Abstract
Background The mean platelet volume to platelet count ratio (MPV/PC) has been investigated in the diagnosis, prognosis and risk stratification in several diseases. However, the predictive role of MPV/PC in left atrial stasis (LAS) of non-valvular atrial fibrillation (NVAF) patients remains unknown. Methods A total of 217 consecutive NVAF patients undergoing transesophageal echocardiogram (TEE) evaluation were retrospectively enrolled. The demographic, clinical, admission laboratory and TEE data were extracted and analyzed. Patients were categorized into those with or without LAS. The associations between the MPV/PC ratio and LAS were assessed by multivariate logistic regression analysis. Results There were 24.9% (n = 54) patients with LAS according to TEE. Compared with patients without LAS, the MPV/PC ratio was significantly higher in those with LAS (5.6±1.6 vs 4.8±1.0, P < 0.001). After multivariable adjustment, higher MPV/PC ratio levels (OR 1.747, 95% CI 1.193-2.559, P = 0.004) were positively associated with LAS, with the optimal cut-point for LAS prediction of 5.36 (area under the curve, AUC = 0.683, sensitivity 48%, specificity 73%, 95% CI 0.589-0.777, P < 0.001). The stratification analysis showed that a significant positive correlation between MPV/PC ratio ≥5.36 and LAS in patients of male, younger (<65 years), paroxysmal AF, without history of stroke/TIA, CHA2DS2-VASc score ≥2, left atrial diameter (LAD) ≥40mm and left atrial volume index (LAVI) >34mL/m2 (all P < 0.05). Conclusion Increasing MPV/PC ratio was associated with an increased risk of LAS, which was mainly reflected in the subgroups of male, younger (<65 years), paroxysmal AF, without history of stroke/TIA, CHA2DS2-VASc score ≥2, LAD ≥40mm and LAVI >34mL/m2 patients.

Abstract
Ischemic stroke risk in atrial fibrillation differs from patient to patient, depending on numerous variables. Many attempts have been made to translate this difference into simple numbers and to compare it to the hemorrhagic risk of anticoagulation. Different clinical scores have been studied to define a clear strategy. One score, the CHA2DS2-VASc score, has been extensively and successfully applied worldwide. Nevertheless, it is not yet the “perfect instrument”. Many proposals have been made to integrate its clinical parameters with some biomarkers to improve its predictive power. This short review describes some of these biomarkers and their possible implications in potentiating the efficacy of clinical scores.

Abstract
BACKGROUND In this study, we aimed to investigate the role of miR-26a and miR-26b in the management of AF. METHODS Real-time PCR was carried out to determine plasma microRNA expression in AF patients pre- and post-radiofrequency ablation. The correlation between the expression of SELP and miR-26a/miR-26b was also studied using luciferase assays to establish a miR-26a/miR-26b/SELP signaling pathway. RESULTS The relative expression of SELP reached its peak in pre-ablation AF ( +) patients, while ablation treatment reduced the expression of SELP in AF ( +) patients. Similarly, AF pigs showed dysregulation of miR-26a/b and SELP, thus verifying the involvement of miR-26a/b and SELP in AF. Meanwhile, the regulatory association between SELP and miR-26a/b was also investigated, and the results showed that the presence of pre-miR-26a/b increased the levels of miR-26a/b and inhibited the mRNA/protein expression of SELP. Finally, using bioinformatic tools and luciferase assays, SELP mRNA was confirmed as the target of miR-26a/b, which affected the effect of AF ablation treatment. CONCLUSIONS RFA helped to restore circulating levels of miR-26, which were reduced in atrial fibrillation. Meanwhile, miR-26 is a potential cause for the elevated plasma levels of pro-thrombogenic SELP in that disease.

