Impact of strut thickness on late luminal loss after coronary artery stent placement

To determine the influence of coronary artery stent strut thickness on angiographic late luminal loss, 663 patients were included in a single-center observational cohort after receiving an ACS Multilink stent in a native coronary vessel. At 6- to 10-month follow-up, 287 patients treated with a thin-strut stent (50 mum) had significantly less late luminal loss than 376 patients treated with a thick-strut stent (greater than or equal to90 mum) (mean 0.92 +/- 0.59 vs 1.06 +/- 0.71 mm, p = 0.011); on multivariate regression analysis, strut thickness was found to be an independent predictor for late luminal loss.
