Abstract
OBJECTIVE Inflammation is involved in the development and progression of nonalcoholic fatty liver disease (NAFLD). The monocyte to high-density lipoprotein cholesterol ratio (MHR) has emerged as a marker for various inflammation-related diseases. The aim of the present study was to investigate the association between the MHR and NAFLD in a population with childhood obesity. METHODS Based on hepatic ultrasound, a total of 504 children with obesity (357 with NAFLD and 147 without NAFLD) were included in the study. The correlation between the MHR and NAFLD risk factors was assessed by Pearson's and Spearman's analyses. Multivariate stepwise logistic regression analyses were conducted to explore the association between the MHR and the risk of NAFLD. RESULTS The MHR in patients with NAFLD was significantly greater than that in patients without NAFLD [0.52 (0.44-0.67) versus 0.44 (0.34-0.57), P<0.001]. Multivariate stepwise logistic regression analysis demonstrated that the MHR [odds ratio (OR): 1.033, 95% confidence interval (CI): 1.015-1.051; P<0.001] was an independent predictor of NAFLD in childhood obesity patients, as were age (OR: 1.205, 95% CI: 1.059-1.371; P=0.005], waist circumference [OR: 1.037, 95% CI: 1.008-1.067; P=0.012], and alanine transaminase [OR: 1.067, 95% CI: 1.045-1.089; P<0.001]. Additionally, MHR quartiles showed a significant positive association with the incidence of NAFLD after adjusting for potential confounding factors. CONCLUSION The present study showed that the MHR may serve as an available and useful indicator of NAFLD in individuals with childhood obesity.

Abstract
INTRODUCTION Acute pulmonary thromboembolism (PTE) is a life-threatening disease. Considering the availability and accessibility of assessing the serum lipids, this study aims to define the predictive value of lipid profile, as well as the history of lipid disorders, for the mortality of PTE patients. CONTENT Clinical studies, in which the relation of lipid profile, including triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and total cholesterol, as well as history of imbalance of lipids, with mortality of PTE patients was reported, were included. Non-English articles, reviews, letters, editorials, and non-English papers were excluded. A systematic search was conducted in PubMed, Embase, Scopus, and Web of Science databases. The risk of bias was assessed using the Joanna Briggs Institute (JBI) Critical Appraisal tools and CMA 4 was utilized for the quantitative synthesis. Out of 3,724 records, six studies were included in this systematic review. Lipid profile is suggested as a prognostic marker for survival in patients with PTE so higher initial serum HDL, LDL, and total cholesterol levels were associated with lower mortality rates in PTE patients. In addition, dyslipidemia was found to be associated with mortality of PTE patients. Based on the quantitative synthesis, there was a greater serum level of HDL in the survival group (standardized mean difference: -0.98; 95 % CI: -1.22 to -0.75; p-value<0.01). SUMMARY AND OUTLOOK Mortality is lower in PTE patients with greater serum lipid levels; therefore, the early prognosis of PTE may be ascertained by measuring serum lipids within the first 24 h of admission.

Abstract
Background Thyroid nodules, although mostly benign and symptomless, have a small chance of being cancerous, necessitating accurate diagnosis. This study aims to develop and validate a nomogram for differentiating malignant and non-malignant thyroid nodules in individuals with type 2 diabetes. Methods The study included 484 patients with both thyroid nodules and type 2 diabetes who underwent thyroid gland lobectomy at Wenzhou Medical University Hospital. Optimal cutoff values for continuous variables were determined using ROC curve analysis. Significant factors identified in univariable analysis were used to construct the nomogram. The monocyte-to-high-density lipoprotein cholesterol ratio (MHR) was visualized through a histogram and scatter diagram. Discriminatory power was assessed using ROC analysis, and calibration curves ensured consistency. Decision curve analysis (DCA) evaluated clinical benefits. Results The cohort was divided into a training group (70%) and an internal validation group (30%). The scatter diagram revealed a correlation between MHR levels and the proportion of goiter cases, with higher MHR levels associated with increased goiter incidence. The histogram showed higher average MHR levels in goiter patients compared to those with papillary thyroid carcinoma (PTC) in both groups. Multivariate logistic regression identified age, total cholesterol (TC), triglyceride (TG), fasting blood sugar (FSG), fibrinogen, lymphocyte-to-monocyte ratio (LMR), and MHR as independent predictive factors for malignancy in thyroid nodules with type 2 diabetes. The nomogram achieved high discrimination, with C-index values of 0.901 (training data set) and 0.760 (internal validation data set). Calibration curves displayed good agreement, and DCA demonstrated significant net clinical benefits. Conclusions MHR is associated with sex, serum cholesterol levels, and peripheral blood cell counts, making it a potential novel biomarker for differentiating between PTC and goiter in type 2 diabetes patients.

Abstract
OBJECTIVES The aim of this study was to examine the clinical significance of oxidative stress (OS)-related indices, including inflammatory markers and lipid and platelet (PLT) parameter, in coronary artery lesions (CALs) in Kawasaki disease (KD). METHODS Clinical data of 952 KD patients diagnosed between January 2019 and March 2022 were collected and divided into CAL and NCAL groups. All the KD patients were randomly divided into training set and verification set. The univariate analysis and multivariate logistic regression analysis of training set were used to identify the OS-related independent risk factors of CALs, which were then used to construct a predictive nomogram. Calibration curve and receiver operating characteristic curve were used to evaluate the performance of the model. The predictive nomogram was further validated on verification set. RESULTS In the training set, 137 KD patients (18.0%) showed CALs. C-reactive protein, serum amyloid A, PLT count, monocyte-to-high-density lipoprotein (HDL) ratio, and PLT-to-lymphocyte ratio were significantly higher, whereas HDL was lower in the CAL group than the NCAL group. Increased C-reactive protein, serum amyloid A, PLT, and decreased HDL were identified as independent risk factors. The nomogram constructed using these factors showed satisfactory calibration degree and discriminatory power (the area under the curve, 0.887). In the verification set, the area under the curve was 0.795. CONCLUSION The predictive nomogram constructed using 4 OS-related risk factors associated with CALs in patients with KD could be a useful tool for early diagnosis of CALs in KD.

Abstract
BACKGROUND The underlying pathology of isolated coronary artery ectasia (CE) has not been fully elucidated. OBJECTIVE We aimed to examine the relationship between the systemic immune inflammation index (Sıı), which corresponds to the multiplying of the neutrophil-to-lymphocyte ratio (NLR) and the platelet counts, and isolated CE. METHOD The retrospective study population included 200 patients with isolated CE, 200 consecutive with obstructive coronary artery disease, and 200 consecutive with a normal coronary artery angiogram. A 2-sided p-value of <0.05 was considered significant. RESULTS Sıı, NLR, platelet-to-lymphocyte ratio (PLR), and monocyte-to-high density lipoprotein cholesterol ratio (MHR) were significantly higher in the CE group compared with the other groups (all p<0.001). In multivariate analysis, Sıı (p<0.001, OR = 1.005, 95% CI =1.004-1.005) was found to be an independent predictor of isolated CE. In Receiver Operating Characteristic curve analysis, Sıı had a higher Area Under the Curve than NLR, PLR, and MHR. Sıı value of >517.35 has 79% sensitivity, 76% specificity for the prediction of the CE [AUC: 0.832, (p<0.001)]. Sıı had a significant correlation with the number of ectatic coronary arteries and Markis classification (r:0.214 p=0.002; r:-0.195, p=0.006, respectively). CONCLUSION To the best of our knowledge, this is the first study that Sıı was significantly associated with isolated CE presence and anatomical severity.

