Wu P. Association between polycyclic aromatic hydrocarbons exposure with red cell width distribution and ischemic heart disease: insights from a population-based study. Sci Rep 2024; 14:196. [PMID: 38168482 PMCID: PMC10762247 DOI: 10.1038/s41598-023-50794-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Accepted: 12/26/2023] [Indexed: 01/05/2024] Open
Abstract
This study investigates the association between polycyclic aromatic hydrocarbon (PAH) exposure, red blood cell distribution width (RDW), and ischemic heart disease (IHD) in a sample of 3003 participants from the National Health and Nutrition Examination Survey (NHANES). We hypothesize that RDW may mediate the effect of hydroxylated PAHs (OH-PAH) on IHD. Logistic regression models reveal significant associations between increased urinary PAH metabolite concentrations and IHD, as well as positive associations between PAH metabolites and RDW. Weighted Quantile Sum (WQS) regression and Bayesian Kernel Machine Regression (BKMR) analyses confirm the significant associations of the OH-PAH mixture with IHD and RDW. Mediation analysis demonstrates that RDW partially mediates the relationship between PAH exposure and IHD, accounting for 2-4.6% of the total effects. Our findings highlight the potential underlying mechanisms linking PAH exposure, RDW, and IHD and emphasize the importance of addressing environmental pollutants like PAHs in maintaining cardiovascular health and informing public health policies.

Abstract
IntroductionThe aim of this study was to develop a noninvasive prediction model for histological stages in PBC that is simple, easy to implement, and highly accurate.MethodsA total of 114 patients with PBC were included in this study. Demographic, laboratory data and histological assessments were collected. The independent predictors of histological stages were selected to establish a noninvasive serological model. The scores of 22 noninvasive models were calculated and compared with the established model.ResultsThis study included 99 females (86.8%) and 15 males (13.2%). The number of patients in Scheuer’s stage 1, 2, 3 and 4 was 33 (29.0%), 34 (29.8%), 16 (14.0%), and 31 (27.2%), respectively. TBA and RDW are independent predictors of PBC histological stages. The above indexes were used to establish a noninvasive model-TR score. When predicting early histological change (S1) or liver fibrosis and cirrhosis (S3-S4), the AUROC of TR score were 0.887 (95% CI, 0.809-0.965) and 0.893 (95% CI, 0.816-0.969), higher than all of the other 22 models included in this study. When predicting cirrhosis (S4), its AUROC is still as high as 0.921 (95% CI, 0.837-1.000).ConclusionTR score is an easy, cheap and stable noninvasive model, without complex calculation formulas and tools, and shows good accuracy in diagnosing the histological stages of PBC.

Association of Red Blood Cell Distribution Width and Neutrophil-to-Lymphocyte Ratio with Calcification and Cardiovascular Markers in Chronic Kidney Disease. Metabolites 2023; 13:metabo13020303. [PMID: 36837922 PMCID: PMC9966770 DOI: 10.3390/metabo13020303] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 02/10/2023] [Accepted: 02/16/2023] [Indexed: 02/22/2023] Open
Abstract
We aimed to investigate the association between Red Blood Cell Distribution Width (RDW) and Neutrophil-to-Lymphocyte Ratio (NLR), simple, rapidly assessed markers from the complete blood count with vascular calcification (VC)/stiffness and cardiovascular disease (CVD) in chronic kidney disease (CKD). Dephosphorylated, uncarboxylated matrix Gla-protein (dp-ucMGP), and central/peripheral hemodynamics' parameters were measured in 158 CKD patients, including Hemodialysis and Peritoneal Dialysis. Spearman's rho analysis showed that RDW correlated with C-reactive protein (CRP) (r = 0.29, p < 0.001), dp-ucMGP (r = 0.43, p = < 0.0001), central diastolic blood pressure (DBP) (r = -0.19, p = 0.02), and albuminuria (r = -0.17, p = 0.03). NLR correlated with the duration of CVD (r = 0.32, p < 0.001), CRP (r = 0.27, p = 0.01), dp-ucMGP (r = 0.43, p < 0.0001), central DBP (r = -0.32, p < 0.0001) and eGFR (r = -0.25, p = 0.04). In multiple regression models, circulating dp-ucMGP was an independent predictor of RDW (β = 0.001, p = 0.001) and NLR (β = 0.002, p = 0.002). In CKD patients, RDW and NLR are associated with traditional and novel markers of VC and CVD.

Sethi A, Melamud E. Joint inference of physiological network and survival analysis identifies factors associated with aging rate. CELL REPORTS METHODS 2022; 2:100356.

Abstract
We describe methodology for joint reconstruction of physiological-survival networks from observational data capable of identifying key survival-associated variables, inferring a minimal physiological network structure, and bridging this network to the Gompertzian survival layer. Using synthetic network structures, we show that the method is capable of identifying aging variables in cohorts as small as 5,000 participants. Applying the methodology to the observational human cohort, we find that interleukin-6, vascular calcification, and red-blood distribution width are strong predictors of baseline fitness. More important, we find that red blood cell counts, kidney function, and phosphate level are directly linked to the Gompertzian aging rate. Our model therefore enables discovery of processes directly linked to the aging rate of our species. We further show that this epidemiological framework can be applied as a causal inference engine to simulate the effects of interventions on physiology and longevity.

Computational Evidence for Laboratory Diagnostic Pathways: Extracting Predictive Analytes for Myocardial Ischemia from Routine Hospital Data. Diagnostics (Basel) 2022; 12:diagnostics12123148. [PMID: 36553154 PMCID: PMC9777462 DOI: 10.3390/diagnostics12123148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 10/24/2022] [Accepted: 10/29/2022] [Indexed: 12/15/2022] Open
Abstract
Background: Laboratory parameters are critical parts of many diagnostic pathways, mortality scores, patient follow-ups, and overall patient care, and should therefore have underlying standardized, evidence-based recommendations. Currently, laboratory parameters and their significance are treated differently depending on expert opinions, clinical environment, and varying hospital guidelines. In our study, we aimed to demonstrate the capability of a set of algorithms to identify predictive analytes for a specific diagnosis. As an illustration of our proposed methodology, we examined the analytes associated with myocardial ischemia; it was a well-researched diagnosis and provides a substrate for comparison. We intend to present a toolset that will boost the evolution of evidence-based laboratory diagnostics and, therefore, improve patient care. Methods: The data we used consisted of preexisting, anonymized recordings from the emergency ward involving all patient cases with a measured value for troponin T. We used multiple imputation technique, orthogonal data augmentation, and Bayesian Model Averaging to create predictive models for myocardial ischemia. Each model incorporated different analytes as cofactors. In examining these models further, we could then conclude the predictive importance of each analyte in question. Results: The used algorithms extracted troponin T as a highly predictive analyte for myocardial ischemia. As this is a known relationship, we saw the predictive importance of troponin T as a proof of concept, suggesting a functioning method. Additionally, we could demonstrate the algorithm's capabilities to extract known risk factors of myocardial ischemia from the data. Conclusion: In this pilot study, we chose an assembly of algorithms to analyze the value of analytes in predicting myocardial ischemia. By providing reliable correlations between the analytes and the diagnosis of myocardial ischemia, we demonstrated the possibilities to create unbiased computational-based guidelines for laboratory diagnostics by using computational power in today's era of digitalization.

Abstract
The effects of the oral glucose tolerance test (OGTT) on red blood cells (RBCs) have not been thoroughly investigated, although it is known that the ingestion of 75 g of glucose during OGTT results in a systemic state of inflammation and oxidative stress. Therefore, we evaluated the effect of OGTT on oxidative stress and L-arginine/Nitric Oxide (L-Arg/NO) metabolic pathway in RBCs obtained from patients with prediabetes. Blood samples were collected from all participants before (T0) and at 10 (T1), 20 (T2), 30 (T3), 60 (T4), 90 (T5), 120 (T6), 150 (T7), and 180 (T8) minutes after glucose loading. Results showed a significant increase in oxidative stress status characterized by a rise in the GSSG/GSH ratio at T4 and T6 that increased in parallel with a reduction of NO production in RBCs. In addition, in this time frame, increased exposure of phosphatidylserine on RBCs membrane was observed. These metabolic modifications were rescued at T8, together with an increase in activated RBC NO synthase expression. These findings provide a possible explanation of the phenomena occurring after glucose loading and suggest that, even in the early stages of diabetes, it may be important to avoid acute variations in glycemia in order to prevent diabetic complications.

