Table 2. Pre-stenting Optical Coherence Tomography Characteristics.
Continuous not-normally-distributed variables are presented as median (interquartile range). Frequencies are expressed as number (percentage).
(ATV: athero-thrombus volume; IMR: index of microcirculatory resistance; LA: Lumen Area; LD: lumen diameter; ROI: region of interest; TV: thrombus volume)
