Effect of Low High-Density Lipoprotein Level on Endothelial Activation and Prothrombotic Processes in Coronary Artery Disease-A Pilot Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19148637. [PMID: 35886486 PMCID: PMC9316205 DOI: 10.3390/ijerph19148637] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Revised: 07/13/2022] [Accepted: 07/14/2022] [Indexed: 11/17/2022]
Abstract
High-density lipoproteins (HDL) play an important role in the prevention of atherosclerosis. The aim of the study was to assess the relationship between serum HDL-C concentration and proinflammatory/prothrombic activation in coronary artery disease (CAD) patients. The study group included 27 acute myocardial infarction (AMI) patients and 30 stable angina pectoris (SA) patients. The control group consisted of 23 people without cardiac symptoms. In the AMI and SA groups, a lower HDL-C and a higher LDL-C/HDL-C index were observed. The SA patients had lower total cholesterol, LDL-C, sE-selectin ligand, as well as higher triglycerides and CD40 concentration in comparison with both the control and AMI groups. A higher von Willebrand Factor and intercellular adhesion molecule-1 were found in both study groups. Low HDL-C concentration in the CAD patients may intensify pro-inflammatory endothelial activation and prothrombotic processes. A low concentration of HDL-C and a high value of the LDL-C/HDL-C index seem to be better indices of atherogenic processes than the LDL-C concentration alone.

Abstract
AIMS To develop and validate a nomogram prediction model for the risk of diabetic foot in patients with type 2 diabetes mellitus (T2DM) and evaluate its clinical application value. METHODS We retrospectively collected clinical data from 1,950 patients with T2DM from the Second Affiliated Hospital of Xi'an Jiaotong University between January 2012 and June 2021. The patients were divided into training cohort and validation cohort according to the random number table method at a ratio of 7:3. The independent risk factors for diabetic foot among patients with T2DM were identified by multivariate logistic regression analysis. Then, a nomogram prediction model was developed using the independent risk factors. The model performances were evaluated by the area under the receiver operating characteristic curve (AUC), calibration plot, Hosmer-Lemeshow test, and the decision curve analysis (DCA). RESULTS Multivariate logistic regression analysis indicated that age, hemoglobin A1c (HbA1c), low-density lipoprotein (LDL), total cholesterol (TC), smoke, and drink were independent risk factors for diabetic foot among patients with T2DM (P < 0.05). The AUCs of training cohort and validation cohort were 0.806 (95% CI: 0.775∼0.837) and 0.857 (95% CI: 0.814∼0.899), respectively, suggesting good discrimination of the model. Calibration curves of training cohort and validation cohort showed a favorable consistency between the predicted probability and the actual probability. In addition, the P values of Hosmer-Lemeshow test for training cohort and validation cohort were 0.826 and 0.480, respectively, suggesting a high calibration of the model. When the threshold probability was set as 11.6% in the DCA curve, the clinical net benefits of training cohort and validation cohort were 58% and 65%, respectively, indicating good clinical usefulness of the model. CONCLUSION We developed and validated a user-friendly nomogram prediction model for the risk of diabetic foot in patients with T2DM. Nomograms may help clinicians early screen and identify patients at high risk of diabetic foot.