Comparison of Immature Platelet Fraction and Factors Associated with Inflammation, Thrombosis and Platelet Reactivity Between Left and Right Atria in Patients with Atrial Fibrillation. J Atr Fibrillation 2021; 13:2459. [PMID: 34950336 DOI: 10.4022/jafib.2459] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2020] [Revised: 12/25/2020] [Accepted: 01/18/2021] [Indexed: 11/10/2022]
Abstract
Background Recent trials found poor temporal relationship between atrial fibrillation (AF) episodes and strokes. Thus, stroke in AF patients probably involves more mechanisms than cardiac embolism. We compared factors of inflammation, thrombosis and platelet reactivity between left (LA) and right atria (RA) and femoral vein (FV) in patients with AF. Methods Blood samples were collected from patients undergoing AF-ablation from the FV, RA and LA for neutrophil to lymphocyte ratio (NLR), immature platelet fraction (IPF) and count (IPC), CD40 ligand, P-selectin and E-Selectin. IPF was measured by an autoanalyzer; CD40 ligand, P-selectin, and E-Selectin were measured by ELISA and NLR was calculated from complete blood counts. Results Sixty-seven patients were included (age 65±10y, 63% male, CHA2DS2-VASc score 2.8±1.8, LA volume index 40±24 mL/m2, 63% paroxysmal AF). There was no difference between FV, RA and LA regarding NLR and CD40 ligand. Factors associated with platelets activity: P-selectin, IPC and IPF% were higher in RA vs LA (60.3 IQR 49.0-76.4 ng/ml vs. 59.3 IQR 49.0-74.7, respectively, p=0.03 for P-selectin, 7.5 IQR 5.2-10 103/μL vs. 7.1 IQR 5-9.8, p<0.01 for IPC, and 3.6 IQR 2.7-5.0 % vs. 3.6 IQR 2.6-4.8, p<0.01 for IPF%). Similar trends were for E-selectin (41.2 IQR 31.1-51.2 ng/mL vs. 38.7 IQR 27.9-50.4 p=0.09). Similar significant differences were found in patients with CHA2DS2-VASC≥2 but not in patients with low score. Conclusions Patients with AF, especially those with CHA2DS2-VASc≥2, have higher markers of thrombogenicity in RA compared to LA. There was no difference in inflammatory properties between the atria.

Platelet Distribution Width Is Associated with P-Selectin Dependent Platelet Function: Results from the Moli-Family Cohort Study. Cells 2021; 10:cells10102737.

Abstract
Defined as an index of platelet size heterogeneity, the platelet distribution width (PDW) is still a poorly characterized marker of platelet function in (sub)clinical disease. We presently validated PDW as a marker of P-selectin dependent platelet activation in the Moli-family cohort. Platelet-bound P-selectin and platelet/leukocyte mixed aggregates were measured by flow cytometry in freshly collected venous blood, both before and after in vitro platelet activation, and coagulation time was assessed in unstimulated and LPS- or TNFα-stimulated whole blood. Closure Times (CT) were measured in a Platelet Function Analyzer (PFA)-100. Multivariable linear mixed effect regression models (with age, sex and platelet count as fixed and family structure as random effect) revealed PDW to be negatively associated with platelet P-selectin, platelet/leukocyte aggregates and von Willebrand factor (VWF), and positively with PFA-100 CT, and LPS- and TNF-α-stimulated coagulation times. With the exception of VWF, all relationships were sex-independent. In contrast, no association was found between mean platelet volume (MPV) and these variables. PDW seems a simple, useful marker of ex vivo and in vitro P-selectin dependent platelet activation. Investigations of larger cohorts will define the usefulness of PDW as a risk predictor of thrombo-inflammatory conditions where activated platelets play a contributing role.

Abstract
Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia worldwide and results in a significantly increased ischemic stroke (IS) risk. IS risk stratification tools are widely being applied to guide anticoagulation treatment decisions and duration in patients with non-valvular AF (NVAF). The CHA2DS2-VASc score is largely validated and currently recommended by renowned guidelines. However, this score is heavily dependent on age, sex, and comorbidities, and exhibits only moderate predictive power. Finding effective and validated clinical biomarkers to assist in personalized IS risk evaluation has become one of the promising directions in the prevention and treatment of NVAF. A number of studies in recent years have explored differentially expressed biomarkers in NVAF patients with and without IS, and the potential role of various biomarkers for prediction or early diagnosis of IS in patients with NVAF. In this review, we describe the clinical application and utility of AF characteristics, cardiac imaging and electrocardiogram markers, arterial stiffness and atherosclerosis-related markers, circulating biomarkers, and novel genetic markers in IS diagnosis and management of patients with NVAF. We conclude that at present, there is no consensus understanding of a desirable biomarker for IS risk stratification in NVAF, and enrolling these biomarkers into extant models also remains challenging. Further prospective cohorts and trials are needed to integrate various clinical risk factors and biomarkers to optimize IS prediction in patients with NVAF. However, we believe that the growing insight into molecular mechanisms and in-depth understanding of existing and emerging biomarkers may further improve the IS risk identification and guide anticoagulation therapy in patients with NVAF.