Abstract
Background The hemoglobin level and red cell distribution width (RDW) have been linked to the prognosis of coronary atherosclerotic heart disease (CAHD). However, the relationship between the ratio of hemoglobin to the RDW (HRR) and clinical outcomes after percutaneous coronary intervention (PCI) is not known. Here, we explored the impact of the HRR on clinical outcomes after PCI. Methods In our study, we selected 6,046 CAHD patients with PCI hospitalized in the First Affiliated Hospital of Xinjiang Medical University from 2008 to 2016. The patients were grouped according to their HRR ratio: group A (HRR < 10.25, n = 2,344) and group B (HRR ≥ 10.25, n = 3,702). The difference in clinical outcomes between the two groups was compared. Patients were followed up for 35.9 ± 22.6 months. Results Three hundred nine patients died during follow-up. These included 166 patients (7.1%) in the HRR < 10.25 group and 143 patients (3.9%) in the HRR ≥ 10.25 group (P < 0.001). The incidences of cardiogenic death (5.7 vs. 3.2%) and major cardiovascular adverse events (16.5 vs. 12.9%) also differed significantly between the groups (both Ps < 0.001). Analysis using the multivariate Cox proportional hazard model found a significant association between a decreased HRR and post-PCI mortality (all-cause death, adjusted HR: 1.479, 95% CI: 1.156–1.893, p = 0.002; cardiac death, adjusted HR: 1.470, 95% CI: 1.116–1.936, p = 0.006). Conclusion The HRR is predictive of post-PCI mortality among CAHD patients.

Abstract
INTRODUCTION Glioblastoma (GBM) is the most common and deadly adult brain tumor. Red blood cell distribution width (RDW) has been found in non-central nervous system neoplasms to be associated with survival. This study aims to assess the prognostic value of pre-operative RDW and trends in RDW over time during the disease course. METHODS This single-institution retrospective cohort study identified patients ≥ 18 years old with pathology-proved glioblastoma treated between April 2003-May 2017 from an institutional database. A Cox proportional hazards model was developed using known prognostic clinical variables to predict overall survival time; a second model incorporating continuously valued RDW was then created. The additional prognostic value of RDW was assessed with a joint model F-test. The variation of RDW-CV over time was evaluated with linear mixed model of RDW. A post-hoc exploratory analysis was performed to assess the trend in RDW lab value leading up to time of death. RESULTS 346 adult GBM patients were identified; complete survival data was available for all patients. The addition of RDW to the multivariable Cox proportional hazards model did not increase prognostic value. There was an upward trend in RDW throughout the post-operative disease course. In a post-hoc analysis, there was an upward trend in RDW leading up to the time of death. CONCLUSION Although RDW has been prognostic of survival for many inflammatory, prothrombotic, and neoplastic diseases, pre-operative RDW was not associated with overall survival in GBM patients. RDW trended upwards throughout the disease course, suggesting possible systemic inflammatory effects of either glioblastoma or treatment.

Abstract
Background Inflammation plays a key role in the development of atherosclerosis and in the pathogenesis of acute coronary syndrome (ACS). Leukocytes and leukocytes ratios were recognized as inflammatory markers in predicting the presence and severity of ACS. Methods This study aimed to investigate the diagnostic accuracy of neutrophil to lymphocyte ratio (NLR) and monocyte to lymphocyte ratio (MLR) with ACS. One hundred patients admitted to the Cardiac Center who were confirmed to have ACS and 100 healthy controls confirmed not to have ACS were enrolled in this study. ECG and troponin I test were used as gold standards to make sure that the participants with or without ACS. Total white blood cells (WBCs) count, NLR, and MLR values were estimated.
Results Total WBCs, neutrophil, and monocyte counts were significantly higher while lymphocyte counts were significantly lower in ACS patients than in the healthy controls (p < 0.001). NLR and MLR were significantly higher in ACS patients than in the healthy controls (p < 0.001). Among all the studied markers, NLR was found to be the strongest predictive marker of ACS (OR: 3.3, p < 0.001), whereas MLR was non-significant (p > 0.05). A cut-off value of 2.9 of NLR had 90% sensitivity and 88% specificity while 0.375 cut-off value of MLR had 79% sensitivity, 91% specificity for predicting ACS presence. Conclusions NLR is a simple, widely available, and inexpensive inflammatory marker which can be an auxiliary biomarker in the diagnosis of ACS with a cut-off value of 2.9 in our population.

Abstract
OBJECTIVE Elevated red blood cell distribution width (RDW) level has been shown to be associated with poor outcomes in patients with cardiovascular disease. Limited data are available regarding the prognostic value of RDW in transcatheter aortic valve replacement (TAVR) patients. Therefore, we aimed to investigate the impact of RDW variation on outcomes of TAVR patients. METHODS From March 20, 2012, to February 20, 2020, the pre-TAVR RDW levels of 1,163 consecutive TAVR patients were examined. Receiver operating curves were set to define the most accurate cut-point, which was subsequently validated in our validation set. Associations of RDW levels with early and long-term outcomes were investigated. RESULTS A total of 988 patients were eligible for the analysis. Patients with 30-day, 1-year, and 7-year mortality had significantly higher pre-TAVR RDW levels (15.8% [12.9-19.1] vs 14.7% [11.6-26.3], P = 0.01; 16% [12.3-26.3] vs 14.7% [11.6-24.3], P < 0.001; 15.6% [12.3-26.3] vs 14.6% [11.6-24.3], P < 0.001, respectively). A RDW of 14.5% was found as the most sensitive and specific cut-point for mortality at 1 and 7 years (HR = 2.6, 95% CI: 1.6-4.2, P < 0.001; HR = 1.8, 95% CI: 1.3-2.4, P < 0.001), with mortality of 22% versus 10% at 1 year (P < 0.001) and 37% versus 27% at 7 years (P < 0.001) in patients with RDW ≥14.5% versus those with RDW <14.5%. CONCLUSIONS RDW is an important prognostic factor in TAVR patients. A RDW level higher than 14.5% is significantly associated with post-TAVR early and late mortality. RDW levels should be incorporated into current risk assessment models as an additional variable to predict post-TAVR outcomes.

RDW-based clinical score to predict long-term survival in community-acquired pneumonia: a European derivation and validation study. Intern Emerg Med 2021; 16:1547-1557. [PMID: 33428112 PMCID: PMC7797708 DOI: 10.1007/s11739-020-02615-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2020] [Accepted: 12/18/2020] [Indexed: 11/29/2022]
Abstract
An excess long-term mortality has been observed in patients who were discharged after a community-acquired pneumonia (CAP), even after adjusting for age and comorbidities. We aimed to derive and validate a clinical score to predict long-term mortality in patients with CAP discharged from a general ward. In this retrospective observational study, we derived a clinical risk score from 315 CAP patients discharged from the Internal Medicine ward of Cuneo Hospital, Italy, in 2015-2016 (derivation cohort), which was validated in a cohort of 276 patients discharged from the pneumology service of the Barakaldo Hospital, Spain, from 2015 to 2017, and from two internal medicine wards at the Turin University and Cuneo Hospital, Italy, in 2017. The main outcome was the 18-month follow-up all-cause death. Cox multivariate analysis was used to identify the predictive variables and develop the clinical risk score in the derivation cohort, which we applied in the validation cohort. In the derivation cohort (median age: 79 years, 54% males, median CURB-65 = 2), 18-month mortality was 32%, and 18% in the validation cohort (median age 76 years, 55% males, median CURB-65 = 2). Cox multivariate analysis identified the red blood cell distribution width (RDW), temperature, altered mental status, and Charlson Comorbidity Index as independent predictors. The derived score showed good discrimination (c-index 0.76, 95% CI 0.70-0.81; and 0.83, 95% CI 0.78-0.87, in the derivation and validation cohort, respectively), and calibration. We derived and validated a simple clinical score including RDW, to predict long-term mortality in patients discharged for CAP from a general ward.

