A retrospective study on the correlation between serum MHR, NLR and recurrence of coronary events after coronary stent implantation in elderly patients

This study analyzes the recurrence of coronary events and their relationship with the monocyte to high-density lipoprotein cholesterol ratio (MHR) and neutrophil to lymphocyte ratio (NLR) in elderly patients with coronary stent implantation. A retrospective analysis was performed on 136 cases elderly patients who received coronary stent implantation in ShengLi Oil Field Central Hospital from December 2019 to June 2023. According to the recurrence of coronary events within 1 year after surgery, patients were divided into recurrence group and non-recurrence group. The MHR and NLR values of the 2 groups were compared. Spearman correlation was used to analyze the correlation between MHR and NLR and postoperative coronary event recurrence in elderly patients with coronary stent implantation, and the predictive value of MHR and NLR values on postoperative coronary event recurrence was analyzed using receiver operating characteristic. The levels of MHR and NLR in recurrent group were higher than those in non-recurrent group (P < .05). Spearman correlation analysis showed that the levels of MHR and NLR were positively correlated with the recurrence of coronary events in elderly patients after coronary stent implantation (r = 0.342, 0.412, P < .05). Receiver operating characteristic curve showed that the area under curve of MHR and NLR combined prediction of postoperative coronary event recurrence was 0.972, the sensitivity was 97.14%, the specificity was 90.10%, and the combined prediction efficiency was better than that of each indicator alone (P < .05). The levels of MHR and NLR are closely related to the recurrence of postoperative coronary events in elderly patients with coronary stent implantation. Early determination of MHR and NLR levels can predict the recurrence of postoperative coronary events in elderly patients with coronary stent implantation.
