Variability In Non-HDL-C and Lp(a) Affect The Neutrophil To Lymphocyte Ratio In Patients Undergoing Elective Percutaneous Coronary Intervention

Abstract

Objective: To evaluate the influence of the variability of Lipoprotein a (Lp(a)) and Non-high-density lipoprotein cholesterol (non-HDL-C) on the neutrophil to lymphocyte ratio (NLR) during the follow-up period in patients with coronary heart disease (CHD) after elective coronary intervention.Methods: A total of 3320 consecutive patients with CHD after percutaneous coronary intervention (PCI) in a multi-center from January 2010 to January 2019 were enrolled. The baseline demographic data were Analyzed, and the NLR levels in tertile groups according to the baseline Lp(a) and non-HDL-C levels were compared. Linear regression is used to analyze the association of the variation rate of Lp(a) and non-HDL-C with NLR; and subgroup analysis of the relevant factors were found. All verifications are verified by SD, CV, and VIM triple methods.Results: The NLR is significantly different among tertile Lp(a) variation groups in SD, CV and VIM methods, which is consistent in non-HDL-C variation rate except SD method. Multiple linear regression indicated that Lp(a) variability, age, gender, BMI, hypertension, eGFR were related to NLR, which was verified in age, gender, hypertension and non-diabetic subgroups. Non-HDL-C variability, age, gender, BMI, eGFR, statins, follow-up HDL-C and non-HDL-C were also related to NLR, and established in the above subgroups.Conclusion: The variation rate of Lp(a) and non-HDL-C are independent positive predictors of NLR after elective PCI.