Decrease in red cell distribution width as a useful predictor of success after catheter ablation for atrial fibrillation: a retrospective multi-center study. Heart Vessels 2021; 37:99-109. [PMID: 34374825 DOI: 10.1007/s00380-021-01891-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2021] [Accepted: 06/11/2021] [Indexed: 10/20/2022]
Abstract
Red cell distribution width (RDW) is reportedly associated with cardiovascular events, including atrial fibrillation (AF). We investigated whether the RDW values were associated with the outcomes of catheter ablation for AF. This retrospective multicenter study included 501 patients with AF (239 paroxysmal AF cases, 196 persistent AF cases, and 66 long-standing persistent AF cases) who underwent initial AF ablation between March 2017 and May 2018. The RDW values were evaluated before and at 1-3 months after the procedure. The patients were stratified based on the recurrence of AF within 1 year after the index procedure with a blanking period of 3 months into recurrence group (107 patients, 21.4%) and no-recurrence group (394 patients, 78.6%). There were no significant differences in preoperative RDW values between the groups (p = 0.37). The RDW value did not change significantly after the ablation in the recurrence group (13.55-13.60%, p = 0.37), although it decreased significantly in the no-recurrence group (13.64-13.37%, p < 0.001). Multivariate Cox proportional hazards regression analyses revealed that a postoperative change in RDW (ΔRDW) was independently associated with AF recurrence (hazard ratio 2.00, 95% confidence interval 1.42-2.76, p < 0.001). Receiver operating characteristic curve analysis revealed that a ΔRDW cut-off value of - 0.1% provided a c-statistic of 0.65 for predicting AF recurrence. Decrease in RDW during the blanking period after ablation independently predicted the 1-year success of AF ablation.

Simple Laboratory Test-Based Risk Scores in Coronary Catheterization: Development, Validation, and Comparison to Conventional Risk Factors. J Appl Lab Med 2021; 5:616-630.

Abstract
BACKGROUND We developed and validated laboratory test-based risk scores (i.e., lab risk scores) to reclassify mortality risk among patients undergoing their first coronary catheterization. METHODS Patients were catheterized between 2009 and 2015 in Calgary, Alberta, Canada (n = 14 135, derivation cohort), and in Edmonton, Alberta, Canada (n = 12 143, validation cohort). Logistic regression with group LASSO (least absolute shrinkage and selection operator) penalty was used to select quintiles of the last laboratory tests (red blood cell count, mean corpuscular hemoglobin concentration, mean corpuscular hemoglobin, mean corpuscular volume, red cell distribution width, platelet count, total white blood cell count, plasma sodium, potassium, chloride, CO2, international normalized ratio, estimated glomerular filtration rate) performed <30 days before catheterization and by age and sex that were significantly associated with death ≤60 and >60 days after catheterization. Follow-up was until 2016. Risk scores were developed from significant tests, internally validated in Calgary among bootstrap samples and externally validated in Edmonton after recalibration using coefficients developed in Calgary. Interaction tests were performed, and net reclassification improvement vs conventional demographic and clinical risk factors was determined. RESULTS Lab risk scores were strongly associated with mortality (29-40× for top vs bottom quintile, P for trends <0.01), had good discrimination and were well calibrated in Calgary (C = 0.80-0.85, slope = 0.99-1.01) and Edmonton (C = 0.80-0.82; slope = 1.02-1.05)-similar to demographic and clinical risk factors alone. Associations were attenuated by several comorbidities; however, scores appropriately reclassified 11%-20% of deaths (both follow-up periods) and 6%-9% of survivors (>60 days) after catheterization vs demographic and clinical risk factors. CONCLUSIONS In 2 populations of patients undergoing their first coronary catheterization, risk scores based on simple laboratory tests were as powerful as a combination of demographic and clinical risk factors in predicting mortality. Lab risk scores should be used for patients undergoing coronary catheterization.

Abstract
In this paper, by examining the toxicity of nano-silica to coronary heart disease cells, we explored the apoptosis of rat myocardial cells induced by nano-silica, and explored the effect of apoptosis on cells during the process of myocardial cytotoxicity induced by nano-silica. This article selects rat cardiomyocytes as the research object and conducts a group control experiment. A control group is set up with cells that are not stained with nano-silica. Different concentrations of nanosilica suspensions are applied to rat cells and detected by CCK-8 method. Cell survival rate after exposure to different concentrations of cells is used to determine the most stable exposure time and concentration. We used flow cytometry to detect intracellular reactive oxygen species and apoptotic rates, and used Western Blot to detect the expression of proteins that affect apoptosis. Finally, we investigated the effect of the Wnt signaling pathway on coronary heart disease. The Wnt signaling pathway regulates the development of the heart and blood vessels. In the treatment of cardiovascular disease, this pathway will be activated again to play a regulatory role. We conclude that nano-silica can induce cytotoxicity in rat myocardial cells through the Wnt-1 pathway, and nanosilica can induce myocardial cell apoptosis through the Wnt-1 pathway.

Abstract
The presence of left ventricular hypertrophy has been confirmed to be an independent risk factor for stroke and death in patients with atrial fibrillation. This retrospective study aimed to evaluate the potential risk factors for left ventricular hypertrophy in patients with atrial fibrillation.A series of consecutive patients diagnosed with atrial fibrillation between June 2018 and December 2019 were included. The patients' clinical data were analyzed. The cut-off values, sensitivity and specificity of the independent risk factors were calculated using a receiver operating characteristic curve.Among 87 patients with atrial fibrillation, 39 patients with left ventricular hypertrophy and 48 patients without left ventricular hypertrophy were included. Multivariate logistic regression analysis showed that red blood cell distribution width (odds ratio [OR] 4.89, 95% confidence interval [CI]: 1.69-14.13, P < .05) was an independent risk factor, while the concentration of low-density lipoprotein (OR 0.37, 95% CI: 0.17-0.83, P < .05) and left ventricular ejection fraction (OR 0.88, 95% CI: 0.82-0.95, P < .05) were inversely associated with left ventricular hypertrophy in atrial fibrillation patients. The receiver operating characteristic curve demonstrated that the area under the curve was 0.80 (95% CI: 0.71-0.90, P < .05) with a cut-off value of 13.05, and the red blood cell distribution width predicted left ventricular hypertrophy status among atrial fibrillation patients with a sensitivity of 72.1% and a specificity of 76.9%.Red blood cell distribution width was associated with left ventricular hypertrophy in patients with atrial fibrillation.

Abstract
Red blood cell distribution width (RDW) reflects erythrocyte size distribution, thus representing a reliable index of anisocytosis, widely used for the differential diagnosis of micro- and normocytic anaemias. Along with the large use in diagnostic hematology, RDW has been associated with presence and complications of a vast array of human pathologies during the last decades, including cardiovascular (CV) diseases. This article is hence aimed to provide an overview of important studies and systematic reviews with meta-analysis, in which RDW has been associated with CV events and mortality, in the attempt of establishing whether enough evidence exists for supporting its routine use in clinical practice. According to available data it seems reasonable to conclude that although the diagnostic specificity is low, and this measure is still plagued by important lack of standardization, RDW can be regarded as an index of enhanced patient fragility and higher vulnerability to adverse outcomes. Abnormal RDW values shall hence persuade physicians to broaden the diagnostic reasoning over anaemias, especially those due to malnutrition or malabsorption, encompassing a comprehensive assessment of traditional and non-traditional CV risk factors.

Abstract
Red cell distribution width (RDW) is an indirect marker of inflammation and an independent predictor of long-term mortality. The aim of this study was to determine RDW values in patients with ST-elevation acute myocardial infarction (STEMI) submitted to primary percutaneous coronary intervention (PCI) and evaluate its association with adverse outcomes. We measured RDW in STEMI patients before undergoing primary PCI and divided into low and high RDW. Patients were followed up to 3 years after their discharge for the occurrence of in-hospital, 30-days, and long-term major adverse cardiovascular events (MACEs) and mortality. We included 485 patients with a mean age of 61.1(±12.5) years, 62.9% were male. In multivariate analysis, RDW remained independent predictor of long-term mortality and MACE [relative risk (RR) 1.51; 95% confidence interval (95% CI) = 1.11-2.05; P = 0.007 and RR = 1.42; 95% CI = 1.30-1.82; P = 0.004. Area under the curve for long-term mortality was 0.65 (95% CI = 0.61-0.69; P < 0.0001). RDW < 13.4 had a negative predictive value of 87.4% for all-cause mortality. Patients who had worse outcomes remained with higher values of RDW during the follow-up. In conclusion, high RDW is an independent predictor of long-term mortality and MACE in patients with STEMI undergoing primary PCI. A low RDW has an excellent negative predictive value for long-term mortality. Patients with sustained elevated levels of RDW have worse outcomes at long-term follow-up.

