Objective: Monocyte to high-density lipoprotein ratio is considered as a new inflammatory marker and has been used to predict the severity of coronary heart disease and the incidence of adverse cardiovascular events (ACEs). However, there is a lack of data relative to large artery atherosclerosis (LAA) ischemic stroke. We investigated whether the monocyte to high-density lipoprotein (HDL) ratio (MHR) is related to the 3-month functional prognosis of LAA ischemic stroke.Materials and Methods: A retrospective analysis was conducted on 316 LAA ischemic stroke patients. The 3-month functional outcome was divided into good and poor according to the modified Rankin Scale (mRS) score. Multivariate logistic regression analysis was performed to evaluate the correlation between MHR and prognosis of ischemic stroke.Results: The MHR level of poor functional outcome group was higher than that of the good functional outcome group [0.44 (0.3, 0.55) vs. 0.38 (0.27, 0.5), P = 0.025]. Logistic stepwise multiple regression revealed that MHR [odds ratio (OR) 9.464, 95%CI 2.257–39.678, P = 0.002] was an independent risk factor for the 3-month poor outcome of LAA ischemic stroke. Compared to the lower MHR tertile, the upper MHR tertile had a 3.03-fold increase (95% CI 1.475–6.225, P = 0.003) in the odds of poor functional outcome after adjustment for potential confounders. Moreover, a multivariable-adjusted restricted cubic spline (RCS) showed a positive close to a linear pattern of this association.Conclusion: Elevated MHR was independently associated with an increased risk of poor 3-month functional outcome of patients with LAA ischemic stroke.

Objectives. High levels of non high density lipoprotein cholesterol (non-HDL-C) are known to contribute to an increased risk of ischemic stroke. This systematic review was conducted to identify the relationship between high non-HDL-C levels and the risk of ischemic stroke. Material and methods. This systematic review using PRISMA (preferred reporting items for systematic reviews and meta-analyses) statement guideline, with a pre-determined search strategy. The search was conducted in Pubmed Central (PMC) and Pubmed from 2009 until 2020 with inclusion criteria, patients with a diagnosis of ischemic stroke, age >18 years, with non-HDL-C levels. The title and abstract of these articles were reviewed for relevance, based on inclusion criteria. This systematic review using STROBE to evaluate the quality in individual study which consists of 22 domains. Results. In the final stage, this systematic review identifies six cohort study consisting 166.720 participants. Overall, the quality in individual studies based on STROBE is good. We reported that there are two studies report that high non-HDL-C levels can significantly increase the risk of ischemic stroke. Meanwhile, there are four studies that report there was no significant relationship between high non-HDL-C levels and the risk of ischemic stroke. Conclusions. Overall, this systematic review provides the result about relationship between high levels of nonHDL-C and the risk of ischemic stroke, there are two studies with a larger population support that high levels of non-HDL-C can increase the risk of ischemic stroke. However, further studies is needed with a large population that specifically identify the relationship between non-HDL-C levels and risk of ischemic stroke and makes a better adjustments for confounding variables.

Objectives: Stroke is recognized to be the third most common cause of mortality, with increasing incidence among developing countries. Recognition and control of risk factors is of prime importance in the prevention of stroke. We aimed to study the characteristics of ischemic stroke (IS) patients in Oman, and quantify its various risk factors using a case-control model. Methods: This study conducted from January 2012 to March 2013 included 255 adult Omani patients with IS admitted to two premier hospitals in Oman, compared to 255 age- and gender-matched controls. Demographic factors and frequency of various conventional risk factors were documented. Univariate and step-wise multivariate logistic regression analysis were performed to evaluate the risk factors associated for IS. Results: Of the 255 cases, 63% were males. The mean age was 62.2 ± 13.2 years. Most of the cases (89%)  were above 45 years of age. Cardio-embolism(32%) was the commonest mechanism of IS. The stepwise multiple logistic regression model revealed that family history of stroke was the strongest independent risk factor with odds ratio (OR) of 10.10, followed by hypertension with OR of 5.17 and high-density lipoprotein with OR 3.34 (p< 0.01). Conclusions: Cardio-embolism was the predominant mechanism of IS in this study. Family history of stroke, hypertension and reduced high-density lipoprotein were the leading independent risk factors. Strong emphasis on screening for risk factors, control of hypertension and life-style modification for those with family history of stroke, would be expected to emerge as the major stroke-preventive measures in Oman.