Abstract
Abstract
Objectives
Mean platelet volume (MPV), platelet distribution width (PDW), and plateletcrit (PCT) possess diagnostic and prognostic capabilities in a variety of diseases. We aimed to establish reference intervals (RI) for platelet indices (PI) in seniors.
Methods
We established direct and indirect RI for MPV, PDW, and PCT in selected reference individuals aged 60 years and older. Abnormal PI were assessed in a population-based setting in the Principality of Liechtenstein, where 37.7% of the whole nation’s population aged 60 years and older had PI determined by hematology analyzers from Sysmex (Horgen, Switzerland).
Results
Among 689 female and 542 male participants, MPV and PDW did not exhibit age- and gender-specific differences, whereas PCT in females also displayed no age-specific differences. Age- and sex-independent RI were 9.3–12.5 fl for MPV and 10.1–16.7% for PDW, whereas the age-independent RI for PCT in women was 0.18–0.37. In males, age-specific RI for PCT were 0.16–0.30 (age 60–69), 0.15–0.33 (age 70–79), and 0.14–0.33 (age 80 and older). The population-based frequency of abnormal PI results was 0.8% (MPV), 1.1% (PDW), and 24.4% (PCT).
Conclusions
Applying novel RI for PI reveals that only approximately 1% of patients exhibit abnormal MPV and PDW. Abnormal PCT is observed much more frequently.

Front Pediatr 2020; 8:329. [PMID: 32766178 PMCID: PMC7381209 DOI: 10.3389/fped.2020.00329] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Accepted: 05/20/2020] [Indexed: 12/20/2022] Open
Abstract
Background: We conducted this systematic review and meta-analysis to investigate the clinical effect of dexmedetomidine in preventing pediatric emergence agitation (EA) or delirium (ED) following anesthesia compared with placebo or other sedatives. Methods: The databases of Pubmed, Embase, and Cochrane Library were searched until 8th January 2020. Inclusion criteria were participants with age<18 years and studies of comparison between dexmedetomidine and placebo or other sedatives. Exclusion criteria included adult studies; duplicate publications; management with dexmedetomidine alone; review or meta-analysis; basic research; article published as abstract, letter, case report, editorial, note, method, or protocol; and article presented in non-English language. Results: Fifty-eight randomized controlled trials (RCTs) and five case-control trials (CCTs) including 7,714 patients were included. The results showed that dexmedetomidine significantly decreased the incidence of post-anesthesia EA or ED compared with placebo [OR = 0.22, 95% CI: (0.16, 0.32), I 2 = 75, P < 0.00001], midazolam [OR = 0.36, 95% CI: (0.21, 0.63), I 2 = 57, P = 0.0003], and opioids [OR = 0.55, 95% CI: (0.33, 0.91), I 2 = 0, P = 0.02], whereas the significant difference was not exhibited compared with propofol (or pentobarbital) [OR = 0.56, 95% CI: (0.15, 2.14), I 2 = 58, P = 0.39], ketamine [OR = 0.43, 95% CI: (0.19, 1.00), I 2 = 0, P = 0.05], clonidine [OR = 0.54, 95% CI: (0.20, 1.45), P = 0.22], chloral hydrate [OR = 0.98, 95% CI: (0.26, 3.78), P = 0.98], melatonin [OR = 1.0, 95% CI: (0.13, 7.72), P = 1.00], and ketofol [OR = 0.55, 95% CI: (0.16, 1.93), P = 0.35]. Conclusion: Compared with placebo, midazolam, and opioids, dexmedetomidine significantly decreased the incidence of post-anesthesia EA or ED in pediatric patients. However, dexmedetomidine did not exhibit this superiority compared with propofol and ketamine. With regard to clonidine, chloral hydrate, melatonin, and ketofol, the results needed to be further tested due to the fact that only one trial was included for each control drug.

