Relation Between Red Blood Cell Distribution Width and Cardiovascular Event Rate in People With Coronary Disease

BACKGROUND: Higher levels of red blood cell distribution width (RDW) may be associated with adverse outcomes in patients with heart failure. We examined the association between RDW and the risk of all-cause mortality and adverse cardiovascular outcomes in a population of people with coronary disease who were free of heart failure at baseline. METHODS AND RESULTS: We performed a post hoc analysis of data from the Cholesterol and Recurrent Events study. Baseline RDW was measured in 4111 participants who were randomized to receive pravastatin 40 mg daily or placebo and followed for a median of 59.7 months. We used Cox proportional hazards models to examine the association between RDW and adverse clinical outcomes. During nearly 60 months of follow-up, 376 participants died. A significant association was noted between baseline RDW level and the adjusted risk of all-cause mortality (hazard ratio per percent increase in RDW, 1.14; 95% confidence interval, 1.05 to 1.24). After categorization based on quartile of baseline RDW and further adjustment for hematocrit and other cardiovascular risk factors, a graded independent relation between RDW and death was observed (P for trend=0.001). For instance, participants with RDW in the highest quartile had an adjusted hazard ratio for death of 1.78 (95% confidence interval, 1.28 to 2.47) compared with those in the lowest quartile. Higher levels of RDW were also associated with increased risk of coronary death/nonfatal myocardial infarction, new symptomatic heart failure, and stroke. CONCLUSIONS: We found a graded independent relation between higher levels of RDW and the risk of death and cardiovascular events in people with prior myocardial infarction but no symptomatic heart failure at baseline.     

Red Cell Distribution Width and Additive Risk Prediction for Major Bleeding in Non-ST-segment Elevation Acute Coronary Syndrome

Introduction and objectives

Red cell distribution width has been linked to an increased risk for in-hospital bleeding in patients with non-ST-segment elevation acute coronary syndrome. However, its usefulness for predicting bleeding complications beyond the hospitalization period remains unknown. Our aim was to evaluate the complementary value of red cell distribution width and the CRUSADE scale to predict long-term bleeding risk in these patients.

Methods

Red cell distribution width was measured at admission in 293 patients with non-ST-segment elevation acute coronary syndrome. All patients were clinically followed up and major bleeding events were recorded (defined according to Bleeding Academic Research Consortium Definition criteria).

Results

During a follow-up of 782 days [interquartile range, 510-1112 days], events occurred in 30 (10.2%) patients. Quartile analyses showed an abrupt increase in major bleedings at the fourth red cell distribution width quartile (> 14.9%; P = .001). After multivariate adjustment, red cell distribution width > 14.9% was associated with higher risk of events (hazard ratio = 2.67; 95% confidence interval, 1.17-6.10; P = .02). Patients with values ≤ 14.9% and a CRUSADE score ≤ 40 had the lowest events rate, while patients with values > 14.9% and a CRUSADE score > 40 points (high and very high risk) had the highest rate of bleeding (log rank test, P < .001). Further, the addition of red cell distribution width to the CRUSADE score for the prediction of major bleeding had a significant integrated discrimination improvement of 5.2% (P < .001) and a net reclassification improvement of 10% (P = .001).

Conclusions

In non-ST-segment elevation acute coronary syndrome patients, elevated red cell distribution width is predictive of increased major bleeding risk and provides additional information to the CRUSADE scale.     

快速性房性心律失常患者红细胞分布宽度与左心房内径的关系

目的探讨快速性房性心律失常患者红细胞分布宽度(RDW)与左心房内径(LAD)的关系。方法选择2013年10月至2014年8月在我院行动态心电图检查证实为快速性房性心律失常患者,搜集RDW、心脏彩超等临床资料,回顾性研究RDW与LAD的关系。结果根据RDW值由低到高三等分组,组间比较RDW、LAD存在显著性差异(P0.05),随RDW值增高左心室舒张期末内径和LAD增高。Pearson相关分析显示,RDW水平与房性心律失常Kleiger分级(r=0.280,P=0.000)、LAD(r=0.297,P=0.000)呈正相关;以快速性房性心律失常(Kleiger分级1~3级=0,Kleiger分级4~6级=1)为因变量进行二分类Logistic多元回归分析显示,RDW(OR=1.215)、LAD(OR=1.024)是快速性房性心律失常的危险因素。结论快速性房性心律失常患者RDW与LAD具有相关性,两者均为快速性房性心律失常的危险因素。     

