Abstract
Background Ischemic stroke is a common type of stroke that leads to death and functional disability in hypertensive patients. However, there are no well-studied non-invasive and less expensive fluid biomarkers routinely used to detect ischemic stroke in hypertensive patients. Hence, this study aimed to tease out the performance of D-dimer, fibrinogen, and the D-dimer to fibrinogen ratio (DDFR) in predicting hypertension-associated acute ischemic stroke. Methods A hospital-based cross-sectional study was done from October 2022 to January 2022 at Yikatit 12 Hospital Medical College, Ethiopia. We recruited 55 hypertensive patients who had an ischemic stroke and 110 who did not. A ROC curve was used to calculate the areas under the curves (AUCs) and determine the diagnostic power of the D-dimer, fibrinogen, and DDFR. The Youden index was used to find the best cut-off points for biomarkers in detecting acute ischemic stroke. A De Long test was employed to show whether there was a significant difference between the AUCs of biomarkers in diagnosing ischemic stroke. Results D-dimer yielded the highest diagnostic power (AUC = 0.776) in detecting acute ischemic stroke, followed by DDFR (AUC = 0.763) and fibrinogen (AUC = 0.694), but there was no significant difference between them. At 0.52 μg/ml cut-off point, D-dimer had 82.9% sensitivity, 66.7% specificity, 62.5% PPV, and 85.3% NPV to diagnose acute ischemic stroke. Fibrinogen could detect acute ischemic stroke at 405.85 mg/dl level, with 70.0% sensitivity, 57.1% specificity, 41.2% PPV and 81.6% NPV. At a 1.83 ratio, DDFR might also identify ischemic stroke with 80.0% sensitivity, 67.1% specificity, 51.1% PPV, and 88.7% NPV. Conclusion We showed D-dimer, fibrinogen, and DDFR as promising, affordable, and non-invasive biomarkers for the detection of ischemic stroke among subjects with hypertension. This will help clinicians make an early diagnosis and better guide patient therapy.

Abstract
D-dimer and fibrinogen are nonspecific diagnostic biomarkers for venous thromboembolism (VTE). The aim of this article was to present the values of D-dimer and fibrinogen in relation to the anatomical localization of deep vein thrombosis (DVT). This was an observational study, which included 1,142 patients hospitalized from 2010 to 2019 at the Department of Angiology, Clinical Center University of Sarajevo. Data on gender, age, and thrombosis location were collected of all patients. Fibrinogen and D-dimer values were available for 983 and 500 patients, respectively. Thrombosis location was classified as iliofemoral (521-45.6% patients), femoral-popliteal (486-42.6% patients), isolated calf DVT (63-5.5% patients), and upper extremity DVT (UEDVT in 72-6.3% patients). A majority, 448 (89.6%), of patients had high D-dimer (the cutoff is 0.55 mg/L) and 662 (67.3%) patients had high fibrinogen (reference range: 1.8-3.8 g/L). The highest D-dimer was detected in patients with iliofemoral DVT (mean: 10.48 mg/L), χ2 = 50.78, p = 0.00. The highest fibrinogen was detected in patients with iliofemoral DVT as well (mean 4.87 g/L), χ2 = 11.1, p = 0.01. D-dimer and fibrinogen values are significantly higher in patients iliofemoral DVT than femoral-popliteal and isolated calf DVT, and D-dimer values are significantly higher in lower extremity DVT than UEDVT, but these biomarkers cannot be used alone to discriminate between thrombosis locations. Further imaging is required.

