Objective: Lipids play key role in coronary atherosclerosis. The role of non-high-density lipoprotein cholesterol (non-HDL-C) in atherosclerotic plaques using intravascular imaging remains unclear. This study aimed to assess its relationship with coronary plaque features using intravascular ultrasound (IVUS) in acute coronary syndrome (ACS). Methods: A total of 601 patients divided into two groups: normal non-HDL-C≤130 mg/dl (n = 410) and high non-HDL cholesterol >130 mg/dl (n = 191). IVUS performed before coronary intervention. Results: Mean age 53.18 ± 12.29 years. No significant differences in hypertension, diabetes, and smoking between groups. Plaque burden was significantly higher among normal versus high non-HDL-C groups (79.59 ± 9.98 % vs. 81.61 ± 5.39 %; p = 0.001). At minimal luminal site, fibrofatty percentage was higher in normal non-HDL-C group (p = 0.027), while necrotic core greater in high non-HDL-C group (p = 0.033). Segmental analysis, necrotic core was significantly higher in percentage (p = 0.006) and volumes (p = 0.011) in normal versus high non-HDL-C groups. Total cholesterol (r = 0.099, p = 0.015), LDL-C (r = 0.081, p = 0.046), triglycerides (r = 0.083, p = 0.041),and non-HDL-C (r = 0.099, p = 0.015) positively correlated with plaque burden. Total cholesterol (r = 0.115, p = 0.005), LDL-C (r = 0.107, p = 0.009), and non-HDL-C (r = 0.105, p = 0.010) positively correlated with necrotic core volume. Linear regression analysis showed age and non-HDL-C as predictors of higher plaque burden. Multiple linear regression analysis; age, body mass index, and non-HDL-C were predictors of larger necrotic core volume. Conclusion: Non-HDL-C levels were positively associated with plaque burden, measure of extent of atherosclerosis. It is closely associated with and is a predictor of necrotic core volume; a marker of plaque vulnerability. This IVUS study demonstrates potential role of non-HDL-C in causation of plaque in ACS.

Background: Non-alcoholic fatty liver disease (NAFLD) has become the predominant chronic liver disease globally in recent years, mostly due to the rise in obesity and metabolic syndrome (MS). Non-high-density lipoprotein cholesterol (non-HDL-c) and the ratio of non-HDL-c to HDL-c are emerging as significant indicators for cardiovascular disease risk, especially in patients with metabolic disorders. Method: This observational and record-based study focuses on lipid profile estimations using routine fasting samples billed during March 2022. All samples processed on the Vitros 5.1 FS for lipid profile between March 1st and March 31st, 2022, were included. The study variables were fasting total cholesterol (TC), fasting HDL, fasting LDL, and fasting triglycerides (TG). Inclusion criteria included all samples assayed, while exclusion criteria excluded hemolyzed samples and non-fasting samples. Blood samples, approximately 3ml, were collected after an overnight fasting period of 8-12 hours. Lipid profile estimations were conducted using the Vitros 5.1 FS, employing dry chemistry methods. Result: Descriptive statistics showed that the mean total cholesterol (TC) was 196.68 mg/dL, HDL was 43.16 mg/dL, and non-HDL was 153.52 mg/dL. The CHOL/HDL ratio had a mean of 4.77. A strong positive correlation (r = 0.815, p = 0.001) was observed between non-HDL cholesterol and the CHOL/HDL ratio. Conclusion: The study concludes that lipid profiles should include both non-HDL cholesterol and the cholesterol to HDL ratio. These parameters, when considered alone and in combination, provide a more accurate marker for predicting cardiovascular risk and are highly associated. [ABSTRACT FROM AUTHOR]

Background Childhood cancer survivors have increased risk of dyslipidemia and atherosclerotic cardiovascular disease (CVD). The aim of this study was to evaluate the prevalence and associated cardiovascular risks of specific lipid abnormalities among childhood cancer survivors. Methods Comprehensive lipid panel measurements were obtained from 4115 5-year survivors, with 3406 (mean age at evaluation = 35.2 years, SD = 10.4 years) not having previous dyslipidemia diagnosis, as well as 624 age, sex, and race and ethnicity matched community controls. Results Previously undiagnosed dyslipidemia with abnormal low-density lipoprotein (LDL) cholesterol (>160 mg/dL), non–high density lipoprotein (HDL) cholesterol (>190 mg/dL), HDL cholesterol (<40 mg/dL for men, <50 mg/dL for women), and triglycerides (>150 mg/dL) were identified in 4%, 6%, 30%, and 17%, respectively. Survivors without previous dyslipidemia diagnosis had higher LDL cholesterol and non-HDL cholesterol and lower HDL cholesterol than community controls. Cranial radiotherapy (relative risk [RR] = 2.2, 95% confidence interval [CI] = 1.6 to 3.0 for non-HDL cholesterol) and total body irradiation for hematopoietic cell transplantation (RR = 6.7, 95% CI = 3.5 to 13.0 for non-HDL cholesterol; RR = 9.9, 95% CI = 6.0 to 16.3 for triglycerides) were associated with greater risk of dyslipidemia. Diagnoses of low HDL cholesterol (hazard ratio [HR] = 2.9, 95% CI = 1.8 to 4.7) and elevated triglycerides (HR = 3.1, 95% CI = 1.9 to 5.1) were associated with increased risk for myocardial infarction, and diagnoses of high LDL cholesterol (HR = 2.2, 95% CI = 1.3 to 3.7), high non-HDL cholesterol (HR = 2.2, 95% CI = 1.3 to 3.7), low HDL cholesterol (HR = 3.9, 95% CI = 2.8 to 5.4), and elevated triglycerides (HR = 3.8, 95% CI = 2.7 to 5.5) were associated with increased risk for cardiomyopathy. Conclusions Previously undiagnosed dyslipidemia among childhood cancer survivors was associated with increased risk for myocardial infarction and cardiomyopathy. Comprehensive dyslipidemia evaluation and treatment are needed to reduce cardiovascular morbidity in this population. [ABSTRACT FROM AUTHOR]

Aim. To evaluate the associations of abdominal obesity (AO), adipokines and premature coronary artery disease (CAD) in young people for a deeper understanding of the pathogenesis of atherosclerotic diseases.Material and methods. A total of 1457 people were examined, including 653 (44,8%) men. Mean age was 36,7±6,0 years. Premature CAD was detected in 46 people, while 4 following subgroups were formed (138 people in total): with CAD and AO; with CAD, without AO; control groups by age and sex: without CAD, with AO; without CAD, without AO.Results. Premature CAD in young people is associated with an increase in non-high-density lipoprotein cholesterol (non-HDL-C). Univariate analysis found that the probability of CAD increased by 1% with an increase in adiponectin level, and by 0,2% with an increase of 1 ng/ml in resistin level. Multivariate regression analysis, including sex, age, waist circumference, non-HD-C, adiponectin, and resistin, significant associations were obtained for non-HDL-C and adiponectin. With AO, the CAD probability increased by 0,6% with an increase in plasminogen activator inhibitor-1 level (PAI-1). However, when non-HDL-C was included in the model, significance for this biomarker was not achieved.Conclusion. In young people, CAD is associated with increased levels of non-HDL cholesterol, adiponectin, resistin and PAI-1. Independent associations with premature CAD were obtained only for adiponectin, which makes this marker promising for study in young people.

