Abstract Objective To investigate the changes of SYNTAX and SYNTAX Ⅱ scores in patients with coronary artery heart disease (CHD) after percutaneous coronary intervention (PCI) with different low-density lipoprotein cholesterol (LDL-C) level. Methods A total of 150 patients who underwent PCI for CHD in Wujin Hospital Affiliated to Jiangsu University from October 2017 to December 2019 were selected as the research objects. LDL-C level was detected after PCI, and SYNTAX and SYNTAX Ⅱ scores were calculated, and clinical data of patients were collected. According to their LDL-C levels, all research objects were divided into low LDL-C level group (LDL-C<1.4 mmol/L, 23 cases), non-low LDL-C level group (1.4≤LDL-C <1.8 mmol/L, 54 cases) and substandard LDL-C group (LDL-C≥1.8 mmol/L, 73 cases). The changes of SYNTAX and SYNTAX Ⅱ scores in the three groups after PCI were compared. Results There was no significant difference in clinical data among the three groups (all P > 0.05). There were statistically significant differences in SYNTAX and SYNTAX Ⅱ scores among the three groups after PCI (P < 0.05). Further pair comparison showed that SYNTAX and SYNTAX Ⅱ scores of the non-low LDL-C level group and the substandard LDL-C group were higher than those of the low LDL-C level group. The scores of SYNTAX and SYNTAX Ⅱ in the substandard LDL-C group were higher than those in the non-low LDL-C level group, and the differences were statistically significant (all P < 0.05). Conclusion Low LDL-C level can further delay the progression of coronary artery in patients with CHD after PCI.
