Short‐ and mid‐term influence of drug‐coated stent implantation on structural and functional vascular healing response: An optical coherence tomography and acetylcholine testing study
Objective This study investigated the effect of a drug‐coated stent (DCS) that has a novel microporous abluminal surface without a polymer on 1‐month and 1‐year functional and morphological healing response as assessed using acetylcholine (Ach) testing and optical coherence tomography (OCT). Background DCS is expected to induce favorable morphological and physiological arterial healing after its implantation. Methods A total of 11 patients who underwent vascular response examinations 1‐month and 1‐year after the index PCI with DCS implantation were enrolled. The vascular response was evaluated by the functional response test by acetylcholine infusion, the morphological response ...