Abstract
Introduction: Transradial coronary angiography (TRA) is associated with a lower incidence of bleeding rate and access site complications and is associated with better outcomes compared to transfemoral angiography. However, radial artery spasm (RAS) is an important limitation of TRA procedures. Little is known regarding the relationship of serum vasodilator and inflammatory markers with RAS. Therefore, the present study aimed to investigate the association between serum adropin level and RAS in patients undergoing TRA. Methods: From February 2020 to January 2021, 39 consecutive patients who underwent elective daiagnostic TRA and experienced RAS during the procedure, and 42 age and sex matched controls who did not experience RAS were prospectively included into the study. The groups were compared regarding serum adropin levels and inflammatory markers. Results: Although adropin levels were found to be lower in the RAS group, this difference was not statistically significant between the the patients with RAS and controls (14.9 vs. 16.1, P=0.105). However, inflammatory parameters monocyte count and MHR (monocyte/HDL cholesterol ratio) were found to be statistically significantly higher in the RAS group compared to controls (P=0.001 and P=0.010, respectively). Moreover, a significant positive correlation was found between the monocyte count and RAS (r:0.360, P<0.001), and between MHR and RAS (r:0.288, P=0.009). Furthermore, multivariate analysis demonstrated that monocyte count (OR:1.671, 95%CI:1.312-2.094, P=0.001) and MHR (OR:1.116, 95%CI:1.054-1.448, P=0.022) were found to be independent predictors of RAS. Conclusion: Serum vasodilator and inflammatory markers may be useful in the prediction of RAS in patients undergoing TRA procedures.

Association of systemic immune-inflammation index (SII) with presence of isolated coronary artery ectasia. ARCHIVES OF MEDICAL SCIENCES. ATHEROSCLEROTIC DISEASES 2021; 6:e152-e157. [PMID: 34703943 PMCID: PMC8525247 DOI: 10.5114/amsad.2021.109253] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Accepted: 07/21/2021] [Indexed: 01/02/2023]
Abstract
Introduction The systemic immune-inflammation index (SII) has been developed based on the calculation of N×P/L (N, P and L represent neutrophil count, platelet count and lymphocyte count, respectively), and it is widely used as a marker of inflammation and an indicator of cardiovascular outcomes in patients with coronary artery disease. We examined a possible association between SII and the presence of isolated coronary artery ectasia (CAE). Material and methods In this retrospective case-control study, a total of 4400 patients who underwent elective coronary angiography between June 2015 and July 2020 were retrospectively screened. Following the application of exclusion criteria, our study population consisted of 139 CAE patients and 141 age- and gender-matched subjects who proved to have normal coronary angiograms. Results The median value of SII was found to be statistically significantly higher in patients with CAE (p < 0.01). SII level ≥ 809 measured on admission had 48% sensitivity and 82% specificity in predicting isolated CAE in ROC curve analysis. In this ROC analysis, the predictive powers of neutrophil-to-lymphocyte ratio (NLR) and SII in determining the presence of ectasia were compared, and the predictive power of SII was significantly stronger than N/L ratio (p = 0.003). In the multivariate analysis, hyperlipidaemia (OR = 1.978, 95% CI: 1.168–3.349, p = 0.01), smoking (OR = 1.86, 95% CI: 1.090–3.127, p = 0.023) N/L ratio (OR = 1.192, 95% CI: (1.114–1.997, p = 0.07) and SII (OR = 1.002, 95% CI: 1.001–1.003, p < 0.01) were independent predictors of the presence of isolated CAE. Conclusions SII is a readily available clinical laboratory value that is associated with the presence of isolated CAE. Our findings may indicate a common pathophysiological mechanism between CAE and coronary artery disease.

Abstract
PURPOSE The monocyte to high-density lipoprotein ratio (MHR) has been postulated to be a novel indicator associated with adverse cardiovascular outcomes in patients with coronary artery disease (CAD). These patients often have obstructive sleep apnea (OSA) and whether or not MHR may provide prognostic value for this comorbidity remains unclear. Therefore, we sought to explore the clinical value of MHR in evaluating OSA in patients with CAD. METHODS Consecutive patients with CAD were prospectively recruited and were assigned into four groups based on the quartiles of MHR. Portable monitoring for detecting nocturnal respiratory events was utilized to provide the diagnosis of OSA. Patients were defined as having OSA when respiratory event index ≥ 15 events/h. Univariate and multivariate regression analyses were used to explore the independent association between the levels of MHR and OSA. RESULTS A total of 1243 patients with CAD was included with a prevalence of OSA reaching 40% (n = 497). Patients with higher levels of MHR experienced increasing severity of OSA. In univariate analysis, MHR was a risk factor for OSA (odds ratio [OR] 1.90, 95% confidence interval [CI] 1.33-2.71, p < 0.001). Multivariate analysis showed that MHR was independently associated with the presence of OSA (OR 1.63, 95% CI 1.06-2.52, p = 0.027) after adjusting for possible confounding factors. CONCLUSIONS Elevated levels of MHR were independently associated with a higher likelihood of OSA in patients with CAD. MHR could be a screening tool and a risk biomarker of OSA in such patients.

Abstract
BACKGROUND Recent studies have identified monocyte to high-density lipoprotein ratio (MHR) as a simple, practical surrogate of atherosclerosis. Considering atherosclerosis is a major mechanism of coronary heart disease (CHD). The present study aims to evaluate the association between MHR and the prevalence of CHD. METHODS AND RESULTS The present cross-sectional work included 6442 participants (mean age: 59.57 years, 60.2% females), all of them were included from rural areas of northern China between October 2019 to April 2020. MHR was acquired as monocytes count divided by high-density lipoprotein concentration. Prevalent CHD researched 3.14%. After adjustment of sex, age, current drinking and smoking, BMI, WC, diabetes, hypertension, LDL-C, TG, eGFR, lipid-lowering therapy and cerebrovascular disease history, each standard deviation increase of MHR cast a 39.5% additional CHD risk. Furthermore, the top quartile of MHR had an additional 89.0% CHD risk than the bottom quartile. Besides, smooth curve fitting revealed a linear pattern of the association. Additionally, the stratified evaluation showed a robust correlation among the subgroups divided by CHD risk factors. Finally, area under the curve demonstrated an advancement when including MHR into common CHD risk factors (0.744 vs 0.761, p < 0.001). Consistently, reclassification analysis indicated the improvement from MHR (all P = 0.003). CONCLUSION Our work suggests the robust and linear relationship between MHR and the prevalent CHD in a general population, providing epidemiological evidence for laboratory studies. More importantly, the findings implicate the efficacy of MHR to be a potential indicator to identify the prevalent CHD.

