Abstract:

AIM: To explore the relationship between neutrophil/high density lipoprotein ratio (NHR), lymphocyte/high density lipoprotein ratio (LHR), monocyte/high density lipoprotein ratio (MHR) and platelet/high density lipoprotein ratio (PHR) and in-stent restenosis in diabetic patients after percutaneous coronary intervention. METHODS: From November 2021 to November 2024, 110 diabetic patients underwent percutaneous coronary intervention and re-examined coronary angiography were included. They were divided into non-restenosis group (62 cases) and restenosis group (48 cases). The correlation and predictive value of NHR, LHR, MHR and PHR for restenosis were evaluated by univariate/multivariate regression analysis, restricted cubic spline curves, correlation analysis, ROC analysis and decision curve analysis. Nomogram was established. RESULTS: Compared with the non-restenosis group, the levels of low-density lipoprotein cholesterol, lipoprotein (a), NHR, MHR and PHR in the restenosis group increased significantly (P<0.05). Logistic regression analysis showed that NHR, MHR and PHR were independently correlated with the restenosis in diabetic patients after percutaneous coronary intervention, and the levels of NHR, MHR and PHR were positively correlated with the occurrence of restenosis. There was no significant correlation between LHR and restenosis. ROC curve showed that MHR and PHR levels have a good predictive effect on the occurrence of restenosis in diabetic patients after percutaneous coronary intervention. CONCLUSION: NHR, MHR and PHR are significantly correlated with restenosis in diabetic patients after percutaneous coronary intervention, and they are effective indicators for predicting restenosis.