[PMID: 32449038 PMCID: PMC7246270 DOI: 10.1186/s43044-020-00057-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2019] [Accepted: 04/27/2020] [Indexed: 12/20/2022] Open
Abstract
Background The apolipoprotein B/apolipoprotein A-I ratio was shown to be strongly related to the risk of myocardial infarction in several large-scale studies. The current study aimed at exploring the diagnostic and short-term prognostic values of apolipoprotein B/apolipoprotein A-I ratio in patients presenting with non-ST segment elevation acute coronary syndrome. One hundred patients with non-ST segment elevation acute coronary syndrome were prospectively enrolled, in addition to a matched group of 100 patients with chronic stable angina. Serum levels of total cholesterol, low-density lipoprotein, high-density lipoprotein, triglycerides, and apolipoproteins B and A-I were quantified in both groups. Patients with non-ST segment elevation acute coronary syndrome underwent coronary angiography. Results The mean age of the study population was 57 ± 6 years, 65% being males. The non-ST segment elevation acute coronary syndrome group showed significantly unfavorable lipid profile parameters, including apolipoprotein B/apolipoprotein A-I ratio. Higher apolipoprotein B/apolipoprotein A-I ratio was associated with more coronaries showing significant stenosis and more complex lesion morphology. Receiver operating characteristic curve analysis reached an optimal cut-off value of 0.93 for diagnosis of non-ST segment elevation acute coronary syndrome (sensitivity 70% and specificity 88%) and 0.82 for predicting the presence of multi-vessel disease (sensitivity 90% and specificity 97%). Conclusion Apolipoprotein B/apolipoprotein A-I ratio is a useful tool of risk assessment in patients presenting with non-ST segment elevation acute coronary syndrome including prediction of coronary multivessel affection. Apolipoprotein B/apolipoprotein A-I ratio was shown to be strongly related to risk of myocardial infarction. Higher ratios of apolipoprotein B/apolipoprotein A-I were recorded in NSTE-ACS patients (versus stable angina patients). Higher apolipoprotein B/apolipoprotein A-I ratios were associated with more diseased coronaries and complex lesions. Apolipoprotein B/apolipoprotein A-I ratio is a useful tool for acute risk assessment in cardiac ischemic patients.

[PMID: 28502501 DOI: 10.1016/j.jacl.2017.01.020] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2016] [Revised: 11/29/2016] [Accepted: 01/31/2017] [Indexed: 01/13/2023]
Abstract
BACKGROUND Both apolipoprotein B (apoB) and non-high-density lipoprotein cholesterol (non-HDL-C) are accepted as alternative risk factors or targets for lipid-lowering therapy, which correlate more strongly with cardiovascular events than low-density lipoprotein cholesterol. OBJECTIVE The aim of this cross-sectional study was to evaluate the differences in plasma levels of plasminogen activator inhibitor-1 (PAI-1) and of von Willebrand factor (vWF) as endothelial hemostatic markers and carotid intima-media thickness (C-IMT) as a morphologic marker for atherosclerotic vascular disease among dyslipidemic individuals with apoB levels higher, estimated or lower based on regression equation of apoB vs non-HDL-C. METHODS A total of 594 dyslipidemic subjects without atherosclerotic manifestation were divided into 3 groups (according to tertiles of apoB levels above, within, and below the line of identity): H-apoB (n = 200), E-apoB (n = 194), and L-apoB (n = 200). PAI-1, vWF, C-IMT and lipids, anthropometric parameters, markers of insulin resistance, and inflammation were measured. Differences in variables between groups were analyzed using analysis of variance. RESULTS There was a strong association between apoB and non-HDL-C. The correlations of apoB and of non-HDL-C with markers of endothelial damage and C-IMT were very similar. Despite these facts, individuals with higher apoB levels had significantly higher levels of PAI-1 compared with individuals with estimated (P < .05) or lower apoB (P < .001). There were no significant differences in vWF, C-IMT, markers of insulin resistance, obesity, and inflammation. CONCLUSION Individuals with apoB higher than predicted by non-HDL-C had significantly higher levels of PAI-1, which may contribute to the increased risk of future atherothrombotic events.

Abstract
[Purpose] The objective of this study was to confirm whether consistent aerobic exercise
has an effect on the apolipoprotein B/apolipoprotein A-1 ratio or reduces the risk of
cardiovascular disease in obese women. [Subjects and Methods] The participants included 32
obese women between the ages of 40 and 49. Subjects were randomly divided into two groups
(n = 16 in each group): the control group and the exercise group. The exercise program in
this study corresponded to an intensity of 50 to 60% of the maximum volume of minute
oxygen consumption and was performed three times per week over 12 weeks. Physical
measurements, measurement of cardiorespiratory fitness and blood pressure, and blood
collection were done before and after the 12 weeks of exercise at the same time and under
the same conditions. [Results] Based on the results of this study, there were significant
interaction effects in both time and group weight, for body mass index, percent body fat,
maximum volume of minute oxygen consumption, high-density lipoprotein cholesterol, and the
apolipoprotein B/apolipoprotein A-1 ratio. Moreover, waist circumference, total
cholesterol, and the atherogenic index decreased significantly after 12 weeks of aerobic
exercise. [Conclusion] Regular aerobic exercise effectively improved cardiovascular risk
factors and decreased the obesity index in obese women.