Abstract
Introduction: Coronary artery ectasia (CAE) is one of the uncommon cardiovascular disorders and its prognosis is still debated. Objective: We aimed to review long-term follow-up data in patients with CAE and to evaluate the prognosis of CAE patients with coronary slow flow phenomenon (CSFP). Methods: This study had a prospective design and 143 patients with CAE were included. The angiographic and demographic characteristics were reviewed in detail. The patients were categorized, based on concomitant coronary artery stenosis detected by angiography, as CCAE group (n=87, ≥30% luminal stenosis) and ICAE group (n=56, <30% luminal stenosis) and also categorized by the coronary flow as CSFP group (n=51) and normal flow coronary ectasia - NCEA group (n=92). All patients were re-evaluated at 6-month intervals. Follow-up data, cardiovascular (CV) mortality, hospitalization and major adverse cardiac events (MACE) were collected. The level of statistical significance was set at 5%. Results: Patients were followed up for an average of 56.9±7.4 months. During the follow-up, statistically significant differences were found in hospitalization, CV mortality and MACE between the CCAE and ICAE groups (P=0.038, P=0.003, P=0.001, respectively). The CSFP and NCEA groups were also compared. There was a statistical difference with respect to hospitalization between the CFSP and NCEA groups (P=0.001), but no difference was observed in terms of MACE and CV mortality (P=0.793 and P=0.279). Conclusion: CSFP accompanying CAE may be a predictor of hospitalization. Significant atherosclerotic plaques coexisting with CAE may be predictive for MACE.

An elevated monocyte-to-high-density lipoprotein-cholesterol ratio is associated with mortality in patients with coronary artery disease who have undergone PCI. Biosci Rep 2021; 40:225998. [PMID: 32766711 PMCID: PMC7432996 DOI: 10.1042/bsr20201108] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Revised: 07/20/2020] [Accepted: 08/05/2020] [Indexed: 01/20/2023] Open
Abstract
Background: The aim of the present study was to investigate the association between the monocyte-to-high-density lipoprotein–cholesterol ratio (MHR) and the outcomes of patients with coronary artery disease (CAD) who were treated with percutaneous coronary intervention (PCI). Methods: A total of 5679 CAD patients from CORFCHD-PCI, a retrospective cohort study (identifier: ChiCTR-ORC-16010153), who underwent PCI were included in the study and divided into three tertiles according to their MHR values. The primary outcome was long-term mortality after PCI. The main secondary endpoints were stroke, readmission, and major adverse cardiovascular events (MACEs), defined as the combination of cardiac death, recurrent myocardial infarction, and target vessel reconstruction. The average follow-up time was 35.9 ± 22.6 months. Results: Patients were divided into three groups according to MHR tertiles: the first tertile (MHR < 0.4; n=1290), second tertile (MHR ≥ 0.4–0.61; n=1878) and third tertile (MHR > 0.61; n=1870). The all-cause mortality (ACM) incidence was significantly lower in the first and second tertiles than in the third tertile (adjusted HR = 0.658, [95% CI: 0.408–0.903], P=0.009 and HR = 0.712, [95% CI: 0.538–0.941], P=0.017, respectively). Cardiac mortality (CM) occurred in 235 patients: 60 (3.1%) in the first tertile group, 74 (3.9%) in the second tertile group and 101 (5.4%) in the third tertile group. There was a significant difference in the CM incidence between the first tertile group and the third tertile group (HR = 0.581, [95% CI: 0.406–0.832], P=0.003), and there was also a difference in the CM incidence between the second tertile group and the third tertile group (HR = 0.690, [95% CI: 0.506–0.940], P=0.019). Conclusion: The present study indicated that an increased MHR was independently associated with long-term mortality in CAD patients who have undergone PCI.

Abstract
BACKGROUND The importance of monocyte count-to-HDL-cholesterol ratio (MHR) in cardio- vascular diseases has been shown in various studies. Ascending aortic dilatation (AAD) is a common complication in the patients with bicuspid aortic valve. In this study, we aimed to investigate the relationship between MHR and the presence of aortic dilatation in the patients with bicuspid aortic valve. METHODS The study population included totally 347 patients with bicuspid aortic valve.169 patients with aortic dilatation (ascending aorta diameter ≥ 4.0 cm) and 178 patients with no aortic dilatation. Echocardiographic and laboratory measurement was done and compared between groups. RESULTS The mean age of the participants was 44.7 ± 15.4 years and average ascending aorta diameter was 3.2 ± 0.3 cm in dilatation negative group and 4.4 ± 0.4 cm in positive group. MHR was significantly increased in in patients with aortic dilatation. MHR and uric acid level was independently associated with the presence of aortic dilatation in the patients with bicuspid aortic valve. CONCLUSION We found a significant relationship between MHR and aortic dilatation in the patients with bicuspid aortic valve.

Abstract
Objective Monocyte to high density lipoprotein ratio (MHR) is a new instrument for giving notice inflammation, which plays a main role in schizophrenia. Thus, in this study, our goal was to investigate the possible association between MHR and schizophrenia. Methods The participants of this study consisted of 75 schizophrenia patients and 74 healthy individuals (control group). The Positive and Negative Syndrome Scale was used to collect data from the patient group. Complete blood count parameters and lipid profile were analyzed in all study participants. Results The patients with schizophrenia had higher MHR values (15.04 ± 3.31 in schizophrenia patients and 12.62 ± 2.99 in controls; p = 0.001). Monocyte counts and MHR of the schizophrenia patients were significantly higher than the control group. There was a significant and positive correlation between age, body mass index, severity of disease and MHR. Conclusion To our knowledge, this study was the first to demonstrate inflammatory markers such as MHR levels in schizophrenia patients. Both monocyte counts and MHR values in schizophrenia patients were higher than the control group. MHR might be an available and useful inflammatory marker to evaluate inflammation in schizophrenia patients.

Abstract
Hidradenitis suppurativa (HS) is a chronic, recurrent, and debilitating skin disease. Recent studies showed that inflammatory biomarkers, such as neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), Lymphocyte/HDL ratio (LHR), Neutrophil/HDL ratio (NHR), and Monocyte/HDL ratio (MHR) are an indicator of inflammatory diseases and may be associated with disease severity and disease activity. To investigate NLR, PLR, LHR, NHR, and MHR in HS patients. In addition, to compare erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), complete blood count, leukocyte profile, and biochemical parameters between the control and the patient group. Clinical and biochemical data of patients and healthy subjects were collected from medical records, retrospectively. In total, 166 patients with HS and 124 control subjects were included. We found no significant difference in NLR (P = .207) and PLR (P = .257). LHR (P < .001), NHR (P < .001), and MHR (P < .001) were significantly higher in the patient group. No positive correlation was found between any of these markers and disease severity according to Hurley staging system. However, MCV (Mean corpuscular volume), RDW (Red cell distribution width), and CRP showed a significant positive correlation with disease severity. Among these markers, only MHR was positively correlated with disease duration. Our study shows that CRP still maintains its value for HS patients compared to new inflammation markers. Unlike the studies in other inflammatory diseases, no significant relationship was found with most of these inflammatory parameters. MHR may be more useful in patients with HS as an indicator of inflammation compared to other parameters.

