ABSTRACT: Background
Apolipoproteins (Apo) are known atherogenic factors that play important roles in many mechanisms related to coronary heart disease (CHD). However, it is unclear whether the apoB/apoA1 ratio is an equal or a better predictor than the Framingham Risk Score or TC/HDL-c for predicting clinical outcomes in patients undergoing percutaneous coronary intervention.Methods
We investigated the association between Apolipoprotein B/A1 ratio and cardiovascular risk factors as well as the severity of CHD in 2256 Han Chinese patients. The potential of Apolipoprotein B/A1 ratio, Framingham Risk Score and TC/HDL-c were assessed as a marker to predict cardiovascular adverse events in a prospective subgroup of 1639 CHD patients during a 5-year follow-up.Results
In the multivariate model, adjusted odds ratios (ORs) were significant for 3-VD vs. 1-VD (OR = 2.36; 95% CI: 1.65-3.38, for the fourth vs. first quartile; Ptrend < 0.001). The subgroup analysis showed that patients with a higher ApoB/ApoA1 ratio had an increased risk of developing multi-branch lesions and potentially suffer more cardiovascular adverse events (anginas, myocardial infarctions, heart failures, strokes, and cardiac deaths) in the future (adjusted HR =1.92; 95% CI: 1.10-3.13, for the fourth vs. first quartile). In the ROC analysis, the AUC for ApoB/A1 ratio was larger than that of Framingham Risk Score (0.604 vs. 0.543, p = 0.01) and TC/HDL-c (0.604 vs. 0.525, p < 0.01).Conclusion
Our results suggest a significant association between ApoB/ApoA1 ratio and CHD severity and cardiovascular outcomes among patients with existing CHD and ApoB/A1 ratio demonstrated a better predictive accuracy for clinical outcomes compared with Framingham Risk Score and TC/HDL-c.

Project description:Background and aimsThe Apo B/A1 ratio is a major factor that predicts future cardiovascular outcomes. However, it is unclear whether the apolipoprotein B (Apo B)/apolipoprotein A1 (Apo A1) is a better predictor of future outcome than the total cholesterol (TC)/HDL-C ratio or lipoprotein (a) (Lp (a)) after the percutaneous coronary intervention (PCI). Therefore, we performed this study to evaluate the impact of the Apo B/A1 ratio on the patients who achieved LDL-C below 70 mg/dL one year after PCI.MethodsWe included 448 PCI patients whose LDL-C levels were below 70 mg/dL at follow-up. The Apo B/A1 ratio, TC/HDL-C ratio, and Lp (a) levels were measured at the time of PCI and follow-up, and decreases in these parameters between baseline and follow-up were assessed as potential markers to predict major cardiovascular adverse events (MACEs).ResultsDuring a median follow-up period of 38.0 months, 115 MACEs were recorded. The tertile with the lowest decrease in the Apo B/A1 ratio (≤ 0.146) showed a lower MACE survival rate compared to the other tertiles. There were no differences in MACE survival rates for the TC/HDL-C ratio or Lp (a) levels.ConclusionsThe Apo B/A1 ratio had better predictive accuracy for clinical outcomes compared to the TC/HDL-C ratio and Lp (a) level. A lower decrease in the Apo B/A1 ratio may be a residual risk factor for MACEs in patients who have reached LDL-C levels below 70 mg/dL after PCI.

