Randomization is performed before coronary angiography. All patients are treated medically according to current international guidelines. Patients are assigned to treatment with MGS or MT pretreatment followed by BMS implantation in the infarct‐related artery.

Study design: The MGUard versus bAre‐metal stents plus manual thRombectomy in ST‐elevation myocarDial Infarction pAtieNts (GUARDIAN) is a multicentre, prospective, randomized, noninferiority, open‐label trial with a planned inclusion of 556 STEMI patients. Purpose: We intend to determine whether MGS implantation is comparable with a strategy of MT pretreatment followed by BMS deployment. MGuard net protective stent (MGS, Inspire‐MD, Tel‐Aviv, Israel) is a new bare‐metal stent (BMS) with a polyethylene theraphthalate mesh coverage anchored to the external surface of the struts aiming to minimize distal embolization during PCI.


In this setting, manual thrombectomy (MT) resulted in better perfusion and clinical outcomes when compared with “conventional” PCI (direct stenting or stenting after predilation).