Abstract
Atrial fibrillation (AF) is one of the most common types of arrhythmias and increases cardiovascular morbidity and mortality. Current therapeutic approaches to AF that focus on rhythm control have high recurrence rates and no life prolongation value. While possible explanations include toxicity of current therapies, another likely explanation may be that current therapies do not address fundamental mechanisms of AF initiation and maintenance. Inflammation has been shown to affect signaling pathways that lead to the development of AF. This paper reviews the roles of inflammation in the occurrence, development, and mechanisms of AF and reviews the therapeutic implications of the correlation of inflammation and AF.

Abstract
PURPOSE OF REVIEW To critically review the literature describing links between mean platelet volume (MPV) and cardiovascular disease (CVD). We will focus on coronary artery disease (CAD). The MPV is measured routinely as part of a routine blood count. RECENT FINDINGS There is accumulating evidence showing that the MPV may predict CVD, as well as outcomes in patients with CAD. There is also evidence linking MPV and comorbidities (e.g. diabetes mellitus and impaired glycaemic control) that are expected in patients with CAD. The effect on MPV of drugs commonly used to treat CAD has not been clarified, but there is some evidence that they may exert a beneficial effect on the MPV. More specifically, the MPV may predict the effect of antiplatelet drugs (e.g. clopidogrel). There is also evidence relating MPV to stroke, atrial fibrillation, coronary artery ectasia and periprocedural outcomes after percutaneous coronary intervention (PCI). SUMMARY Measuring the MPV may prove useful in CVD risk assessment in patients with established CAD or at risk of developing CAD. Overall, there is evidence pointing to the role of MPV as a contributor rather than simple marker of CVD.

Abstract
Changes of mean platelet volume (MPV) and platelet count (PC) could be a marker or a predictor of acute stroke (AS). We conducted a systematic review and meta-analysis of the published literature on the reporting of MPV and PC in AS. Studies were included in accordance with Patient Population or Problem, Intervention, Comparison, Outcomes, and Setting framework. The PRISMA strategy was used to report findings. Risk of bias was assessed with the Newcastle-Ottawa Scale. We included 34 eligible articles retrieved from the literature. PC was significantly lower in AS patients [standardized mean difference (SMD) = - 0.30, (95% CI: - 0.49 to - 0.11), N = 2492, P = .002] compared with controls (N = 3615). The MPV was significantly higher [SMD = 0.52 (95% CI: 0.28-0.76), N = 2739, P < .001] compared with controls (N = 3810). Subgroup analyses showed significantly lower PC in both ischemic stroke (Difference SMD = -0.18, 95% CI: -0.35-0.01) and hemorrhagic stroke (-0.94, -1.62 to -0.25), but only samples by citrate anticoagulant showed significantly lower result for patients compared to controls (-0.36, -0.68 to -0.04). Ischemic stroke patients had higher MPV (0.57, 0.31-0.83), and samples by Ethylenediaminetetraacetic acid (EDTA) anticoagulant showed significantly higher result for patients compared to controls (0.86, 0.55-1.17). PC and MPV appeared to be significantly different between patients with AS and control populations. MPV was significantly higher in ischemic stroke and PC was significantly lower in both ischemic and hemorrhagic strokes. These characteristics might be related to AS and associated with it. It is advisable to pay attention to elapsed time between phlebotomy and hematology analysis, anticoagulant and hemocytometer types in AS. SYSTEMATIC REVIEW REGISTRATION This meta-analysis is registered on the International Prospective Register of Systematic Reviews (PROSPERO) under registration number CRD42017067864 (https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=67864).

