1 Thrombus Aspiration in ST- Elevation myocardial infarction in Scandinavia ( TASTE trial) Ole Fröbert, MD, PhD - on behalf of the TASTE investigators Departement of Cardiology Örebro University Hospital Sweden Main results at 30 days UCR Uppsala Clinical Research Center

2 Background Intracoronary thrombus aspiration may reduce distal embolization and improve reperfusion No previous randomized trial on thrombus aspiration has been powered for hard endpoints Current ESC recommendation: class IIa with a level of evidence B

3 TAPAS Vlaar, P.J. et al. The Lancet 2008; 371: Fröbert, O. et al. Int J Cardiol. 2010; 145:572-3 TA+PCI (N=3 666) PCI alone (N=16 417) HR (95% CI): 1.21 ( ) / Swedish registry data

4 Methods (1) All 29 Swedish, 1 Icelandic and 1 Danish PCI center Inclusion criteria  STEMI and ability to provide oral consent  <24 h symptoms  correspondence between ECG and angio findings Exclusion criteria  need for emergency CABG  age <18 years  previous randomization in TASTE 1:1 randomization to manual thrombus aspiration and PCI vs. PCI alone

5 Methods (2) Endorsed aspiration catheters  Eliminate (Terumo), Export (Medtronic) and Pronto (Vascular Solutions) Anticoagulation and platelet inhibition according to current guideline recommendations Primary endpoint  time to all-cause death at 30 days Secondary endpoints  time to rehospitalization with reinfarction at 30 days  time to stent thrombosis at 30 days

6 Methods (3) TASTE introduces the Registry-based Randomized Clinical Trial (RRCT) concept Online health quality registries (SCAAR and SWEDEHEART) serve as on-line platforms for:  randomization  case record forms  follow-up

7 All patients with STEMI in Sweden and Iceland undergoing primary or rescue PCI. N= * ) Enrolled in TASTE N=7259 N=3621 assigned to thrombus aspiration N=3399 underwent thrombus aspiration N=222 underwent conventional PCI TASTE trial enrollment flow chart Not enrolled N=4697 N=3623 assigned to conventional PCI N=3535 underwent conventional PCI N=1162 underwent thrombus aspiration N=3445 underwent conventional PCI N=178 underwent thrombus aspiration N=3621 were followed up N=3623 were followed up N=1162 were followed up N=3535 were followed up Enrolled in Denmark N=247 Erroneous enrollments N=15 Randomized in TASTE N=7244 No patients (0) were lost to follow-up of the primary endpoint!

9 Baseline clinical characteristics

10 Baseline procedural characteristics

11 Post randomization characteristics (1) Glycoprotein Iib/IIIa inhibitor

12 Post randomization characteristics (2)

13 All-cause mortality at 30 days HR 0.94 ( ), P=0.63 Per protocol analysis based on actual treatment: HR 0.88 ( ), P=0.38

14 Reinfarction at 30 days HR 0.61 ( ), P=0.09 Per protocol analysis based on actual treatment: HR 0.67 ( ), P=0.19

19 Conclusions This large, prospective, registry-based randomized clinical trial showed:  no reduction of mortality at 30 days  no significant reduction of hospitalization for MI or of stent thrombosis at 30 days  no reduction of other important clinical endpoints during hospitalization Our findings leave little role for manual thrombus aspiration as a routine adjunct to PCI in STEMI