Introduction: With an aging population, an increased number of acute stroke patients with pre-stroke dementia is expected. Although both stroke and dementia are major cause of disability, the effect of pre-stroke dementia on functional outcome after stroke has been still on debate. Hypothesis: Pre-stroke dementia is associated with poor functional outcome after acute ischemic stroke. Methods: Of 9198 stroke patients registered in the Fukuoka Stroke Registry in Japan from June 2007 to May 2014, 3843 patients with first-ever ischemic stroke within 24h of onset, who had been functionally independent before the onset, were enrolled in this study (cardioembolism [n=926], large artery atherosclerosis [n=583], small vessel occlusion [n=1045], others [n=1289]). Pre-stroke dementia was defined as any type of dementia that was present prior to the stroke. For propensity score (PS)-matched analysis, 320 pairs of patients with and without pre-stroke dementia were also selected. Study outcome was poor functional outcome (modified Rankin Scale 3-6) at discharge. Results: In the total cohort, 330 (8.6%) had pre-stroke dementia. The age (80±8 vs 69±13, year, mean±SD, p<0.01), frequencies of female (46 vs 36, %, p<0.01) and cardioembolism (41 vs 23, %, p<0.01), and NIHSS score on admission (6 [3 - 12] vs 3 [1 - 6], median [interquartile], p<0.01) were higher in patients with pre-stroke dementia than those without the dementia. Poor functional outcome (62 vs 25, %, p<0.01) were more prevalent in patients with pre-stroke dementia than those without the dementia. Multivariable-adjusted analysis showed that pre-stroke dementia was significantly associated with increased risk for poor functional outcome (OR 2.3, 95% CI 1.7-3.2). There were no interactions between pre-stroke dementia and 4 variables (age, sex, stroke subtype, and initial stroke severity [NIHSS≤7 or NIHSS≥8]). In the PS-matched analysis, pre-stroke dementia was still associated with poor functional outcome (OR 4.3, 95%CI 2.1-8.8). Conclusions: Pre-stroke dementia was significantly associated with poor functional outcome at discharge in patients with acute ischemic stroke.

Abstract: The inverse relationship between low plasma high-density lipoprotein cholesterol (HDL-C) concentrations and increased risk of Atherosclerotic Cardiovascular Disease (ASCVD) is well-known. However, plasma HDL-C concentrations are highly variable in subjects with ASCVD. In clinical outcome trials, pharmacotherapies that increase HDL-C concentrations are not associated with a reduction in ASCVD events. A causal relationship between HDL-C and ASCVD has also been questioned by Mendelian randomization studies and genome-wide association studies of genetic variants associated with plasma HDL-C concentrations. The U-shaped association between plasma HDL-C concentrations and mortality observed in several epidemiological studies implicates both low and very high plasma HDL-C concentrations in the etiology of ASCVD and non-ASCVD mortality. These data do not collectively support a causal association between HDL-C and ASCVD risk. Therefore, the hypothesis concerning the association between HDL and ASCVD has shifted from focus on plasma concentrations to the concept of functionality, in particular cellular cholesterol efflux and HDL holoparticle transport. In this review, we focus on these new concepts and provide a new framework for understanding and testing the role of HDL in ASCVD.

Background. The purpose of this study was to evaluate the association between the non-high-density lipoprotein cholesterol (non-HDL-C) to high-density lipoprotein cholesterol (HDL-C) ratio and the risk of coronary artery disease (CAD). We also explored the potential role of non-HDL-C/HDL-C in the prognosis of CAD. Methods. We analyzed 930 consecutive patients with chest discomfort who underwent coronary angiography. Of these, 680 were diagnosed with CAD; the remaining 250 patients were normal. Multivariate logistic regression and receiver operating characteristic (ROC) curves were employed to evaluate the association between non-HDL-C/HDL-C and CAD. The effect of non-HDL-C/HDL-C on the progression of major adverse cardiovascular events (MACEs) was also explored. Results. Increased non-HDL-C/HDL-C was associated with an increased risk of CAD (OR: 1.291; 95% CI: 1.039-1.561; P=0.013). The results of stratified analyses by CAD subtype showed a correlation between high non-HDL-C/HDL-C and increased risk of acute coronary syndrome (OR: 1.661; 95% CI: 1.259-2.207; P<0.001), high Gensini score (OR: 1.408; 95% CI: 1.021-1.935; P=0.039), and multivessel disease (OR: 1.487; 95% CI: 1.128-1.992; P=0.007). Moreover, the areas under the ROC for the predictive value of non-HDL-C/HDL-C for CAD, acute coronary syndrome, high Gensini score, and multivessel disease were 0.604, 0.658, 0.642, and 0.636, respectively. Non-HDL-C/HDL-C in CAD patients was significantly correlated with the risk of long-term MACEs (P=0.004). Conclusions. The findings of this study indicated that non-HDL-C/HDL-C plays an important role in the risk and progression of CAD. These findings need verification by further large-scale prospective studies.

Objective.Ankylosing spondylitis (AS) is a chronic inflammatory disease associated with increased risk of cardiovascular disease (CVD). High-density lipoprotein (HDL) exerts a series of antiatherogenic properties and protects from CVD. We evaluated whether HDL antiatherogenic properties are impaired in patients with AS.Methods.HDL (apoB-depleted serum) was isolated from 35 patients with AS and 35 age- and sex-matched controls. We measured the antioxidant capacity of HDL, the ability of HDL to induce cholesterol efflux, the activity of HDL-associated enzymes paraoxonase-1 (PON1) and myeloperoxidase (MPO), as well as the ability of HDL to induce Akt kinase activation.Results.HDL from patients with AS had decreased antioxidant capacity and decreased ability to promote cholesterol efflux from macrophages compared to controls. HDL-associated PON1 activity was lower and HDL-associated MPO activity higher in patients with AS compared to controls. Higher MPO activity correlated positively with lower antioxidant capacity of HDL in patients with AS. In addition, HDL from patients with AS had impaired endothelial Akt kinase activating properties that were inversely correlated with the MPO/PON1 ratio and positively correlated with the cholesterol efflux capacity of HDL.Conclusion.HDL from patients with AS displays impaired antiatherogenic properties. Attenuation of HDL properties may constitute a link between AS and CVD.