IntroductionTriglyceride-rich remnant lipoproteins (TRLs) are considered atherogenic due to the presence of remnant cholesterol, which is transported by apolipoprotein B. In clinical practice, the concentration of TRLs can be estimated by calculating remnant cholesterol or non-HDL cholesterol levels.AimThis study aims to investigate the proportion of patients who have low LDL cholesterol (LDL-C) concentration but elevated remnant cholesterol concentration, stratified by the presence of hypertriglyceridaemia and ethnicity, using real-world hospital data. Our secondary aim is to investigate the proportion of patients with elevated non-HDL cholesterol levels using guideline-recommended goals.MethodsA 2-year retrospective study was conducted at a single centre, analyzing lipid blood tests of all patients, including directly measured LDL-C. Fasting for blood tests was not mandatory.ResultsThe study included a total of 21,605 consecutive patients with plasma lipid profiles analyzed in our hospital laboratory. The median age was 61 years. In patients with ASCVD (n = 14,704), 23.7% had an LDL-C level of 0.65 mmol/L was present in 11% of all patients. The current guideline-recommended non-HDL-C goal, which uses a 0.8 mmol/L estimate of remnant cholesterol concentration, was achieved in >92% of patients, suggesting that it is unlikely to be clinically useful for the majority of our patient population except where there is concomitant hypertriglyceridaemia. Further studies are needed to establish the appropriate non-HDL-C goal or calculated remnant cholesterol concentration, paired with the LDL-C goal or otherwise, in a Southeast Asian population.

Background: Growing evidence shows the undisputable role of non-HDL-C and remnant cholesterol (remnant-C) in cardiovascular disease (CVD) risk assessment and treatment. However, the reference interval (RI) for these lipid parameters is not readily available. The aim of the present investigation was to determine the age and sex-specific RIs for non-HDL-C and remnant-C as well as other lipid parameters among a healthy population in southern Iran. We also report the RI of lipid parameters in rural and urban residents, smokers and post-menopausal women. Methods: Among 14 063 participants of Bandare Kong and Fasa cohort studies, 792 healthy subjects (205 men and 578 women) aged 35-70 years were selected. Fasting blood samples were used for determination of total cholesterol (TC), triglycerides (TG) and HDL-C using colorimetric methods. Non-HDL-C and remnant-C were calculated using the valid formula. The 2.5th and 97.5th percentiles were calculated and considered as RI. Results: In the total population (n = 792, age 35-70), RIs for non-HDL-C and remnant-C was 74.0-206.8 and 8.0-52.7 mg/dL, respectively. Age (35-44 and ≥ 45 years) and gender-specific RIs for serum non-HDL-C and remnant-C were determined. Remnant-C and non-HDL-C level were different between sex and age categories. The mean value of all lipid parameters except HDL-C was higher in men, urban residents, subject with age ≥ 45 years and smokers. Conclusion: This is the first study in which the RIs for non-HDL-C and remnant-C in southern Iran are reported. This may help physicians to conveniently use these lipid parameters for patient care and better cardiovascular risk assessment. [ABSTRACT FROM AUTHOR]

Triglycerides are associated with cardiovascular risk largely mediated by their final product of catabolism, the cholesterol-rich remnant, which may come from the liver or the intestine. There is a direct association between fasting and postprandial triglycerides and cardiovascular risk. ApoB is associated with the number of particles and the amount of RC, which explains its determining role in CVD. Non-HDL cholesterol represents atherogenic lipoproteins, with correlation and concordance with apoB; both are cardiovascular risk markers. Lipoprotein (a) is a cardiovascular risk factor not only because of the cholesterol and apoB it contributes, but also because of its proinflammatory and prothrombotic activity. Viewing these factors holistically, it is important to note that it is primarily a reduction in apoB, remnant cholesterol and non-HDL cholesterol that reduces cardiovascular events. A 10% weight loss improves TG levels without reducing apoB or cardiovascular risk. Of the classic lipid-lowering agents, high-dose statins and ethyl eicosapentanoate reduce cardiovascular risk through apoB, RC, and non-HDL reduction. To date, we do not have lipid-lowering agents aimed at reducing Lp(a), which is only slightly reduced by PCSK9 inhibitors and markedly reduced by LDL apheresis. These residual risk markers serve not only to stratify cardiovascular risk but also to establish follow-up goals. [ABSTRACT FROM AUTHOR]

This study was designed to determine the association between non-HDL-C in patients with prior coronary artery bypass graft (CABG) with ACS and clinical outcomes.Methods: We retrospectively analyzed 468 patients with prior CABG with ACS and categorized them into two groups based on the median non-HDL-C level. The primary endpoints were major adverse cardiovascular events (MACEs), including cardiovascular death and recurrent myocardial infarction. Kaplan–Meier curves, Cox proportional-hazard regressions, and restricted cubic splines were used to determine the association between non-HDL-C and MACEs. The discrimination and reclassification of the nomogram based on non-HDL-C were assessed using time-dependent receiver operating characteristic (ROC) curves and net reclassification improvement (NRI).Results: During the average follow-up time of 744.5 days, non-HDL-C was independently associated with the occurrence of MACEs (hazard ratio [HR] = 5.01, 95% confidence interval [CI] = 1.65– 15.24; p = 0.005) after adjusting for other lipid parameters. The spline curves indicated a linear relationship between non-HDL-C and MACEs (p-nonlinear: 0.863). The time-dependent areas under the ROC curves of prior-CABG-ACS nomograms containing non-HDL regarding MACEs in two consecutive years were 91.7 (95% CI: 85.5– 97.9) and 91.5 (95% CI: 87.3– 95.7), respectively. The NRI analysis indicated that the prior-CABG-ACS model improved the reclassification ability for 1- and 2-year MACEs (22.4% and 7%, p < 0.05, respectively).Discussion: Non-HDL is independently associated with the risk of MACEs in patients with prior CABG with ACS. The prior-CABG-ACS nomogram based on non-HDL-C and five convenient variables generates valid and stable predictions of MACE occurrence.Keywords: non-HDL cholesterol, major adverse cardiovascular events, prior coronary artery bypass grafting, GRACE score

Papers on the familial lipid disorder, dysbetalipoproteinemia (FD), appeared in early seventies of the last century describing the combined elevation in total cholesterol (TC) and triglycerides (TG) in the blood of affected individuals, which is associated with mutations in the apo-lipoprotein E (Apo E) gene. Different methods and measurements for diagnosis and consequent treatment of these cases had been suggested. Stress was put on the E2/E2 homozygotes, Apo B and non-high density lipoprotein cholesterol as the main obvious manifestations of the disease, with a big variation in the results among different workers. This short review will present most of these variations in nature, diagnosis and management of FD, with a reference to a recent Iraqi work on this subject. [ABSTRACT FROM AUTHOR]

Background & aims: Premature coronary artery disease (CAD) is endemic in India. We performed a study to identify risk factors, clinical presentation, angiographic findings and interventions in premature CAD. Methods: Successive patients who underwent percutaneous intervention (PCI) were enrolled from January 2018 to June 2021. Premature CAD was defined as women 45-59 y and men 40-54 y and very premature as women

Background Previous results provide supportive but not conclusive evidence for the use of omega‐3 fatty acids to reduce blood lipids and prevent events of atherosclerotic cardiovascular disease, but the strength and shape of dose–response relationships remain elusive. Methods and Results This study included 90 randomized controlled trials, reported an overall sample size of 72 598 participants, and examined the association between omega‐3 fatty acid (docosahexaenoic acid, eicosapentaenoic acid, or both) intake and blood lipid changes. Random‐effects 1‐stage cubic spline regression models were used to study the mean dose–response association between daily omega‐3 fatty acid intake and changes in blood lipids. Nonlinear associations were found in general and in most subgroups, depicted as J‐shaped dose–response curves for low‐/high‐density lipoprotein cholesterol. However, we found evidence of an approximately linear dose–response relationship for triglyceride and non‐high‐density lipoprotein cholesterol among the general population and more evidently in populations with hyperlipidemia and overweight/obesity who were given medium to high doses (>2 g/d). Conclusions This dose–response meta‐analysis demonstrates that combined intake of omega‐3 fatty acids near linearly lowers triglyceride and non‐high‐density lipoprotein cholesterol. Triglyceride‐lowering effects might provide supportive evidence for omega‐3 fatty acid intake to prevent cardiovascular events.

