Values are presented as mean ± SD or n (percentage). Small vessel is defined as the diameter of the vessel ≤ 2.5 mm. Long lesion is defined as the total length of the lesion ≥ 30 mm. CTO: chronic total occlusion; LAD: left anterior descending artery; LCX: left circumflex artery; LM: left main artery; MCAD: mature coronary artery disease; PCAD: premature coronary artery disease; and RCA: right coronary artery. p≤0.001, p≤0.01, and p≤0.05.