D-dimer to fibrinogen ratio predicts early neurological deterioration in ischemic stroke with atrial fibrillation. Thromb Res 2023; 229:219-224. [PMID: 37562164 DOI: 10.1016/j.thromres.2023.07.014] [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: 03/01/2023] [Revised: 07/19/2023] [Accepted: 07/28/2023] [Indexed: 08/12/2023]
Abstract
INTRODUCTION The D-dimer to fibrinogen ratio (DFR) is a good indicator of clot-producing activity in thrombotic disease, but its clinical usefulness in stroke patients with nonvalvular atrial fibrillation (NVAF) has not been studied. We evaluated the association between the DFR and early neurological deterioration (END) in acute ischemic stroke (AIS) patients with NVAF. METHODS We included consecutive AIS patients with NVAF between 2013 and 2015 from the registry of a real-world prospective cohort from 11 large centers in South Korea. END was defined as an increase ≥2 in the total NIHSS score or ≥ 1 in the motor NIHSS score within the first 72 h of admission. The DFR was calculated as follows: DFR = D-dimer (mg/L)/fibrinogen (mg/dL) x 100. RESULTS A total of 1018 AIS patients with NVAF were evaluated. In multivariable logistic regression analysis, the highest DFR tertile was closely associated with END (adjusted odds ratio [aOR] = 2.14, 95 % confidence interval [CI]: 1.24-3.69). Hypertension (aOR = 1.71, 95 % CI: 1.09-2.70), initial NIHSS score (aOR = 1.05, 95 % CI: 1.02-1.07) and use of anticoagulants (aOR = 0.41, 95 % CI: 0.28-0.60) were also correlated with END. In addition to END, the DFR was correlated with discharge NIHSS and modified Rankin Scale (mRS) scores and the 3-month mRS score. CONCLUSIONS High DFR values were associated with END in AIS patients with NVAF. As the DFR is an indicator directly related to the main pathological mechanism of NVAF patients (fibrinolysis and coagulation), it may be useful in predicting their prognosis.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES To evaluate the predictive value of D-dimer/fibrinogen (D/F) ratio for deep vein thrombosis (DVT) in patients with traumatic spinal cord injury (SCI). SETTING Department of Rehabilitation Medicine Center, West China Hospital, Sichuan University. METHODS SCI patients within 24 h of trauma were consecutively enrolled. DVT was diagnosed by DUS examination during hospitalization. Multivariable logistic regression analysis was performed to determine the relationship between D/F ratio and DVT. Stratified logistic regression analysis was performed to identify effect modifiers. The receiver operating characteristic (ROC) curve was conducted to assess the predictive value of D/F ratio. RESULTS A total of 284 patients with SCI were included, of whom 106 (37.3%) developed DVT. D/F ratio was positively correlated with DVT (OR 1.17, 95% confidence interval [CI] 1.04-1.31, p = 0.009). Patients in the upper D/F ratio tertile (3.15-18.27) had a higher risk of DVT than patients in the lower tertile (0.08-0.97) after adjustment for potential confounders (OR 6.01, 95% CI 2.24-16.15, p < 0.001). The risk of DVT increased stepwise across D/F ratio tertiles (p for trend = 0.003). The area under the ROC curve (AUC) was 0.758 (95% CI 0.704-0.806). There was a significant interaction between D/F ratio and neurological level of injury (p for interaction = 0.003) and the association between D/F ratio and DVT remained significant only in patients with cervical injury. CONCLUSIONS A higher D/F ratio was independently associated with a higher risk of DVT in a dose-dependent manner in patients with cervical SCI.

Using an age and fibrinogen levels adjusted D-dimer cutoff significantly improves the specificity of two equivalent D-dimer assays for excluding pulmonary embolism. Thromb Res 2023; 228:191-199.