BackgroundThe relationship between cumulative non-high-density lipoprotein cholesterol (non-HDL-C) burden and atherosclerotic cardiovascular disease (ASCVD) remains unclearObjectiveTo prospectively examine the association between cumulative non-HDL-C burden and ASCVD risk in the Kailuan cohort of China.MethodsA total of 49,679 subjects who were free of ASCVD participated in three consecutive examinations in 2006, 2008 and 2010 were enrolled. Duration and concentration of cumulative exposure to non-HDL-C (cumNon-HDL-C) were respectively used to estimate the extent of cumulative non-HDL-C burden. The participants were divided into four groups according to durations of cumNon-HDL-C (0, 2, 4 and 6 years) and five groups according to the quintiles of cumNon-HDL-C concentration (

Background: Recent research has demonstrated the possible relevance of bilirubin in metabolic and cardiovascular disorders. Lipid abnormalities are a major problem that is related with an increased risk of cardiovascular disease in diabetics. This study examined the relationship between serum bilirubin and direct bilirubin concentrations and atherogenic lipids in patients with type 2 diabetes (T2DM). Methods: This cross-sectional included 67 patients with type 2 diabetes and 39 matched healthy control. The lipid profile, including total cholesterol, HDL-C, and TG levels, fasting blood glucose, total bilirubin, direct bilirubin, ALT, AST, and ALP were measured using a dimension EXL clinical chemistry analyzer (Siemens Healthcare Diagnostics). Cholesterol in VLDL, LDL, and sdLDL were calculated from standard lipid assay results by the equations of Sampson et al. Results: Serum bilirubin was lower in non T2DM subjects nearly significant (p=0.0.51) whereas direct bilirubin concentrations were lower in T2DM (p=0.008). ALT, AST, and ALP levels were higher in T2DM groups. The mean values of LDL-C, sdLDL-C, non HDL-C and VLDL-C were significantly increased in T2DM group and lower HDL-C. An inverse relationship could be observed with increase in serum total bilirubin and serum levels of LDL-C (r2=0.139, p<0.005), sdLDL-C (r2=0.137, p<0.005), VLDL-C (r2=0.074, p<0.044), and non HDL-C (r2=0.166, p<0.002) in T2DM group. The same inverse relationship was observed with serum direct bilirubin and serum levels of LDL-C (r2=0.133, p<0.006), sdLDL-C (r2=0.172, p<0.001), VLDL-C (r2=0.118, p<0.01), and non HDL-C (r2=0.182, p<0.001) in T2DM group. Conclusions: A significant negative association was found between serum bilirubin levels and direct serum bilirubin with atherogenic lipids, suggesting that serum bilirubin may protect T2DM patients from development of cardiovascular disease. These findings indicate the need for additional research in a large cohort. [ABSTRACT FROM AUTHOR]

Background/Aims: Statin intolerance leads to poor adherence to statin therapy, resulting in a failure to achieve desired cholesterol reduction and adverse outcomes. The LILRB5 Asp247Gly genotype has been identified as being associated with statin intolerance and statin-induced myalgia. We conducted a randomized clinical trial to examine its role in immune response through T regulatory cell aggregation and in achieving cholesterol reduction targets. Methods: A double-blind, cross-over, recruit-by-genotype trial was undertaken. A total of 18 participants who had either the Asp247Asp (T/T) genotype or the Gly247Gly (C/C) genotype were recruited to the study. Participants were randomised to receive placebo or atorvastatin 80 mg daily for 28 days. Following a washout period of 3 weeks, they were then switched to the opposite treatment. Biochemical and immunological measurements as well as interviews were performed prior to and after both treatment periods. Within genotype group comparisons were performed using repeated measures Wilcoxon tests. Two-way repeated measures ANOVA with genotype and treatment as factors were used to compare changes in biochemical parameters between groups during placebo and atorvastatin periods. Results: Individuals with the Asp247Asp genotype had a greater increase in creatine kinase (CK) compared to those with Gly247Gly genotype in response to atorvastatin (p = 0.03). Those with Gly247Gly genotype had a mean non-HDL cholesterol reduction of 2.44 (95% CI:1.59 - 3.29) mmol/L while in Asp247Asp genotype group the mean reduction was 1.28 (95%CI: 0.48 - 2.07) mmol/L. The interaction between the genotype and atorvastatin treatment for total cholesterol (p = 0.007) and non-HDL cholesterol response was significant (p = 0.025). Immunological assessment showed no significant changes in aggregation of T regulatory cells by genotype. Conclusion: The Asp247Gly variant in LILRB5, previously associated with statin intolerance, was associated with differential increases in creatine kinase and total cholesterol and non-HDL cholesterol-lowering response to atorvastatin. Taken together, these results suggest that this variant could have utility in precision cardiovascular therapy. [ABSTRACT FROM AUTHOR]

Context The relative importance of the control of different metabolic risk factors for the prevention of chronic kidney disease among patients with diabetes in real life conditions is insufficiently understood. Objective We evaluated the effect of the achievement of glycated hemoglobin A1c (HbA1c), systolic blood pressure (SBP), and low-density lipoprotein cholesterol (LDLc) or non–high-density lipoprotein cholesterol (non-HDLc) goals (ABC goals) on the development of incident chronic kidney disease (iCKD) among patients with diabetes. Methods In a nationwide registry of all individuals diagnosed with diabetes assisted by the health system in Colombia, we analyzed the association between baseline or sustained goal achievement and development of iCKD over a 4-year follow-up. iCKD was defined as a new occurrence of an estimated glomerular filtration rate less than 60 mL/min/1.73 m2, hemodialysis, peritoneal dialysis, or kidney transplant. Results The study included 998 790 adults with diabetes (56% female, mean age 59). There were 125 626 cases of iCKD. After adjustment for multiple confounders, a baseline SBP less than 130 mm Hg (odds ratio [OR] 0.79 [0.78-0.80]) and a baseline HbA1c less than 7.0% (OR 0.86 [0.85-0.87]) were negatively associated with iCKD. Sustained achievement showed stronger negative associations with iCKD than just baseline achievement. Considering each goal separately, sustained non-HDLc less than 130 mg/dL had the strongest negative association with iCKD (OR 0.67 [0.65-0.69]). Patients who maintained the triple ABC goal over the entire follow-up had 32% (29-34) lower odds of developing CKD, 38% (34-42) if they additionally kept a normal body mass index (BMI). Sustained ABC control including a normal BMI was more strongly associated with a lower incidence of CKD in patients of Black race (OR 0.72 vs 0.89; P for interaction = .002). Conclusion At the country level, sustained achievement of ABC goals and most especially non-HDLc were associated with substantial reductions in iCKD. [ABSTRACT FROM AUTHOR]

In this multi-dose phase-2 study, we evaluated the safety and efficacy of TRC150094 in diabetic subjects with dyslipidemia receiving standard of care.Methods: A randomized, multicenter, double-blind, placebo-controlled, parallel-group, Phase 2 study was conducted in 225 subjects from July 2013 to August 2015. The key inclusion criteria were body mass index of 23– 35 kg/m2, age between 30 and 65 years, fasting glucose of ≥ 126 or glycated hemoglobin (HbA1c) of ≥ 6.4% stabilized on treatment with ≤ 2 oral hypoglycemic agents, apolipoprotein-B (apo-B) ≥ 100 mg/dL, serum triglyceride (TG) ≥ 150 mg/dL, systolic blood pressure (SBP) ≥ 130 mmHg, and diastolic blood pressure (DBP) ≥ 85 mmHg with/without antihypertensive treatment. The subjects were randomly assigned to one of three TRC150094 doses (25, 50, or 75 mg) or placebo for 24 weeks. The outcomes assessed included fasting plasma glucose (FPG), insulin, mean arterial blood pressure (MAP), and apoB. In addition, safety and tolerability were assessed.Results: A reduction for dose up to 50 mg was noted for FPG in the range of 13.9 to 21.7 mg/dL (p < 0.05 for TRC150094 25 and 50 mg), fasting insulin reduction in the range 2.7 to 6.0 mU/L (all doses, p > 0.05), and improved HOMA-IR (− 2.0 to − 2.5) (all doses, p > 0.05) compared to placebo after 24 weeks of treatment. Furthermore, a significant reduction in MAP in the range 3.1 to 4.2 mmHg (p < 0.05 for TRC150094 25 and 75 mg) was noted. In addition, TRC150094 treatment was weight neutral, had a favorable effect on lowering atherogenic lipid fractions, including non-HDL cholesterol (− 6.8 mg/dL at 50 mg dose). Adverse events were mild to moderate in nature and not dose-related. One adverse event not related to treatment led to the discontinuation of the study. Overall, TRC150094 was safe and well tolerated for up to 24 weeks.Conclusion: In this study, TRC150094 treatment in the dose range of 25 to 50 mg showed improvement in various components of CMBCD, ie, dysglycemia, dyslipidemia, and hypertension.Trial Registration: This study was registered in the Clinical Trial Registry of India. Trial registration number: CTRI/2013/03/003444.

