    ABSTRACT: Interaction between cigarette smoking and efficacy of oral antiplatelet drugs is not definitely elucidated. We evaluated the effects of cigarette smoking on platelet reactivity in patients receiving different oral P2Y12 antagonists after myocardial infarction (MI) and drug-eluting stent (DES) implantation. Two-hundred-five consecutive current smokers receiving DES implantation after ST-segment elevation MI were enrolled. All patients were aspirin-treated and were on chronic therapy with clopidogrel (N = 59), prasugrel (N = 71) or ticagrelor (N = 75); by protocol, all patients at baseline had no high on-treatment platelet reactivity by the VerifyNow P2Y12 assay. Platelet reactivity, expressed by P2Y12 reaction units (PRU), was measured in all patients at baseline (T0), after a 15-day period of smoking cessation (T1) and after further 15 days of smoking resumption (T2). In the overall population there was a modest, albeit significant, reduction of PRU values from T0 to T1 (from 173 ± 14 to 165 ± 17, P < 0.0001); resumption of cigarette smoking was associated with re-increase of platelet reactivity (from 165 ± 17 at T1 to 170 ± 17 at T2, P = 0.0002). These variations were consistent in the subgroups receiving clopidogrel, prasugrel or ticagrelor and were irrespective of the number of cigarettes smoked. In conclusion, cigarette smoking weakly influences antiplatelet effects of oral P2Y12 inhibition and this was irrespective of the type of antiplatelet agent; thus, interaction between cigarette smoking and efficacy of oral antiplatelet drugs is modest and unlikely translates into clinical effects ( Identifier: NCT02026713).

    ABSTRACT: Microplasminogen (μPlg), a truncated form of human plasminogen, has considerable potential as a direct-acting thrombolytic agent. To further develop μPlg into a thrombolytic agent with anti-thrombus properties, we constructed two μPlg variants containing tripeptide Arg-Gly-Asp (RGD) and tetrapeptide Gly-Pro-Arg-Pro (GPRP) by site-directed mutagenesis. The recombinant cDNAs were expressed in yeast (Pichia pastoris) and purified to high homogeneity by Ni-NTA affinity chromatography. The specific activities of RGD-μPlg and GPRP-μPlg were 7.7 and 13.3 U/mg, respectively, as determined using the fibrin-plate method. RGD-μPlg significantly inhibited ADP-induced platelet aggregation, which was 33.6- and 14.1-fold higher than the native μPlg and GPRP-μPlg, respectively. On the other hand, GPRP-μPlg prolonged thrombin-initialized fibrinogen polymerization in a concentration-dependent manner, which was 9.2- and 5.7-fold stronger than μPlg and RGD-μPlg, respectively. Under activation by urokinase, μPlg, RGD-μPlg, and GPRP-μPlg all showed over 80 % conversions to their active enzyme in 24 h. The structure models that docked RGD-μPlg and μPlg activation loops into the enzymatic active site of urokinase showed that Pro559 to Asp559 mutation of RGD-μPlg led to an alteration in the interaction, which possibly explains the slowed activation of RGD-μPlg by urokinase over an 80-min period. In conclusion, this study has presented two recombinant μPlg variants with anti-platelet aggregation and anti-fibrinogen clotting activity, thus suggesting the anti-thrombosis properties of these two μPlg derivatives.

    ABSTRACT: Specific therapy of acute spinal ischemia is not established. We report the first case of an MRI-verified cervical spinal ischemia treated by thrombolysis and review the literature. A 72-year old woman with right-sided motor hemiparesis and trunk ataxia was treated by intravenous thrombolysis with full recovery. Three days later she developed again a severe right-sided sensorimotor hemiparesis and a second off-label intravenous thrombolysis was repeated. Magnetic resonance imaging revealed a right-sided posterior-lateral cervical spinal ischemia. Spinal ischemia may clinically present with a cerebral-stroke-like picture challenging diagnostic and therapeutic procedure. Systemic thrombolysis might be a treatment option in acute spinal ischemia. In addition, early repeated systemic thrombolysis may be considered in selected strokes.

    ABSTRACT: To describe an on-table modification of standard angiography catheters for use in directed arterial and venous thrombolysis. An angiogram is performed and the length of thrombosed vessel (artery or vein) is measured. A 5 or 6 Fr catheter (preferably straight/multi- purpose/vertebral catheter) is modified on table for use by making multiple holes with 23 G needle. After testing ex vivo with saline injection, the on table modified catheter is placed over a wire into the thrombosed segment of the vessel and thrombolytic agent infusion is commenced utilizing a syringe driver after giving a bolus dose of thrombolytic agent. Median duration of thrombolysis was 24 h in our study. We have utilized this method in twenty thrombosed vessels, without any catheter related complications. In our experience, this modification of a standard catheter as a multi-hole catheter is a readily available, simple, cheap, versatile and effective device for directed thrombolysis.

