Inclusion criteria

Inclusion criteria: Inclusion criteria: the duration of symptoms more than six hours, anomalies of involved coronary artery including blocked artery in primary angiography primary perfusion (TIMI0.1) , high volume of thrombosis, high length of lesion (more than 24 mm , small diameter of vessels (less than 5.2 mm ) , clinical signs of acute injury of micro-vascular after primary perfusion (with increasing ST more than 50%) Exclusion criteria include the lack of normal coronary flow (TIMI3) after primary perfusion treatment with thrombus aspiration with or without balloon angioplasty, cardiogenic shock and inability to obtain informed consent.

Design outcomes

Primary

Measure	Time frame
No/slow reflow. Timepoint: In the first group (immediate) measured immediately after angiography. Method of measurement: By Echocardiography.This outcome has three degrees : lack of blood flow (TIMI0), incomplete filling (TIMI1), establish low blood flow but with complete filling (TIMI2) in involved coronary artery during or at the end of PCI.	—

Secondary

Measure	Time frame
The consequences of electrocardiographic. Timepoint: One hour after treatment compared _ basic ECG, before reperfusion. Method of measurement: By electrocardiogram Complete resolution of ST elevation 70% 30 %.;The consequences of Angiographic. Timepoint: At the end of the first procedure as prospective. Method of measurement: By Angiography, stent dimensions are compared with real stent at the second procedure by the same operator.;The consequences of Echocardiography. Timepoint: Before the first procedure and discharge. Method of measurement: Based on wall motion score index.	—