Abstract
Red cell distribution width (RDW), one of the biomarkers used to measure vascular ageing, is known to correspond with cardiovascular diseases. As coronary artery disease and erectile dysfunction (ED) are both caused by the same shared pathophysiology, in this study, we compared the RDW values of men diagnosed with ED and those of healthy controls. Ninety-nine patients who were diagnosed with ED were included in the study. The control group consists of 100 men who presented to our outpatient clinic. Patients' fasting blood glucose, triglyceride, total cholesterol and LDL cholesterol levels were significantly higher in men diagnosed with ED. While the mean RDW value was 13.49 ± 1.52 in men with ED, it was 12.91 ± 1.13 in the control group. When RDW values were compared between the two groups, the RDW values of men with ED were found to be statistically significantly higher. Multivariate analyses showed that only the patients' body mass index, fasting blood sugar, triglyceride (TG), low-density lipoprotein cholesterol, high-density lipoprotein cholesterol levels (HDL-C), TG/HDL-C ratio and RDW levels' relationship with ED was statistically significant. Although some studies have shown that RDW may be related to some diseases such as cardiovascular diseases and cancer, this appears to be the first study demonstrating a relationship between RDW and ED. RDW can be utilised as a predictor for the determination of the presence and monitoring of the severity of ED.

Red blood cell distribution width as a prognostic factor in patients undergoing transcatheter aortic valve implantation. J Cardiol 2019; 74:212-216. [PMID: 31060955 DOI: 10.1016/j.jjcc.2019.04.005] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2018] [Revised: 03/12/2019] [Accepted: 04/09/2019] [Indexed: 12/17/2022]
Abstract
BACKGROUND Red blood cell distribution width (RDW), which is routinely reported in complete blood counts, is a measure of the variability in size of circulating erythrocytes. RDW is an independent predictor of prognosis in patients with cardiovascular diseases. We evaluated the short- and long-term prognostic value of RDW in a large cohort of transcatheter aortic valve implantation (TAVI) patients. METHODS The impact of RDW on outcome was determined prospectively in 1029 consecutive patients with severe aortic stenosis (AS) undergoing transfemoral TAVI. The cohort was divided into 2 groups according to RDW above and below 15.5%. Collected data included patient characteristics, medical background, left ventricle ejection fraction (LVEF), frailty score, Society of Thoracic Surgeons (STS) score, periprocedural laboratory results, and long-term (up to 7.5 years) clinical outcomes. RESULTS The mean age (±SD) was 83.1±6.3 years, mean STS score was 4.2±3.1% and mean estimated LVEF was 55.7±8.4%. Mean pre-TAVI RDW levels were 15.3±3.2%. Patients with RDW≤15.5% (n=683) and RDW>15.5% (n=346) had a 1-year mortality rate of 6% and 17%, respectively (p=0.001) and a 5-year mortality rate of 20% and 38%, respectively (p<0.001). Baseline RDW>15.5% was independently associated with all-cause mortality (hazard ratio 1.83, 95% confidence interval 1.44-2.32, p<0.001). CONCLUSIONS Elevated RDW is a strong independent marker and predictor of short- and long-term mortality following TAVI, that might present a relevant future supplement to current preprocedural risk scores. Additional research is needed to clarify the mechanisms responsible for this finding.

Elevated Red Blood Cell Distribution Width Is Associated with Morphometric Vertebral Fracture in Community-Dwelling Older Adults, Independent of Anemia, Inflammation, and Nutritional Status: The Korean Urban Rural Elderly (KURE) Study. Calcif Tissue Int 2019; 104:26-33.

Abstract
Elevated red blood cell distribution width (RDW), a simple measure of red blood cell size heterogeneity, has been associated with increased mortality and morbidity in the elderly population, which might reflect systemic inflammation and malnutrition. However, whether elevated RDW is associated with prevalent morphometric vertebral fracture (VF) in older adults has not been investigated. We examined 2127 individuals (mean age 71.7 years; women 66%) from a community-based cohort. VF was defined as ≥ 25% reduction in vertebral column height using the Genant semiquantitative method. Multiple VF was defined as the presence of VF at two or more sites. The prevalence of any VF and multiple VF was 14% and 4%, respectively, increasing from the lowest to the highest RDW tertiles (12-18% and 3-6%, p for trend < 0.05 for all). RDW was positively associated with age, body mass index (BMI), malnutrition, and high-sensitivity C-reactive protein (hsCRP), whereas it was negatively associated with albumin, hemoglobin, and ferritin levels. Elevated RDW was associated with any VF [adjusted odds ratio (aOR) 1.26; p = 0.008] and multiple VF (aOR 1.36; p = 0.010) after adjustment for covariates, including age, sex, BMI, hsCRP, malnutrition, self-reported previous fracture, falls, osteoporosis, and hemoglobin and ferritin levels. The association between elevated RDW and VF remained robust in subgroups with (aOR 1.39; p = 0.048) or without anemia (aOR 1.26; p = 0.030). Elevated RDW was associated with prevalent morphometric VF in community-dwelling elderly individuals, independent of anemia, inflammation, and nutritional status.

Abstract
BACKGROUND/OBJECTIVE Sleep apnea is associated with elevated inflammatory markers. A subgroup of patients never report sleep disturbances to their physician. The inflammatory status of this subgroup is not known. The present study aims to evaluate two inflammatory markers, C-reactive protein (CRP) and red cell distribution width (RDW), in those with unreported sleep disturbances and compares these findings to those with and without reported sleep disorders. We also investigate the utility of RDW as an inflammatory marker in sleep disorders. METHODS Sample includes 9,901 noninstitutionalized, civilian, nonpregnant adults from the 2005-2008 National Health and Nutrition Examination Survey, a nationally representative, cross-sectional U.S. study. Sleep questionnaire and laboratory data were used to compare inflammatory markers (CRP and RDW) in five subgroups of individuals: reporting physician-diagnosed sleep apnea, reporting another physician-diagnosed sleep disorder, reported sleep disturbance to physician with no resulting diagnosis, unreported sleep disturbance (poor sleep quality not reported to physician), and no diagnosed sleep disorder or sleep disturbance. RESULTS Individuals with unreported sleep disturbance had significantly higher odds of elevated RDW (>13.6%) when compared to those without a sleep disturbance in adjusted models (OR=1.33). Those with unreported sleep disturbance had significantly higher odds of elevated CRP levels (>1 mg/L) than those without sleep disturbances (OR 1.34), although the association was not significant when adjusted for obesity and other controls. CONCLUSION Self-identified unreported sleep disturbances are associated with significantly higher odds of elevated RDW than those without sleep disturbances. RDW may serve as a valuable indicator in identifying individuals at higher risk for sleep apnea and other sleep disorders.

Abstract
BACKGROUND Red cell distribution width (RDW) is a cardiac marker for risk stratification and prognostic evaluation of coronary artery disease (CAD); however, the underlying mechanism remains unclear. Erythropoietin (EPO), a crucial factor affecting erythropoiesis, has been reported to be a protective molecule regulating the process of myocardial ischemia and relevant damage. No study has as yet reported the relationship between RDW and endogenous EPO in CAD patients. This cross-sectional study aimed to establish the association between endogenous EPO levels and increases in RDW in CAD patients. PATIENTS AND METHODS Two hundred participants who underwent coronary arteriography were recruited from July 2015 to October 2015. The participants were divided into CAD and non-CAD groups on the basis of angiography diagnosis. Demographic data were obtained through personal interviews and general clinical methods. RESULTS RDW and EPO levels in the CAD group were higher than those in the non-CAD group. The correlation between RDW and EPO levels was statistically significant among CAD patients (r=0.411, P<0.001). The increases in EPO and RDW were related to the prevalence of CAD. The levels of RDW were correlated to endogenous EPO levels in CAD patients. CONCLUSION Increased EPO and RDW might be risk factors for CAD. Endogenous EPO levels are associated with increases in RDW in CAD patients.