Abstract
OBJECTS To investigate the relationship between plasma levels of pigment epithelium-derived factor (PEDF) and acute coronary syndrome (ACS) in the Chinese Han population. METHODS Plasma PEDF levels were measured in 200 consecutive ACS patients and 160 age- and sex-matched healthy control subjects. Logistic regression analysis was performed to determine whether PEDF was an independently protective factor against ACS. All ACS patients were followed up for 6 months and the short-term major adverse cardiovascular events (MACE) were obtained: cardiac death and recurrent angina. RESULTS The ACS patients showed notably lower plasma PEDF levels relative to the control group (7.31 ± 2.21 vs. 8.44 ± 2.13 μg/ml, respectively, p = 0.001). Logistic regression analysis revealed that PEDF had a significant protective effect against ACS (OR = 0.76, 95% CI 0.623-0.935, p = 0.01). After 6 months of follow-up, we found that the mean PEDF concentration of the patients with short-term MACE was lower than the patients without (6.05 ± 2.18 vs. 7.52 ± 2.07 µg/ml, p = 0.031). The Kaplan-Meier survival curves suggested that patients with plasma PEDF levels <7.00 µg/ml showed a lower survival trend than those in the higher group, but the difference was not significant (p = 0.477). CONCLUSIONS Our study indicates that plasma PEDF levels are significantly lower in ACS patients than in controls, and lower PEDF levels are further associated with adverse cardiac outcomes after ACS.

Abstract
BACKGROUND Low-density lipoprotein cholesterol (LDL-C) remains the primary target of therapy in most strategies of dyslipidaemia management focused on cardiovascular disease prevention. Different guidelines have identified specific LDL-C cut-off points as targets for therapeutic intervention. Many clinical situations characterised by dyslipidaemia and elevated triglycerides are common in our environment and in overall industrialised countries. Thus, lipid goals based only on LDL-C could misclassify an important percentage of subjects. The objective of the present study was to establish cut-off point values for apoB and non-HDL-C in relation to the identified LDL-C cut-off points for cardiovascular risk in a South European population. METHODS We performed a cross-sectional study including 1501 subjects (770 women and 731 men) between 18 and 80 years of age. Samples were collected after 12-14 h of fasting. Cholesterol, HDL-C, triglycerides and apoB levels were measured using direct methods. LDL-C was calculated by the Friedewald formula. Non-HDL-C was calculated as total cholesterol minus HDL-C. RESULTS The Spearman's rank correlations between apoB and LDL-C (r 0.86, p < 0.0001), and between apoB and non-HDL-C (r 0.91, p < 0.0001) were both significant. The proposed cut-off points for apoB, according to LDL-C goals (70, 100, 130 and 160 mg/dl) in our population are 70, 80, 100 and 115 mg/dl respectively. The proposed cut-off values for non-HDL-C are 100, 120, 150 and 190 mg/dl respectively. CONCLUSION The established LDL-C cut-off values could not be accurate to estimate cardiovascular risk in subjects with mild hypertriglyceridaemia, as frequently occurs in our Mediterranean population. To take into consideration the burden of atherogenic particles and better classify patients at risk we propose cut-off values for apoB or the equivalent for non-HDL-C. Prospective trials including cardiovascular variables are needed to validate our assumption.

