    BackgroundAlthough dyslipidemia increases the risk of coronary heart disease (CHD) and its adverse prognosis, the association between the ratio of low-density lipoprotein cholesterol (LDL-C) to high-density lipoprotein cholesterol (HDL-C) and major adverse cardiovascular and cerebrovascular events (MACCE) after percutaneous coronary intervention (PCI) in patients with CHD has not been adequately demonstrated. Therefore, the aim of this study was to assess the role of LDL-C/HDL-C in the risk of MACCE after PCI in patients with CHD.MethodsIn this large cohort observational study, we enrolled 2226 patients with CHD treated with PCI. LDL-C/HDL-C was considered as an exposure variable and MACCE was considered as an outcome variable. Univariate and multivariate Logistic regression models and subgroup analyses were used to assess the relationship between LDL-C/HDL-C and the risk of MACCE.ResultsA total of 2226 patients (mean age: 60.02 years; 68.00% male) were included in the analysis, and 373 patients suffered MACC. Patients who developed MACCE had higher levels of LDL-C/HDL-C compared to patients who did not develop MACCE [(2.79 ± 1.15) vs (2.64 ± 1.09), p = 0.023]. Univariate Logistic regression analysis showed a correlation between LDL-C/HDL-C and the risk of MACCE (OR: 1.121, 95% CI: 1.019-1.233, p = 0.019). Multivariate Logistic regression analysis showed that higher levels of LDL-C/HDL-C remained strongly associated with a higher risk of MACCE after stepwise adjustment for confounding variables [Model 4: T3 vs T1, OR: 1.455, 95% CI: 1.095-1.933, p = 0.010; per unit increase, OR: 1.158, 95% CI: 1.047-1.281, p = 0.004]. Further subgroup analysis showed that the association between LDL-C/HDL-C and MACCE risk remained in the subgroup ≤60 years, male, without diabetes, and with hypertension (p < 0.05).ConclusionHigher LDL-C/HDL-C was closely associated with a higher risk of MACCE after PCI in patients with CHD.