Abstract
OBJECTIVES Our single-center prospective study compared two methods of D-dimer determination used in the exclusion of pulmonary embolism: bioMérieux method, VIDAS® D-Dimer Exclusion™ II, and Diagnostica Stago method, STA®-Liatest® D-Di Plus. For each of these two methods, we calculated optimized variable cutoffs based on fibrinogen and/or age to improve the specificity of the methods. PATIENTS - METHODS 2530 patients admitted to the Emergency Department of the Brest University Hospital for suspected pulmonary embolism were included in this study. The comparison of the two methods was performed by calculating their different characteristics: sensitivity, specificity and negative predictive value for different cutoffs systems: fixed or age-adjusted according to Douma et al. An optimization of the variable cutoff according to age and fibrinogen was then performed. RESULTS The two methods VIDAS and STAGO are approximately equivalent in terms of performance even if the STAGO method presents a better specificity (57.1 %) at the fixed cutoff of 0.5 μg/mL. The adoption of age-adjusted, fibrinogen-adjusted or doubly-adjusted (age and fibrinogen) cutoffs, significantly improves the specificity of the tests without affecting their excellent sensitivity. These specificities peak respectively at 75.8 % and 76 % for the VIDAS and STAGO tests when using a doubly-adjusted, age and fibrinogen, cutoff, i.e. a gain in specificity of approximately 10 % compared with the age-adjusted cutoff of Douma et al. and of approximately 20 % compared with the fixed cutoff of 0.5 μg/mL. CONCLUSION Adopting an optimized variable cutoff based on fibrinogen and/or age significantly improves specificity of D-dimer methods for pulmonary embolism exclusion.

Abstract
Background This study aimed to investigate the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and D-dimer-to-fibrinogen ratio (DFR) as predictors of pneumonia and poor outcomes in patients with acute intracerebral hemorrhage (ICH). Methods We retrospectively examined patients with acute ICH treated in our institution from May 2018 to July 2020. Patient characteristics, laboratory testing data, radiologic imaging data, and 90-day outcomes were recorded and analyzed. Results Among the 329 patients included for analysis, 183 (55.6%) developed pneumonia. Systolic blood pressure, initial hematoma volume, D-dimer concentration, NLR, PLR, DFR, and white blood cell, platelet, neutrophil, and lymphocyte counts at admission were significantly higher in patients who developed pneumonia than in those who did not; however, the Glasgow coma scale (GCS) score at admission was significantly lower in pneumonia patients compared with non-pneumonia patients (all P <0.05). Multivariate logistic regression showed that the NLR and PLR were independent predictors of pneumonia, and the NLR and DFR were independent predictors of poor 90-day outcomes (modified Rankin scale score 4–6). Conclusion The NLR and PLR were independent predictors of pneumonia and the NLR and DFR were independent predictors of poor 90-day outcomes. The NLR, PLR, and DFR can provide prognostic information about acute ICH patients.

Abstract
BACKGROUND D-Dimer and fibrinogen were commonly used to detect the coagulation and fibrinolytic function, but D-dimer to fibrinogen ratio (DFR) in carotid plaque in young patients aged 18-45 with acute cerebral infarction (ACI) has not been used clinically. In this work, we focused on the evaluation of the DFR value of this group of patients and analyzed its possible correlation. METHODS A total of 164 patients with ACI patients aged 18-45 were selected as research subjects after their first admission. They had undergone carotid plaque contrast-enhanced ultrasound (CEUS) and were divided into two groups with carotid plaque (n = 97) and with no carotid plaque (n = 67). According to NIHSS score and carotid plaque grade, the clinical symptoms of patients were judged. Univariate and multivariate analyses were conducted to compare the risk factors of carotid plaque in ACI patients. RESULTS The DFR value of patients in the carotid plaque group (103.41 ± 20.81) was significantly higher than that of the no carotid plaque control group (88.9 ± 26.51). We also identified DFR X103 was the only independent risk factor (β = 0.53; 95% CI, 0.914-0.984; P = 0.05). DFR X103 was increased with the severity of the disorder and with the CEUS grades. The area under the DFR curve was 0.673 (95% CI 0.584~0.762). CONCLUSION The value of the DFR is positively correlated with CEUS carotid plaque grading and NIHSS score, which can predict the severity of carotid plaque in ACI patients aged 18-45. Therefore it is worthy of clinical application.

