Angiographic success was 96% in both groups; an average of 1.3 stents were used in both arms. 619 patientswith ST-elevation myocardial infarction with chest pain for > 20 minutes and ST-elevation in ≥2 contiguous leads; infarct related artery with a de novo lesion 619 patients with ST-elevation myocardial infarction with chest pain for > 20 minutes and ST-elevation in ≥2 contiguous leads; infarct related artery with a de novo lesion Randomized. 24% female, mean age 61 years, mean follow-up 1 year Use of GP IIb/IIIa inhibitors abciximab or tirofiban at discretion of physician Time to balloon was 3.1 hours; LAD artery was the culprit in 50% of patients, 45% had multi-vessel disease.

Clinical trial results.org PASSION Trial: Components of Primary Endpoint Occurrences of Death or MI were not significantly different between the paclitaxel-eluting stent group and the bare metal stent group (4.8% vs. 6.5%, p=0.39)Occurrences of Death or MI were not significantly different between the paclitaxel-eluting stent group and the bare metal stent group (4.8% vs. 6.5%, p=0.39) There was also no difference in TLR (6.2% vs. 7.4%, p=0.23)There was also no difference in TLR (6.2% vs. 7.4%, p=0.23) There were 3 cases of stent thrombosis in each groupThere were 3 cases of stent thrombosis in each group % Death/MI and TLR Presented at ACC 2006 Components of Primary endpoint (%) p=0.39 p=0.23 4.8% 6.5% 6.2% 7.4%

6. www. Clinical trial results.org PASSION Trial: Limitations The TLR rate was very low in both arms which may be due to the fact that not all patients were brought back for angiographic follow-up. The “oculostenotic reflex” is thought to lead to higher TLR rates.The TLR rate was very low in both arms which may be due to the fact that not all patients were brought back for angiographic follow-up.

Clinical trial results.org PASSION Trial: Summary Among patients undergoing primary PCI for ST-elevation MI, use of paclitaxel- eluting stents was not associated with a difference in the primary composite endpoint of death, MI or target lesion revascularization when compared to bare metal stents at one year.Among patients undergoing primary PCI for ST-elevation MI, use of paclitaxel- eluting stents was not associated with a difference in the primary composite endpoint of death, MI or target lesion revascularization when compared to bare metal stents at one year. Occurrences of death or MI were not significantly different between the two groups (4.8% vs. 6.5%, p=0.39) nor was there a difference in TLR (6.2% vs. 7.4%, p=0.23).Occurrences of death or MI were not significantly different between the two groups (4.8% vs. 6.5%, p=0.39) nor was there a difference in TLR (6.2% vs. 7.4%, p=0.23). Although the TYPHOON trial showed that sirolimus-eluting stents significantly reduced target vessel failure compared with bare metal stents, it is difficult to compare these results since PASSION enrolled patients with left main disease, bifurcation lesions, and large thrombus while TYPHOON excluded these patients.Although the TYPHOON trial showed that sirolimus-eluting stents significantly reduced target vessel failure compared with bare metal stents, it is difficult to compare these results since PASSION enrolled patients with left main disease, bifurcation lesions, and large thrombus while TYPHOON excluded these patients.
