High-density lipoprotein-related inflammatory indices predict repeat revascularization in coronary drug-eluting stenting

Abstract

Background: HDL-C-related inflammatory indices are potential predictors of repeat revascularization (RR) after coronary drug-eluting stenting. Methods: Multivariable Cox regression with restricted cubic splines and receiver operating curve was used. Results: The median follow-up was 50 months. A total of 521 (35.42%) patients experienced RR. The incidence of RR was positively associated with the monocyte-to-HDL-C ratio, neutrophil-to-HDL-C ratio and lymphocyte-to-HDL-C ratio (log-rank p < 0.05). After being fully adjusted, the largest tertile of monocyte-to-HDL-C ratio, neutrophil-to-HDL-C ratio, white blood cell-to-HDL-C ratio and lymphocyte-to-HDL-C ratio increased the risk by 38, 30, 28 and 37%, respectively. Monocyte-to-HDL-C ratio was dose-responsive and linearly correlated with RR. HDL-C-related inflammatory indices had over 60% predictive ability. Conclusion: HDL-C-related inflammatory indices independently predicted RR after coronary drug-eluting stenting.
