Data are mean±SD for continuous variables with or % (n) for categorical variables. The number of patients with available data is indicated in brackets. The p value for the comparison over all 4 regions was <0.0001 for all variables, except for left main (overall p=0.017) and RCA (overall p=0.21). A * indicates a p value <0.05 for the difference in characteristics between the region as compared with Europe.
Lesion characteristics at index procedure are reported. Small vessels are defined as at least 1 stent with diameter ≤2.75 mm. Long lesions are defined as at least 1 stent with length ≥25 mm.
ACC/AHA, American College of Cardiology/American Heart Association; CFX, circumflex; CTO, chronic total occlusion; LAD, left anterior descending artery; RCA, right coronary artery.
