Influence of stent design on 1-year outcome after coronary stent placement: A randomized comparison of five stent types in 1,147 unselected patients

The objective of this randomized trial was to assess whether differences in stent design are translated in different clinical outcomes in patients und ergoing coronary stent placement. This multicenter randomized trial include d 1,147 patients who were randomly assigned to receive one of five types of stainless steel stents: Inflow, MULTI-LINK, NIR, Palmaz-Schatz, and PURA-A stent. Primary endpoint of the study was event-free survival at 1 year. Ev ent-free survival at 1 year was significantly different between the groups (P = 0.014), ranging from 69.4% to 82.4%. Similarly, freedom from myocardia l infarction was also significantly different (P = 0.022), with values betw een 88.2% and 95.2%. Diameter stenosis at 6 months varied from 38.1% +/- 25 .0% to 45.6% +/- 27.7% (P = 0.046), late lumen loss ranged from 1.01 +/- 0. 70 mm to 1.20 +/- 0.82 mm (P = 0.085), and the incidence of restenosis vari ed between 25.3% and 35.9% (P = 0.145). Thus, stent design has a significan t impact on the long-term results after coronary stent placement. (C) 2000 Wiley-Liss, Inc.