Abstract
BACKGROUND The red cell distribution width (RDW) is associated with health outcomes. Whether non-RDW risk information is contained in RBC sizes is unknown. This study evaluated the association of the percentage of extreme macrocytic RBCs (%Macro, RBC volume > 120 fl) and microcytic RBCs (%Micro, RBC volume < 60 fl) and the RDW-size distribution (RDW-sd) with mortality and morbidity. METHODS Patients (females, n = 165,770; males, n = 100,210) at Intermountain Healthcare were studied if they had a hematology panel between May 2014 and September 2016. Adjusted sex-specific associations of %Macro/%Micro and RDW-sd with mortality and 33 morbidities were evaluated. RESULTS Among females with fourth-quartile values of %Macro quartile and %Micro (referred to throughout as 4/4), there was an average of 7.2 morbidities versus 2.9 in the lowest risk (LR1) categories, 1/1, 1/2, 2/1, and 2/2 (P < 0.001). Among males, those in the 4/4 category had 8.0 morbidities, while those in the LR1 had 3.4 (P < 0.001). Cox regressions found %Macro/%Micro (4/4 vs. LR1, females: hazard ratio [HR] = 1.97 [95% CI = 1.53, 2.54]; males: HR = 2.17 [CI = 1.72, 2.73]), RDW-sd (quartile 4 vs. 1, females: HR = 1.33 [CI = 1.04, 1.69]; males: HR = 1.41 [CI = 1.10, 1.80]), and RDW (quartile 4 vs. 1, females: HR = 1.59 [CI = 1.26, 2.00]; males: HR = 1.23 [CI = 0.99, 1.52]) independently predicted mortality. Limitations include that the observational design did not reveal causality and unknown confounders may be unmeasured. CONCLUSIONS Concomitantly elevated %Macro and %Micro predicted the highest mortality risk and the greatest number of morbidities, revealing predictive ability of RBC volume beyond what is measured clinically. Mechanistic investigations are needed to explain the biological basis of these observations.

Abstract
BACKGROUND Red blood cell distribution width (RDW) is a parameter of standard full blood count tests that reflects the size variability of erythrocytes In recent studies, RDW levels have been associated with ischemic heart disease, acute and chronic heart failure, hypertension, and inflammatory bowel disease. However, it is unclear whether RDW is associated with colorectal cancer. METHODS Eighty-five patients were diagnosed with colorectal cancer. Fifty-four other patients each diagnosed with colon polyps during the same period served as the control group. The patients were classified according to the seventh edition of the AJCC Cancer Staging Manual of 2009 into groups of different cancer stages, and simultaneously divided into groups with or without metastasis. The multigroup metering data was tested by a non-parametric Kruskal-Wallis H test, and the two subsets of patients formed above were compared using a Mann-Whitney U test. The association between continuous variables was assessed by Spearman correlation analysis while the association between RDW and colorectal cancer metastasis was estimated by receiver operating characteristic (ROC) curve analysis. RESULTS Increased RDW was observed in patients with colorectal cancer. The RDW was significantly different for each subgroup of colorectal cancer as follows: stage III + IV > stage III, T3 + T4 > T1 + T2, N1 + N2 > N0, and M1 > M0 (P < 0.05). The area under the receiver-operating characteristic curve of the RDW in the diagnosis of colorectal cancer metastasis was 0.721 (95% confidence interval of 0.612-0.831). CONCLUSIONS The value of RDW is closely related to colorectal cancer metastasis.

Abstract
The aim of this study was to examine the relationship between low-density lipoprotein cholesterol (LDL-C) and apolipoprotein (Apo) B levels and the SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery (SYNTAX) score (SS) in patients with stable angina pectoris. We enrolled 594 patients who were suspected to have coronary heart disease (CHD) and who underwent coronary angiography. Patients were divided into 4 groups based on the SS: normal (SS = 0, n = 154), low SS (SS ≤ 22, n = 210), intermediate SS (22 < SS < 32, n = 122), and high SS (SS ≥ 33, n = 63). Positive correlations between lipoprotein (a), LDL-C, ApoB, total cholesterol, and SS were significant ( r = 0.132, 0.632, 0.599, and 0.313, respectively; P < .01), whereas high-density lipoprotein cholesterol (HDL-C), ApoA1, and ApoA1/ApoB levels showed a significant negative correlation ( r = -0.29, -0.344, and -0.561, respectively; P < .01). Multivariate linear regression analysis revealed that LDL-C, ApoB, ApoA1/ApoB, fibrinogen (Fg), and HDL-C levels had an effect on SS (standardized regression coefficients were 0.41, 0.29, -0.12, 0.08, and -0.09, respectively; P < .05). In conclusion, LDL-C, ApoB, ApoA1/ApoB, Fg, and HDL-C levels affected the SS and were predictors of CHD complexity.

Abstract
SummaryRed blood cell distribution width (RDW) has been shown to predict cardiovascular mortality in various populations, but studies were less conclusive regarding cardiovascular morbidity. We aimed at evaluating the prognostic effect of RDW on cardiovascular morbidity and allcause mortality in the largest community cohort to date. We utilised the computerised database of a large community based healthcare maintenance organization (HMO) in Israel to identify a cohort of 225,006 eligible patients aged 40 or above who performed a blood count during 2006. We evaluated the relationship between 1% increments of RDW values and major cardiovascular events and all-cause mortality over a period of five years. A total of 21,939 incident cases of a major cardiovascular event and 4,287 deaths were documented during a total of six years of follow up, respectively. In comparison with patients with RDW level <13%, the hazard ratio for total mortality gradually increased to 4.57 (95% confidence interval [CI]: 3.35–6.24, p<0.001) among male patients and to 3.26 (95% CI: 2.49–4.28, p<0.001) among female patients with a RDW of 17% or above. Similar results were evident in anaemic and non-anaemic populations. RDW above 17% was also associated with a modest increased risk of major cardiovascular events in females 1.26 (95% CI: 1.03–1.52, p=0.021), while in men it was not significant, 1.08 (95% CI: 0.82–1.41, p=NS). In conclusion, increasing RDW levels significantly increased risk of cardiovascular morbidity and all-cause mortality. Our observation is evident in both anaemic and non-anaemic patients.

Abstract
SummaryRecent studies suggest an association between red cell distribution width (RDW) and incident venous thromboembolism (VTE). We aimed to investigate the impact of RDW on risk of incident and recurrent VTE, and case-fatality, in a general population. RDW was measured in 26,223 participants enrolled in the Tromsø Study in 1994–1995. Incident and recurrent VTE events and deaths during follow-up were registered until January 1, 2012. Multivariate Cox proportional hazards regression models were used to calculate hazard ratios (HR) with 95% confidence intervals (CI). There were 647 incident VTE events during a median of 16.8 years of follow-up. Individuals with RDW in the highest quartile (RDW≥13.3%) had 50% higher risk of an incident VTE than those in the lowest quartile (RDW≤12.3%). The association was strongest for unprovoked deep-vein thrombosis (HR highest vs lowest quartile of RDW: 1.8, 95% CI 1.1–3.1). VTE patients with baseline RDW≥13.3% had 30% higher risk of all-cause mortality after the initial VTE event than VTE patients with RDW<13.3%. There were no association between RDW and risk of recurrent VTE. Our findings suggest that high RDW is a risk factor of incident VTE, and that RDW is a predictor of all-cause mortality in VTE patients.

Red Cell Distribution Width Is Associated with All-Cause and Cardiovascular Mortality in Patients with Diabetes. BIOMED RESEARCH INTERNATIONAL 2017; 2017:5843702. [PMID: 29359154 PMCID: PMC5735623 DOI: 10.1155/2017/5843702] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/01/2017] [Accepted: 07/27/2017] [Indexed: 01/06/2023]
Abstract
Background and Methods Red cell distribution width (RDW) has emerged as a prognostic marker in patients with cardiovascular diseases. We investigated mortality in patients with diabetes included in the National Health and Nutrition Examination Survey, in relation to baseline RDW. RDW was divided into 4 quartiles (Q1: ≤12.4%, Q2: 12.5%–12.9%, Q3: 13.0%–13.7%, and Q4: >13.7%). Results A total of 3,061 patients were included: mean age 61 ± 14 years, 50% male, 39% White. Mean RDW was 13.2% ± 1.4%. Compared with first quartile (Q1) of RDW, patients in Q4 were more likely to be older, female, and African-American, have had history of stroke, myocardial infarction, and heart failure, and have chronic kidney disease. After a median follow-up of 6 years, 628 patient died (29% of cardiovascular disease). Compared with Q1, patients in Q4 were at increased risk for all-cause mortality (HR 3.44 [2.74–4.32], P < .001) and cardiovascular mortality (HR 3.34 [2.16–5.17], P < .001). After adjusting for 17 covariates, RDW in Q4 remained significantly associated with all-cause mortality (HR 2.39 [1.30–4.38], P = 0.005) and cardiovascular mortality (HR 1.99 [1.17–3.37], P = 0.011). Conclusion RDW is a powerful and an independent marker for prediction of all-cause mortality and cardiovascular mortality in patients with diabetes.