Abstract
Background Coronary artery aneurysm (CAA) and coronary artery ectasia (CAE) may be two different types of coronary artery dilatation with unknown etiology. This study aimed to compare the differences between CAA and CAE and to investigate their pathogenesis and the necessity of antiplatelet therapy. Methods One hundred patients each with confirmed CAA, CAE, and normal coronary artery (NCA) from September 2017 to July 2019 were included. All patients completed examinations of the ankle-brachial index (ABI), pulse wave rate, and carotid ultrasonography; and were tested for routine blood, lipid, and immune parameters. Blood samples were collected 1 week after the withdrawal of antiplatelet drugs, and vascular inflammatory indexes, platelet activation indexes, thromboelastography, and the platelet aggregation rate were measured. Analysis of variance and the chi-square or Fisher exact test were used for statistical analysis. Results The perinuclear anti-neutrophil cytoplasmic antibody (ANCA), endothelial-1, matrix metalloproteinase-9, and tumor necrosis factor-α were significantly higher in CAE than in NCA, while cytoplasmic ANCA was appreciably higher in CAE than in CAA (P<0.05). Myeloperoxidase and growth/differentiation factor-15 were significantly higher in CAE than in CAA and NCA (P<0.05). ABI was significantly lower in CAA and CAE than in NCA (P<0.05), low-density lipoprotein/high-density lipoprotein was significantly higher in CAA than in NCA (P<0.05), and the detection rate of carotid artery thickening was significantly higher in CAA than in CAE and NCA (P<0.05). The Gensini and SYNTAX scores were significantly higher in CAA than in CAE (P<0.05). The percentages of CD62P and PAC-1 were higher in CAA and CAE than in NCA (P<0.05). The arachidonic acid aggregation rate in CAA and adenosine 5'-diphosphate aggregation rate in CAE were significantly higher than in NCA (P<0.05). The values of thrombin formation time and reaction time were significantly lower in CAE than in NCA (P<0.05), and the α angle was significantly higher in CAE than in NCA. Conclusions CAE was closely related to inflammation, whereas CAA was closely related to atherosclerosis. Platelet activation was present in both diseases; therefore, antiplatelet therapy is recommended.

Abstract
OBJECTIVE Inflammation has been suggested as a potential mechanism in the pathogenesis of arrhythmia. Hemogram parameters such as monocyte count to high-density lipoprotein cholesterol ratio (MHR), neutrophil/lymphocyte ratio (NLR), and monocyte/lymphocyte ratio (MLR) have been considered to be markers of inflammation and new cardiovascular risk predictors. This retrospective study aimed to investigate the relationship between MHR, NLR, and MLR in patients with paroxysmal supraventricular tachycardia (PSVT). METHODS A retrospective study conducted at a university hospital in Bolu, Turkey, between 2017 and 2019. Our study included 196 patients who underwent electrophysiological study (EPS) due to palpitation or documented PSVT on electrocardiography (ECG). Patients having documented atrioventricular nodal re-entrant tachycardia (AVNRT) on ECG or inducible AVNRT on EPS were included in the PSVT group (n=130), and patients with palpitation but without inducible arrhythmia on EPS (n=66) were included in the control group. Routine biochemical and hemogram tests were performed before the EPS procedure. RESULTS When hemogram parameters were compared, there was no statistically significant difference in MHR values [0.010 (0.001-0.030) vs 0.010 (0.001-0.020) p =0.67]. Additionally, both NLR [2.21(0.74-11.36) vs 1.98(0.72-24.87) p=0.13] and MLR [0.25 (0.03-1.05) vs 0.24(0.07-1.39) p=0.41] were not statistically significant between the two groups. CONCLUSION There is no significant difference in PSVT patients regarding hemogram parameters including white blood cell subtypes, MLR, NLR, and MHR. Therefore the evaluation of hemogram parameters may not be clinically relevant for PSVT patients.

Abstract
PURPOSE Aim of this study is to investigate effectiveness of the monocyte to HDL cholesterol ratio in patients diagnosed with pulmonary embolism for predicting intra-hospital mortality. METHOD A total of 269 patients diagnosed with pulmonary embolism in the emergency clinic were included in the study. Study was conducted retrospectively. Pulmonary Embolism Severity Index (PESI), Monocyte count and high density lipoprotein cholesterol (HDL) values were determined. MHR values of the patients were calculated. SPSS 26 package program was used to investigate the effectiveness of MHR in predicting mortality. FINDINGS Mean age of the patients was 64.51 ± 12.4 years. PESI, Number of monocytes and MHR were significantly higher in the group with mortality than the group without mortality (p < .05). HDL values were significantly lower (p < .05) in mortality group. Sensitivity of MHR 19 cut off value was 89.3%, and its specificity was 82.0%. CONCLUSION Use of predictors for mortality estimation in patients diagnosed with acute pulmonary embolism is important for faster administration of treatment modalities. We think MHR values can be used as a strong predictor according to the hemogram parameters and biochemical results.

Abstract
Vitamin B12 deficiency may have indirect cardiovascular effects in addition to hematological and neuropsychiatric symptoms. It was shown that the monocyte count-to-high density lipoprotein cholesterol (HDL-C) ratio (MHR) is a novel cardiovascular marker. In this study, the aim was to evaluate whether MHR was high in patients with vitamin B12 deficiency and its relationship with cardiometabolic risk factors. The study included 128 patients diagnosed with vitamin B12 deficiency and 93 healthy controls. Patients with vitamin B12 deficiency had significantly higher systolic blood pressure (SBP), diastolic blood pressure (DBP), MHR, C-reactive protein (CRP) and uric acid levels compared with the controls (median 139 vs 115 mmHg, p < 0.001; 80 vs 70 mmHg, p < 0.001; 14.2 vs 9.5, p < 0.001; 10.2 vs 4 mg/dl p < 0.001; 6.68 vs 4.8 mg/dl, p < 0.001 respectively). The prevalence of left ventricular hypertrophy was higher in vitamin B12 deficiency group (43.8%) than the control group (8.6%) (p < 0.001). In vitamin B12 deficiency group, a positive correlation was detected between MHR and SBP, CRP and uric acid (p < 0.001 r:0.34, p < 0.001 r:0.30, p < 0.001 r:0.5, respectively) and a significant negative correlation was detected between MHR and T-CHOL, LDL, HDL and B12 (p < 0.001 r: -0.39, p < 0.001 r: -0.34, p < 0.001 r: -0.57, p < 0.04 r: -0.17, respectively). MHR was high in vitamin B12 deficiency group, and correlated with the cardiometabolic risk factors in this group, which were SBP, CRP, uric acid and HDL. In conclusion, MRH, which can be easily calculated in clinical practice, can be a useful marker to assess cardiovascular risk in patients with vitamin B12 deficiency.

Abstract
Background Coronary artery ectasia (CAE) is the limitation or diffuse expansion of the epicardial coronary artery. In most cases, the pathological basis of CAE is considered to be coronary atherosclerosis. Previous studies have confirmed the association between Apelin and arterial atherosclerosis. Apelin-13 (AP-13) is the main serum Apelin subtype in healthy humans, however the effect of serum AP-13 on CAE has yet to be elucidated. In this research, we analysed the relationship between serum AP-13 levels and CAE. Methods One hundred and forty subjects who underwent selective diagnostic coronary angiography were enrolled in this research. We identified and included 40 patients with CAE as the study subjects. Another 50 patients with coronary artery disease (CAD) were randomly selected as the CAD group, and 50 patients without CAD were selected as the normal control group. Serum AP-13 levels were collected for all subjects. Results There were no statistically significant differences in baseline data except for gender. After unconditional logistic regression analysis, AP-13 and HDL-c were independent risk factors for CAE (both p < 0.05). The serum AP-13 level was significantly lower in the CAE patients than in the CAD patients (1.86 ± 0.59 vs. 2.49 ± 1.19 ng/mL, p = 0.004). Serum AP-13 levels were slightly lower in the CAD patients than in the controls (2.49 ± 1.19 vs. 3.12 ± 1.64, p = 0.079). Conclusions Apelin-13 may have an effect on the development of CAE. Further studies should be performed to elucidate the possible pathogenic role of AP-13 in CAE.