Abstract
Abnormal coagulation parameters are often observed in patients with coronavirus disease 2019 (COVID-19) and the severity of derangement has been associated with a poor prognosis. The COVID-19 associated coagulopathy (CAC) displays unique features that include a high risk of developing thromboembolic complications. Viscoelastic tests (VETs), such as thromboelastometry (ROTEM), thromboelastography (TEG) and Quantra Hemostasis Analyzer (Quantra), provide "dynamic" data on clot formation and dissolution; they are used in different critical care settings, both in hemorrhagic and in thrombotic conditions. In patients with severe COVID-19 infection VETs can supply to clinicians more information about the CAC, identifying the presence of hypercoagulable and hypofibrinolysis states. In the last year, many studies have proposed to explain the underlying characteristics of CAC; however, there remain many unanswered questions. We tried to address some of the important queries about CAC through VETs analysis.

Marcianò T, Franchini S. Could a D-dimer/fibrinogen ratio have a role in ruling-out venous thromboembolism? Emerg Med J 2021; 39:941-944. [PMID: 34493596 DOI: 10.1136/emermed-2020-210688] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Accepted: 08/23/2021] [Indexed: 11/04/2022]
Abstract
BACKGROUND Diagnosis of venous thromboembolism (VTE) requires chest CT angiography for pulmonary embolism and venous ultrasound for deep vein thrombosis. To reduce imaging, guidelines recommend D-dimer levels to rule-out VTE in patients with a low pre-test probability. The most widely used D-dimer cut-off is 500 ng/mL. This cut-off has low specificity, meaning many patients without disease require imaging. METHODS In this retrospective chart review, we evaluated the diagnostic performance of the D-dimer/fibrinogen ratio (DFR) for identifying thromboembolism and compared it to the performance of two different D-dimer cut-offs (500 ng/mL and 1000 ng/mL) in patients who underwent a chest CT angiography or a venous ultrasound in the ED of San Raffaele Hospital, Italy, in 2017. Patients had a retrospective Wells score calculated after chart review, identifying both high-risk and low-risk pre-test probability patients for this study and low probability patients were further stratified into low-risk of deep vein thrombosis or pulmonary embolism. RESULTS Enrolled patients included 92 with suspected pulmonary embolism and 154 with suspected deep vein thrombosis; of whom 67 (27%) were diagnosed with VTE. The most accurate cut-off for DFR in terms of discriminative power was 2.65. In the whole sample and in low-risk patients, this cut-off had the same sensitivity values of the 500 ng/mL D-dimer cut-off (97% (95% CI: 89.8% to 99.2%)), while slightly lower sensitivity values were found for the 1000 ng/mL D-dimer cut-off (95.5% (95% CI: 87.6% to 98.5%)). Specificity was higher for the 2.65 DFR cut-off (55.3% (95% CI: 48.0% to 62.4%)) in the whole sample compared with both 500 ng/mL D-dimer cut-off (22.9% (95% CI: 17.4% to 29.6%)) and 1000 ng/mL D-dimer cut-off (45.8% (95% CI: 38.7% to 53.1%)). Similar results were found in all subgroups. CONCLUSION A DFR, with a cut-off of 2.65, may improve the specificity for VTE patients when compared with D-dimer alone in high-risk VTE emergency medicine populations. This is exploratory information only, needing evaluation in prospective, multicentre studies, prior to consideration for use in routine clinical work.