Abstract
AIMS To investigate the association between red cell distribution width (RDW) and elevation of glucose/glycated hemoglobin (HbA1c). METHODS An analysis was conducted using data from a prospective cohort study of adults. People without prediabetes or diabetes (n=7,795) were followed for a mean of 2.90years (range: 1-7years, 95% confidence interval: 2.86-2.94years). Glucose elevation is defined as fasting glucose levels exceeding 5.6mmol/l, or 2-hour glucose values in the oral glucose tolerance test exceeding 7.8mmol/l. HbA1c elevation is defined as a HbA1c value exceeding a normal limit of 39mmol/mol (5.7%). Adjusted Cox proportional hazards regression models were used to assess the association between RDW quartiles and elevation of HbA1c/glucose. RESULTS The multiple-adjusted hazard ratios (95% confidence interval) of HbA1c elevation for increased quartiles of RDW were 1.00 (reference), 1.08 (0.89, 1.30), 1.28 (1.07, 1.54), and 1.54 (1.29, 1.85) (P for trend<0.0001). However, no significant association was observed between RDW and blood glucose (fasting and postprandial). CONCLUSIONS Elevated RDW is independently related to future HbA1c elevation, but not to glucose elevation. This suggests that RDW may associate with HbA1c through a non-glycemic way, which should be taken into consideration when using HbA1c as a diagnostic criterion of prediabetes or diabetes.

Abstract
The red blood cell distribution width (RDW) obtained from a standard complete blood count (CBC) is a convenient and inexpensive biochemical parameter representing the variability in size of circulating erythrocytes. Over the past few decades, RDW with mean corpuscular volume (MCV) has been used to identify quite a few hematological system diseases including iron-deficiency anemia and bone marrow dysfunction. In recent years, many clinical studies have proved that the alterations of RDW levels may be associated with the incidence and prognosis in many cardiovascular and cerebrovascular diseases (CVDs). Therefore, early detection and intervention in time of these vascular diseases is critical for delaying their progression. RDW as a new predictive marker and an independent risk factor plays a significant role in assessing the severity and progression of CVDs. However, the mechanisms of the association between RDW and the prognosis of CVDs remain unclear. In this review, we will provide an overview of the representative literatures concerning hypothetical and potential epidemiological associations between RDW and CVDs and discuss the underlying mechanisms.

Abstract
Introduction Preoperative anemia and high red cell distribution width (RDW) are associated with higher perioperative mortality. Conditions with high RDW levels can be categorized by mean corpuscular volume (MCV). The relationship between RDW, anemia and MCV may explain causality between high RDW levels and outcomes. We aim to establish the prevalence of preoperative anemia and distribution of RDW and MCV among pre-surgical patients in Singapore. In addition, we aim to investigate the association between preoperative anemia, RDW and MCV levels with one-year mortality after surgery. Methods Retrospective review of 97,443 patients aged > = 18 years who underwent cardiac and non-cardiac surgeries under anesthesia between January 2012 and October 2016. Patient demographics, comorbidities, priority of surgery, surgical risk classification, perioperative transfusion, preoperative hemoglobin, RDW, MCV were collected. WHO anemia classification was used. High RDW was defined as >15.7%. Multivariate regression analyses were done to identify independent risk factors for mild or moderate/severe anemia and high RDW (>15.7). Multivariate cox regression analysis was done to determine the effect of preoperative anemia, abnormal RDW and MCV values on 1-year mortality. Results Our cohort comprised of 94.7% non-cardiac and 5.3% cardiac surgeries. 88.7% of patients achieved 1 year follow-up. Anemia prevalence was 27.8%—mild anemia 15.3%, moderate anemia 12.0% and severe anemia 0.5%. One-year mortality was 3.5%. Anemia increased with age in males, while in females, anemia was more prevalent between 18–49 years and > = 70 years. Most anemics were normocytic. Normocytosis and macrocytosis increased with age, while microcytosis decreased with age. Older age, male gender, higher ASA-PS score, anemia (mild- aHR 1.98; moderate/severe aHR 2.86), macrocytosis (aHR 1.47), high RDW (aHR 2.34), moderate-high risk surgery and emergency surgery were associated with higher hazard ratios of one-year mortality. Discussion Preoperative anemia is common. Anemia, macrocytosis and high RDW increases one year mortality.

Abstract
Red cell distribution width (RDW) is linked to cardiovascular risk in the general population, an association that might be driven by inflammation. Whether this relationship holds for patients with HIV infection has not been previously studied. Using a large clinical registry, we show that elevated RDW (>14.5%) is independently associated with increased risk of coronary artery disease {odds ratio [OR] 1.39 [95% confidence interval (CI): 1.25 to 1.55]}, peripheral vascular disease [OR 1.41 (95% CI: 1.29 to 1.53)], myocardial infarction [1.43 (95% CI: 1.25 to 1.63)], heart failure [OR 2.23 (95% CI: 1.99 to 2.49)], and atrial fibrillation [OR 1.96 (95% CI: 1.64 to 2.33)]. In conclusion, in the context of the inflammatory milieu that accompanies HIV infection, RDW remains a powerful marker of cardiovascular disease.

Abstract
Objective Coronary Artery Disease (CAD) is the leading cause of morbidity and mortality all around the world. We evaluated the correlation of Red blood cell Distribution Width (RDW) with the severity of lesion on coronary angiography as assessed by Modified Gensini score (MGS) in CAD patients. Methods A total of 576 consecutive patients admitted in Department of Cardiology over a period of one year, who underwent coronary angiography after diagnosis of CAD or presence of angina like chest pain and/or positive treadmill test were enrolled in the study (August 2014–May 2015). Patients were divided into two groups, with CAD (Group A) and without CAD (Group B). The RDW Cofficience of variance (RDW CV) and RDW standard deviatiton (RDW SD) of each patient, and their correlation with severity of CAD was assessed. Results Of the total 576 patients enrolled, 438 were in Group A and 138 were in Group B. The mean age of presentation in Group A and Group B was (53.64 ± 10.36 vs 49.4 ± 9.73) years (p < 0.0001). The Male and Female ratio overall was 2.42:1. Patients in Group A had significantly elevated RDW CV and RDW SD levels compared with those in Group B [(14.59 ± 1.04)% vs (13.6 ± 0.68)%, p < 0.0001], [(45.78 ± 4.76) vs (40.77 ± 3.01), p < 0.0001 respectively]. A significant positive correlation between RDW CV, RDW SD and MGS was noted (r = 0.33, p < 0.0001) (r = 0.43, p < 0.0001) respectively. On multivariate logistic regression analysis, RDW was demonstrated to be an independent predictor for angiographic CAD (OR = 4.17, 95% CI 3.05–5.69, p < 0.0001). On receiver operating characteristic curve (ROC) analysis, an RDW value of 14.3% was identified as an effective cut off point in diagnosing CAD with a sensitivity of 58.9% and specificity of 84.8%. Conclusions RDW is an independent predictor of CAD and severity of coronary stenosis, suggesting that it can be a readily available marker for prediction and severity of CAD.

Abstract
OBJECTIVES High values of Red Blood Cell Distribution Width (RDW) have been associated with adverse outcome in various clinical settings. The mechanism behind this association is not clear. The Metabolic Syndrome (MetS) is a chronic inflammatory disorder that increases the risk for cardiovascular disease and death. The aim of our study was to evaluate the association between high RDW and the MetS in a relatively large cohort of patients. METHODS A cohort of 3,529 consecutive patients undergoing coronary angiography was used to evaluate the association between RDW and the MetS. The association was assessed by using a logistic regression. Cox's regression analysis was used to evaluate the impact of RDW on long term mortality. RESULTS The mean age was 65 years (range 24-97), with 27% women. Overall, 30% were diagnosed with metabolic syndrome. The prevalence of MetS was 29% in patients with RDW <14% and 34% in patients with RDW ≥14% (P = 0.003).Using multivariate analysis, RDW values above 14% were independently associated with MetS (odds ratio 1.2 [95% CI 1.0-1.4], P = 0.043). Among all the criteria of the metabolic syndrome, hypertension, elevated glucose levels and abdominal obesity were associated with high RDW, with hypertension being the strongest criteria, with an increased risk of 1.8 fold ([95% CI 1.5-2.1]; P = 0.001). During follow up (1614 ± 709 days, 2-2763 days), long term mortality was 8% in the low RDW group and 28% in the high RDW group (p < 0.001). CONCLUSION RDW ≥14% is independently associated with higher rates of metabolic syndrome and long-term all-cause mortality.

