Abstract
BACKGROUND "Slow flow" is one very important concept in modern fundamental and clinical biomedicine. Slow coronary flow is indicative of delayed filling of the terminal coronary artery vessels, occurring in the absence of significant coronary stenosis. This group patient of patients exhibits a high incidence of disability and represents a significant financial and material burden for the state and the healthcare system in general. OBJECTIVE The primary objective of our study was to examine patients with slow coronary flow. METHODS We studied the standard parameters recommended by the international health care system (electrocardiography (by Medica QRS-12, Germany), through the electrical activity of a patient's heart by the electrical impulses (beating) of the heart; HC1(Germany); coagulogramma by Coatron M1 (Germany), troponin by AQT 90 (Germany); general blood test we used automatic human counting device HC1(Germany). Also, we investigate the original parameters (non-standard parameters, which we use in this pilot study) that we were first studied for this diagnosis and non-standard parameters. RESULTS A general blood test showed that patients with slow flow had a higher blood leukocyte count than the control group, but the amount of hemoglobin was normal, the hematocrit was much higher than in the control group, and the platelet count was close to the lower limit of clinical standards.We obtained details of blood flow by coagulation situation, such as prothrombin time, prothrombin index, international normalized ratio, activated partial thromboplastin time, thrombin time, fibrinogen, and rheological properties such as index of erythrocyte aggregability, index of erythrocyte deformability, plasma viscosity, in silico blood rheological index. CONCLUSSION Blood flow can be considered as a superposition of vortices with similar frequencies and wave vectors that change after bifurcations or other obstacles in the vascular network. These factors together determine the conditions for structuring the flow of moving blood. Disruption or alteration of these factors results in slow flow. It has been found that the speed of blood flow in the coronary arteries depends on changes in the number and function of red blood cells. Slow flow is directly influenced by the aggregation and deformation of red blood cells, their number, and plasma viscosity. Consequently, the rheological status plays a crucial role in determining blood flow and its velocity.

Abstract
Coronary slow flow (CSF) is characterized by slow progression of coronary angiography without epicardial stenosis. The aim of this study was to explore the potential biomarkers and regulatory mechanism for CSF. Peripheral blood mononuclear cells from 3 cases of CSF and 3 healthy controls were collected for high-throughput sequencing of mRNA and miRNA, respectively. The differentially expressed mRNAs (DE-mRNAs) and miRNAs (DE-miRNAs) was identified. A total of 117 DE-mRNAs and 32 DE-miRNAs were obtained and they were mainly enriched in immune and inflammatory responses. Twenty-six DE-mRNAs were the predicted target genes for miRNAs by RAID, and then the regulatory network of 15 miRNAs were constructed. In addition, through the PPI network, we identified the three genes (FPR1, FPR2 and CXCR4) with larger degrees as hub genes. Among them, FPR1 was regulated by hsa-miR-342-3p, hsa-let-7c-5p and hsa-miR-197-3p and participated in the immune response. Finally, we validated the differential expression of hub genes and key miRNAs between 20 CSF and 20 control. Moreover, we found that miR-342-3p has a targeted regulatory relationship with FPR1, and their expression is negatively correlated. Then we established a hypoxia/reoxygenation (H/R) HUVEC model and detected FPR1, cell proliferation and apoptosis. Transfection with miR-342-3p mimics can significantly promote the proliferation of HUVEC under H/R conditions. FPR1 were associated with CSF as a biomarker and may be regulated by miR-342-3p potential biomarkers.

Abstract
Coronary slow flow is taken to be indicative of delayed filling of terminal vessels of the coronary arteries in the absence of coronary stenosis, as detected using coronary angiography. Patients suffering from coronary slow flow typically experience recurrent chest pain, thereby markedly affecting their quality of life. The etiology and pathogenesis of coronary slow flow, which is gradually attracting clinical attention, have yet to be sufficiently established, although it is currently believed that they may be associated with endothelial dysfunction in the coronary arteries, inflammatory response, abnormalities in microvascular reserve function, subclinical atherosclerosis, blood cell and platelet abnormalities, and genetic factors. In this review, we provide a brief overview of recent progress in research on the pathogenesis of coronary slow flow with a view toward elucidating the possible underlying pathogenesis and identify targets and directions for the treatment of this condition.