[PMID: 32247314 PMCID: PMC7126405 DOI: 10.1186/s12944-020-01238-2] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2019] [Accepted: 03/13/2020] [Indexed: 01/31/2023] Open
Abstract
Background The importance of the lipid-related biomarkers has been implicated in the pathological process and prognosis of acute myocardial infarction (AMI). Our work was conducted to discuss and compare the predictive ability of the neutrophil to high-density lipoprotein cholesterol (HDL-C) ratio (NHR) with other existing prognostic indices, for instance, the monocyte to HDL-C ratio (MHR) and the low-density lipoprotein cholesterol (LDL-C) to HDL-C ratio (LDL-C/HDL-C) in elderly patients with AMI. Methods Our population was 528 consecutive elderly AMI patients (65–85 years) who were enrolled from Tongji Hospital and grouped according to the cutoff points which were depicted by the receiver operating characteristic (ROC). The Kaplan-Meier curves were plotted with the survival data from the follow-up to investigate the difference between cutoff point-determined groups. Moreover, we assessed the impact of NHR, MHR, LDL-C/HDL-C on the long-term mortality and recurrent myocardial infarction (RMI) with Cox proportional hazard models. Results Mean duration of follow-up was 673.85 ± 14.32 days (median 679.50 days). According to ROC curve analysis, NHR ≥ 5.74, MHR ≥ 0.67, LDL-C/HDL-C ≥ 3.57 were regarded as high-risk groups. Kaplan-Meier analysis resulted that the high-NHR, high-MHR and high-LDL-C/HDL-C groups presented higher mortality and RMI rate than the corresponding low-risk groups in predicting the long-term clinical outcomes (log-rank test: all P < 0.050). In multivariate analysis, compared with MHR and LDL-C/HDL-C, only NHR was still recognized as a latent predictor for long-term mortality (harzard ratio [HR]: 1.96, 95% confidence interval [CI]: 1.02 to 3.75, P = 0.044) and long-term RMI (HR: 2.23, 95% CI: 1.04 to 4.79, P = 0.040). Furthermore, the positive correlation between NHR and Gensini score (r = 0.15, P < 0.001) indicated that NHR was relevant to the severity of coronary artery to some extent. Conclusions NHR, a novel laboratory marker, might be a predictor of the long-term clinical outcomes of elderly patients with AMI, which was superior to MHR and LDL-C/HDL-C.

Monocyte to High-Density Lipoprotein Ratio (MHR) as a predictor of mortality and Major Adverse Cardiovascular Events (MACE) among ST Elevation Myocardial Infarction (STEMI) patients undergoing primary percutaneous coronary intervention: a meta-analysis. Lipids Health Dis 2020; 19:55. [PMID: 32216795 PMCID: PMC7098114 DOI: 10.1186/s12944-020-01242-6] [Citation(s) in RCA: 34] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2019] [Accepted: 03/18/2020] [Indexed: 01/18/2023] Open
Abstract
Background Monocyte to High Density Lipoprotein Ratio (MHR) is a new marker that has been associated with major adverse cardiovascular outcomes among STEMI patients. We sought to strengthen the association between MHR and mortality and major adverse cardiovascular events (MACEs) among STEMI patients who underwent primary percutaneous coronary intervention. Methods Studies were included if they satisfied the following criteria:1) Observational Studies; 2) Adult patients with ST-elevation Myocardial Infarction (STEMI) who underwent primary percutaneous intervention (PCI); and 3) Reported data on mortality and major adverse cardiovascular events. Using MEDLINE, Clinical Key, Science Direct, Scopus, and Cochrane Central Register of Controlled Trials databases, a search for eligible studies was conducted until September 2017. Our primary outcome of interest was all-cause cardiovascular (CV) mortality. We also investigated the association between MHR and major adverse cardiovascular events (MACEs). Results We identified 3 studies involving 2793 STEMI patients, showing that in STEMI patients who underwent primary PCI, a high admission MHR is associated with a significantly higher in-hospital mortality [RR 4.71, (95% CI 2.36 to 9.39, p < 0.00001] and in-hospital MACE [RR 1.90, (95% CI 1.44 to 2.50), p < 0.00001]. This significant association was not observed in long term mortality or MACE. Conclusion A high admission MHR among STEMI patients who underwent primary PCI is associated with a higher in-hospital mortality and MACE. This novel marker can be used as an inexpensive and readily available tool for risk stratification.

Abstract
BACKGROUND Monocyte to high-density lipoprotein cholesterol ratio (MHR) is a novel inflammatory marker that has been used to predict various inflammation-related diseases. This study aims to explore the association between MHR and prevalent hyperuricemia in a rural Chinese population. METHODS 8163 eligible participants (mean age: 54.13 years, males: 45.71%) from northeast China were enrolled in this cross-sectional study between 2012 to 2013. MHR was determined as blood monocyte count ratio to high-density lipoprotein cholesterol concentration. RESULTS The prevalence of hyperuricemia was 12.86%. After adjusting for potential confounding factors, per SD increase of MHR caused a 25.2% additional risk for hyperuricemia, and the top quartile of MHR had an 82.9% increased risk for hyperuricemia compared with the bottom quartile. Additionally, smooth curve fitting and subgroup analyses showed a linear and robust association between MHR and prevalent hyperuricemia respectively. Finally, after introducing MHR into the established model of risk factors, the AUC displayed a significant improvement (0.718 vs 0.724, p = 0.008). Furthermore, Category-free net reclassification improvement (0.160, 95% CI: 0.096-0.224, P < 0.001) and integrated discrimination improvement (0.003, 95% CI: 0.002-0.005, P < 0.001) also demonstrated significant improvements. CONCLUSIONS The present study suggests that MHR was positively and independently correlated with prevalent hyperuricemia among rural Chinese adults. Our results also implicate an important value for MHR in optimizing the risk stratification of hyperuricemia.

Abstract
Background Systemic inflammation may be involved in the formation and progression of thyroid nodule (TN). The aim of this large-scale study was to investigate the association of several simple inflammatory markers with the presence and size of TN. Methods A total of 133,698 adults were included for the current analysis. The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and monocyte-to-high-density lipoprotein cholesterol ratio (MHR) were calculated. The logistic regression was used to explore the association of the four markers with the presence and size of TN. Results The prevalence of TN was 55.1% among females and 44% among males; 13% of women and 8% of men had non-micronodule. In women, MHR and PLR were significantly associated with the presence of TN and non-micronodule; in men, MHR and NLR were significantly associated with the presence of TN and non-micronodule. Conclusions As a low-cost, simple, and reproducible inflammatory marker, MHR is strongly associated with the presence and size of TN irrespective of the gender.

Abstract
Background The relation between monocyte to high-density lipoprotein cholesterol ratio (MHR) and coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI) remains controversial. The present study aims to assess the prognostic value of MHR in patients with CAD who underwent PCI. Methods A total of 673 CAD patients were retrospectively enrolled and divided into four groups according to MHR values. Multivariate Cox regression analysis was performed to study the effects of different variables to clinical outcomes reported as major adverse cardiac events (MACE) and all-cause mortality (ACM). Results In a multivariate Cox analysis, after adjustment of other confounders, MHR was found to be an independent predictor of ACM (HR: 3.655; 95% CI: 1.170–11.419, P = 0.026) and MACE (HR =2.390, 95% CI 1.379–4.143, p < 0.002). Having a MHR in the third and fourth quartile were associated with a 2.83-fold and 3.26 -flod increased risk of MACE. Conclusions MHR is an independent predictor of ACM and MACE in CAD patients undergoing PCI.

