Abstract
There are little direct comparative evidences of strategies between ≥50% and the absolute target goal of low-density lipoprotein cholesterol (LDL-C) level <55 mg/100 ml for the patients who underwent percutaneous coronary intervention (PCI). This study aimed to investigate the clinical impact of different strategies between 2 groups of patients who underwent PCI. A total of 3,104 patients with previous PCI were retrospectively enrolled from 2014 to 2020 at Yeungnam University Medical Center. The study population was stratified into 2 groups based on whether the LDL-C level was <55 mg/100 ml at the 1-year mark or not. Furthermore, the 50% reduction rate of LDL-C was also categorized based on whether it had decreased by ≥50% from the initial LDL-C level at the 1-year mark. The primary end point was 3-year major adverse cardiovascular events (MACEs) which were defined as a composite of cardiovascular death, nonfatal myocardial infarction, target lesion revascularization, hospitalization for heart failure, or nonfatal stroke. There was no significant difference between the LDL <55 mg/100 ml group and the LDL ≥55 mg/100 ml group in the risk of MACEs (hazard ratio 1.06, 95% confidence interval 0.81 to 1.38, p = 0.690) after propensity score matching. However, the group that achieved ≥50% reduction of LDL-C from baseline LDL-C level showed a significant reduction in the occurrence of MACEs in the subgroup of LDL-C level ≥55 mg/100 ml (hazard ratio 0.41, 95% confidence interval 0.19 to 0.89, p = 0.025) compared with the group with <50% reduction of LDL-C. In all patients, the achievement rate of target LDL-C <55 mg/100 ml and more than 50% reduction from baseline was 17.2%. In conclusion, guideline-directed management strategy of ≥50% reduction of LDL-C from the baseline will be needed to reduce the incidence of MACEs in patients with LDL-C ≥55 mg/100 ml who underwent PCI. Additional efforts to increase the target goal achievement rate of LDL-C are warranted.
