Comparison of general data and comparison of the incidence of plaques in bifurcation zone of the LCA among the RI distribution groups
DIABETES MELLITUS, PLAQUE, HYPERTENSION, HYPERLIPIDEMIA
The differences in general information (age, sex, history of hypertension, history of diabetes mellitus, history of hyperlipidemia, history of smoking, and ∠LAD-LCX angle) were not statistically significant when comparing the three groups (P > 0.05, see Table
