Values are mean (SD) when appropriate. DM, type 2 diabetes mellitus; LAD, left anterior descending artery; LCX, left circumflex artery; RCA, right coronary artery. Fisher’s exact test was used for categorical data; unpaired Student t test was used for continuous data between DM and non-DM groups. Values of p<0.05 were considered statistically significant.