Abstract
OBJECTIVE To study the predictive effect on YCH patients complicated with LEDVT by PLR and DFR combined with WELLS score. MATERIALS AND METHODS A total of 109 patients with YCH were selected as the research subjects. Patients with combined LEDVT were in the thrombosis group (33 cases), and without LEDVT in the non-thrombosis group (76 cases). Wells score was used to evaluate the vascular of the lower extremities. The PLR and DFR were calculated. The diagnostic value of PLR and DFR combined with the Wells score was evaluated by the AUC, sensitivity, specificity, and other indicators in the ROC. RESULTS The values of PLR, DFR, and Wells score in the thrombus group were 149.20 ± 52.17, 118.46 ± 8.37, and 2.67 ± 0.48, and that of the non-thrombotic group were 95.27 ± 29.48, 75.28 ± 10.16, and 0.72 ± 0.34, respectively. The differences were statistically significant. ROC results showed good diagnosis power of PLR (sensitivity 86.35%, specificity 75.18%, AUC 0.702.), DFR (sensitivity 88.57%, specificity 79.21%, AUC 0.786.), and the Wells score (sensitivity 90.17%, specificity 81.06%, AUC 0.889.). The combined application of the Wells score, PLR, and DFR for the occurrence of LEDVT had a sensitivity of 97.65%, a specificity of 92.43%, a missed diagnosis rate of 2.35%, and a misdiagnosis rate of 7.57%. The area under the ROC curve was 0.951, which was higher than using these variables independently. CONCLUSIONS PLR and DFR combined with Wells score have high specificity for predicting LEDVT in YCH patients with low missed diagnosis and low misdiagnosis rates. They are worthy of popularization and application.

Abstract
Fourty-five breast cancer patients and 50 apparently healthy sex-matched controls from the University of Ilorin Teaching Hospital were enrolled in this study. Plasma D-dimer and fibrinogen were found to be significantly higher than controls; APTT was significantly shorter than the controls. D-dimer and fibrinogen were also significantly positively correlated with ECOG, disease stage, lymph node involvement, and tumor size. On multivariate analysis, D-dimer and fibrinogen were found to be independently related to lymph node involvement. This study shows that plasma D-dimer and fibrinogen levels are elevated in breast cancer patients, and both are markers of disease progression.

Abstract
INTRODUCTION Due to the high mortality of coronavirus disease 2019 (COVID-19), there are difficulties in the managing emergency department. We investigated whether the D-dimer/albumin ratio (DAR) and fibrinogen/albumin ratio (FAR) predict mortality in the COVID-19 patients. METHODS A total of 717 COVID-19 patients who were brought to the emergency department from March to October 2020 were included in the study. Levels of D-dimer, fibrinogen and albumin, as well as DAR, FAR, age, gender and in-hospital mortality status of the patients, were recorded. The patients were grouped by in-hospital mortality. Statistical comparison was conducted between the groups. RESULTS Of the patients included in the study, 371 (51.7%) were male, and their median age was 64 years (50-74). There was in-hospital mortality in 126 (17.6%) patients. The area under the curve (AUC) and odds ratio values obtained by DAR to predict in-hospital mortality were higher than the values obtained by the all other parameters (AUC of DAR, albumin, D-dimer, FAR and fibrinogen: 0.773, 0.766, 0.757, 0.703 and 0.637, respectively; odds ratio of DAR > 56.36, albumin < 4.015, D-dimer > 292.5, FAR > 112.33 and fibrinogen > 423:7.898, 6.216, 6.058, 4.437 and 2.794, respectively). In addition; patients with concurrent DAR > 56.36 and FAR > 112.33 had an odds ratio of 21.879 with respect to patients with concurrent DAR < 56.36 and FAR < 112.33. CONCLUSION DAR may be used as a new marker to predict mortality in COVID-19 patients. In addition, the concurrent high DARs and FARs were found to be more valuable in predicting in-hospital mortality than either separately.

Abstract
The role of activation of the coagulation and fibrinolysis system in the pathogenesis and prognosis of cardiovascular diseases (CVDs) has drawn wide attention. Recently, the D-dimer to fibrinogen ratio (DFR) is considered as a useful biomarker for the diagnosis and prognosis of ischemic stroke and pulmonary embolism. However, few studies have explored the relationship between DFR and cardiovascular disease. In our study, patients were divided into 2 groups according to DFR value: the lower group (DFR < 0.52, n = 2123) and the higher group (DFR ≥ 0.52, n = 1073). The primary outcome was all-cause mortality (ACM) and cardiac mortality (CM). The average follow-up time was 37.59 ± 22.24 months. We found that there were significant differences between the 2 groups in term of ACM (2.4% vs 6.6%, P < 0.001) and CM (1.5% vs 4.0%, P < 0.001). Kaplan-Meier analyses showed that elevated DFR had higher incidences of ACM (log rank P < 0.001) and CM (log rank P < 0.001). Multivariate Cox regression analyses showed that DFR was an independent predictor of ACM (HR = 1.743, 95%CI: 1.187-2.559 P = 0.005) and CM (HR = 1.695, 95%CI: 1.033-2.781 P = 0.037). This study indicates that DFR is an independent and novel predictor of long-term ACM and CM in post-PCI patients with CAD.