Si-Miao-Yong-An Decoction Protects Against Cardiac Hypertrophy and Dysfunction by Inhibiting Platelet Aggregation and Activation. Front Pharmacol 2019; 10:990. [PMID: 31619988 PMCID: PMC6759602 DOI: 10.3389/fphar.2019.00990] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2019] [Accepted: 08/05/2019] [Indexed: 02/06/2023] Open
Abstract
Objective: The aim of this study was to determine whether Si-Miao-Yong-An decoction (SMYAD) could ameliorate pressure overload-induced heart hypertrophy and its mechanisms. Methods: C57BL/6 mice were subjected to either sham or transverse aortic constriction (TAC) surgery to induce heart hypertrophy. SMYAD (14.85 g/kg/day, ig) or captopril (16.5 mg/kg/day, ig) was administered to the mice for 4 weeks. Cardiac function was evaluated based on echocardiography. Heart hypertrophy was detected using hematoxylin and eosin or wheat germ agglutinin staining. Protein expression of CD41, CD61, and P-selectin were measured with Western blot and immunohistochemistry. The expression levels of atrial natriuretic peptide, brain natriuretic peptide, β-myosin heavy chain, β-thromboglobulin, and von Willebrand factor were evaluated by quantitative polymerase chain reaction. Results: Four weeks after TAC, mice developed exaggerated cardiac hypertrophy and demonstrated a strong decrease in left ventricular ejection fraction compared with sham (29.9 ± 9.3% versus 66.0 ± 9.9%; P < 0.001). Conversely, SMYAD improved cardiac dysfunction with preserved left ventricular ejection fraction (66.5 ± 17.2%; P < 0.001). Shortening fraction was increased by SMYAD, while the left ventricular internal diameter and left ventricular volume were decreased in SMYAD group. SMYAD treatment significantly attenuated cardiac hypertrophy as reflected by the inhibition of atrial natriuretic peptide, brain natriuretic peptide, β-myosin heavy chain mRNA expression, and by the decreasing of cardiac myocyte cross-sectional area. Furthermore, Western blot and immunohistochemistry indicated that the protein expression of platelet aggregation markers (CD41 and CD61) and platelet activation marker (P-selectin) were significantly higher in model mice compared with control. These pathological alterations in TAC-induced mice were significantly ameliorated or blocked by SMYAD administration. Conclusions: Our results suggested that SMYAD exerted its effect by inhibiting platelet aggregation and activation as revealed by CD41/CD61/P-selectin downregulation. Inhibition the activation of the platelets might contribute to the therapeutic effect of SMYAD in failing heart.

Abstract
BACKGROUND Platelet activation is linked with thrombosis, inflammation or heart failure. OBJECTIVE To establish clinical and analytical factors that may favor high mean platelet volume (MPV) and to determine if MPV levels favor major adverse cardiovascular events (MACE). METHODS Stable CHD patients and a control population matched for age, sex and cardiovascular factors. RESULTS 658 CHD patients and 2092 controls were studied. Median age in CHD patients was 33 (25-41) year old with 56% of them being male. No significant differences were seen between MPV values and cardiac complexity (p = 0.308) nor between MPV values in the CHD and control groups (p = 0.911). CHD patients had significant lower platelet count and MPV levels than patients in the control group. In the binary logistic regression analysis NT-pro-BNP levels above 125 pg/ml, thrombocytopenia and having atrial fibrillation/flutter reached statistical significance as predictors of MPV levels above 11 fL. The Kaplan-Meier survival analysis showed no significance between MPV levels higher than 11 fL and MACE, cardiovascular mortality and thrombotic events in a median time follow-up of 6.7(1.5-10.6) years. CONCLUSIONS Atrial fibrillation/flutter, heart failure and thrombocytopenia are predictors of high MPV levels. A MPV above 11 fL is not associated with MACE at a median follow-up time.

Abstract
Objective To assess the relationship between preoperative vitamin D (vitD)
supplementation and the development of postoperative atrial fibrillation
(POAF). Methods The study group consisted of 328 consecutive patients. The ınfluence
of preoperative vitD supplementation on POAF was reviewed in 136 patients
who underwent coronary artery bypass graft surgery with vitD insufficiency
(n=80) and vitD deficiency (n=56). Patients were assigned to receive either
oral vitD (50.000 U) (treatment group, n=68) or not (control group, n=68) 48
hours before surgery. Patients were followed up during hospitalisation
process with respect to POAF. Results There was no significant difference between treatment and control groups with
regards to age, gender, diabetes mellitus, smoking history, chronic
obstructive pulmonary disease, left atrial diameter, and biochemical
parameters. Also, there was no significant difference between these groups
with regards to mean vitD level on both insufficiency and deficiency
patients (24.6±3.7 vs. 24.9±3.9 ng/ml
P=0.837, 11.4±4.9 vs.
10.9±5.2 ng/ml P=0.681, respectively). Although the
occurrence of POAF was not significantly different among treatment and
control groups in patients with vitD insufficiency (31% vs.
33% P=0.538), there was a significant difference between
the two groups regarding to POAF in patients with vitD deficiency (18%
vs. 29% P=0.02). Conclusion Although preoperative vitD supplementation was not found to be associated
with prevention of POAF in patients with vitD insufficiency, it was found to
be strongly associated with prevention of POAF in those with vitD
deficiency.

