaths and pre-molded catheters for selective catheterization of left and right coronary arteries. Primary percutaneous coronary intervention with stent deployment will be indicated when a culprit lesion is identified, with high probability of angiographic success, being ideally performed immediately after coronary angiography Procedures will be performed according to recommendations of current guidelines. A vascular closure device will be used to achieve hemostasis in the transfemoral approach, preceded by systematic performance of femoral angiography and maintaining absolute bed rest for 60 minutes.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Major vascular access site complications | 48 hours post-procedure | Major vascular complications related to arterial access site will be evaluated during hospitalization by physical examination and duplex ultrassonography and include major bleeding, retroperitoneal hemorrhage, compartment syndrome, pseudoaneurysm, arteriovenous fistula, limb ischemia or need for vascular surgery repair. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Device success | 48 hours post-procedure | The success of the device is defined as the attainment of adequate hemostasis at the end of the procedure, without the need to apply other compression methods. |