Project description:Background and aimsThe apolipoprotein B (apoB)/apolipoprotein A1 (apoA1) ratio is a key indicator in predicting future cardiovascular outcomes. However, it is still unclear whether the ratio of apoB/apoA1 is a better predictor of the outcomes after intracerebral hemorrhage (ICH). Therefore, we aimed to assess the relationships between the ratio of apoB/apoA1 and functional outcomes, all-cause mortality, and stroke recurrence in ICH patients.MethodsTwo hundred and sixteen Chinese ICH patients participated in this study from December 2018 to December 2019. Laboratory routine tests including hematology analysis, coagulation tests, and lipid levels were examined. The clinical outcomes included functional outcomes evaluated by the modified Rankin Scale score (mRS), all-cause death, and stroke recurrence 1 year after discharge. Associations between the apoB/apoA1 ratio and the outcomes were evaluated using logistic regression analysis. Based on multivariate analysis, we constructed a nomogram. Univariate survival analysis was performed by the Kaplan-Meier method and log-rank test. All the patients were classified into two groups by the median value of the apoB/apoA1 ratio: B1 < 0.8 and B2 ≥ 0.8.ResultsOf the 216 patients, 107 had an apoB/apoA1 ratio ≥ 0.8. Eighty-five patients had poor functional outcomes (mRS ≥ 3), and 32 patients had severe functional outcomes (mRS ≥ 4). During the 1-year follow-up, a total of 18 patients died, and 13 patients had apoB/apoA1 ratio levels ≥0.8 during the 1-year follow-up period. Moreover, 16 recurrent strokes were recorded. Adjustments for age, sex, smoking, alcohol, body mass index, lipid levels, and hematoma site and volume showed that a high apoB/apoA1 ratio was significantly related to adverse functional outcomes and all-cause mortality. The ORs for B2 versus B1 were 3.76 (95% CI: 1.37 to 10.40, p = 0.010), 22.74 (95% CI: 1.08 to 474.65, p = 0.044), and 7.23 (95% CI: 1.28 to 40.88, p = 0.025) for poor functional outcomes with mRS ≥ 3, mRS ≥ 4, and all-cause mortality, respectively.ConclusionAn increased apoB/apoA1 ratio at admission was independently related to poor functional outcome and all-cause mortality in ICH patients at the 1-year follow-up.

Project description:The ratio of ApoB/apolipoprotein A1 (ApoA1) has been found to be associated with type 2 diabetes, and it was proposed as a new biomarker for type 2 diabetes predictions. Previous studies have assumed that the association between apoB/apoA1 and type 2 diabetes was linear. However, the linearity assumption has rarely been examined. In the present study, we aimed to examine whether this association showed a linear trend in a nationally representative population.Participants aged 18 years and over (n?=?8220) were selected from the China Health Nutrition Survey (CHNS). We used restricted cubic spline to model the association between ApoB/ApoA1 ratio and type 2 diabetes using logistic regression models. Additionally, we categorized the ApoB/ApoA1 ratio according to quartiles to compare with previous results. Age, gender, education, smoking status, high sensitivity C-reactive protein (hsCRP), lipid, body mass index (BMI), and hypertension were controlled as potential confounders.We found that the association between apoB/apoA1 ratio and type 2 diabetes may be nonlinear after adjusting for multiple potential confounders. Compared with the lowest quartile of apoB/apoA1 ratio, participants in the fourth quartile had a higher odds of type 2 diabetes [odds ratio (OR)?=?1.35, 95% confidence interval (CI)?=?1.01-1.81].Our results suggest that, higher apoB/apoA1 ratio was associated with higher prevalence of type 2 diabetes. However, the association may be nonlinear.

Project description:BackgroundThe ratio of nonhigh-density lipoprotein cholesterol (non-HDL-C) to high-density lipoprotein cholesterol (HDL-C) has been shown associated with various metabolic diseases and atherosclerosis in primary prevention. However, there is limited evidence on the relationship between the non-HDL-C/HDL-C ratio and progression of nonculprit coronary lesion (NCCL) after percutaneous coronary intervention (PCI).HypothesisOur study aimed to investigate the potential association between the non-HDL-C/HDL-C ratio and NCCL progression in patients with acute coronary syndrome (ACS) undergoing PCI.MethodsWe conducted a retrospective analysis of ACS patients who underwent coronary angiography twice at a single center from 2016 to 2022. Lipid measurements, demographic, clinical, and other laboratory data were collected from electronic medical records. NCCLs were evaluated using quantitative coronary angiography. The primary outcome was the progression of NCCL. Patients were categorized based on NCCL progression and tertiles of the non-HDL-C/HDL-C ratio. Associations were analyzed using univariate and multivariate logistic regression analysis.ResultsThe study included 329 ACS patients who underwent PCI, with a median follow-up angiography of 1.09 years. We found NCCL progression in 95 (28.9%) patients with acceptable low-density lipoprotein cholesterol control (median: 1.81 mmol/L). Patients in the top tertile of the non-HDL-C/HDL-C ratio had a higher risk of NCCL progression. After adjusting for potential confounding factors, the non-HDL-C/HDL-C ratio remained a significant predictor for NCCL progression (adjusted odds ratio: 1.45; 95% confidence interval: 1.14-1.86; p < 0.05).ConclusionsThe non-HDL-C/HDL-C ratio predicts NCCL progression in ACS patients following PCI, providing a valuable tool for risk assessment and enhancing secondary prevention of atherosclerotic cardiovascular disease.