    ABSTRACT: Obese individuals, despite having increased cardiovascular (CV) risk factors experience adverse CV outcomes less frequently than non-obese. Little is known about association of long-term weight gain to development of coronary artery disease (CAD), inflammation and thrombogenicity. 418 consecutive patients with suspected CAD undergoing elective cardiac catheterization were included in a sub-analysis of the multi analyte, thrombogenic, and genetic markers of atherosclerosis study. Maximum weight gain (MWG) was defined as percentage increase in weight since age 17 years to year of heaviest weight and categorized as: minor (<30 %), moderate (30-47 %), severe (>47-69 %), and extreme (>69 %). Lipid profiling was determined by vertical density gradient ultracentrifugation, thrombin-induced platelet fibrin clot strength (TIP-FCS) by thrombelastography, and urinary 11-dehydrothromboxane B2 (11-dhTxB2) by ELISA. CAD severity was defined as minimal (<20 %), moderate (20-75 %), and severe (>75 %) luminal diameter obstruction of any major coronary vessel. The mean MWG was 53 ± 33 %. Extreme MWG group had a higher incidence of diabetes mellitus (48 %), hypertension (81 %), depression (25 %), and were most often female (60 %) (p < 0.05 for all). In women, CAD severity was inversely associated to MWG (p = 0.05), whereas in men no such association was observed (p = 0.18). TIP-FCS increased in a stepwise fashion with MWG (p = 0.001). 11-dTxB2 levels were higher in the extreme MWG group, regardless of lipid lowering therapy (p < 0.05). Our data suggest that maximal weight gain since age 17 years is associated with heightened thrombogenicity, inflammation and a poorer lipid profile but not an increased risk for severe CAD development.

    ABSTRACT: High residual platelet activation (HRPA) after ADP stimuli has associated with recurrent vascular events in acute atherothrombosis with the use of antiplatelet agents (APAs). However, there has been little evidence supporting this association in acute ischemic stroke (AIS). In this study, we evaluated the influences of HRPR after ADP stimuli on the 1-year incidence of recurrent cardiovascular events and mortality in AIS with APAs. We conducted an observational, referral center cohort study on 968 AIS patients with APAs from January 2010 to December 2013 who were evaluated using optical platelet aggregometry (OPA). All patients received the dual APA combination of aspirin and clopidogrel or aspirin alone. We evaluated their platelet function 5 days after hospital admission using OPA. HRPR after ADP stimuli was defined as platelet aggregation of 70 % or greater according to OPA after 10 µM ADP stimuli. The primary endpoint was a composite of all causes of death, myocardial infarction, and stroke at the 1-year follow-up. The secondary endpoints were each component of the primary endpoint. The event rate of primary endpoint was 11.3 % (109/968). Its rate was significantly higher in the patients with HRPR (16.7 %) than in those without (9.7 %). HPRP was independently associated with the primary endpoint (OR = 1.97, CI 1.22-3.18, p < 0.01). According to the AIS subtype, the presence of HRPR was independently significant for the occurrence of the primary endpoint in the large artery atherosclerosis (LAA) subtype only (OR = 2.26, CI 1.15-4.45, p = 0.02). In this study, the presence of HRPR after ADP stimuli is associated with a poor long-term outcome after acute ischemic stroke. In particular, the influence of this factor might be more prominent in LAA compared with other types of AIS.

    ABSTRACT: We present the case of a healthy, young Caucasian female who presented to an outside hospital with phlegmasia cerulea dolens of both lower extremities. Computed tomography angiography revealed inferior vena cava (IVC) occlusion. She was initiated on heparin infusion and transferred to University of Virginia Medical Center. Our evaluation revealed aplasia of the IVC from the infrahepatic segment to the confluence of the common iliac veins and acute bilateral iliac vein thromboses. An extensive network of collateral veins was noted. These findings were consistent with IVC agenesis. She was not pregnant or using contraception. Primary thrombophilia workup was negative. She underwent bilateral iliac vein thrombolysis and was started on anticoagulation. While IVC agenesis is rare, it carries risk for development of thrombotic sequelae and bears consideration when evaluating young patients with unexplained deep vein thrombosis, especially if extensive and bilateral.

    ABSTRACT: This study deciphered the molecular mechanisms of the inhibition of MMP-9 expression using rosuvastatin in cultured human umbilical vein endothelial cells (HUVECs) and apoE knockout mice and whether the combination of rosuvastatin and probucol enhanced this effect. The role that microRNA (miR)-497 plays in the regulation of MMP-9 expression was evaluated in cultured HUVECs and apoE knockout mice using quantitative real-time reverse transcription polymerase chain reaction and Western blotting. First, TNFα significantly increased mitogen-activated protein kinases/extracellular signal-regulated kinase (MAPK/ERK) signaling and MMP-9 levels, and the transfection of miR-497 prevented this increase. The converse results were obtained after miR-497 suppression. Second, the administration of rosuvastatin or the combination of two drugs decreased MAPK/ERK signaling and MMP-9 levels, and the suppression of miR-497 upregulated these levels. Third, the administration of rosuvastatin or the combination of two drugs increased miR-497 expression levels in the aortas of apoE knockout mice, but the levels of serum lipids and plaque areas decreased, which improved plaque components and decreased the MAPK/ERK signaling and MMP-9 levels. Finally, the combination of the two drugs was more effective than the use of rosuvastatin alone. Rosuvastatin inhibits MMP-9 expression by upregulating miR-497 in HUVECs and apoE knockout mice, and the combination of rosuvastatin and probucol enhances this effect.