Background: The atherogenic potential of remnant cholesterol, which refers to the cholesterol content of triglyceride-rich, non-low-density lipoprotein (LDL) particles in circulation, has gained increasing attention recently. Unfortunately, very limited information is available regarding remnant cholesterol levels in Indian subjects., Methods: This was a retrospective study conducted at a premier, tertiary care center in North India. A total of 3064 consecutive subjects [mean age 61.3 ± 10.3 years, 2550 (83.2%) men] with newly diagnosed coronary artery disease (CAD) undergoing coronary revascularization were included. Enzymatic assays were used for measuring various lipid parameters. Remnant cholesterol was calculated by subtracting LDL cholesterol (LDL-C) and high-density lipoprotein cholesterol from total cholesterol. A value >30 mg/dL was considered elevated., Results: The mean LDL-C was 79.1 ± 33.1 mg/dL with 46.4% of all subjects having LDL-C <70 mg/dL and only 16.9% having LDL-C <50 mg/dL. The median remnant cholesterol level was 17.0 mg/dL (interquartile range 12.0-24.0 mg/dL) with only 11.9% of subjects having values >30 mg/dL. Only 4.5% of the patients with LDL-C <70 mg/dL and 2.9% of those with LDL-C <50 mg/dL had elevated remnant cholesterol. These proportions were significantly greater in patients with serum triglycerides >200 mg/dL., Conclusion: Our study shows that in a North-Indian population with CAD, elevated remnant cholesterol was present in only a small proportion. The prevalence of elevated remnant cholesterol decreased further as the LDL-C control improved. These findings suggest that elevated remnant cholesterol may not be a clinically relevant therapeutic target in most patients with LDL-C below the currently recommended goals., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Research Trust of DiabetesIndia (DiabetesIndia) and National Diabetes Obesity and Cholesterol Foundation (N-DOC).

Aims: Aim of the present study was to evaluate the impact of once-weekly semaglutide on different end-points indicative of metabolic control, cardiovascular risk, dietary behavior, and treatment satisfaction in T2DM. Methods: This was a retrospective observational study conducted in a diabetes clinic. Changes in HbA1c, fasting blood glucose (FBG), weight, blood pressure, lipid profile, and number of antihypertensive drugs at 32 weeks (T1) after the first prescription of semaglutide (T0) were analyzed. Furthermore, at T1 patients were asked to fill-in the Diabetes Treatment Satisfaction Questionnaire (DTSQ) and the Control of Eating Questionnaire (COEQ). Results: Overall, 104 patients were identified (mean age 63.6 ± 10.4 years, 58.7% men, diabetes duration 12.7 ± 8.7 years). After 32 weeks of treatment with semaglutide, HbA1c levels were reduced by 1.38%, FBG by − 56.53 mg/dl, weight by 6.03 kg. Systolic and diastolic blood pressure, total, HDL-, LDL-, and non –HDL cholesterol, and triglycerides significantly improved. The number of glucose-lowering and antihypertensive drugs also decreased. At T1, DTSQ score was 32.23 ± 1.44, whereas COEQ indicated low levels of hunger and good control of eating. Conclusions: The study documented benefits of semaglutide on metabolic control and multiple CV risk factors, simplification of therapeutic schemes and high satisfaction with diabetes treatment, and eating behaviors indicative of healthy diet and reduced food intake.

Abstract Suboptimal blood pressure (BP) control in patients with type 2 diabetes is associated with adverse micro‐ and macrovascular complications. This study aimed to investigate the predictors of uncontrolled hypertension in an Iranian population with type 2 diabetes. This is a cross‐sectional study of 2612 patients with type 2 diabetes, including 944 patients with hypertension. Controlled and uncontrolled hypertension were assessed. Multivariate logistic regression modeling was used to determined independent predictors of uncontrolled hypertension. Of 2612 patients with type 2 diabetes, 944 (36.1%) patients had hypertension. Of all patients with hypertension, 580 (61.4%) were still on monotherapy. Uncontrolled hypertension was detected in 536 participants (56.8%). Patients with uncontrolled hypertension had significantly higher body mass index (BMI) (29.8±4.8 vs. 28.6±4.6), waist circumference (99.11±10.95 vs. 96.68±10.92), pulse pressure (67.3±17.3 vs. 48.4±10.7), total cholesterol (177.1±45.5 vs. 164.3±40.5), non‐HDL cholesterol (133.0±43.5 vs. 120.1±38.7), triglycerides (175.7±80.3 vs. 157.4±76.7), and Atherogenic Index of Plasma (AIP) (0.57±0.23 vs. 0.52±0.24) (p 200 mg/dl non‐HDL cholesterol had a significant correlation with uncontrolled hypertension (OR = 4.635, CI95%:1.781–12.064, p = .002). In conclusion, BMI, pulse pressure, total cholesterol, and non‐HDL cholesterol are significant predictors of uncontrolled hypertension in patients with type 2 diabetes. Also, ineffective monotherapy, medical inertia and patients’ non‐compliance were other contributors to the uncontrolled hypertension.

Abstract Background A distorted blood lipid profile is an important risk factor for ischemic heart disease (IHD) but the predictive ability of the different lipid measures has rarely been studied. Our aim was to examine and compare, in a large sample of women, the predictive ability of total cholesterol/HDL cholesterol ratio (TC/HDL-C) and non-HDL-C in relation to IHD, adjusted for age, exercise, smoking, waist-hip ratio, blood pressure, and diabetes mellitus. Methods Between 1995 and 2000, a total of 6537 women aged 50–59 years from the Women’s Health in Lund area (WHILA) study in southern Sweden were included and underwent a baseline examination. The women were followed through national registers for incidence of IHD during a mean follow-up of 17 years. The prediction accuracy was estimated through Harrell’s C and Akaike Information Criterion (AIC). Results Increasing TC/HDL-C as well as non-HDL-C showed strong associations with IHD, with the highest risk in the 5th quintile, where the HR was 2.30 (95% CI: 1.70–3.11) for TC/HDL-C and 1.67 (95% CI: 1.25–2.24) for non-HDL-C, after adjustments. Comparisons using Harrell’s C and AIC indicated that TC/HDL-C has a slightly higher predictive ability than that of non-HDL-C (Harrell’s C 0.62 and 0.59 respectively, p = 0.003 for difference, age-adjusted model; AIC for TC/HDL-C

BackgroundNon-HDL-C is well established causal risk factor for the progression of atherosclerotic cardiovascular disease. However, there remains a controversial pattern of how non-HDL-C relates to all-cause and cardiovascular mortality, and the concentration of non-HDL-C where the risk of mortality is lowest is not defined.MethodsA population-based cohort study using data from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2014. Male participants without statin therapy were divided into the six groups according to non-HDL-C levels (

