Objective The correlation between Hb content,monocyte to high density lipoprotein cholesterol ratio(MHR)and post-stroke cognitive impairment(PSCI)was analyzed,and the application value of Hb and MHR in assisting diagnosis and evaluation of PSCI was discussed.Methods The clinical data of first-time stroke patients admitted to the Rehabilitation Department of the Second Affiliated Hospital of Nanjing Medical University from January 2021 to December 2022 were collected.The patients were divided into PSCI group and post-stroke no cognitive impairment(PSNCI)group by using MMSE scores.The differences in serum related indicators between the two groups were analyzed to find the risk factors of PSCI.Results There were a total of 81 stroke patients,including 43 in the PSCI group and 38 in the PSNCI group.There were no statistically significant differences in gender,age,history of hypertension,diabetes,smoking,drinking history,white blood cell count,neutrophil count,lymphocyte count,platelet count,total cholesterol,triglyceride,high density lipoprotein cholesterol and low density lipoprotein cholesterol between the two groups.The Hb content in PSCI group was significantly lower than that in PSNCI group,and the MHR was significantly higher than that in PSNCI group(P＜0.05).Spearman correlation analysis showed that Hb was positively correlated with MMSE score of stroke patients(rs = 0.353,P＜0.05),and MHR was negatively correlated with MMSE score of stroke patients(rs =-0.325,P＜0.05).According to whether PSCI occurred as the dependent variable,the analysis showed that lower Hb content and higher MHR were independent risk factors for PSCI(OR =1.056,95%CI:1.025-1.088,P＜0.05;OR =0.059,95%CI:0.006-0.577,P＜0.05).The area under ROC curve of Hb in predicting PSCI in stroke patients was 0.76(95%CI:0.656-0.865).The area under ROC curve of MHR for predicting PSCI in stroke patients was 0.62(95%CI:0.497-0.742).Conclusions Hb content and MHR are significantly correlated with PSCI.The decrease of Hb content and the increase of MHR are independent risk factors for PSCI.Hb content and MHR have certain reference value for the prediction and diagnosis of PSCI.

Objective:To explore the relationship between the triglyceride-glucose(TyG) index, the monocyte-to-high-density lipoprotein-cholesterol ratio(MHR) and the severity of coronary artery stenosis in patients with coronary artery heart disease(CHD).Methods:A total of 178 CHD patients who underwent coronary angiography at Hengshui People′s Hospital from June 2021 to June 2023 were retrospectively included. All patients were divided into four groups based on the Gensini score: no stenosis group(44 cases, Gensini score=0), mild stenosis group(48 cases, 1≤Gensini score≤20), moderate stenosis group(46 cases, 21≤Gensini score≤40), and severe stenosis group(40 cases, Gensini score>40). Logistic stepwise regression analysis, Pearson correlation analysis, and receiver operating characteristic(ROC) curve analysis were used to assess the correlation and diagnostic value among TyG index, MHR, and the degree of coronary artery stenosis in CHD patients. Results:At baseline, except for heart failure, arrhythmia, hypertension, diabetes, and alanine aminotransferase(ALT) ( P>0.05), the other indicators showed statistically significant differences among the four groups( P<0.05). Logistic stepwise regression analysis showed that smoking, increased TyG index, and MHR were independent risk factors for coronary artery stenosis. In addition, Pearson correlation analysis showed a positive correlation between TyG index( r=0.548, P=0.002) or MHR( r=0.595, P<0.001) and the degree of coronary artery stenosis. ROC curve analysis revealed that the area under the ROC curve, based on the combined coefficients of TyG index and MHR, was 0.851(95% CI 0.791-0.911), indicating the highest diagnostic efficacy for assessing the degree of coronary artery stenosis. Conclusion:TyG index and MHR are correlated with the severity of coronary artery stenosis, and the combination of TyG index and MHR has potential value as a biomarker for reflecting coronary artery stenosis.