Project description:Early identification of severe acute pancreatitis (SAP) is critical for clinical decision-making. The apolipoprotein B-to-apolipoprotein A1 ratio (ApoB/A1 ratio) reflects the balance between pro-inflammation and anti-inflammation in vivo. This study investigated the association between serum ApoB/A1 ratio at admission and acute pancreatitis (AP) severity. A total of 375 patients with first attack of AP were retrospectively recruited from January 2014 to December 2017. The severity of AP was assessed at admission based on the 2012 revised Atlanta Classification. Serum lipids levels were tested on the first 24 h of hospitalization, of which the correlations with clinical features or scoring systems were also measured. The ApoB/A1 ratio markedly increased across disease severity of AP. The ApoB/A1 ratio, expressed as both quartile and continuous variables, was significantly associated with a high risk of SAP, even after adjustment for other conventional SAP risk factors. The ApoB/A1 ratio positively correlated with the revised 2012 Atlanta Classification, Ranson score, Bedside Index for Severity in AP score, Modified Computed Tomography Severity Index score, and Acute Physiology and Chronic Health Evaluation II score for AP severity. The optimal cut-off value of ApoB/A1 ratio for detecting SAP was 0.88, with a sensitivity of 83.08% and a specificity of 69.03%. Serum ApoB/A1 ratio at admission is closely correlated with disease severity in patients with AP and can serve as a reliable indicator for SAP in clinical setting.

Project description:BACKGROUND:Dyslipidemia plays a significant role in the progression of cardiovascular disease. The apolipoprotein (apo) A1 remnant ratio (apo A1/VLDL3-C?+?IDL-C) has recently been shown to be a strong predictor of death/myocardial infarction risk among women >50 years undergoing angiography. However, whether this ratio is associated with coronary heart disease risk among other populations is unknown. We evaluated the apo A1 remnant ratio and its components for coronary heart disease incidence. DESIGN:Observational. METHODS:Participants (N?=?4722) of the Jackson Heart Study were evaluated. Baseline clinical characteristics and lipoprotein subfractions (Vertical Auto Profile method) were collected. Cox hazard regression analysis, adjusted by standard cardiovascular risk factors, was utilized to determine associations of lipoproteins with coronary heart disease. RESULTS:Those with new-onset coronary heart disease were older, diabetic, smokers, had less education, used more lipid-lowering medication, and had a more atherogenic lipoprotein profile. After adjustment, the apo A1 remnant ratio (hazard ratio?=?0.67 per 1-SD, p?=?0.002) was strongly associated with coronary heart disease incidence. This association appears to be driven by the IDL-C denominator (hazard ratio?=?1.23 per 1-SD, p?=?0.007). Remnants (hazard ratio?=?1.21 per 1-SD, p?=?0.017), but not apo A1 (hazard ratio?=?0.85 per 1-SD, p?=?0.121) or VLDL3-C (hazard ratio?=?1.13 per 1-SD, p?=?0.120) were associated with coronary heart disease. Standard lipids were not associated with coronary heart disease incidence. CONCLUSION:We found the apo A1 remnant ratio to be strongly associated with coronary heart disease. This ratio appears to better stratify risk than standard lipids, apo A1, and remnants among a primary prevention cohort of African Americans. Its utility requires further study as a lipoprotein management target for risk reduction.