    ABSTRACT: Over the past several years, non-vitamin K oral anticoagulants (NOACs) have been introduced into clinical practice for the treatment of venous thromboembolism and prevention of stroke in patients with nonvalvular atrial fibrillation. Clinical trials have shown these agents to have similar or less risk of major bleeding as compared to warfarin therapy. Moreover, when patients do experience a major bleeding event administration of advanced factor products is rare, and post-bleed outcomes are similar in those receiving a NOAC compared to those receiving warfarin. However, there are situations where urgent reversal of NOAC anticoagulation would be desirable. The following review focuses on the outcomes and management strategies for patients experiencing a major bleed with warfarin or NOAC agents and describes the rationale for the development of therapies capable of targeted NOAC-reversal.

    ABSTRACT: Thrombelastographic methods have been recently introduced to detect iron mediated hypercoagulability in settings such as sickle cell disease, hemodialysis, mechanical circulatory support, and neuroinflammation. However, these inflammatory situations may have heme oxygenase-derived, coexistent carbon monoxide present, which also enhances coagulation as assessed by the same thrombelastographic variables that are affected by iron. This brief report presents a novel, Sonoclot-based method to detect iron enhanced coagulation that is independent of carbon monoxide influence. Future investigation will be required to assess the sensitivity of this new method to detect iron mediated hypercoagulability in clinical settings compared to results obtained with thrombelastographic techniques.

    ABSTRACT: Anticoagulant thromboprophylaxis with low molecular weight heparin is widely used in nonsurgical settings. To obtain best estimates of the effects of nadroparin for the prevention of venous thromboembolism (VTE) in nonsurgical patients, we conducted a systematic review and meta-analysis. Data sources were Medline, Embase, and Cochrane Library supplemented with conference abstracts, without language restrictions. Selection criteria were randomized controlled trials with nadroparin at prophylactic dose in adult nonsurgical patients. Main efficacy outcomes were major VTE (the composite of symptomatic deep vein thrombosis, symptomatic pulmonary embolism, asymptomatic proximal deep vein thrombosis and VTE-related death) and symptomatic VTE. The main safety outcome was major bleeding. We expressed treatment effects as risk ratios. Ten studies (4 vs. placebo or no treatment, 4 vs. UFH, 1 vs. fondaparinux and 1 vs. warfarin) enrolling a total of 7658 patients were included. In comparison with placebo, nadroparin reduced major VTE by about one-half (RR 0.48, 95% CI 0.24-0.97) with a consistent effect on symptomatic VTE (RR 0.69, 95% CI 0.46-1.05) and no increase in major bleeding (RR 1.51, 95% CI 0.40-5.79). In comparison with other pharmacological prophylaxis, nadroparin was similarly efficacious for prevention of major VTE (RR 1.14, 95% CI 0.63-2.10) and symptomatic VTE (RR 1.10, 95% CI 0.51-2.35) and produced similar effects on major bleeding (RR 0.60, 95% CI 0.25-1.50). Five studies were open label, and for three of these the adjudication method was not described or not blinded. In nonsurgical populations at risk of VTE, nadroparin reduced VTE by about one half compared with placebo or no treatment and appeared similarly effective and safe as other prophylactic anticoagulants.

    ABSTRACT: We performed a meta-analysis to evaluate gender differences of venous thromboembolism (VTE) risk after total hip (THA) and total knee arthroplasty (TKA). We searched PubMed and Web of Knowledge from their beginning to 25 July 2015. Pooled odds ratio (OR) and 95 % confidence interval (CI) for VTE risk were calculated. Twenty studies with 7,892,585 patients were included in our study. The VTE incidence ranged from 0.27 to 61.0 %. The sex ratio (male/female) was 0.623 (3,016,648/4,839,785) in no VTE group versus 0.492 (11,926/24,226) in VTE group. The pooled OR was 1.184 (95 % CI 1.070-1.310; Z = 3.28, P = 0.001). The Begg's test (z = 1.46, P = 0.144) and the Egger's test (t = 0.58, P = 0.571), and the funnel plot suggested there was no significant publication bias. Sensitivity analysis by omitted a study with largest simple size showed the pooled OR was 1.166 (95 % CI 1.051-1.294; Z = 2.91, P = 0.004) by random-effects model. Meta-regression showed VTE risk was not related with THA and TKA incidence (t = 0.35, P = 0.732). Our meta-analysis showed female patients have slightly higher risk of VTE than male patients after THA and TKA.