Abstract
Aim: We aimed to compare the monocyte to HDL-cholesterol ratio (MHR) of nondipper hypertension (NDHT) and dipper hypertension patients. Patients & methods: A total of 162 patients were included in the study. Patients were grouped as dipper and nondipper according to 24-h ambulatory blood pressure recordings. Results: The MHR was significantly higher in nondipper hypertension group compared with control (p < 0.001) and dipper hypertension groups (p = 0.03). MHR, hs-CRP and red-cell distribution width (RDW) were independent predictors of nondipper hypertension. Area under the curve was 0.62 (p = 0.034) for MHR and 0.61 (p = 0.012) for hs-CRP in the ROC analysis. Conclusion: MHR has elevated levels in NDHT patients. Increased levels of MHR may evaluate as increased risk of cardiovascular events in NDHT patients.

Abstract
Background Monocyte to high-density lipoprotein cholesterol ratio (MHR) is a recently emerged measure of inflammation and oxidative stress and has been used to predict multiple cardiovascular abnormalities, but data relative to ischemic stroke are lacking. The goal of this study was to estimate the associations of MHR and prevalent ischemic stroke among a large cohort of general Chinese population. Method The study analyzed 8148 individuals (mean age: 54.1 years; 45.7% males) enrolled in a cross-sectional population-based Northeast China Rural Cardiovascular Health Study (NCRCHS). We identified 194 patients admitted from January and August 2013 with ischemic stroke. Results After adjustment for age, sex, and potential confounders, each standard deviation (SD) increment of MHR was predictive to a greater odd of ischemic stroke (odds ratio, 1.276; 95% confidence interval [CI], 1.082–1.504), with subjects in the highest quartile of MHR levels having a 1.6-fold higher risk of prevalent ischemic stroke (95% CI, 1.045–2.524) as compared with those in the lowest quartile. Moreover, smoothing curve showed a linear positive pattern of this association. The area under the curve (AUC) significantly increased (P = 0.042) to 0.808 (95% CI, 0.779–0.837) when the combined MHR was added to the baseline logistic regression model with ischemic stroke risk factors. Also, MHR (0.004) significantly improved integrated discrimination improvement when added to the baseline model. Conclusions The present study demonstrated for the first time a linear relation between MHR levels and the odds of ischemic stroke in a large community-based population. The MHR, a marker of high atherosclerotic burden, demonstrated incremental predictive value over traditional clinical risk factors, thus providing clinical utility in risk stratification in subjects presenting with ischemic stroke. These findings had implications for strategies aimed at lowering MHR to prevent adverse cardiovascular and cerebrovascular outcomes.

Abstract
Background Peripartum cardiomyopathy (PPCM) is a rare but potentially life-threatening complication of pregnancy. There is limited data regarding the predictors of persistent left ventricular (LV) systolic dysfunction. Recently, monocyte-to-high density lipoprotein (HDL) cholesterol ratio (MHR) has emerged as a novel indicator of inflammation and oxidative stress. We aimed to assess the predictive value of MHR on LV recovery in patients with PPCM. Methods A total of 64 patients with PPCM who admitted to our tertiary reference hospital between 2009 and 2017 were retrospectively analyzed in this study. Demographic and clinical data, laboratory parameters and echocardiographic findings were recorded. The duration of follow-up was at least 12 months after diagnosis for all participants. Recovery of LV systolic function was defined as the presence of LV ejection fraction (LV EF) > 45%. Univariate analysis was used to determine the significant predictors of persistent LV systolic dysfunction (non-recovery). A receiver operating characteristic (ROC) curve was used to establish the cut-off values for predictors. Results The mean follow-up duration was 72.1 ± 5.5 months. Of the 64 patients, 35 (55%) had persistent LVSD at their last follow-up while 29 (45%) showed LV EF improvement. The baseline MHR levels were significantly higher in the non-recovery group (P < 0.001). In univariate analysis, increased MHR levels (odds ratio:1.17; 95% confidence interval, 1.01–1.35; P < 0.001) significantly predicted LV non-recovery. Using a cut-off level of 9.73, MHR predicted persistent LV systolic dysfunction with a sensitivity of 89% and specificity of 79%. Besides, lower baseline LVEF increased WBC and CRP levels were identified as predictors of LV non-recovery. Conclusions Our data firstly indicated that elevated MHR was a significant predictor of persistent LV systolic dysfunction in PPCM. The MHR might contribute to determining high-risk patients with PPCM.

Abstract
Coronary artery ectasia (CAE) can present as an acute coronary syndrome (ACS) with a high clot burden in ectatic coronary arteries. Thrombectomy with intracoronary thrombolysis often does not ensure immediate blood flow. Also, there have not been clear guidelines regarding long-term management in such cases. A 40-year-old male presented with anginal chest discomfort and a working diagnosis of non-ST elevation myocardial infarction (NSTEMI) was made. The initial angiography showed thrombotic occlusion of several large and ectatic coronary arteries with visibly swirling blood flow. The culprit lesions were treated with balloon angioplasty and multiple rounds of thrombectomy yielding red thrombi. Interestingly, the post-intervention antegrade flow decreased in both vessels (Thrombolysis in Myocardial Infarction (TIMI) score: 0), possibly because of the distal migration of the clots. Peri-procedure, the patient received two boluses of eptifibatide, 180 mcg/kg each, followed by a continuous infusion of 2 mcg/kg/minute for 18 hours. Afterward, the patient was started on ticagrelor and continued on daily aspirin, high-intensity statin, beta blocker, and Coumadin® with heparin bridge. During the one year follow-up period, the Coumadin was switched to rivaroxaban, ticagrelor was stopped after six months, and the patient was continued on guideline-directed medical therapy (GDMT) for coronary artery disease (CAD) with favorable outcomes. The presented case gives us an insight into not only the intra-procedural but also the post-procedural management of ACS in the setting of CAE, and that is thrombectomy alone followed by longer duration oral anticoagulation in addition to GDMT for CAD. However, it will be interesting to see future studies aimed toward defining the duration as well as the choice of anticoagulation, i.e., dual antiplatelet therapy (DAPT) alone or in combination with warfarin/novel oral anticoagulants (NOACs).

Assessment of the Relationship between Monocyte to High-Density Lipoprotein Ratio and Myocardial Bridge. Arq Bras Cardiol 2019; 112:12-17. [PMID: 30570069 PMCID: PMC6317631 DOI: 10.5935/abc.20180253] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2018] [Revised: 06/19/2018] [Accepted: 08/02/2018] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND Assessing the monocyte to high-density lipoprotein ratio (MHR) is a new tool for predicting inflamation, which plays a major role in atherosclerosis. Myocardial bridge (MB) is thought to be a benign condition with development of atherosclerosis, particularly at the proximal segment of the brigde. OBJECTIVE To evaluate the relationhip between MHR and the presence of MB. METHODS We consecutively scanned patients referred for coronary angiography between January 2013- December 2016, and a total of 160 patients who had a MB and normal coronary artery were enrolled in the study. The patients' angiographic, demographic and clinic characteristics of the patients were reviewed from medical records. Monocytes and HDL-cholesterols were measured via complete blood count. MHR was calculated as the ratio of the absolute monocyte count to the HDL-cholesterol value. MHR values were divided into three tertiles as follows: lower (8.25 ± 1.61), moderate (13.11 ± 1.46), and higher (21.21 ± 4.30) tertile. A p-value of < 0.05 was considered significant. RESULTS MHR was significantly higher in the MB group compared to the control group with normal coronary arteries. We found the frequency of MB (p = 0.002) to increase as the MHR tertiles rose. The Monocyte-HDL ratio with a cut-point of 13.35 had 59% sensitivity and 65.0% specificity (ROC area under curve: 0.687, 95% CI: 0.606-0.769, p < 0.001) in accurately predicting a MB diagnosis. In the multivariate analysis, MHR (p = 0.013) was found to be a significant independent predictor of the presence of MB, after adjusting for other risk factors. CONCLUSION The present study revealed a significant correlation between MHR and MB.