Abstract
Stent thrombosis is a rare but potentially fatal complication of percutaneous coronary interventions (PCIs). In recent years, the predictive and prognostic value of the red cell distribution width (RDW) as an indicator of inflammation has been shown in many cardiovascular diseases. Aim of this study was to examine the predictive value of RDW for stent thrombosis in patients who underwent successful stent implantation for ST-elevation myocardial infarction (STEMI).In this retrospective study, 146 patients who underwent successful PCI to native coronary artery due to STEMI previously and presented with acute coronary syndrome with stent thrombosis were included (stent thrombosis group). A total of 175 patients who had similar procedural characteristics (type, diameter, and length of stent) and not had stent thrombosis were consisted control group.Patients were divided into tertiles according to the admission RDW values (12.9 ± 0.4, 14.2 ± 0.4, and 16.3 ± 1.5, respectively). Stent thrombosis developed in 47 (40.9%) patients in the lowest tertile, 39 (37.9%) patients in mid tertile, and 60 (58.3%) patients in the highest tertile (P = 0.006). Female gender ratio was statistically significantly higher in the 3rd tertile (13 [11.3%], 8 [7.8%], 24 [23.3%], P = 0.003, respectively). RDW (OR: 1.397 [95% CI 1.177-1.657], P < 0.001) and platelet count (OR: 1.008 [95% CI 1.004-1.012], P < 0.001) remained independent predictors of stent thrombosis after multivariate logistic regression analysis. ROC curve analysis demonstrated that, admission RDW values higher than 13.9 can predict the development of stent thrombosis with a sensitivity of 57% and a specificity of 52% (The area under the ROC curve: 0.59 [95% CI 0.53-0.65] P = 0.007).High RDW values found to be independently associated with the development of stent thrombosis in patients with STEMI.

Abstract
INTRODUCTION Red cell distribution width (RDW) has been linked to cardiovascular disease. We sought to determine whether addition of RDW improved the Framingham risk score (FRS) model to predict cardiovascular mortality in a healthy US cohort. METHODS We performed a post-hoc analysis of the National Health and Nutritional Examination Survey-III (1988-94) cohort, including non-anemic subjects aged 30-79years. Primary endpoint was death from coronary heart disease (CHD). We divided the cohort into three risk categories: <6%, 6-20% and >20%. RDW>14.5 was considered high. Kaplan-Meier survival curves and Cox proportional hazards models were created. Discrimination, calibration and reclassification were used to assess the value of addition of RDW to the FRS model. RESULTS We included 7005 subjects with a mean follow up of 14.1years. Overall, there were 233 (3.3%) CHD deaths; 27 (8.2%) in subjects with RDW>14.5 compared to 206 (3.1%) in subjects with RDW≤14.5 (p<0.001). Adjusted hazard ratio of RDW in predicting CHD mortality was 2.02 (1.04-3.94, p=0.039). Addition of RDW to FRS model showed significant improvement in C-statistic (0.8784 vs. 0.8751, p=0.032) and area under curve (0.8565 vs. 0.8544, p=0.05). There was significant reclassification of FRS with a net reclassification index (NRI) of 5.6% (p=0.017), and an intermediate-risk NRI of 9.6% (p=0.011). Absolute integrated discrimination index (IDI) was 0.004 (p=0.02), with relative IDI of 10.4%. CONCLUSIONS Our study demonstrates that RDW is a promising biomarker which improves prediction of cardiovascular mortality over and above traditional cardiovascular risk factors.

Abstract
Background Recently, accumulating evidence has demonstrated that RDW independently predicts clinically important outcomes in many populations. However, the role of RDW has not been elucidated in chronic kidney disease (CKD) patients. We conducted the present study with the aim to evaluate the predictive value of RDW in CKD patients. Methods A retrospective observational cohort study of 1075 stage 3–5 CKD patients was conducted in a medical center. The patients’ baseline information included demographic data, laboratory values, medications, and comorbid conditions. The upper limit of normal RDW value (14.9%) was used to divide the whole population. Multivariate Cox regression analysis was used to determine the independent predictors of mortality. Results Of the 1075 participants, 158 patients (14.7%) died over a mean follow-up of approximately 2.35 years. The crude mortality rate was significantly higher in the high RDW group (high RDW group, 22.4%; low RDW group 11%, p <0.001). From the adjusted model, the high RDW group was correlated with a hazard ratio of 2.19 for overall mortality as compared with the low RDW group (95% CI = 1.53–3.09, p<0.001). In addition, the high RDW group was also associated with an increased risk for cardiovascular disease (HR = 2.28, 95% CI = 1.14–4.25, p = 0.019) and infection (HR = 1.9, 95% CI = 1.15–3.14, p = 0.012)) related mortality in comparison with the low RDW group. Conclusions In stage 3–5 CKD patients, RDW was associated with patient mortality of all-cause, cardiovascular disease and infection. RDW should be considered as a clinical predictor for mortality when providing healthcare to CKD patients.

Abstract
Chronic total occlusion (CTO) is a common finding in 40% of the patients with peripheral arterial disease (PAD). The aim of this study was to investigate the determinants of CTO in patients with PAD. The study included a total of 211 nonanemic patients with PAD. All patients were categorized according to the Fontaine classification. In lower extremity angiography cohorts, CTO− patients were designated as group 1 and CTO+ patients were designated as group 2. Patients with CTO had significantly higher red cell distribution width (RDW), neutrophil–lymphocyte ratio, uric acid, and high-sensitivity C-reactive protein compared to patients without CTO ( P ≤ .001, P = .036, P ≤ .001, and P = .015, respectively). Albumin, total bilirubin, and direct bilirubin were significantly lower in the patients with CTO compared to patients without CTO ( P = .023, P ≤ .001, and P = .049, respectively). Multivariate logistic regression analysis showed that RDW, uric acid, and total bilirubin were independent predictors of CTO in patients with PAD. We demonstrated that increased RDW and uric acid levels and lower total bilirubin values were independently associated with CTO in patients with PAD.

Abstract
Background: The coronary slow-flow phenomenon (CSFP) is a multifactorial angiographic finding with no established pathogenesis. Objective: To investigate the role of clinical profile and laboratory findings in patients with CSFP. Methods: We prospectively recruited 69 patients with angiographically diagnosed CSFP and compared them with 88 patients with normal coronary flow. Demographic information, comorbidities and laboratory analysis, including complete blood count with differential, lipid profile and serum biochemical analysis, were documented and compared in univariate and multivariate analyses. Results: Patients with CSFP were more likely to be male and active smokers. Total cholesterol, triglyceride, hemoglobin and hematocrit, platelet count, mean platelet volume, platelet distribution width and red cell distribution width (RDW) were all higher in patients with CSFP. In multivariate regression analysis, including smoking, total cholesterol, hematocrit, fasting blood glucose and red cell distribution width, except fasting blood glucose, all variables were independently associated with CSFP. Receiver operating characteristic curve analysis revealed a cut-off point of 13.05% for RDW with a sensitivity of 74.6% and a specificity of 77.3% (p<0.001, AUC = 0.802) A cut-off value of 11.35% for PDW had a 89.9% sensitivity and 98.9% specificity for the prediction of CSFP (p<0.001, AUC = 0.970) Conclusion: The changes of circulating blood cell components in patients with CSFP may be indicative of underlying inflammation and endothelial dysfunction that should be investigated in experimental studies.