Abstract
Aim: To evaluate the clinical value of plasma D-dimer/fibrinogen ratio (DFR) in patients hospitalized for heart failure (HF). Methods: Clinical data of 235 patients were retrospectively analyzed. Kaplan-Meier method and Cox regression analysis were used to identify significant prognosticators. Results: The Kaplan-Meier analysis showed that a higher DFR level was significantly associated with an increase in the end point outcomes, including HF readmission, thrombotic events and death (log-rank test: p < 0.001). The multivariate Cox regression analysis showed that the high tertile of DFR was significantly associated with the study end points (HR: 2.18; 95% CI: 1.31-3.62; p = 0.003), compared with the low tertile. Conclusion: DFR is a reliable prognostic indicator for patients hospitalized for HF.

Abstract
INTRODUCTION AND OBJECTIVE At present, there is no hematology marker with high specificity to the diagnosis and differential diagnosis of acute ischemic stroke (AIS). How to use the existing test items to improve the diagnosis efficiency worthy of discussion. D-Dimer (DD) and fibrinogen (FIB) were the common indicators in thrombotic diseases, but D-dimer to fibrinogen ratio (D/F) in AIS has not been used in clinical practice. In this work, we focus on the evaluation of D/F. METHODS 90 AIS patients were selected as the observation group and 65 other patients without coagulation function disorder as the control group. Meanwhile, a total of 33 patients with other diseases with impaired consciousness in the same period were collected. Based on the AIS patients with or without consciousness disorder divided it into consciousness disorder group and unconsciousness disorder group. Then based on the patients with or without consciousness disorder divided it into other diseases with unconsciousness disorder group and Other diseases with lacunar cerebral infarction (LCI)and disturbance of consciousness group. then compare the differences of plasma DD, FIB and D/F between groups. RESULTS All plasma DD, FIB and D/F ratio in AIS patients were significantly higher than in other disease group (P = 0.000, P = 0.001, P = 0.000), but DD, D/F in disorders of consciousness group was significantly higher than in unconsciousness disorders group (P = 0.007, P = 0.005). The DD of the AIS with consciousness disorder group were significantly higher than that of the other disease with consciousness disorder group (P = 0.042), and the DD, D/F ratio of Other diseases with lacunar cerebral infarction and disturbance of consciousness group were significantly higher than one(P = 0.000, P = 0.003). All others are undifferentiated. CONCLUSIONS When DD, D/F ratio is high, other diseases caused by consciousness disorders are likely to be combined with infarcts, which can be used for the diagnosis and differential diagnosis of patients with different types of consciousness disorders, especially hospitalized patients.

