Abstract:

Objective To investigate the role of monocyte-to-high-density lipoprotein cholesterol ratio(MHR)in the prognosis assessment of patients with myocardial infarction with non-obstructive coronary artery(MINOCA). Methods A total of 158 MINOCA patients from the People's Hospital of Bozhou from June 1,2018 to December 31,2021 were enrolled. The clinical data and laboratory determination results were collected,and the MHR was calculated. All the patients were followed up for at least 18 months,with the longest follow-up period being 60 months. The occurrence of major adverse cardiovascular events(MACE)within 18 months after coronary arteriography was recorded. Multivariate Logistic regression analysis was used to evaluate the influencing factors of MACE occurrence in MINOCA patients for 18 months after surgery. Receiver operating characteristic(ROC)curve was used to evaluate the efficacy of MHR in predicting MACE occurrence in MINOCA patients for 18 months after surgery. The survival status of MINOCA patients was analyzed by Kaplan-Meier survival curve. Results According to the median MHR(0.47),MINOCA patients were classified into MHR≤0.47 group(79 cases)and MHR>0.47 group(79 cases). The smoking history and triglyceride(TG),the absolute value of monocytes(MO#)in MHR>0.47 group were higher than those in MHR≤0.47 group(P<0.05),and high-density lipoprotein cholesterol(HDL-C)was lower than that in MHR≤0.47 group(P<0.01). There was no statistical significance in the other indicators between the 2 groups(P>0.05). The incidence of MACE within 18 months after surgery in MHR>0.47 group was higher than that in MHR≤0.47 group(P<0.05). MHR>0.47,TG and low-density lipoprotein cholesterol(LDL-C)were independent risk factors for MACE occurrence in MINOCA patients for 18 months after surgery [odds ratios(OR)were 2.275,1.137 and 1.119,95% confidence intervals(CI)were 1.022-5.065,1.002-1.290 and 1.016-1.304,respectively,P<0.05]. The area under curve(AUC)of MHR in predicting MACE occurrence in MINOCA patients for 18 months after surgery was 0.745. The 5-year survival rate without MACE after surgery in MHR≤0.47 group was higher than that in MHR>0.47 group(Log-rank χ2= 6.905,P=0.009). Conclusions A high MHR is related to the occurrence of MACE in MINOCA patients. MHR has certain predictive value for MACE occurrence in MINOCA patients within 18 months after surgery,and may be used as a marker for predicting poor prognosis in MINOCA patients.