Abstract
BACKGROUND Recent research suggests that abnormal Ca2+ handling plays a role in the occurrence and maintenance of atrial fibrillation (AF). Therefore, Ca2+ release and ingestion depend on properties of the ryanodine receptor (RyR) and sarcoplasmic reticulum Ca2+ATPase2a (SERCA2a). This study aimed to detect whether SERCA2a gene overexpression has a preventive effect on atrial fibrillation caused by rapid pacing right atrium. MATERIAL AND METHODS Forty-eight New Zealand white rabbits were randomly divided into a control group, AF group, AAV9/GFP group, and AAV9/SERCA2a group. The right atrium was rapidly paced at 600 beats/min for 30 days after an intraperitoneal injection of an adeno-associated virus expressing the SERCA2a gene and GFP. The AF induction rate and the effective refraction period (ERP) were measured after 0, 4, 8, 12, and 24 h of pacing. Western blot analysis was used to test for the expression of SERCA2a. Changes in atrial tissue structure were observed by H&E staining and electron microscopy. RESULTS The AF induction rate was higher in the AF groups than in the AAV9/SERCA2a group at different time points of pacing. After 12 h of pacing, ERP was significantly prolonged in the AAV9/SERCA2a group compared to the AF and AAV9/GFP groups (p<0.05). SERCA2a protein expression was significantly lower in the AF and AAV9/GFP groups compared to the control group (p<0.05), while expression was significantly higher in the AAV9/SERCA2a group than in the AF and AAV9/GFP groups (p<0.05). The myocardial structure of the AAV9/SERCA2a group was significantly improved compared with the AF group, indicating that SERCA2a overexpression relieved the structural remodeling of atrial fibrillation. CONCLUSIONS SERCA2a overexpression is capable of suppressing ERP shortening and AF induced by rapid pacing atrium. SERCA2a gene therapy is expected to be a new anti-atrial fibrillation strategy.

Abstract
Background Atrial fibrillation (AF) is one of the most critical and frequent arrhythmias precipitating morbidities and mortalities. The complete blood count (CBC) test is an important blood test in clinical practice and is routinely used in the workup of cardiovascular diseases. This systematic review with meta-analysis aimed to determine the strength of evidence for evaluating the association of hematological parameters in the CBC test with new-onset and recurrent AF. Material/Methods We conducted a meta-analysis of observational studies evaluating hematologic parameters in patients with new-onset AF and recurrent AF. A comprehensive subgroup analysis was performed to explore potential sources of heterogeneity. Results The literature search of all major databases retrieved 2150 studies. After screening, 70 studies were analyzed in the meta-analysis on new-onset AF and 23 studies on recurrent AF. Pooled analysis on new-onset AF showed platelet count (PC) (weighted mean difference (WMD)=WMD of −26.39×109/L and p<0.001), mean platelet volume (MPV) (WMD=0.42 FL and p<0.001), white blood cell (WBC) (WMD=−0.005×109/L and p=0.83), neutrophil to lymphocyte ratio (NLR) (WMD=0.89 and p<0.001), and red blood cell distribution width (RDW) (WMD=0.61% and p<0.001) as associated factors. Pooled analysis on recurrent AF revealed PC (WMD=−2.71×109/L and p=0.59), WBC (WMD=0.20×109/L (95% CI: 0.08 to 0.32; p=0.002), NLR (WMD=0.37 and p<0.001), and RDW (WMD=0.28% and p<0.001). Conclusions Hematological parameters have significant ability to predict occurrence and recurrence of AF. Therefore, emphasizing the potential predictive role of hematological parameters for new-onset and recurrent AF, we recommend adding the CBC test to the diagnostic modalities of AF in clinical practice.