Abstract
Inflammation and lipid accumulation are two basic hallmarks of atherosclerosis as a chronic disease. Inflammation not only is a local response but can also be considered as a systemic process followed by an elevation of inflammatory mediators. Monocytes are a major source of proinflammatory species during atherogenesis. In atherosclerosis, modified low-density lipoproteins (LDLs) are removed by macrophages; these are recruited in the vessel wall, inducing the release of inflammatory cytokines in inflamed tissue. Hence, inflammatory cholesterol ester-loaded plaque is generated. High-density lipoprotein-cholesterol (HDL-C) exhibits antiatherosclerotic effects by neutralizing the proinflammatory and pro-oxidant effects of monocytes via inhibiting the migration of macrophages and LDL oxidation in addition to the efflux of cholesterol from these cells. Furthermore, HDL plays a role in suppressing the activation of monocytes and proliferation-differentiation of monocyte progenitor cells. Thus, accumulation of monocytes and reduction of HDL-C may participate in atherosclerosis and cardiovascular diseases (CVD). Given that the relationship between the high number of monocytes and low HDL-C levels has been reported in inflammatory disorders, this review focused on understanding whether the monocyte-to-HDL ratio could be a convenient marker to predict atherosclerosis development and progression, hallmarks of CV events, instead of the individual monocyte count or HDL-C level.

Abstract
Coronary artery ectasia describes a local or diffuse dilatation of the epicardial coronary arteries. This review summarizes the molecular and cellular mechanisms involved in the pathogenesis of coronary artery ectasia. Better identification of the pathophysiologic steps will shed light into the clinical significance and may have direct implications for the management strategies of this disease. Additionally, understanding the underlying etiology may help to improve treatment modalities specific to coronary artery ectasia.

Abstract
AIM The purpose of this study was to evaluate the relationship between monocyte to high-density lipoprotein cholesterol ratio (MHR) and carotid atherosclerostic plaque in patients with systemic lupus erythematosus (SLE). METHODS A total of 214 SLE patients were divided into two groups according to the results of ultrasonic examination: carotid arterial atherosclerotic plaque groups and noncarotid arterial atherosclerosis groups. RESULTS The values of monocyte to high-density lipoprotein-cholesterol ratio (MHR) increase in carotid arterial atherosclerotic plaque groups compared with noncarotid arterial atherosclerosis groups (0.32 ± 0.18 vs 0.26 ± 0.15; p = 0.015). There was a significant correlation between MHR and carotid artery intima-media thickness (r = 0.228; p = 0.001) in patients with SLE. CONCLUSION Our study suggests that the values of MHR could be a marker to assess carotid artery intima-media thickness in patients with SLE.

Abstract
OBJECTIVES This study was designed to investigate the impact of renin-angiotensin system blockade (RASB) therapy with angiotensin-converting enzyme inhibitors or angiotensin-receptor blockers on the outcomes of coronary artery ectasia (CAE). METHODS The CAE patients identified by coronary angiography from our center were consecutively enrolled. We obtained the baseline discharge prescription of RASB from the medical records system and conducted follow-up through telephone interviews. Cox regression models, propensity score and subgroup analysis were used to assess the impact of RASB on all-cause mortality and non-fatal myocardial infarction. Both the unadjusted and adjusted Kaplan-Meier curves stratified by RASB therapy were plotted. RESULTS There were 595 patients with CAE in total and 333 (56.0%) were prescribed RASB therapy. Over a 2 year follow-up time, 16 all-cause deaths and 10 non-fatal myocardial infarctions were identified. Those patients treated with RASB had a significantly lower all-cause mortality and non-fatal myocardial infarction rate with an adjusted hazard ratio of 0.32 (95% confidence interval: 0.13 to 0.77, p = .011). The outcome benefits of RASB therapy were further confirmed in the propensity score analysis and subgroup analysis. CONCLUSIONS This observational study suggests that RASB therapy is associated with a lower risk of all-cause mortality and non-fatal myocardial infarction in patients with CAE.

Abstract
BACKGROUND Obstructive sleep apnea syndrome (OSAS) is an independent risk factor for cardiovascular disease (CVD). Although monocyte to high-density lipoprotein cholesterol ratio (MHR) is increasingly being implicated in cardiovascular morbidity and mortality, no study has attempted to determine the role of MHR in cardiovascular morbidity of patients with OSAS. We aimed to investigate the association between MHR and CVD in patients with OSAS and the relationship between severity of OSAS, polysomnographic parameters, and MHR. METHODS In this cohort study, patients who had undergone a full-night polysomnography for the diagnosis of OSAS were recruited. Included patients were grouped according to the apnea-hypopnea index (AHI) as mild (5-15), moderate (15-30), and severe (>30) OSAS. Patients with AHI < 5 served as the control group. The presence of heart failure, coronary artery disease, or arrhythmia was defined as CVD. RESULTS A total of 1050 patients were included (131 controls, 222 mild, 228 moderate, and 469 severe OSAS). The severe group had higher MHR compared with the control and other OSAS groups (9.99, 12.11, 13.65, and 20.67 in control, mild, moderate, and severe OSAS groups, respectively, P < .001). The MHRs were significantly correlated with AHI, oxygen desaturation index, and minimum O2 saturation values ( P < .001). Values of MHR were significantly higher in patients with CVD compared with those without ( P < .001). Multiple regression analysis demonstrated that MHR is an independent predictor of CVD. CONCLUSION The MHR is strongly associated with CVD and the severity of OSAS and might be used as a biomarker to predict CVD in patients with OSAS.

Abstract
Background Oxidation and inflammation play significant roles in the pathogenesis of coronary artery diseases. Monocyte count to high-density lipoprotein (HDL) cholesterol ratio (MHR) is a new marker and has revealed as an indicator of inflammation in the literature. The present study aimed to search the effect of MHR on in-stent restenosis (ISR) in patients with stable or unstable angina pectoris undergoing bare-metal stent (BMS) implantation. Methods A total of 468 consecutive stable or unstable angina pectoris patients (mean age 60.3 ± 10.1 and 70 % men) who had undergone successful BMS implantation were included the study. Serum samples were obtained before the procedure. Results The mean period between two coronary angiography procedures was 14 ± 7.9 months. The baseline MHR levels were significantly higher in patients that had ISR (odds ratio, 3.64; 95 % confidence interval, 2.45- 4.84; P < 0.001). Stent diameter, the time between the two coronary angiographic studies, uric acid and MHR levels emerged as independent predictors of ISR. Conclusions Our results indicate that elevated MHR is an independent and powerful predictor of ISR in patients with stable or unstable angina pectoris who underwent successful BMS implantation.

