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 μm) had significantly less late luminal loss than 376 patients treated with a thick-strut stent (≥90 μm) (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.