Abstract
INTRODUCTION Red cell distribution width (RDW) describes heterogeneity in the size of red blood cells. An increase in RDW has been associated with excess mortality in heart failure and other chronic diseases. Since there is an increased risk of cardiovascular morbidity and mortality in obstructive sleep apnea (OSA), it is possible that these patients have a high RDW. METHOD We recruited subjects aged 18 to 60 years referred to the sleep-disordered breathing unit for suspected OSA. Subjects with any comorbidity were excluded. Apnea-hypopnea index (AHI) was calculated from the respiratory polygraphy. The RDW was obtained from the complete blood count. Changes in RDW after one year of treatment with continuous positive airway pressure (CPAP) were determined. RESULTS We included 34 healthy subjects and 138 with OSA, aged 40.5±9.8 and 45.6±9.2 (P=.004) years, respectively. The RDW was higher in subjects with OSA compared to healthy subjects: 13.40 (12.40 to 14.40) vs. 13.15 (12.07 to 14.23) (P=.036). AHI showed a positive independent relationship with RDW in both the whole population (r=0.223; P=.002) and the OSA group (r=0.231; P=.005). No significant changes were found in RDW after one year of CPAP therapy. CONCLUSIONS RDW increase in patients with OSA is directly associated with severity, although levels are not modified by the effective treatment of OSA with CPAP.

Abstract
OBJECTIVES Red cell distribution width (RDW) and neutrophil-to-lymphocyte ratio (NLR) are the two markers used to determine risk of mortality and adverse cardiovascular outcomes in patients with acute myocardial infarction. The relationship between RDW, NLR, and left ventricular (LV) systolic functions has not been reported. In this report, we aimed to investigate the relationship between RDW, NLR, and LV systolic function in anterior ST-segment elevation myocardial infarction (STEMI) patients who underwent primary percutaneous coronary intervention (PCI). METHODS RDW and NLR were measured on admission in 106 STEMI patients treated with primary PCI. Patients were divided into two groups according to left ventricular ejection fraction (LVEF), as Group I (systolic dysfunction, LVEF <50%) and Group II (preserved global left ventricle systolic function, LVEF ⩾50%). The first group included 47 patients and the second group included 59 patients. RESULTS Mean RDW and NLR were significantly higher in Group I compared to Group II [13.7 ± 0.9% vs. 13.4 ± 0.7%, p = 0.03 and 5.86 (range, 0.66-40.50) vs. 2.75 (range, 0.51-39.39), p = 0.013, respectively]. CONCLUSION Increased RDW and NLR on admission, in anterior STEMI patients treated with primary PCI are associated with LV systolic dysfunction.

Abstract
INTRODUCTION The red cell distribution width (RDW) is a biomarker strongly associated with poor outcome in inflammatory and thrombotic diseases. Subarachnoid hemorrhage (SAH) is both an inflammatory and thrombotic state in which many biomarkers have been studied. In this exploratory pilot study, we sought to determine whether RDW predicts poor outcome in patients with SAH. METHODS Patients with moderate-to-severe SAH were prospectively enrolled in an observational study of biomarkers and outcome. CBC, ESR, high sensitivity CRP, D-dimer, and fibrinogen were obtained on post-bleed days (PBD) 1, 3, 5, 7, and 10. Poor outcome was defined as a modified Rankin score of 3-6 at 90-days. RESULTS Of 40 patients, 5 (12.5%) died and 19 (47.5%) had a poor outcome. RDW (p = 0.046) when measured serially over the study period, was significantly higher among patients with poor outcome. Maximum RDW (OR 2.3 95% CI 1.2-3.6; p = 0.014) and maximum WBC count (OR 1.29 95% CI 1.04-1.60; p = 0.018) were associated with poor outcome. Stepwise addition of maximum ESR, CRP, D-dimer, and fibrinogen yielded a model with RDW (OR 2.54 95% CI 1.21-5.35; p = 0.014) and fibrinogen (OR 1.01 95% CI 1.002-1.01; p = 0.004) predicting outcome. With addition of age and Hunt and Hess grade, RDW, fibrinogen, and high-grade status remained significantly associated with poor outcome. Use of PBD1 RDW in lieu of maximum RDW, resulted in a similar model. CONCLUSIONS An elevated RDW is associated with poor outcome in SAH patients. RDW may be a useful predictor of outcomes after SAH.

Abstract
OBJECTIVE Considering the limited studies specifically evaluating the role of Red blood cell distribution width (RDW) in primary percutaneous coronary intervention (PCI), we aimed to investigate the role of baseline RDW in short- and intermediate-term cardiovascular events in ST-elevation myocardial infarction patients under primary PCI. METHODS This is a historical cohort registry analysis of 1161 patients with ST-elevation myocardial infarction under primary PCI. According to inclusion criteria, 838 patients were allocated for analysis. Patients with RDW levels of 13.6% or higher were considered as high RDW group (third tertile). All the individuals were followed up for in-hospital and 6-month mortality along with readmission and composite major adverse cardiac events. RESULTS In-hospital deaths occurred in 53 (6.3%) patients and at 6-month follow-up 79 (9.4%) cases of mortality were documented. In-hospital and 6-month mortalities showed a significant trend in favor of high RDW group (13.3% vs. 5.9%, P = 0.003; 19.7% vs. 7.9%, P < 0.001, respectively). Multivariate analysis showed that high RDW was significantly and independently associated with higher rates of 6-month mortality (hazard ratio: 2.909; 95% confidence interval: 1.166-7.257; P = 0.022). RDW was also a significant predictor for 6-month mortality independent of anemia (hazard ratio: 2.811; 95% confidence interval: 1.047-7.551; P = 0.040). CONCLUSIONS We found a significant association between high RDW and in-hospital and 6-month mortality as well as the occurrence of major adverse cardiac event. Meanwhile RDW was found to be a significant predictor for 6-month mortality independent of anemia. Thus, it would be beneficial to use RDW as a risk stratification index to identify high risk intent-to-treat patients.

Abstract
Red blood cell distribution width (RDW) is a routine red blood cell count parameter which has been shown to be associated with inflammatory parameters. Recently, some authors proposed that RDW seems to be a marker of an adverse lipidic profile. In order to clarify whether RDW is related to inflammation, plasma lipids, or both, we determined anthropometric, hematimetric, inflammatory and lipidic parameters in 1111 healthy subjects. RDW correlated directly with age, body mass index (BMI), inflammatory parameters (plasma viscosity, erythrocyte sedimentation rate (ESR), fibrinogen, leukocyte and neutrophil count), and inversely with iron and hematimetric parameters (P < 0.05). When subjects were divided according to gender, RDW correlated inversely with triglycerides only in women (P < 0.05). When subjects were classified into RDW-quartiles, increased RDW values were accompanied by decreased serum iron levels and hematimetric indices (P < 0.01), whereas age and inflammatory markers increased according to RDW-quartiles (P < 0.001 and P < 0.05, respectively). However, plasma lipids did not change with increasing RDW-quartiles (P > 0.05). In the linear regression analysis, age, hemoglobin, MCV (beta coefficient: 0.202, -0.234, -0.316, P < 0.001) and fibrinogen (beta coefficient: 0.059, P = 0.048) were the only independent predictors of RDW. The present study indicates that RDW is associated with inflammatory markers and hematimetric indices, but not with plasma lipid levels in a healthy population.

Abstract
Red blood cell distribution width (RDW) was found to be a useful parameter in a variety of cardiovascular and thrombotic disorders. Therefore, we conducted a retrospective case-control study to establish whether an association exists between RDW and venous thrombosis. The study population consisted of 431 consecutive patients who received a diagnosis of venous thrombosis in the emergency department (ED), thus including cases of superficial venous thrombosis, deep vein thrombosis (DVT), and/or pulmonary embolism (PE). The control population consisted of 967 matched outpatients who underwent routine laboratory testing. The RDW values were found to be significantly increased in patients with venous thrombosis compared to controls, with an incremental trend of values from patients with superficial thrombosis, isolate DVT, to PE. Increased RDW values were an independent risk factor for isolate DVT and PE, displaying a relative risk that was greater in patients with provoked DVT and PE that in those with unprovoked thrombosis after multiple adjustment for age, gender, hemoglobin, and mean corpuscular volume. Interestingly, RDW also exhibited a significant diagnostic performance at ED admission, displaying an area under the curve of 0.65 (95% confidence interval [CI] 0.62 to 0.68; p <0.001) for all cases of venous thrombosis, 0.63 (95% CI 0.59 to 0.68; p <0.001) for isolate DVT, and 0.70 (95% CI 0.65 to 0.75; p <0.001) for PE. The results of this study suggest that increased RDW not only is associated with venous thrombosis but may also increase the efficiency of baseline risk assessment of patients with suspected venous thrombosis on ED admission.