D-dimer/fibrinogen ratio for the prediction of progressive hemorrhagic injury after traumatic brain injury. Clin Chim Acta 2020; 507:143-148. [PMID: 32333859 DOI: 10.1016/j.cca.2020.04.022] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Revised: 04/18/2020] [Accepted: 04/21/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Progressive hemorrhagic injury (PHI) greatly affects prognosis of traumatic brain injury (TBI). D-dimer/fibrinogen ratio (D/F ratio) may be a potential predictor for venous thromboembolism. This study sought to describe and evaluate any relationship between D/F ratio and PHI after TBI. METHODS This retrospective study included a cohort of 192 TBI patients. Plasma D-dimer and fibrinogen were measured, and subsequently D/F ratio was calculated. Multivariate logistic regression analysis was applied to identify predictors of PHI. Receiver operating characteristic (ROC) curve was conFig.d to analyze predictive capability for PHI. RESULTS A total of 43 patients (22.4%) experienced PHI. Both Glasgow coma scale (GCS) score (odds ratio [OR], 0.565; 95% CI, 0.464-0.689) and D/F ratio (OR, 4.026; 95% CI, 2.219-7.305) were the two independent predictor for PHI. Area under ROC curve (AUC) of D/F ratio was similar to that of GCS score (AUC, 0.816; 95% CI, 0.754-0.868 vs. AUC, 0.834; 95% CI, 0.773-0.883; P = 0.699). Moreover, D/F ratio significantly improved AUC of GCS score to 0.928 (95% CI, 0.881-0.960; P < 0.001). CONCLUSIONS D/F ratio was strongly predictive of PHI in the studied cohort and, thereby should be considered in the clinical management of TBI patients.

Abstract
OBJECTIVE Previous studies show that serum fibrinogen levels are established risk factors for coronary artery disease (CAD) and that serum albumin levels are of a higher specificity and sensitivity in ST-elevation myocardial infarction (STEMI). In this study, we sought to evaluate the association between fibrinogen to albumin ratio (FAR) and the extent and severity of CAD evaluated by TAXUS Drug-Eluting Stent Versus Coronary Artery Bypass Surgery for the Treatment of Narrowed Arteries (SYNTAX) Score (SS) in patients with STEMI. METHODS A total of 278 patients with STEMI were included in the study. FAR was calculated using specified variables. The extent and severity of CAD were evaluated using the SS. The patients were divided into low- (SS <22) and high- (SS ≥22) risk groups. A Spearman rank correlation coefficient analysis was used for the relationship between FAR and SS. The cutoff points for sensitivity and specificity of FAR in predicting SS were estimated by performing a receiver operator characteristic curve analysis. RESULTS There were significant differences in the mean age (P=.016), admission serum albumin (P=.041), serum fibrinogen (P<.001), FAR (P<.001), and SS risk groups. Positive correlation was detected between FAR and SS (r=0.458, P<.001). A cutoff level of >87 FAR predicted SS (sensitivity, 70%; specificity, 70%), and an area under the curve of 0.758 serum fibrinogen and albumin level was an independent predictor for SS in patients with STEMI (b=0.039; 95% confidence interval, 0.016-0.062; P=.001 and b=-6.906; 95% confidence interval, -12.284 to -1.527; P=.013, respectively). CONCLUSION In the present study, we showed that FAR is significantly related to SS in predicting the severity of CAD in patients with STEMI.

Abstract
OBJECTIVES The D-dimer level, fibrinogen level, and D-dimer/fibrinogen ratio are used in the diagnosis of pulmonary embolism, but results vary. We evaluated these parameters in the diagnosis of pulmonary embolism in emergency clinic patients. METHODS In this prospective study, 200 patients (pulmonary embolism, 100 patients; no pulmonary embolism, 100 patients) had D-dimer and fibrinogen levels measured before intervention. Pulmonary embolism was diagnosed with computed tomography angiography or ventilation-perfusion scintigraphy. RESULTS Compared with patients who did not have pulmonary embolism, patients who had pulmonary embolism had significantly greater mean D-dimer level (pulmonary embolism, 6±7 μg/ml; no pulmonary embolism, 1±1 μg/ml; P⩽0·001) and D-dimer/fibrinogen ratio (pulmonary embolism, 3±3; no pulmonary embolism, 0·4±0·4; P⩽0·001), but similar mean fibrinogen levels (pulmonary embolism, 337±184 mg/dl; no pulmonary embolism, 384±200 mg/dl; not significant). In patients who had pulmonary embolism, mean D-dimer level and D-dimer/fibrinogen ratio were greater in high-risk than non-high-risk patients. With D-dimer cutoff 0·35 μg/ml, sensitivity was high (100%) and specificity was low (27%) for pulmonary embolism. With D-dimer/fibrinogen ratio cutoff 0·13, sensitivity was high (100%) and specificity was low (37%) for pulmonary embolism. CONCLUSION A D-dimer level <0·35 μg/ml may exclude the diagnosis of pulmonary embolism. At a D-dimer cutoff 0·5 μg/ml and D-dimer/fibrinogen ratio cutoff 1·0, the D-dimer/fibrinogen ratio may have better specificity than D-dimer level in the diagnosis of pulmonary embolism, but the D-dimer/fibrinogen ratio may lack sufficient specificity in screening.