Red Cell Distribution Width in Patients with Obstructive Sleep Apnea Syndrome

Background  

Red cell distribution width (RDW) has been shown to be associated with adverse outcomes in left-sided heart failure, pulmonary hypertension, and in patients in the ICU. However, the role of RDW is unknown in patients with obstructive sleep apnea syndrome (OSAS), especially in OSAS patients with cardiovascular diseases.     

Red Blood Cell Distribution Width is Independently Correlated With Diurnal QTc Variation in Patients With Coronary Heart Disease

To investigate the relationship between red blood cell distribution width (RDW) and diurnal corrected QT (QTc) variation in patients with coronary heart disease.This retrospective study included 203 patients who underwent coronary angiography between February 2013 and June 2014. RDW values and dynamic electrocardiography (Holter) results were collected to investigate the relationship between RDW and diurnal QTc variation.Patients were separated into three groups (A, B, and C) by binning their RDW values in an ascending order. RDW values, coronary artery scores and diurnal QTc variations were significantly different among these groups (P < 0.05). While coronary artery scores gradually rose with increased RDW, diurnal QTc variation decreased. Pearson''s correlation analysis was applied to control for confounding factors, and multiple correlation analysis showed that coronary artery score was positively correlated with RDW (r = 0.130, P = 0.020), while it was not correlated with the diurnal QTc variation (r = −0.226, P = 0.681). RDW was negatively correlated with diurnal QTc variation (r = −0.197, P = 0.035).RDW is independently associated with diurnal QTc variation in patients with coronary heart disease.     

Assessment of the Relationship Between Red Cell Distribution Width and Multiple Sclerosis

Accumulating data have shown that immune and inflammatory factors are involved in the pathogenesis of multiple sclerosis (MS), and loss of polyunsaturated fatty acids from plasma and blood cell membranes has also been reported in patients with MS, contributing to the variation of erythrocyte deformability. Therefore, the aim of this investigation was to assess the association between red blood cell distribution width (RDW) and MS.A total of 109 patients with MS and 130 healthy individuals were enrolled into the study, and MS patients receiving treatment of subcutaneous recombinant Rebif (IFN-β1a) were followed retrospectively. Complete blood cell counts and Expanded Disability Status Scale (EDSS) score were evaluated in patients with MS before and after treatment.RDW values were significantly higher in patients with MS compared with the controls (13.6 ± 0.89 vs 12.8 ± 0.38, P < 0.001); a positive correlation between RDW and EDSS score was observed in patients with MS (r = 0.789, P < 0.001). Significant differences in the value of RDW and EDSS score were observed between treatment-naive patients and treated patients (13.6 ± 0.95 vs 12.7 ± 0.44, P < 0.001; 3.6 ± 1.39 vs 1.5 ± 0.60, P < 0.001). RDW was associated independently with MS in logistic regression analysis (odds ratio = 7.007; 95% confidence interval [CI] 3.461–14.187; P < 0.001), and receiver-operating characteristics (ROC) analysis showed that a RDW measurement >13.11% evaluated MS with a sensitivity of 70.0% and a specificity of 84.7%, and the area under the ROC curve for RDW was calculated as 0.80 (95% CI 0.739–0.859, P < 0.001). The level of RDW was decreased in treatment responders with the reduction of EDSS score; a strong relationship was also observed in treatment responders between RDW and EDSS score (r = 0.733, P < 0.001), and covariance analysis indicated RDW values decreased significantly in treatment responders (P = 0.025).Our results suggest that elevated RDW values are associated with EDSS score in patients with MS, and the relationship is remarkably influenced by Rebif treatment; RDW may be a useful marker to estimate disability status and treatment effectiveness in patients with MS.