In clinical practice, we need to develop new tools to identify the residual cardiovascular risk after acute coronary syndrome (ACS). This study aimed to evaluate whether the monocyte to high-density lipoprotein cholesterol ratio (MHR) variation (ΔMHR) obtained during hospital admission (MHR1) and repeated in the first outpatient evaluation (MHR2) is a predictor of major adverse cardiovascular events (MACE) after ACS. One hundred ninety-one patients admitted for ACS were prospectively included. The ΔMHR was calculated by subtracting MHR1 from MHR2. Patients were followed for 166±38 days in which the occurrence of MACE was observed. The best cutoff for ΔMHR was zero (0), and individuals were divided into two groups: ΔMHR<0 (n=113) and ΔMHR≥0 (n=78). The presence of MACE was higher in the ΔMHR≥0 (22%) than in the ΔMHR<0 (7%), with a hazard ratio (HR) of 3.96 (95% confidence interval [CI]: 1.74-8.99; P=0.0004). After adjusting for confounders, ΔMHR≥0 remained an independent MACE predictor with an adjusted HR of 3.13 (95%CI: 1.35-7.26, P=0.008). In conclusion, our study showed that ΔMHR was an independent MACE predictor after ACS. Thus, ΔMHR is a potential marker of residual cardiovascular risk after ACS.

Objective:To investigate the relationship between monocyte to high-density lipoprotein cholesterol ratio(MHR)and the thrombolysis in myocardial infarction(TIMI)risk score in elderly patients with ST elevation myocardial infarction(STEMI).Methods:This was a prospective clinical trial.A total of 152 patients admitted to Tangshan Workers' Hospital were enrolled between January 2015 to February 2018.Of these, 102 STEMI patients undergone primary percutaneous coronary intervention(PCI)were selected as the STEMI group and 50 patients with angiographically normal coronary arteries were selected as the control group.The STEMI patients were divided into two subgroups based on TIMI risk scores.The relationship between MHR and TIMI risk scores in patients with STEMI was analyzed.Logistic regression was used to analyze whether MHR could be used as an independent predictor of acute STEMI and high TIMI scores.Results:The MHR level was significantly higher in the STEMI group than in the control group( P<0.05)and was significantly higher in the high TIMI score subgroup than in the low TIMI score subgroup( P<0.05). In multivariate Logistic regression analysis, MHR was an independent predictor of high TIMI scores in acute STEMI(P<0.05). In correlation analysis, there was a significant positive correlation between MHR and TIMI score in STEMI patients( r=0.396, P<0.01). The ROC curve showed that the area under the curve of MHR was 0.815(95% CI: 0.734-0.896, Z=7.613, P<0.01). When the MHR optimal cut-off value was 2.380, the sensitivity was 55.22% and the specificity was 97.14%. Conclusions:MHR is significantly associated with the TIMI score in patients with STEMI.MHR may be used as a supplementary parameter for assessing the prognosis of STEMI patients.

Objective To investigate the prediction by intravascular ultrasound (IVUS) with monocyte to high density lipoprotein-cholesterol (HDL-C) ratio (MHR) of 12-month prognosis in patients with intermediate non-left main coronary lesions after percutaneous coronary intervention (PCI). Methods Patients with intermediate non-left main coronary lesions diagnosed by coronary angiography were tested of monocyte counts and HDL-C levels at admission with MHRs calculated. IVUS was used to examine plaque stability in target lesions. Patients were dviided into stable plaque group (n=44) and unstable plaque group (n=140) according to the IVUS results. PCI was then operated in patients with unstable plaque or with minimum lumen area<4 mm2. The major adverse cardiovascular events (MACE) were recorded during the follow-up period of 12 months after PCI. Results MHR was significantly higher in unstable plaque group than that in stable plaque group[(22.6±8.4) vs.(14.1±7.2),P<0.001]. Receiver-operating characteristic (ROC) analysis revealed that an MHR cut-off of 16.05 had 74.2％ sensitivity and 77.0％ specificity for prediction of 12-month MACE after PCI (AUC 0.78, 95％ CI 0.71–0.85, P<0.001). Besides, unstable plaque with MHR over 16.05 was an independent risk factor for 12-month MACE after PCI (adjusted HR 3.26, 95％ CI 2.48–4.14, P=0.020). Conclusions IVUS combined with MHR is a valuable index predicting the prognosiso f patients with intermediate non-left main coronary lesions who underwent PCI.