Abstract
BACKGROUND Coronary slow flow (CSF) can occur due to various factors, such as inflammation, small vessel disease, endothelial dysfunction, and inadequate glucose control. However, the exact pathological mechanisms behind CSF remain incompletely understood. The objective of this study was to identify the risk factors associated with slow coronary flow in individuals with Type 2 Diabetes Mellitus (T2DM) who have non-obstructive coronary artery disease (CAD) and experience CSF. METHODS We conducted a prospective cohort study involving 120 patients with T2DM who were referred for invasive coronary angiography due to typical chest pain or inconclusive results from non-invasive tests for myocardial ischemia. Using a 2 × 2 design, we categorized patients into groups based on their glycemic control (adequate or poor) and the presence of CSF (yes or no), defined by a TIMI frame count > 27. All patients had non-obstructive CAD, characterized by diameter stenosis of less than 40%. We identified many variables associated with CSF. RESULTS Our investigation revealed no significant differences in age, sex, family history of coronary artery disease, ECG ischemia abnormalities, or echocardiographic (ECHO) data between the groups. In patients with adequate glycemic control, hypertension increased the risk of CSF by 5.33 times, smoking by 3.2 times, while dyslipidemia decreased the risk by 0.142. Additionally, hematocrit increased the risk by 2.3, and the platelet-to-lymphocyte ratio (PLR) increased the risk by 1.053. Among patients with poor glycemic control, hematocrit increased the risk by 2.63, and the Neutrophil-to-Lymphocyte Ratio (NLR) by 24.6. Notably, NLR was positively correlated with glycemic control parameters in T2DM patients with CSF. CONCLUSIONS In T2DM patients with CSF, various factors strongly correlate with glycemic control parameters and can be employed to predict the likelihood of CSF. These factors encompass hypertension, smoking, increased body mass index (BMI), elevated platelet count, hematocrit, NLR, PLR, and C-reactive protein (CRP).

Abstract
BACKGROUND Diabetes is a serious and quickly expanding global health problem. Cardiovascular disease is the leading cause of mortality in type 2 diabetes mellitus (T2DM) patients. Coronary slow flow (CSF) is characterised by delayed distal perfusion during coronary angiography with normal coronary arteries. This study aimed to investigate the correlation between CSF and inflammatory markers regarding glycemic status in T2DM. METHODS This cross-sectional study included 120 patients who were divided equally into 4 groups according to their glycemic control and presence or absence of coronary slow flow: Group I included patients with T2DM with good glycemic control without CSF; Group II included patients with T2DM with good glycemic control and CSF; Group III included patients with T2DM with poor glycemic control without CSF; and Group IV included patients with T2DM with poor glycemic control and CSF. The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), C-reactive protein (CRP), platelets, hematocrit, and haemoglobin were also evaluated as risk factors for coronary slow flow. RESULTS This study showed that body mass index (BMI), hematocrit level, NLR, and CRP demonstrated a moderate but significant correlation (r = 0.53) with CSF in poorly controlled T2DM. NLR cutoff > 2.1 could predict CSF in poorly controlled T2DM with a modest sensitivity and specificity. A 1.9 increase in HbA1c increases the likelihood of coronary slow flow. Dylipidemia increases the likelihood of coronary slow flow by 0.18 times. Other predictors for coronary slow flow include NLR, PLR, CRP, platelets, hematocrit, and hemoglobin. The effect of the predictors is still statistically significant after being adjusted for glycemic status, age, and sex (p < 0.001). CONCLUSIONS Poor glycemic control increases the incidence of CSF. This supports the hypothesis that CSF is related to endothelial dysfunction as poor glycemic control causes endothelial dysfunction due to inflammation.

