Probability values refer to the univariate analysis and are corrected for the clustering of stents within patients. ACS indicates acute coronary syndrome; BL, baseline; ESS, endothelia shear stress; FU, follow‐up; ISH, in‐stent hyperplasia; LA, lumen area; PA, plaque area; PB, plaque burden; SA, stent area; VA, vessel area.