Purpose of Review: Implementation of intensive LDL cholesterol (LDL-C) lowering strategies and recognition of the role of triglyceride-rich lipoproteins (TRL) in atherosclerosis has prompted re-evaluation of the suitability of current lipid profile measurements for future clinical practice. Recent Findings: At low concentrations of LDL-C (< 1.8 mmol/l/70 mg/dl), the Friedewald equation yields estimates with substantial negative bias. New equations provide a more accurate means of calculating LDL-C. Recent reports indicate that the increase in risk per unit increment in TRL/remnant cholesterol may be greater than that of LDL-C. Hence, specific measurement of TRL/remnant cholesterol may be of importance in determining risk. Non-HDL cholesterol and plasma apolipoprotein B have been shown in discordancy analyses to identify individuals at high risk even when LDL-C is low. Summary: There is a need to adopt updated methods for determining LDL-C and to develop better biomarkers that more accurately reflect the abundance of TRL remnant particles. [ABSTRACT FROM AUTHOR]

To explore whether non-high-density-lipoprotein cholesterol (non-HDL-c) is associated with depression, a total of 26 819 Canadians aged 45–85 from the Canadian Longitudinal Study on Aging (CLSA) were included in analysis. Non-HDL-c, the difference between total-c and HDL-c, was categorized into five levels, i.e.,

Abstract Background Dyslipidemia contributes to the development of nephrolithiasis in adults; however its relationship to urolithiasis in children remains debatable, and will be clarified in the present work. Methods A case–control study was performed involving 58 pediatric patients diagnosed with upper urinary tract stones as well as 351 controls. Age, gender, body mass index (BMI), serum calcium, serum uric acid, blood glucose, blood lipids, and compositions of stones were compared. Results According to the univariate analysis, uric acid was higher (P

Abstract Background Lipid-lowering therapy is guided by Low-density-lipoprotein cholesterol (LDL-c) levels, although the cardiovascular disease (CVD) risk could be better reflected by other lipid parameters. This study aimed at comparing a comprehensive lipid profile between patients with type 2 diabetes mellitus (T2DM) with LDL-c concentration within and above target. Methods A comprehensive lipid profile was characterized in 96 T2DM patients. The European Society of Cardiology/European Atherosclerosis Society (ESC/EAS) 2016 and 2019 Guidelines for the Management of Dyslipidemias were used to define LDL-c targets. Results In this population, only 28.1 and 16.7% of patients had mean LDL-c levels within target, as defined by the 2016 and 2019 guidelines, respectively. Applying the 2016 guidelines criteria, in patients with LDL-c within target, 22, 25 and 44% presented non-high-density lipoprotein cholesterol (non-HDL-c), Apolipoprotein B (ApoB) and oxidized LDL-c levels above the recommended range, respectively, whereas according to the 2019 guidelines criteria, 50, 39 and 44% of the patients with LDL-c within target had elevated high-density lipoprotein cholesterol (HDL-c), ApoB and oxidized LDL-c levels, respectively. LDL-c was strongly correlated with non-HDL-c (r = 0.850), ApoB (r = 0.656) and oxidized LDL-c (r = 0.508). Similarly, there was a strong correlation between non-HDL-c with both ApoB (r = 0.808) and oxidized LDL-c (r = 0.588). Conclusions These findings emphasize the limitations of only considering LDL-c concentration for cardiovascular (CV) risk assessment. Targeting only LDL-c could result in missed opportunities for CV risk reduction in T2DM patients. These data suggest that non-HDL-c, ApoB and oxidized LDL-c levels could be considered as an important part of these patients’ evaluation allowing for a more accurate estimation of CV risk and hopefully better management of these high-risk patients.

Objective: Lipids play key role in coronary atherosclerosis. The role of non-high-density lipoprotein cholesterol (non-HDL-C) in atherosclerotic plaques using intravascular imaging remains unclear. This study aimed to assess its relationship with coronary plaque features using intravascular ultrasound (IVUS) in acute coronary syndrome (ACS)., Methods: A total of 601 patients divided into two groups: normal non-HDL-C≤130 mg/dl (n = 410) and high non-HDL cholesterol >130 mg/dl (n = 191). IVUS performed before coronary intervention., Results: Mean age 53.18 ± 12.29 years. No significant differences in hypertension, diabetes, and smoking between groups. Plaque burden was significantly higher among normal versus high non-HDL-C groups (79.59 ± 9.98 % vs. 81.61 ± 5.39 %; p = 0.001). At minimal luminal site, fibrofatty percentage was higher in normal non-HDL-C group (p = 0.027), while necrotic core greater in high non-HDL-C group (p = 0.033). Segmental analysis, necrotic core was significantly higher in percentage (p = 0.006) and volumes (p = 0.011) in normal versus high non-HDL-C groups. Total cholesterol (r = 0.099, p = 0.015), LDL-C (r = 0.081, p = 0.046), triglycerides (r = 0.083, p = 0.041),and non-HDL-C (r = 0.099, p = 0.015) positively correlated with plaque burden. Total cholesterol (r = 0.115, p = 0.005), LDL-C (r = 0.107, p = 0.009), and non-HDL-C (r = 0.105, p = 0.010) positively correlated with necrotic core volume. Linear regression analysis showed age and non-HDL-C as predictors of higher plaque burden. Multiple linear regression analysis; age, body mass index, and non-HDL-C were predictors of larger necrotic core volume., Conclusion: Non-HDL-C levels were positively associated with plaque burden, measure of extent of atherosclerosis. It is closely associated with and is a predictor of necrotic core volume; a marker of plaque vulnerability. This IVUS study demonstrates potential role of non-HDL-C in causation of plaque in ACS., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Cardiological Society of India.

The article discusses a new approach to assessing cardiovascular risk in clinical practice, presented in the European guidelines 2021. Two novel risk charts (SCORE2 and SCORE2-OP) have been proposed that have undergone significant revision and require significant changes in primary care practice. It has been suggested that in modern conditions their practical introduction is premature, since the healthcare system is not ready for renewal. Therefore, time is needed to adapt it to the practical healthcare conditions and to revise the medical screening protocols, which will require financial costs. The implementation of these recommendations should be taken responsibly so as not to harm the existing system of preventive care.

Background/objective: Obstructive sleep apnea (OSA) is independently associated with dyslipidemia, a surrogate marker of atherosclerosis. Low-density lipoprotein (LDL)-cholesterol is accepted as a major independent risk factor for cardiovascular disease. However, non-high-density lipoprotein (HDL)-cholesterol is a better marker of atherogenic dyslipidemia and recommended as a target of lipid lowering therapy. We aimed to assess the prevalence of atherogenic dyslipidemia, and relationship between OSA severity and serum LDL-cholesterol and non-HDL cholesterol levels in OSA patients.Methods: We retrospectively evaluated treatment naïve 2361 subjects admitted to the sleep laboratory of a university hospital for polysomnography. All subjects' lipid profile including total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides, and non-HDL-cholesterol were measured.Results: Out of 2361 patients (mean age 49.6 ± 11.9 years; 68.9% male, apnea-hypopnea index 36.6 ± 28.4/h), 185 (7.8%) had no OSA and 2176 (92.2%) had OSA. Atherogenic dyslipidemia prevalence was high (57-66%) in OSA patients, and especially increased in severe OSA compared to other groups (p < 0.05). Though total and LDL-cholesterol did not differ between those with and without OSA, non-HDL-cholesterol (p = 0.020), and triglycerides (p = 0.001) were higher and HDL-cholesterol levels (p = 0.018) were lower in OSA patients than non-OSA. Non-HDL-cholesterol was significantly correlated with OSA severity (p < 0.001) and hypoxia parameters (p < 0.01), whereas LDL-cholesterol showed no correlation.Conclusions: Atherogenic dyslipidemia is highly prevalent and non-HDL-cholesterol levels are significantly increased, predominantly in severe OSA patients. Non-HDL-cholesterol but not LDL-cholesterol, is significantly correlated with OSA severity and hypoxia parameters. Therefore, it could be better to use non-HDL-cholesterol, which is a guideline recommended target of lipid therapy, as a marker of atherosclerotic cardiovascular risk in OSA patients.