Abstract
Background Although the pathophysiology of coronary slow flow (CSF) has not been fully elucidated, emerging data increasingly support potential role for subclinical diffuse atherosclerosis in the etiology of CSF. We aimed to investigate relationship between atherogenic indices and CSF. Methods 130 patients with CSF diagnosed according to Thrombolysis in Myocardial Infarction (TIMI)-frame count (TFC) method and 130 controls who had normal coronary flow (NCF) were included in this retrospective study. Atherogenic indices (atherogenic index of plasma [AIP], Castelli risk indices I and II [CRI-I and II]) were calculated using conventional lipid parameters. Results The logistic regression analyses demonstrated that AIP (OR, 5.463; 95% confidence interval [CI], 1.357–21.991; p = 0.017) and CRI-II (OR, 1.624; 95% CI, 1.138–2.319; p = 0.008) were independent predictors of CSF. Receiver operating characteristic analysis showed that the optimal cutoff value to predict the occurrence of CSF was 0.66 for AIP (sensitivity, 59%; specificity, 73%; area under curve [AUC], 0.695; p < 0.001) and 3.27 for CRI-II (sensitivity, 60%; specificity, 79%; AUC, 0.726; p < 0.001). Conclusions AIP and CRI-II levels were independent predictors of CSF. Prospective studies in larger cohorts of patients may elucidate the role of atherogenic dyslipidemia in the pathophysiology of CSF.

Abstract
Recent studies have reported a relationship between the platelet to lymphocyte ratio (PLR) and acute coronary syndromes. The aim of the present study was to investigate the association between PLR and stable coronary artery disease (CAD). A systematic search was conducted based on electronic databases (Cochrane, PubMed, Elsevier, Medline, and Embase). A total of 14 studies (n = 4,871) were included in the meta-analysis. Compared with the non-CAD group, PLR was significantly higher in CAD group (P = .002). After further classification according to the Gensini score, the cases with atherosclerosis demonstrated a higher PLR than those without atherosclerosis (P < .001). Platelet to lymphocyte ratio was higher in the severe atherosclerosis group compared with the mild atherosclerosis group (P < .001). Compared with the poor coronary collateral circulation (CCC) group, PLR was significantly lower in the good CCC group (P < .001). The PLR was significantly higher in patients with coronary slow flow (CSF) than those with normal coronary flow (P = .01). On the basis of current evidence, an elevated PLR was associated with stable CAD, and it might be useful for predicting CAD severe stenosis, collateral circulation, and CSF. Future studies are needed to clarify the relationship between PLR and stable CAD.

Abstract
Introduction Atherosclerosis is a chronic inflammatory process and inflammation is an important component of acute coronary syndrome (ACS). Platelet-to-lymphocyte ratio (PLR) is a useful parameter showing the degree of the inflammatory response. Aim To explore the association between PLR and long-term mortality in patients with ACS. Material and methods A total of 538 patients who had a diagnosis of ACS between January 2012 and August 2013 were followed up to 60 months. On admission, blood sampling to calculate PLR and detailed clinical data were obtained. Results In total, 538 patients with a mean age of 61.5 ±13.1 years (69% male) were enrolled in the study. Median follow-up was 79 months (IQR: 74–83 months). Patients were divided into 3 tertiles based on PLR levels. Five-year mortality of the patients was significantly higher among patients in the upper PLR tertile when compared with the lower and middle PLR tertile groups (55 (30.7%) vs. 27 (15.0%) and 34 (19.0%); p < 0.001, p = 0.010 respectively). In the Cox regression analysis, a high level of PLR was an independent predictor of 5-year mortality (OR = 1.005, 95% CI: 1.001–1.008, p = 0.004). Kaplan-Meier analysis according to the long-term mortality-free survival revealed the higher occurrence of mortality in the third PLR tertile group compared to the first (p < 0.001) and second tertiles (p = 0.009). Conclusions PLR, which is an easily calculated and universally available marker, may be useful in long-term risk classification of patients presenting with ACS.

