  2. 3T/2R Troponin I or T >3x ULN at 48 hours: 20% for tirofiban vs. 35% for placebo (p = 0.009) MACE at 30 days: 21% vs. 37% (0.006), respectively TIMI major bleeding at 30 days: 0 vs. 0 Trial design:Patients undergoing PCI were screened for poor response to aspirin and/or clopidogrel. Poor responders were then randomized to tirofiban (n = 132) or placebo (n = 131). Follow-up was 30 days. Results (p = 0.009) (p = 0.006) 37 35 % 20 21 Conclusions • Tirofiban is beneficial at reducing MI within 48 hours after PCI among poor responders to aspirin and/or clopidogrel • Tirofiban also reduced MACE at 30 days • There were no major bleeds in either group Troponin I or T >3x ULN at 48 hours MACE at 30 days Tirofiban Placebo Presented by Dr. Marco Valgimigli at ESC 2008

  3. APPRAISE-1 ISTH major or CRNM bleeding: 7.9% for 10 mg apixaban, 5.7% for 5 mg apixaban, 3% for placebo (p = 0.005 for high-dose vs. placebo and p = 0.09 for low-dose vs. placebo) Death, MI, recurrent ischemia, or stroke: 6.0%, 7.6%, 8.7% (p = 0.07 for high-dose vs. placebo and p = 0.21 for low-dose vs. placebo), respectively Trial design:Patients recovering from an ACS were randomized to apixaban 10 mg daily (n = 318), apixaban 2.5 mg twice daily (n = 317), or placebo (n = 611).