Background: Not only low-density lipoprotein (LDL) cholesterol but also non-high-density lipoprotein cholesterol (non-HDL-C), very low-density lipoprotein (VLDL) cholesterol (VLDL-C), and intermediate-density lipoprotein (IDL) cholesterol (IDL-C) are reported to be significant risk markers for coronary heart disease (CHD). We reported the relevance of IDL-C to Framingham risk score (F-score), but the present study addressed the relevance of IDL-C to Suita score (S-score), a risk score for coronary heart disease (CHD) developed for the Japanese individuals in addition to F-score.Methods: The cholesterol levels of lipoproteins, including triglyceride (TG)-rich lipoproteins (IDL and VLDL), were measured by an anion exchange high-performance liquid chromatography (AEX-HPLC). This study enrolled 476 men, aged mean 51 years and free of CHD and stroke.Results: Non-HDL-C, IDL-C, and VLDL-C significantly correlated with F-score and S-score. In the multiple stepwise regression analysis, IDL-C as well as body mass index (BMI) significantly correlated with both F-score and S-score in both the total subjects and the subjects without drug therapy. The multivariate logistic analysis with the model composed of BMI and IDL-C as the predictor variables demonstrated that 1 SD increase in IDL-C was an independent predictor for 10-year CHD risk >10% of F-score (OR 1.534, 95% CI 1.266–1.859, p < 0001) and that of S-score (OR 1.372, 95% CI 1.130–1.667, p = 0.0014) in the total subjects. Even in the subjects without the drug therapy, the increased IDL-C, as well as BMI, were significant predictors for 10-year CHD risk >10% of S-score as well as F-score.Conclusion: These results suggest the significant relevance of the increased IDL-C for CHD risk scores in middle-aged men free of CHD and stroke. Further investigations are needed in women and elderly subjects.

Background: The association between obesity, non-HDL cholesterol, and clinical outcomes in subjects with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI) is incompletely understood. The aim of this investigation was to explore the association between body mass index (BMI), non-high density lipoprotein (non-HDL) cholesterol, and long-term follow-up prognosis.Methods: This present study used data obtained by the Cardiovascular Center of Beijing Friendship Hospital Database Bank. We identified 3,780 consecutive AMI populations aged 25–93 years from 2013 to 2020. Participants were categorized as normal weight (18.5 ≤ BMI

Suboptimal blood pressure (BP) control in patients with type 2 diabetes is associated with adverse micro‐ and macrovascular complications. This study aimed to investigate the predictors of uncontrolled hypertension in an Iranian population with type 2 diabetes. This is a cross‐sectional study of 2612 patients with type 2 diabetes, including 944 patients with hypertension. Controlled and uncontrolled hypertension were assessed. Multivariate logistic regression modeling was used to determined independent predictors of uncontrolled hypertension. Of 2612 patients with type 2 diabetes, 944 (36.1%) patients had hypertension. Of all patients with hypertension, 580 (61.4%) were still on monotherapy. Uncontrolled hypertension was detected in 536 participants (56.8%). Patients with uncontrolled hypertension had significantly higher body mass index (BMI) (29.8±4.8 vs. 28.6±4.6), waist circumference (99.11±10.95 vs. 96.68±10.92), pulse pressure (67.3±17.3 vs. 48.4±10.7), total cholesterol (177.1±45.5 vs. 164.3±40.5), non‐HDL cholesterol (133.0±43.5 vs. 120.1±38.7), triglycerides (175.7±80.3 vs. 157.4±76.7), and Atherogenic Index of Plasma (AIP) (0.57±0.23 vs. 0.52±0.24) (p <.05 for all of them) compared to patients with controlled hypertension. Multivariate logistic regression analysis revealed that uncontrolled hypertension was significantly associated with BMI (p =.001), pulse pressure (p =.001), total cholesterol (p =.006), and non‐HDL cholesterol (p =.009). In patients with triglycerides levels > 200 mg/dl non‐HDL cholesterol had a significant correlation with uncontrolled hypertension (OR = 4.635, CI95%:1.781–12.064, p =.002). In conclusion, BMI, pulse pressure, total cholesterol, and non‐HDL cholesterol are significant predictors of uncontrolled hypertension in patients with type 2 diabetes. Also, ineffective monotherapy, medical inertia and patients' non‐compliance were other contributors to the uncontrolled hypertension. [ABSTRACT FROM AUTHOR]

• It is acceptable to screen with nonfasting lipids. • It is recommended to follow up abnormal results with fasting levels. • Non-HDL cholesterol levels can effectively guide ASCVD prevention. • Advanced lipoprotein tests may guide therapeutic decisions in select patients. • Better harmonization of advanced lipid measurement methods is needed. • Recommendations for lipids in clinical care. Lipoprotein measurements are pivotal in the management of patients at risk for atherosclerotic coronary heart disease (CHD) with myocardial infarction and coronary death as the main outcomes, and for atherosclerotic cardiovascular disease (ASCVD), which includes CHD and stroke. Recent developments and changes in guidelines affect optimization of using lipid measures as cardiovascular biomarkers. This scientific statement reviews the pre-analytical, analytical, post-analytical, and clinical aspects of lipoprotein measurements. Highlights include the following: i) It is acceptable to screen with nonfasting lipids. ii) non-high-density lipoprotein HDL-cholesterol (non-HDL-C) is measured reliably in either the fasting or the nonfasting state and can effectively guide ASCVD prevention. iii) low density lipoprotein cholesterol (LDL-C) can be estimated from total cholesterol, high density lipoprotein cholesterol (HDL-C), and triglyceride (TG) measurements. For patients with LDL-C>100 mg/dL and TG ≤150 mg/dL it is reasonable to use the Friedewald formula. However, for those with TG 150-400 mg/dL the Friedewald formula for LDL-C estimation is less accurate. The Martin/Hopkins method is recommended for LDL-C estimation throughout the range of LDL-C levels and up to TG levels of 399 mg/dL. For TG levels ≥400 mg/dL LDL-C estimating equations are currently not recommended and newer methods are being evaluated. iv) When LDL-C or TG screening results are abnormal the clinician should consider obtaining fasting lipids. v) Advanced lipoprotein tests using apolipoprotein B (apoB), LDL Particle Number (LDL-P) or remnant cholesterol may help to guide therapeutic decisions in select patients, but data are limited for patients already on lipid lowering therapy with low LDL-C levels. Better harmonization of advanced lipid measurement methods is needed. Lipid measurements are recommended 4-12 weeks after a change in lipid treatment. Lipid laboratory reports should denote desirable values and specifically identify extremely elevated LDL-C levels (≥190 mg/dL at any age or ≥160 mg/dL in children) as severe hypercholesterolemia. Potentially actionable abnormal lipid test results, including fasting triglycerides (TG) ≥500 mg/dL, should be reported as hypertriglyceridemia. Appropriate use and reporting of lipid tests should improve their utility in the management of persons at high risk for ASCVD events. [ABSTRACT FROM AUTHOR]

Background: Hypertension and non–high-density lipoprotein cholesterol (non-HDL-c) measure is a useful evaluation tool to assess heart disease risk. Increasing physical activity (PA) is considered to reduce blood pressure (BP) and non-HDL-c in patients with hypertension. Objective: This study assesses the influence of moderate and regular PA on non-HDL cholesterol in essential hypertension. Subjects and methods: We studied 100 patients of either gender, aged 40–69 years of stage 2 essential hypertension in this interventional study. Patients were enrolled for 12 weeks of PA intervention (10,000 footsteps per day) and were followed at 15 days interval in the first month and after that 1-month duration. Lipid profile was estimated at baseline and at the final assessment visit (after 12 weeks). Results: The data included in this study confirm the beneficial effects of regular PA on non-HDL-c levels (P < 0.000001). It was found that after 12 weeks of intervention program, the cholesterol, triglycerides; low-density lipoprotein cholesterol (LDL), very low-density lipoprotein cholesterol (VLDL), and non-HDL-c were lowered from 276.53 to 194.19, 191.17 to 110.58, 196.07 to 120.72, 38.23 to 22.12, and 234.32 to 142.84, respectively. It was also noted that high-density lipoprotein cholesterol (HDL) was increased from 42.21 to 51.35 following the interventional program. All the results were highly significant (P < 0.000001). Conclusions: A non-pharmacological activity like PA is beneficial for better management of hypertension to avoid cardiovascular co-morbidities. Twelve weeks of physical exercise program (walking of 10,000 footsteps/day) decreases the risk associated with BP elevation by improving non-HDL-c in hypertensive patients.