Abstract
OBJECTIVE Coronary slow flow (CSF) is characterized by delayed opacification of distal epicardial coronary arteries without significant coronary stenosis. In addition, The changes of lipoprotein-associated phospholipase A2 (Lp-PLA2) as a significant predictive factor for CSF remain controversial. The study aims to investigate the association between plasma Lp-PLA2 and CSF. METHODS In this retrospective study, 170 consecutive patients who underwent coronary angiography were enrolled in Beijing Anzhen Hospital from January 2017 to September 2019, and were divided into CSF group and normal control groups. According to coronary blood flow rate measured by the thrombolysis in myocardial infarction frame count (TFC) method, CSF was defined as TFC > 27. Serum Lp-PLA2 levels were measured in an enzyme-linked immunosorbent assay. RESULTS Lp-PLA2 levels were higher in the CSF group than in the control group (288.6 ± 50.3 versus 141.9 ± 49.7, P < 0.001) and were significantly correlated with the mean coronary artery thrombolysis in myocardial infarction (TIMI) frame count (r = 0.790, P<0.001). Logistic regression analysis showed that high Lp-PLA2 was independently associated with CSF after adjustment for conventional risk factors (OR = 1.040, CI = 1.022-1.059, P<0.001). Male sex (OR = 2.192, CI = 1.161-4.140, P = 0.016) and hypertension (OR = 1.965, CI = 1.034-3.736, P = 0.039) were also CSF risk factors. Receiver-operating characteristic curve (ROC) analysis showed that Lp-PLA2 levels can predict CSF severity; the predictive power was higher than the other risk factors. CONCLUSION Our study demonstrated that patients with CSF had higher circulating levels of Lp-PLA2 than normal controls. After adjustment for potential confounders, increased Lp-PLA2 was independently associated with presence of CSF.

C-reactive protein (CRP) and high-sensitivity CRP (hsCRP), along with a series of hematological indices, platelet to lymphocyte ratio (PLR), neutrophil to lymphocyte ratio (NLR), mean platelet volume (MPV), platelet distribution width (PDW), and red blood cell distribution width (RDW), are regarded to be related to the incidence of no-reflow or slow flow. Clinical studies were retrieved from the electronic databases of PubMed, EMBASE, Google Scholar, Clinical Trials, and science direct from their inception to August 24, 2019. A total of 21 studies involving 7403 patients were included in the meta-analysis. Pooled analysis results revealed patients with higher hsCRP (odds ratio [OR] = 1.03, 95% confidence interval [CI], 1.01-1.05, P = .006), hsCRP (OR = 1.04, 95% CI: 1.0-1.08, P = .012), NLR (OR = 1.23, 95% CI: 1.11-1.37, P < .0001), PLR (OR = 1.13, 95% CI: 1.07-1.20, P < .0001), and MPV (OR = 2.13, 95% CI: 1.57-2.90, P < .0001) all exhibited significantly higher no-reflow incidence, but there was no significant association between no-reflow risk and RDW or PDW. Patients with higher CRP/hsCRP also performed higher rate of slow flow (OR = 1.06, 95% CI: 1.01-1.11, P = .018). Preangiographic CRP/hsCRP could independently predict no-reflow and slow flow. Moreover, some hematological indices are associated with no-flow.

Abstract
Objectives Platelet/lymphocyte ratio is considered to be a recent biomarker which is not only related with inflammation but also associated with the atherosclerotic process. In this study, we aimed to investigate the relationship between carotid artery stenosis, platelet/lymphocyte ratio, neutrophil/lymphocyte ratio, and mean platelet volume in patients undergoing carotid endarterectomy. Methods A total of 160 patients (127 males, 33 females; mean age 69.98 ± 9.76 years; range 48–92 years), who were undergoing carotid endarterectomy due to severe carotid artery stenosis, were evaluated and compared with 201 patients (140 males, 61 females, mean age 66.30 ± 9.24 years, range 41–90 years) without severe carotid artery stenosis. The patients were divided into four groups with respect to the carotid artery stenosis as: Group I (<50% stenosis), Group II (50–70% stenosis), Group III (70–90% stenosis), and Group IV (90–99% stenosis). Results Platelet/lymphocyte ratio, neutrophil/lymphocyte ratio and mean platelet volume were found higher in Group IV (patients with severe carotid artery stenosis) (p < 0.01) and were positively correlated with the degree of stenosis (p < 0.01). Platelet/lymphocyte ratio is an independent predictor for post operative stroke (p = 0.047) at multivariate analysis. A threshold level of 145.304 of platelet/lymphocyte ratio combined with a sensitivity 83.3% and specificity 73.8% (95% CI, 0.802–0.921, area under the curve = 0.862 ± 0.03; p = 0.002) for the identification of post operative stroke. Conclusions This retrospective study suggests that platelet/lymphocyte ratio in the blood which was taken preoperatively could be considered as an additional, easy, and inexpensive method to predict a possible higher incidence of postoperative stroke after carotid endarterectomy.