Abstract
INTRODUCTION Normal pregnancy is associated with hypercoagulable state. Elevated markers of coagulation and fibrinolytic system activation indicate increased thrombin activity and increased fibrinolysis following fibrin formation throughout pregnancy. These changes exceed the biological variability in most cases. Haemostatic reference intervals are generally based on samples from non-pregnant women. Thus, they may not be relevant to pregnant women, a problem that may hinder accurate diagnosis and treatment of haemostatic disorders during pregnancy. The aim of the study was to follow the changes of haemostatic parameters and to establish gestational age-specific reference intervals during normal pregnancy. MATERIALS AND METHODS Blood samples of 83 pregnant women were collected at gestational weeks 16, 26 and 36. Fibrinogen, D-dimer, and C-Reactive Protein (CRP) were examined. Reference intervals were calculated for fibrinogen, D-dimer tests with two different methods (mean±2 SD or median and 2.5th and 97.5th percentiles with 90% confidence intervals). RESULTS fibrinogen and D-dimer increased progressively throughout pregnancy. Mean fibrinogen levels were higher than the maximum of the conventional reference interval, already in the 16th week of pregnancy. D-dimer levels were at or above the conventional cutoff point (250ng/mL) throughout the pregnancy in 42% of pregnant women, while in the 36th week 98% of them displayed elevated D-dimer levels. CRP did not increase in normal pregnancy. CONCLUSIONS There seems to be an emerging need to reconsider fibrinogen and D-dimer values from a different aspect in pregnancy compared to non-pregnant reference intervals. New reference ranges are suggested to be established in pregnancy.

Abstract
Reduced concentration of tissue factor pathway inhibitor is a risk factor for development of deep venous thrombosis, whereas elevated concentrations of tissue factor pathway inhibitor are observed in patients with acute myocardial infarction and disseminated intravascular coagulation. Presently, we studied the association between inflammation, endothelial cell perturbation, fibrin degradation and the concentration of tissue factor pathway inhibitor in patients suspected for acute deep venous thrombosis. We determined the tissue factor pathway inhibitor -33T/C polymorphism, free and total tissue factor pathway inhibitor, C-reactive protein, von Willebrand factor and D-Dimer in 160 consecutive patients admitted to hospital with a tentative diagnosis of acute deep venous thrombosis. Deep venous thrombosis was identified in 57 patients (18 distal and 39 proximal). The distribution of the tissue factor pathway inhibitor genotypes between patients with and without deep venous thrombosis showed a trend toward significant deviation (P = 0.08). The concentrations of free and total tissue factor pathway inhibitor, C-reactive protein, von Willebrand factor and D-Dimer were significantly higher in patients with deep venous thrombosis than in patients without deep venous thrombosis (P < 0.001 for all quantities). The significant relationship between free and total tissue factor pathway inhibitor and deep venous thrombosis persisted when adjusted for the tissue factor pathway inhibitor -33T/C polymorphism, C-reactive protein, von Willebrand Factor and potentially confounding clinical conditions (P < or = 0.004), but disappeared when adjusted for D-Dimer (P > or = 0.10). We conclude that patients suffering from acute deep venous thrombosis express significantly higher concentrations of tissue factor pathway inhibitor than patients without deep venous thrombosis. The significant relationship is not associated with the -33T/C polymorphism, inflammation or endothelial cell perturbation, but is most likely related to release of tissue factor pathway inhibitor from fibrin deposits.
