ABSTRACT
Objective To evaluate the effect of early intracoronary injection of tirofiban via aspiration catheter on myocardial no-reflow in elderly patients with acute ST-segment elevation myocardial infarction (STEMI).Methods 120 consecutive patients over 65 years old with AMI undergoing primary percutaneous coronary intervention (PCI) were randomized into two groups.In tirofiban group (n=60),thrombus aspiration and intracoronary tirofiban bolus (10 μg/kg prior to the first balloon inflation) via aspiration catheter were performed.In control group (n=60),thrombus aspiration was followed by primary PCI.The incidence of no-reflow and bleeding were assessed in the two groups.Results The moderate to severe bleeding (TIMI bleeding criteria) did not occur in the two groups,there's no significant difference between two groups in the incidence of minor bleeding [26.7%(16 cases) vs.21.7% (13 cases),x2 =0.19,P=0.522].The incidence of myocardial noreflow was significantly lower in tirofiban group than in the control group [10.0% (6/60) vs.25.0% (15/60),x2 =4.68,P=0.031].Conclusions The intracoronary injection of tirofiban via aspiration catheter may significantly reduce the incidence of myocardial no-reflow in patients with STEMI without increasing bleeding complications.
