The general data of the two groups and the comparison of the incidence of plaques in the bifurcation zone of the LCA

HYPERLIPIDEMIA, PLAQUE, PLAQUE, REGRESSION, HYPERTENSION, DIABETES
There was no statistically significant difference between the pre-PSM RI group and the no-RI group in terms of gender, history of hypertension, history of hyperlipidemia, and history of smoking (P > 0.05, see Table
