Abstract:
Objective To investigate the effects of Tirofiban combined with thrombus aspiration on myocardial reperfusion and no-reflow after percutaneous coronary intervention (PCI)in elderly patients with ST-segment elevation myocardial infarction (STEMI).Methods A total of 185 patients with STEMI were randomly divided into a control group(n=93)and a study group(n=92).The control group received direct stenting or percutaneous coronary angioplasty before stent placement.The study group received an intracoronary injection of Tirofiban 10 μg/kg,thrombus aspiration,and then balloon dilatation or direct coronary stenting.Postoperative recovery was compared between the groups,and major adverse cardiovascular events(MACE) were recorded.Results The incidence of no-reflow,the thrombolysis in myocardial infarction,the corrected (TIMI)frame count (CTFC)and the peak of plasma creatine kinase MB isoenzyme(CK MB)were lower in the study group than in the control group[(no reflow,8 cases or 8.7 % vs.21cases or 22.6 %,x2 =6.752,P <0.05;CTFC,(26.4±8.7)frame vs.(34.5± 8.2)frame,t =6.517,P<0.05;CK-MB peak,(114.5±25.7)U/L vs.(226.3 ± 27.6) U/L,t =28.506,P < 0.05].The proportion of patients with descent of ST segment elevation of more than 50% and the left ventricular ejection fraction(LVEF)were higher in the study group than in the control group[83 cases or 90.2% vs.72 cases or 77.4%,x2=5.581,P<0.05;(56.2±8.6) % vs.(48.8±10.5)%,t =5.241,P<0.05].The TIMI grading was better in the study group than in the control group (Z =1.984,P < 0.05).The incidence of mild bleeding during treatment had no significant difference between the study group and the control group(20.7% or 19 cases vs.15.1% or 14 cases,x2 =0.99,P =0.32).There was no significant difference in the incidence of MACE events during hospitalization or one-year follow-up between the two groups(x2=2.394,0.452,P > 0.05).Conclusions Tirofiban combined with thrombus aspiration can improve myocardial reperfusion in elderly patients with STEMI after PCI,and has excellent clinical value.
