Abstract:
Objective To compare the efficacy of thrombus aspiration catheter combined with intracoronary tirofiban and nitroglycerol injection through the aspiration catheter versus the guiding catheter during primary percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI).Methods Thirty-four patients with STEMI undergoing primary PCI and receiving thrombus aspiration catheter combined with intracoronary tirofiban and nitroglyeerol injection through the aspiration catheter were enrolled as the aspiration group (n =34),and those who had similar coronary angiography results and basic characteristics but receiving thrombus aspiration catheter combined with intracoronary tirofiban and nitroglycerol injection through the guiding catheter were served as the guiding group ( n =33 ).The outcomes of the two groups were observed and compared.Results There was no significant change of blood pressure between before and after injection in the aspiration group ( P ＞ 0.05 ),but the change of blood pressure was significant after injection compared with before injection in the guiding group ( P ＜ 0.01 ).The cTn-I,BNP,peak-value of CK-MB,peak-time of CK-MB,TIMI grade 3 flow,slow-reflow in IRA after PCI in the aspiration group were superior to those in the guiding group ( t =3.92,P ＜ 0.01 ;t =4.70,P ＜ 0.01 ; t =3.39,P ＜ 0.01 ; t =7.17,P ＜0.01 ; x2 =3.877,P ＜ 0.05 ; x2 =3.876,P ＜ 0.05 ).LVEF,LVEDd and LVESd after 1 month in the aspiration group were superior to those in the guiding group (t =5.99,P ＜ 0.01 ;t =4.53,P ＜ 0.01 ;t =8.12,P ＜ 0.01 ),but no significant differences of LVEF,LVEDd,LVESd were found after 1 week resolution of sum of ST-segment elevation and the MACE rates after PCI were found between the two group ( P ＞ 0.05 ).Conclusion Application of thrombus aspiration catheter combined with intracoronary tirofiban injection through the aspiration catheter is more effective than through the guiding catheter in patients with Acute ST-segment elevation myocardial infarction,which could decrease slow-reflow phenomenon and improve re-perfusion and left ventricular function with better clinical outcomes.
