Abstract:
Objective:To explore influence of preoperative tirofiban usage and using time on blood flow of infarct re-lated artery (IRA) in patients with acute ST elevation myocardial infarction (ASTEMI ) undergoing emergency di-rect percutaneous coronary intervention (PCI ) .Methods:A total of 266 ASTEMI patients undergoing direct PCI from Jan 2009 to Oct 2012 ,were randomly divided into tirofiban group (n=134 ,received preoperative tirofiban us-age for PCI) and routine treatment group (n=132 ,didn't receive tirofiban during PCI) .According to percutaneous using time of tirofiban tirofiban group was divided into <3h group (n= 63) and ≥3h group (n= 71) ;TIMI blood flow of IRA ,before and after PCI were compared among different groups .Results:Compared with routine treat-ment group before PCI ,there were significant rise in percentages of TIMI grade 3 (10.6% vs .20.9% ) in tirofiban group ,P=0.028 ;after PCI ,percentage of TIMI grade 3 in tirofiban group was more significantly rose than that of routine treatment group (78.8% vs .92.5% ,P=0.001);in tirofiban group ,blood flow of IRA before PCI in <3h group was significantly improved compared with ≥3h group (TIMI grade 2 + 3 ,63.5% vs .29.6% , P<0.01) . Conclusion:Early tirofiban usage can improve TIMI blood flow of IRA before and after PCI in ASTEMI patients , the earlier it′s used ,the more significant effect it has .