Abstract
Objective. To investigate whether assessment of C-reactive protein (CRP) and apolipoproteins, besides the traditional lipid profile, enhances the assessment process for the risk of acute coronary syndrome (ACS). Methods. The study group consisted of 220 consecutive patients admitted to hospital within the first 6 hours from the onset of chest pain. Patients were diagnosed with unstable angina (n = 96), non-ST-elevation myocardial infarction (NSTEMI; n = 57), or ST-elevation myocardial infarction (STEMI; n = 67). ACS patients were compared with 116 healthy volunteers in a case-control study. The serum was assayed on admission for CRP, apolipoproteins ApoAI and ApoB100, and lipid parameters. Results. The highest concentrations of CRP were found in NSTEMI and STEMI, with a median value four-fold higher in ACS patients than in controls (P < 0.0001). Only CRP significantly increased the probability of ACS development (adjusted odds ratio for a 1 mg/L increase 1.90; 95% confidence interval [CI] 1.34–2.89) and explained 90% of the variation for ACS development. Similarly, we demonstrated the highest diagnostic accuracy for CRP among all investigated markers (area under the curve 0.80; 95% CI 0.75–0.85). Conclusions. Our study indicates that CRP superiorly to apolipoproteins and lipid profile facilitates the risk stratification for ACS occurrence.

Abstract
BACKGROUND Long-term dietary weight loss results in complex metabolic changes. However, its effect on cholesterol metabolism in obese subjects is still unclear. OBJECTIVE We assessed the effects of 2 y of weight loss achieved with various diet regimens on phytosterols (markers of intestinal cholesterol absorption), lanosterol (marker of de novo cholesterol synthesis), and changes in apolipoprotein concentrations. DESIGN We conducted the 2-y Dietary Intervention Randomized Controlled Trial (DIRECT-a study of low-fat, Mediterranean, and low-carbohydrate diets). We assessed circulating phytosterol and lanosterol concentrations and their ratios to cholesterol and apolipoproteins A-I and B-100 in 90 DIRECT participants at 0, 6, and 24 mo. RESULTS We observed a significant upregulation of the markers of cholesterol absorption (campesterol: +16.8%, P < 0.001) and a downregulation of the markers of cholesterol synthesis (lanosterol: -16.5%, P = 0.008) during the active weight-loss phase (first 6 mo, weight loss of 5%, 6%, and 10% in the 3 diet groups, respectively), followed by a rebound (campesterol: -6.2%, P = 0.045; lanosterol: +43.7%, P < 0.001) during the next 18 mo (weight gain of 1%, 1%, and 2% in the 3 diet groups, respectively). HDL cholesterol continuously increased during the study (17.0%, P < 0.001), whereas LDL cholesterol remained constant. At the end of the 24-mo follow-up period, campesterol (P < 0.001) and lanosterol (P = 0.016) amounts were significantly higher than baseline values. The concentration of apolipoprotein B-100 correlated with cholesterol metabolism (ρ = 0.299 and P = 0.020 for lanosterol; ρ = -0.105 and NS for campesterol), and the homeostasis model assessment of insulin resistance correlated with lanosterol (ρ = 0.09, P = 0.001). CONCLUSIONS Long-term weight loss is related to a characteristic response suggestive of altered cholesterol and apolipoprotein metabolism. Various diets have a similar effect on these effects. DIRECT is registered at clinicaltrials.gov as NCT00160108.

Abstract
The low-density lipoprotein cholesterol to apolipoprotein B (LDL-C/apo B) ratio is associated with cardiovascular risk factors and the prevalence of metabolic syndrome. The aim of this study was to assess the relationship between LDL-C/apo B ratio and metabolic syndrome in Korean men. This study included 499 men (mean age, 49.1 years) without metabolic syndrome at baseline who were followed for an average of 2.9 years. Subjects were divided into 4 groups according to baseline LDL-C/apo B ratio quartiles: greater than 1.243 in group I, 1.164 to 1.243 in group II, 1.070 to 1.163 in group III, and less than 1.070 in group IV. The incidence of metabolic syndrome at follow-up was compared according to LDL-C/apo B ratio group. Metabolic syndrome was defined using the National Cholesterol Education Program Adult Treatment Panel III criteria. The overall incidence of metabolic syndrome was 9.6%: 1.6% in the highest quartile (group I), 9.7% in group II, 11.2% in group III, and 16.0% in the lowest quartile (group IV) (P = .001). In multivariable regression analysis model adjusting for age, lifestyle status, homeostasis model assessment of insulin resistance, LDL-C, and high-sensitivity C-reactive protein, groups II, III, and IV had significantly increased odds ratio for the incidence of metabolic syndrome compared with the highest LDL-C/apo B quartile (group I). The LDL-C/apo B ratio is independently associated with metabolic syndrome in Korean men, indicating that this ratio may provide additional information when assessing cardiometabolic risks and predicting future development of metabolic syndrome.

