Background: Adequate endothelization after drug-eluting stent (DES) implantation is essential to reduce thrombotic risk. Adequate strut coverage (ASC) is defined as ≥40 μm on optical coherence tomography, but its functional significance remains uncertain. Coronary angioscopy can assess neointimal function by detecting thrombus and plaque color. This study evaluated functionally adequate endothelization and contributing factors after DES implantation.
Nishino et al. (Mon,) studied this question.