Project description:Individuals with features of metabolic syndrome are particularly susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus associated with the severe respiratory disease, coronavirus disease 2019 (COVID-19). Despite considerable attention dedicated to COVID-19, the link between metabolic syndrome and SARS-CoV-2 infection remains unclear. Using data from the UK Biobank, we investigated the relationship between severity of COVID-19 and metabolic syndrome-related serum biomarkers measured prior to SARS-CoV-2 infection. Logistic regression analyses were used to test biomarker levels and biomarker-associated genetic variants with SARS-CoV-2-related outcomes. Among SARS-CoV-2-positive cases and negative controls, a 10 mg/dl increase in serum HDL-cholesterol or apolipoprotein A1 levels was associated with ∼10% reduced risk of SARS-CoV-2 infection, after adjustment for age, sex, obesity, hypertension, type 2 diabetes, and coronary artery disease. Evaluation of known genetic variants for HDL-cholesterol revealed that individuals homozygous for apolipoprotein E4 alleles had ∼2- to 3-fold higher risk of SARS-CoV-2 infection or mortality from COVID-19 compared with apolipoprotein E3 homozygotes, even after adjustment for HDL-cholesterol levels. However, cumulative effects of all evaluated HDL-cholesterol-raising alleles and Mendelian randomization analyses did not reveal association of genetically higher HDL-cholesterol levels with decreased risk of SARS-CoV-2 infection. These results implicate serum HDL-cholesterol and apolipoprotein A1 levels measured prior to SAR-CoV-2 exposure as clinical risk factors for severe COVID-19 infection but do not provide evidence that genetically elevated HDL-cholesterol levels are associated with SAR-CoV-2 infection.

Project description:PurposeThe purpose of this study was to investigate the predictive capability of neutrophil-to-apolipoprotein A1 ratio (NAR) for predicting overall survival (OS) among patients with hepatocellular carcinoma (HCC) receiving transarterial chemoembolization (TACE).Patients and methodsWe investigated the clinical features of 554 patients with HCC receiving TACE and assessed NAR's predictive value for OS with 222 patients (the discovery cohort) and 332 patients (the validation cohort). The association of NAR with circulation lectin-type oxidized low-density lipoprotein receptor-1-positive (LOX-1+ ) polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs) was illustrated.ResultsMultivariate Cox regression revealed that lymphocyte count; Tumor, Node, Metastasis (TNM) stage; and NAR were independent prognostic factors in the discovery cohort. The validation cohort confirmed the independent prognostic value of TNM stage and NAR. Patients with low NAR (<2.7) displayed significantly increased OS in the discovery cohort (59.8 months vs. 21 months), the validation group (38.0 months vs. 23.6 months), and the total cohort (44.1 months vs. 22.0 months). A Cox proportional hazards model was used to combine Cancer of the Liver Italian Program (CLIP) score with discretized NAR. C-index illustrated that NAR-integrated CLIP score was the best model compared with NAR and CLIP score. Furthermore, NAR-CLIP presented superior predictive capacity for 10-, 20-, 30-, 40-, 50-, and 60-month survival compared with CLIP score by survival receiver-operator characteristic analysis in the discovery cohort, validation cohort, and total cohort. NAR was significantly associated with LOX-1+ PMN-MDSCs by linear regression.ConclusionThis study identified NAR as an independent predictor for OS among patients with HCC receiving TACE. NAR reflected circulation LOX-1+ PMN-MDSC level.Implications for practiceThe present study identified neutrophil-to-apolipoprotein A1 ratio (NAR) as an independent predictor for overall survival among patients with hepatocellular carcinoma receiving transarterial chemoembolization. NAR reflected circulation level of lectin-type oxidized low-density lipoprotein receptor-1-positive polymorphonuclear myeloid-derived suppressor cells.