Abstract Background Probiotics incorporated into dairy products have been shown to reduce total (TC) and LDL cholesterolemia (LDL-C) in subjects with moderate hypercholesterolemia. More specifically, probiotics with high biliary salt hydrolase activity, e.g. Bifidobacterium longum BB536, may decrease TC and LDL-C by lowering intestinal cholesterol reabsorption and, combined with other nutraceuticals, may be useful to manage hypercholesterolemia in subjects with low cardiovascular (CV) risk. This study was conducted to evaluate the efficacy and safety of a nutraceutical combination containing Bifidobacterium longum BB536, red yeast rice (RYR) extract (10 mg/day monacolin K), niacin, coenzyme Q10 (Lactoflorene Colesterolo®). The end-points were changes of lipid CV risk markers (LDL-C, TC, non-HDL-cholesterol (HDL-C), triglycerides (TG), apolipoprotein B (ApoB), HDL-C, apolipoprotein AI (ApoAI), lipoprotein(a) (Lp(a), proprotein convertase subtilisin/kexin type 9 (PCSK9)), and of markers of cholesterol synthesis/absorption. Methods A 12-week randomized, parallel, double-blind, placebo-controlled study. Thirty-three subjects (18–70 years) in primary CV prevention and low CV risk (SCORE: 0–1% in 24 and 2–4% in 9 subjects; LDL-C: 130–200 mg/dL) were randomly allocated to either nutraceutical (N = 16) or placebo (N = 17). Results Twelve-week treatment with the nutraceutical combination, compared to placebo, significantly reduced TC (− 16.7%), LDL-C (− 25.7%), non-HDL-C (− 24%) (all p

Purpose: Type 2 diabetes mellitus (T2DM) is a major risk factor for cardiovascular diseases (CVD). The plasma atherogenic index (PAI) has been suggested as a novel marker of atherosclerosis and coronary heart disease. The present study is conducted to investigate the relationship between glycated hemoglobin (HbA1c), non-HDL (high-density lipoprotein) cholesterol, and atherogenic index within patients with T2DM. Materials and methods: A total of 4252 patients with T2DM were screened retrospectively and parameters including glucose, HbA1c, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglyceride, TSH, age, and gender were recorded. Non-HDL cholesterol and PAI were calculated as follows: PAI = TG ÷ HDL cholesterol non − HDL = total cholesterol − HDL cholesterol Results: Mean age was 57.06 ± 11.39 years. Mean HbA1c was 8.49 ± 1.86%, PAI ratio was 4.12 ± 3.88 mg/dl, and mean non-HDL cholesterol was 156.50 ± 45.39 mg/dl. Non-HDL cholesterol (r = 0.427; p < 0.001), HbA1c (r = 0.163; p < 0.001), and glucose (r = 0.154; p < 0.001) showed a significantly positive correlation with PAI. Conclusion: Although a respectable attention is drawn to non-HDL cholesterol based on the present data, PAI may have a stronger relationship with HbA1c in patients with T2DM. PAI may be beneficial in predicting patients who have high risk for CVD in clinical practice. [ABSTRACT FROM AUTHOR]

Background: A distorted blood lipid profile is an important risk factor for ischemic heart disease (IHD) but the predictive ability of the different lipid measures has rarely been studied. Our aim was to examine and compare, in a large sample of women, the predictive ability of total cholesterol/HDL cholesterol ratio (TC/HDL-C) and non-HDL-C in relation to IHD, adjusted for age, exercise, smoking, waist-hip ratio, blood pressure, and diabetes mellitus.Methods: Between 1995 and 2000, a total of 6537 women aged 50-59 years from the Women's Health in Lund area (WHILA) study in southern Sweden were included and underwent a baseline examination. The women were followed through national registers for incidence of IHD during a mean follow-up of 17 years. The prediction accuracy was estimated through Harrell's C and Akaike Information Criterion (AIC).Results: Increasing TC/HDL-C as well as non-HDL-C showed strong associations with IHD, with the highest risk in the 5th quintile, where the HR was 2.30 (95% CI: 1.70-3.11) for TC/HDL-C and 1.67 (95% CI: 1.25-2.24) for non-HDL-C, after adjustments. Comparisons using Harrell's C and AIC indicated that TC/HDL-C has a slightly higher predictive ability than that of non-HDL-C (Harrell's C 0.62 and 0.59 respectively, p = 0.003 for difference, age-adjusted model; AIC for TC/HDL-C < AIC for non-HDL-C).Conclusions: TC/HDL-C ratio and non-HDL-C are both clinical predictors for IHD in middle-aged women. The results indicate that the predictive ability of TC/HDL-C was higher than that of non-HDL-C; however, non-HDL-C was linearly related to IHD (p = 0.58) and may be easier to calculate and interpret in clinical practice, for early identification of future IHD in women.

Background: In cholesterol guidelines, low-density lipoprotein (LDL) cholesterol remains the primary target while apolipoprotein B (apoB) and non-high-density lipoprotein (non-HDL) cholesterol are secondary targets.Objectives: This study sought to determine if elevated apoB and/or non-HDL cholesterol are superior to elevated LDL cholesterol in identifying statin-treated patients at residual risk of all-cause mortality and myocardial infarction.Methods: In total, 13,015 statin-treated patients from the Copenhagen General Population Study were included with 8 years median follow-up. Cox regressions among apoB, non-HDL cholesterol, and LDL cholesterol, respectively, and all-cause mortality or myocardial infarction were examined on continuous scales by restricted cubic splines and by categories of concordant and discordant values defined by medians.Results: High apoB and non-HDL cholesterol were associated with increased risk of all-cause mortality and myocardial infarction, whereas no such associations were found for high LDL cholesterol. Compared with concordant values below medians, discordant apoB above the median with LDL cholesterol below yielded hazard ratios of 1.21 (95% confidence interval [CI]: 1.07 to 1.36) for all-cause mortality and 1.49 (95% CI: 1.15 to 1.92) for myocardial infarction. Corresponding values for high non-HDL cholesterol with low LDL cholesterol were 1.18 (95% CI: 1.02 to 1.36) and 1.78 (95% CI: 1.35 to 2.34). In contrast, discordant high LDL cholesterol with low apoB or non-HDL cholesterol was not associated with increased risk of all-cause mortality or myocardial infarction. Also, discordant high apoB with low non-HDL cholesterol yielded hazard ratios of 1.21 (95% CI: 1.03 to 1.41) for all-cause mortality and of 0.93 (95% CI: 0.62 to 1.40) for myocardial infarction. Furthermore, dual discordant apoB and non-HDL cholesterol above the medians with LDL cholesterol below presented hazard ratios of 1.23 (95% CI: 1.07 to 1.43) for all-cause mortality and 1.82 (95% CI: 1.37 to 2.42) for myocardial infarction.Conclusions: In statin-treated patients, elevated apoB and non-HDL cholesterol, but not LDL cholesterol, are associated with residual risk of all-cause mortality and myocardial infarction. Discordance analysis demonstrates that apoB is a more accurate marker of all-cause mortality risk in statin-treated patients than LDL cholesterol or non-HDL cholesterol, and apoB in addition is a more accurate marker of risk of myocardial infarction than LDL cholesterol.