Abstract
Identification of rapid, inexpensive, and reliable prognostic factors can improve survival estimation and guide healthcare in patients with acute heart failure (AHF). In this study, we aimed to determine the prognostic value of the platelet-to-lymphocyte ratio (PLR) in patients with AHF. A total of 443 patients from two hospitals met the inclusion criteria from January 2010 to December 2017. Univariate and multivariate Cox analyses were performed to determine the association of PLR with survival. All-cause mortality was analysed using the Kaplan-Meier method. The 6-month survival rate for patients according to PLR quartiles (<110.63, 110.63-139.23, 139.23-177.17, and >177.17) were 90.09%, 76.79%, 50.07%, and 37.27%, respectively (p < 0.001). Univariate analysis identified high PLR (>110.63), old age (≥73 years), smoking habit, low estimated glomerular filtration rate (<57), and high platelet count (≥198 × 109/l) as poor prognostic factors for survival. In the multivariate analysis, after adjusting for confounding factors, the third (hazard ratio [HR] = 3.118, 95% confidence interval [CI] = 1.668-5.386, p < 0.001) and fourth (HR = 2.437, 95% CI = 1.302-3.653, p < 0.001) quartiles of PLR were identified as independent prognostic factors in patients with AHF. A higher PLR was associated with poor clinical outcomes in patients with AHF and might be a novel marker in AHF management.

Abstract
Ischemia/reperfusion (I/R) injury is associated with primary percutaneous coronary intervention (PPCI). The current study was performed to compare the effect of tirofiban and recombinant human pro-urokinase (rh-proUK) on the improvement of coronary slow blood after PPCI.Sixty-five ST elevation myocardial infarction (STEMI) patients treated with rh-proUK and an equal number treated with tirofiban after PPCI were employed in the current study. The clinicopathological information regarding the biochemical parameters, thrombolysis in myocardial infarction (TIMI) grade, hemodynamics parameters, thrombus core (TS), sum-STR, left ventricular ejection fraction (LVEF), blood routine parameters, high-sensitivity C-reactive protein (CRP) level, uric acid, hepatorenal function, electrocardiogram (ECG), and echocardiography before and after the interventions were collected. The differences in those parameters between the 2 groups then compared with assess the treatment effect and side effects associated with the both therapies.The results showed that the TIMI level post-intervention (P = .03), the proportion of TIMI myocardial perfusion grade level III (P = .04), the changes in thrombus score (P < .001) in rh-proUK group were significantly higher than those in tirofiban group while the corrected TIMI Frame Count (CTFC) (P = .02), the incidence of slow flow (P = .02), the thrombus score post-intervention (P < .001), the stent length (P = .02), and the number of receiving administration of sodium nitroprusside (P = .01) were significantly lower than those in tirofiban group. Moreover, the levels of CK (P < .001), CK-MB (P = .01), and NT-proBNP 24-hour post-intervention (P < .02) were significantly lower in rh-proUK group than those in tirofiban group and the sum-STR right after the intervention (P < .03) of rh-proUK group was significantly higher than that of tirofiban group. No significant difference was detected between the 2 therapies regarding major adverse cardiac events (MACE).The findings outlined in the current study showed that the improvement effect of rh-proUK on blood flow condition was stronger right after the intervention and the therapy had a similar safety when compared with tirofiban during a 30-day follow-up.

Abstract
The platelet to lymphocyte ratio (PLR) is an integrated reflection of 2 opposite thrombotic/inflammatory pathways that are easily calculated from a complete blood count. The PLR initially served as a systemic inflammatory biomarker to predict the prognosis of neoplastic diseases. In recent years, the PLR has been used as a prognostic marker in cardiovascular (CV) conditions. In this review, we consider the evidence regarding the association of the PLR with CV disease (CVD) and its possible use as a prognostic marker of CVD. The role of PLR has been investigated in CV conditions in several studies. We assessed clinical trials using PubMed, EMBASE, and Web of Science (up to April 18, 2018) to evaluate the association between PLR and mortality/major adverse cardiac events in these conditions. Most of these studies reported significant relationships between a high PLR and diverse outcomes. In conclusion, we suggest that PLR is a cheap and easily available systemic inflammatory marker that can predict distinct outcomes in different types of CVD.