Project description:BackgroundCardiovascular disease is a leading cause of mortality in patients with juvenile-onset systemic lupus erythematosus (JSLE). Traditional factors for cardiovascular risk (CVR) prediction are less robust in younger patients. More reliable CVR biomarkers are needed for JSLE patient stratification and to identify therapeutic approaches to reduce cardiovascular morbidity and mortality in JSLE.MethodsSerum metabolomic analysis (including >200 lipoprotein measures) was performed on a discovery (n=31, median age 19) and validation (n=31, median age 19) cohort of JSLE patients. Data was analysed using cluster, receiver operating characteristic analysis and logistic regression. RNA-sequencing assessed gene expression in matched patient samples.FindingsHierarchical clustering of lipoprotein measures identified and validated two unique JSLE groups. Group-1 had an atherogenic and Group-2 had an atheroprotective lipoprotien profile. Apolipoprotein(Apo)B:ApoA1 distinguished the two groups with high specificity (96.2%) and sensitivity (96.7%). JSLE patients with high ApoB:ApoA1 ratio had increased CD8+ T-cell frequencies and a CD8+ T-cell transcriptomic profile enriched in genes associated with atherogenic processes including interferon signaling. These metabolic and immune signatures overlapped statistically significantly with lipid biomarkers associated with sub-clinical atherosclerosis in adult SLE patients and with genes overexpressed in T-cells from human atherosclerotic plaque respectively. Finally, baseline ApoB:ApoA1 ratio correlated positively with SLE disease activity index (r=0.43, p=0.0009) and negatively with Lupus Low Disease Activity State (r=-0.43, p=0.0009) over 5-year follow-up.InterpretationMulti-omic analysis identified high ApoB:ApoA1 as a potential biomarker of increased cardiometabolic risk and worse clinical outcomes in JSLE. ApoB:ApoA1 could help identify patients that require increased disease monitoring, lipid modification or lifestyle changes.FundingLupus UK, The Rosetrees Trust, British Heart Foundation, UCL & Birkbeck MRC Doctoral Training Programme and Versus Arthritis.

Project description:The neutrophil to apolipoprotein A1 ratio has emerged as a possible prognostic biomarker in different medical conditions. Nonetheless, the predictive potential of neutrophil to apolipoprotein A1 ratio in determining the 3-month prognosis of acute ischaemic stroke patients who undergo intravenous thrombolysis has yet to be fully acknowledged. In this study, 196 acute ischaemic stroke patients with recombinant tissue plasminogen activator and 133 healthy controls were included. Meanwhile, we incorporated a total of 386 non-thrombolytic acute ischaemic stroke patients. The acute ischaemic stroke patients with recombinant tissue plasminogen activator were divided into four groups based on quartiles of neutrophil to apolipoprotein A1 ratio. The association between neutrophil to apolipoprotein A1 ratio and the 3-month prognosis was evaluated through univariate and multivariate regression analyses. Additionally, subgroup analyses were conducted to investigate the predictive value of neutrophil to apolipoprotein A1 ratio in different patient populations. Adverse outcomes were defined as a modified Rankin Scale score of 3-6. The study findings revealed a significant association between elevated neutrophil to apolipoprotein A1 ratio levels and poor prognosis in acute ischaemic stroke patients. In the highest quartile of neutrophil to apolipoprotein A1 ratio levels (Q4), after controlling for age, gender, admission National Institutes of Health Stroke Scale score, blood urea nitrogen and stroke subtypes, the odds ratio for adverse outcomes at 3 months was 13.314 (95% confidence interval: 2.878-61.596, P = 0.001). An elevated neutrophil to apolipoprotein A1 ratio value was found to be associated with a poor prognosis in acute ischaemic stroke patients, regardless of whether they received recombinant tissue plasminogen activator treatment or not. The new model, which incorporating neutrophil to apolipoprotein A1 ratio into the conventional model, demonstrated a statistically significant improvement in discriminatory power and risk reclassification for 3-month poor outcomes in acute ischaemic stroke patients treated with recombinant tissue plasminogen activator. The new model exhibited a categorical net reclassification index (P = 0.035) of 12.9% and an integrated discrimination improvement (P = 0.013) of 5.2%. Subgroup analyses indicated that the predictive value of neutrophil to apolipoprotein A1 ratio differed across stroke subtypes. Neutrophil to apolipoprotein A1 ratio is a potential biomarker for predicting the prognosis of acute ischaemic stroke patients. The clinical implications of our findings are significant, as early identification and intervention in high-risk patients can improve their outcomes. However, further studies are required to validate our results and elucidate the underlying mechanisms of the association between neutrophil to apolipoprotein A1 ratio and poor prognosis in acute ischaemic stroke patients.