Abstract
AIM To determine the association of monocyte count-to-high-density lipoprotein (HDL)-cholesterol ratio, a recently emerged inflammatory marker, with abdominal aortic aneurysm (AAA) size. PATIENTS & METHODS A total of 120 asymptomatic AAA subjects (99 male, mean age: 67.1 ± 10.2 years) were enrolled into the study. All data were compared between patients with low and high admission monocyte/HDL ratio. Multivariate linear regression analysis was performed to study the relationship between different variables and AAA size. RESULTS Compared to patients with below-median monocyte/HDL ratio, aneurysm diameter was significantly higher in above-median monocyte/HDL ratio group (54.3 ± 10.6 mm vs 62.0 ± 12.4 mm, p < 0.001, respectively). Hypertension, coronary artery disease, monocyte/HDL ratio and C-reactive protein were independently associated with AAA diameter. CONCLUSION Monocyte/HDL ratio is independently associated with AAA size.

Abstract
Aim: The aim of the present study was to investigate the predictive value of preprocedural monocyte count-to-high-density lipoprotein cholesterol ratio (MHR) on development of in-stent restenosis in patients undergoing coronary bare-metal stent (BMS) implantation. Patients & methods: Data from 705 patients who had undergone BMS implantation and additional control coronary angiography were analyzed. Results: Patients were divided into three tertiles based on preprocedural MHR. Restenosis occurred in 59 patients (25%) in the lowest tertile, 84 (35%) in the middle tertile and 117 (50%) in the highest MHR tertile (p < 0.001). Using multiple logistic regression analysis, smoking, diabetes mellitus, stent length, preprocedural MHR and C-reactive protein levels emerged as independent predictors of in-stent restenosis. Conclusion: High preprocedural MHR is related to BMS restenosis.

Abstract
Intracoronary thrombus burden is associated with some adverse events and poor prognosis in patients with ST-segment elevation myocardial infarction (STEMI). Identifying predictors of the intracoronary thrombus burden may contribute to the management of STEMI. In this study, we evaluated whether monocyte count to high-density lipoprotein cholesterol ratio (MHR) is a predictor of intracoronary thrombus burden in patients with STEMI. The study population consisted of 414 patients with STEMI who underwent primary percutaneous coronary intervention (PCI). Angiographic thrombus burden was classified based on thrombolysis in myocardial infarction (TIMI) thrombus grades. The patients were grouped into 2 categories of low thrombus burden and high thrombus burden. The MHR was significantly higher in the high thrombus burden group compared with the low thrombus group (16.0 [9.2-22.1] vs 25.4 [13.5-44.6]; P < .001). In multivariate logistic regression analysis, MHR was an independent predictor of high thrombus burden (odds ratio: 1.067, 95% CI: 1.031-1.105; P < .001). The area under the receiver–operating characteristic curve of the MHR was 0.688 (0.641-0.733; P < .001) to predict high thrombus burden. In conclusion, MHR was independent predictor of high thrombus burden in patients with STEMI who underwent primary PCI.

Abstract
AIM Recently, monocyte-to-high density lipoprotein ratio (MHR) has been proposed as a novel prognostic indicator of cardiovascular diseases. However, no study is currently available regarding the comparison between MHR and monocyte count (MC) in predicting the outcomes among patients undergoing coronary angiography. METHODS A total of 3798 patients scheduled for selective coronary angiography were enrolled and followed up to capture major adverse cardiovascular events (MACEs, death, acute myocardial infarction, unstable angina, stroke, heart failure, and unexpected coronary revascularization). Cox proportional hazards models were used to evaluate the risk of MHR or MC on MACEs. RESULTS During a median of 24.6 months follow-up, 347 (9.1%) MACEs occurred. The upper tertiles of MC and MHR have a significant lower event-free survival (p = 0.011; p = 0.014, respectively). Significantly, both MC and MHR were associated with increased MACEs risk after adjusting for potential confounders [adjusted HR (95% CI): 2.734 (1.547-4.832); 2.031 (1.268-3.254), respectively]. Additionally, the area under the receiver-operating characteristic curves of MC or MHR in predicting MACEs were 0.574 (0.542-0.606) and 0.562 (0.530-0.594) (p < 0.001, both), respectively. CONCLUSIONS Our data firstly indicated that MHR was an independent predictor of MACEs whereas the prognostic impact was not superior to MC in patients who underwent coronary angiography. Key Messages MHR has been suggested as a novel prognostic indicator of several cardiovascular diseases. No study is currently available regarding the comparison of MHR to MC in predicting the outcomes in a large cohort of patients undergoing coronary angiography. Our data firstly indicate that MHR is independently associated with MACEs in patients undergoing coronary angiography whereas the prognostic impact is similar to MC.

Abstract
AIM This study aims to assess the predictive role of the preprocedural circulating monocyte to high-density lipoprotein (HDL) cholesterol ratio (MHR) on the occurrence of stent restenosis (SR) in patients with stable and unstable angina pectoris undergoing successful bare-metal stenting (BMS). PATIENTS & METHODS Between February 2008 and June 2014, a total of 831 patients with stable and unstable angina pectoris who underwent successful BMS were retrospectively analyzed. Demographic and clinical characteristics of the patients were recorded. Left ventricular ejection fraction and laboratory data were also noted. RESULTS In the receiver operating characteristics curve analysis, MHR >14 had 71% sensitivity and 69% specificity in predicting SR. CONCLUSION Our study results show that preprocedural MHR is an independent predictor of SR in this patient population.

Abstract
AIM We aimed to investigate whether baseline monocyte to high-density lipoprotein cholesterol ratio (MHR), an easily available inflammatory and oxidative stress marker, is associated with SYNTAX score. PATIENTS & METHODS In this cross-sectional study, n = 1229 consecutive patients with coronary artery disease were classified into two groups, low SYNTAX score (≤22) and high SYNTAX score (≥23). RESULTS MHRs were significantly higher in patients with high SYNTAX score (p < 0.05). In multivariate regression analysis, MHR remained as independent predictor of high SYNTAX score together with C-reactive protein (CRP), hypertension and diabetes mellitus. In correlation analysis, MHR showed significant positive correlations with SYNTAX score (r = 0.371, p < 0.001) and CRP level (r = 0.336, p < 0.001). CONCLUSION This study suggests MHR is independently associated with burden of coronary atherosclerosis.

Abstract
In a study of 14 patients (11 Japanese and 3 white North Americans) with aldosterone-producing tumor carried out within 2 to 4 weeks after unilateral adrenalectomy, both plasma renin activity (PRA) and plasma aldosterone concentration (PAC) increased almost normally with short-term sodium depletion and upright posture. Aldosterone excretion rate (AER) also increased significantly with sodium depletion, and was normally suppressed by sodium loading. Highly significant correlations were observed between PRA and PAC (r=0.89, p < 0.001) or AER (r=0.88, p < 0.001) ater operation, whereas there had been no such correlation before operation. Either physiological or laboratory findings were normalized or markedly improved in all cases although pathohistological diagnosis was made as adenomatous hyperplasia in 10 out of 11. These results indicate that within 4 weeks of operation PRA and the remaining adrenal gland can almost normally respond to stimuli such as sodium depletion and upright posture regardless of the amount of spironolactone given preoperatively.