The increasing burden of diabetes mellitus is one of the major public health challenges in African countries, including Ethiopia. This is the first study aimed to identify factors associated with prediabetes and diabetes defined by both fasting blood glucose and glycated hemoglobin in Ethiopians. We analyzed data of a cross-sectional survey (1372 adults aged 25-64 years) conducted between October 2015 and February 2016; multinomial logistic regression models were applied. Abdominal obesity, total cholesterol, and non–high-density lipoprotein cholesterol were independently associated with prediabetes and diabetes in both sexes. Increased triglycerides and religious fasting practices were independently associated with prediabetes and diabetes only in men; hypertension was associated with prediabetes and diabetes only in women, while high-density lipoprotein cholesterol was not associated with prediabetes and diabetes in either sex. Sex differences in the association of triglycerides, hypertension, and dietary habit suggest that different approaches of lifestyle modification may be required for men and women.

Abstract Background Excessive lipid depositing in liver cells could induce pathophysiological development of liver. Our study aimed to assess whether non-HDL cholesterol to HDL-cholesterol ratio (NonHDLc/HDLc) is an independent risk factor for liver function tests (LFTs) abnormalities in geriatric population. Methods We enrolled 1745 eligible subjects (714 males, 1031 females) with normal liver function tests at baseline who participated in annual health checkup for liver disease in 2015. Logistic regression models were used to examine the independent relationship between NonHDLc/HDLc ratio and LFTs abnormalities. Results After one year follow-up, there were 6.1% (n = 107) participants developed new-onset LFTs abnormalities in 2016. Equally dividing participants into tertiles according to their baseline NonHDLc/HDLc ratio levels, we found compared with tertile 1, the multivariable-adjusted ORs (95% CIs) for new-onset LFTs abnormalities of tertile 3 were 2.85 (1.18–6.93), P = 0.021. In stratified analysis, compared with controls, the correlation between NonHDLc/HDLc ratio and incidence of LFTs abnormalities was more remarkable in female individuals, BMI > 24 individuals and free of diabetes individuals. Conclusion Our study suggests that NonHDLc/HDLc ratio is an independent risk factor for LFTs abnormalities in geriatric population, and assessment of NonHDLc/HDLc ratio may help early identify high risk people of liver diseases.

Non-high density lipoprotein cholesterol (non-HDLC) represents the cholesterol in triglyceride-rich lipoproteins (TRL) and low-density lipoproteins (LDL). Apolipoprotein B (apoB) reflects the number of TRL and LDL particles. In hypertriglyceridemia (HTG), there is triglyceride (TG) enrichment of TRLs, and also a substantial increase of cholesterol in larger TRLs that considerably augments the non-HDLC value. Therefore, in HTG, non-HDLC could increase disproportionately with respect to apoB. We aimed to compare the relative effect of the full range of mild, moderate, and severe HTG on the status of non-HDLC and apoB as cardiovascular disease (CVD) risk markers. Analysis of lipid profile data from 4347 patients in a Lipid Clinic cohort with baseline fasting lipid profiles documented prior to starting lipid-lowering medications. The correlation between non-HDLC and apoB was assessed in intervals of increasing TG. Non-HDLC and apoB were analyzed at each TG level using comparative CVD risk equivalent categories and assessed for divergence and discordance. With increasing TG levels: (1) the correlation between non-HDLC and apoB diminished progressively, (2) non-HDLC levels increased continuously, whereas apoB levels plateaued after an initial increase up to TG of ~ 4.0-5.0 mmol/L (~354-443 mg/dL), (3) there was divergence in the stratification of non-HDLC and apoB into CVD risk equivalent categories. Non-HDLC and apoB should not be viewed as interchangeable CVD risk markers in the presence of severe HTG. This has never been tested. With increasing HTG severity, discordance between non-HDLC and apoB can cause clinically important divergence in CVD risk categorization. • As TG increases, the correlation between non-HDLC and apoB decreases progressively. • In HTG, discordant non-HDLC and apoB causes divergence in CVD risk categorization. • Non-HDLC and apoB should not be viewed as interchangeable CVD risk markers in HTG.

Aims The 2019 vs. 2016 European Society of Cardiology/European Atherosclerosis Society (ESC/EAS) dyslipidaemia guidelines contains new recommendations for primary prevention with statins; however, the potential impact of these changes is unclear. We compared the 2019 and 2016 guidelines regarding statin eligibility and potential impact on prevention of atherosclerotic cardiovascular disease (ASCVD) in the general population. Methods and results We examined 45 750 individuals aged 40–75 from the Copenhagen General Population Study, all free of ASCVD and statin use at baseline. During the 9.2-year follow-up, 3337 experienced ASCVD (myocardial infarction, stroke, and cardiovascular death). For Class I/A recommendations, 32.3% (95% confidence interval: 31.8–32.7) and 15.4% (15.1–15.7) of individuals were statin eligible according to the 2019 and 2016 guidelines. The increased statin eligibility by the 2019 guidelines was explained by lower low-density lipoprotein cholesterol (LDL-C) thresholds alone (explaining 33.2%), older age range alone (49.4%), older age range in combination with lower LDL-C thresholds (14.7%), and updated SCORE risk algorithm (2.8%). If fully implemented, the estimated percentage of ASCVD events that can be prevented by using high-intensity statins for 10 years were 25% and 11% with the 2019 and 2016 guidelines. Mainly because of older age range in the 2019 guidelines, the corresponding estimated numbers needed to treat (NNT) to prevent one ASCVD event were 19 and 20. Conclusion Due to lower LDL-C threshold and older age range, the 2019 vs. 2016 ESC/EAS guidelines doubles the number of individuals eligible for primary prevention with statins. This considerably improves the potential for ASCVD prevention in the general population, with similar NNT to prevent one event.

Background: Dyslipidemia contributes to the development of nephrolithiasis in adults; however its relationship to urolithiasis in children remains debatable, and will be clarified in the present work.Methods: A case-control study was performed involving 58 pediatric patients diagnosed with upper urinary tract stones as well as 351 controls. Age, gender, body mass index (BMI), serum calcium, serum uric acid, blood glucose, blood lipids, and compositions of stones were compared.Results: According to the univariate analysis, uric acid was higher (P < 0.01) but serum calcium lower in the stone group than the control (P < 0.05). As for the blood lipids, non-high-density lipoprotein cholesterol (non-HDL-c) was significantly higher in the stone group as compared to the control (P < 0.01), while total cholesterol, triglycerides, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol did not show statistical difference between the two groups. In the multivariate analysis, only non-HDL-c and serum uric acid were increased in the stone group (P = 0.003 and P = 0.008). In the stone compositions' analysis, serum uric acid and non-HDL-c were associated with percentage of uric acid and pure calcium oxalate stones, respectively.Conclusion: Non-high-density lipoprotein cholesterol may act as a lipid risk factor for urolithiasis in children.

Purpose of Review: Guidelines propose using non-HDL cholesterol or apolipoprotein (apo) B as a secondary treatment target to reduce residual cardiovascular risk of LDL-targeted therapies. This review summarizes the strengths, weaknesses, opportunities, and threats (SWOT) of using apoB compared with non-HDL cholesterol. Recent Findings: Non-HDL cholesterol, calculated as total-HDL cholesterol, includes the assessment of remnant lipoprotein cholesterol, an additional risk factor independent of LDL cholesterol. ApoB is a direct measure of circulating numbers of atherogenic lipoproteins, and its measurement can be standardized across laboratories worldwide. Discordance analysis of non-HDL cholesterol versus apoB demonstrates that apoB is the more accurate marker of cardiovascular risk. Baseline and on-treatment apoB can identify elevated numbers of small cholesterol-depleted LDL particles that are not reflected by LDL and non-HDL cholesterol. Summary: ApoB is superior to non-HDL cholesterol as a secondary target in patients with mild-to-moderate hypertriglyceridemia (175–880 mg/dL), diabetes, obesity or metabolic syndrome, or very low LDL cholesterol < 70 mg/dL. When apoB is not available, non-HDL cholesterol should be used to supplement LDLC. [ABSTRACT FROM AUTHOR]
