ABSTRACT
Objective To study the effect of reducing no-reflow after PCI treatment by early using Tirofiban and suction catheter in AMI patients .Methods 76 cases of patients were divided into group A (38 cases) and group B(38 cases) .The group A began to use Tirofiban with suction catheter to aspiration after coronary guidewire entering ,the suction were used in group B when the thrombus burden became exacerbation after balloon dilation .In addition ,chosen 38 cases of AMI patients treated with Tirofiban af-ter balloon dilation as group C .The influence of different treatment options to no-reflow and slow blood flow ,cardiovascular adverse events and the incidence of bleeding were observed .Results Group A compared with other two groups ,the no-reflow and slow flow rate had statistically significant differences (P0 .05) .After three different surgical treatments ,the incidence of bleeding complications had no significant difference (P>0 .05 .The occurrence of adverse cardiovascular events had statistically significant between A group and C (P<0 .05) ,but there was no statistically significant difference between group B and group C (P<0 .05) .Conclusion Three kinds of treatment all have certain effect to reduce no-reflow in emergency PCI of AMI ,but early use of tirofiban with suction catheter in treatment of emergen-cy treatment has great clinical significance to reduce no-reflow .This study provides an effective treatment plan to reduce no-reflow in PCI for AMI .