Abstract
BACKGROUND Data about predictors of intima-media thickness (IMT) of common carotid artery (CCA) in asymptomatic subjects with newly detected severe hypercholesterolemia is scarce. AIM This research is aimed at studying the predictors of the IMT of CCA among basic atherogenic risk biomarkers - lipid [total cholesterol (TC), triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein (LDL) cholesterol, Apolipoprotein-B, Apolipoprotein-Ai, Apolipoprotein-B/A(1) index] and non-lipid, [asymmetric dimethylarginine (ADMA), total homocysteine, cell adhesion molecules] in asymptomatic subjects with newly detected severe hypercholesterolemia. METHODS Two hundred and fifty asymptomatic patients with severe, newly hypercholesterolemia and 200 controls were evaluated. Hypercholesterolemia was defined as TC > 7.5 mm and LDL cholesterol > 4.9 mm. The ADMA and cell adhesion molecules were determined by ELISA and total homocysteine by high-performance liquid chromatography. RESULTS There was significant difference between the two groups in respect to all lipid biomarkers (P<0.001). Hypercholesterolemic patients had significantly higher level of ADMA, sVCAM-1, sICAM-1, IMT (P<0.001), whereas no significant difference was found between two groups with respect to total homocysteine, P-selectin and E-selectin (P>0.05). A strong positive correlation between IMT mean and age (r(xy) = 0.714; P<0.001), Apolipoprotein-B (r(xy) = 0.706; r(xy) < 0.001), Apolipoprotein-B/A(1) (r(xy) = 0.324; P<0.001), ADMA (r(xy) = 0.603; P<0.001) was found. The subsequent linear and multiple regression analysis selected age and Apolipoprotein-B as most significant factors in relation to IMT mean. Apolipoprotein-B is a better factor for assessment of risk, as LDL cholesterol underestimates the risk in asymptomatic subjects with newly detected severe hypercholesterolemia, until more rapid and feasible methods for measurement of small and dense LDL are available.

Abstract
BACKGROUND Metabolic syndrome is highly prevalent in the general population. Small dense low-density lipoprotein (sd-LDL) particles have been considered as a risk marker in metabolic syndrome diagnosis. Apolipoprotein B (ApoB) concentration reflects the number of LDL particles and is closely associated with atherosclerosis. The aim of this study was to compare the associations of ApoB, non-high-density lipoprotein cholesterol (NHDL-C), and low-density lipoprotein cholesterol (LDL-C) with metabolic syndrome and its relationship with significant coronary stenosis (SCS) in a Tunisian population. METHODS We enrolled 192 patients, who underwent coronary angiography. The body mass index, blood lipids, fasting glucose, insulin concentration, and blood pressure of every patient were measured. Metabolic syndrome was diagnosed according to the International Diabetes Federation criteria. RESULTS The frequency of metabolic syndrome was 58.3%. The comparison of the lipidic parameters between subject with and without metabolic syndrome showed a significant increase in ApoB and NHDL-C but not in LDL-C. By considering triglyceride (TG) limits (TG ≤ 0.9 mmol/L and TG > 1.70 mmol/L), we noted no differences in ApoB, NHDL-C, and LDL-C between subjects with and without metabolic syndrome in triglyceridemia ≤0.9 mmol/L. In triglyceridemia >1.70 mmol/L, a significant increase in ApoB and NHDL-C, but not in LDL-C, was noted. These results seem to consolidate the probability of increased sd-LDL in hypertriglyceridemic metabolic syndrome subjects. Indeed, in our study the odds ratio (OR) of SCS associated with metabolic syndrome is 3.81 (P = 0.007) in the studied population. This risk increases to 8.70 (P = 0.026) in hypertriglyceridemic subjects and seems to be associated with ApoB and NHDL-C (OR = 1.87, P = 0.038; OR = 1.26, P = 0.048). CONCLUSIONS This study suggests that ApoB and NHDL-C seem to be more correlated to SCS in metabolic syndrome with hypertriglyceridemia than LDL-C.