Abstract
Introduction The purpose of this study was to compare the value of hematological parameters, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV), as indicators of anterior uveal segment involvement in patients with Behcet’s disease (BD). Patients and methods Hospital-based records of a total of 912 patients with BD from the dermatology clinic and healthy volunteers from the checkup clinic were assessed retrospectively. After applying the exclusion criteria of the study, 71 of the BD patients with anterior uveitis, 69 of the BD patients without ophthalmological pathology and 151 healthy volunteers were included in the study. MPV, PLR, and NLR values of patients and healthy volunteers were compared. Results All MPV, PLR, and NLR values of patients who had anterior uveitis were significantly higher than those of other patients and healthy volunteers. Statistically, considering area under curves (ratio): NLR was 0.725 (0.653–0.797), P<0.001; PLR was 0.600 (0.523–0.676), P=0.012, and MPV was 0.358 (0.279–0.437), P<0.001. Conclusion MPV, PLR, and NLR are all valuable for assessment of anterior uveal segment involvement in patients with BD. However, the NLR seems to be better than the PLR and MPV for indicating anterior uveitis due to BD.

Abstract
INTRODUCTION Inflammation and increased platelet activation play a crucial role in the initiation and progression of atherosclerosis. Platelet-to-lymphocyte ratio (PLR) has recently been reported as a new independent predictor for major adverse cardiovascular events in cardiovascular diseases. AIM To investigate the relation between PLR and cardiovascular mortality in patients with intermittent claudication or critical limb ischemia (CLI) or both. MATERIAL AND METHODS In our retrospective study, 602 consecutive patients who were admitted to a large tertiary hospital with the diagnosis of symptomatic peripheral arterial occlusive disease (PAOD) were included. Patients were divided into two groups according to their PLR as follows: high PLR (PLR > 142) and low PLR (PLR ≤ 142) groups. RESULTS During the follow-up period (median: 33.8 months (interquartile range: 21-45)), 131 deaths occurred out of 602 (21.8%) patients. Cardiovascular mortality was found to be significantly higher in the high PLR group compared to the low PLR group (31.6% vs. 17.2 %; p < 0.001). Even after adjustment for various risk factors, PLR > 142 and age were found to be independent predictors of long-term cardiovascular mortality in Cox regression analysis (hazard ratios (95% confidence interval): 1.03 (1.01-1.04) and 1.04 (1.02-1.06), p < 0.001 and p < 0.001, respectively). CONCLUSIONS Platelet-to-lymphocyte ratio, which is one of the parameters of routine complete blood count, reflects increased inflammatory status, platelet activation and aggregation. PLR is a cheap and readily available marker that has the ability to improve risk stratification provided by conventional risk scores in predicting long-term cardiovascular mortality in PAOD.

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
OBJECT Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are simple, inexpensive prognostic markers for various conditions. The objective of this study was to determine the prognostic significance of NLR and PLR in patients with multiple myeloma (MM) in terms of survival. METHOD A retrospective chart review study was conducted for 175 patients who met the criterion of diagnosis for MM between January 2004 and September 2014. RESULT The median age of diagnosis was 69 years. Patients were divided into high and low NLR and PLR groups according to cutoff points from the receiver operating characteristic curve (2.78 and 155.58, respectively). The high NLR and PLR groups were associated with lower albumin level and higher staging. The high NLR group experienced inferior median survival compared with the low NLR group (37 vs. 66 months; log-rank P-value 0.005). However, there was no significant difference in median survival between the high and low PLR groups (45 vs. 62 months; P = 0.077). Multivariate analysis demonstrated that NLR is an independent predictor for OS of MM (HR 2.892; P = 0.009). CONCLUSION We conclude that NLR is an independent prognostic factor for OS in MM.
