Thrombosis is one of the major causes of morbidity and mortality in a wide range of vessels diseases. Due to the high prevalence of thromboembolic disorders investigations are being carried out on new antithrombotic agents with limited adverse side effects in which herbal medicines are considered as alternative remedies. Persian medicine (PM) as a traditional medicine has a good potential for pharmacotherapy based on its own principles and development of drugs via investigating PM literature. In PM manuscripts there are some concepts that express the management of blood clots and antithrombotic properties...

More recent immune thrombocytopenia (ITP) treatment strategies enhance platelet production with the use of thrombopoietin receptor agonists (TPO-RA) such as eltrombopag. Patients receiving TPO-RA agents may be at an increased risk of thromboembolism, however the pathophysiology and common underlying risk factors are not well understood. We present the case of a young asplenic woman on eltrombopag for chronic ITP with acute myocardial infarction involving the right coronary artery. Past medical history was significant for remote mediastinal radiation for lymphoma and splenectomy for ITP...

The objective of this project was to compare the time from initiation of oral anticoagulation to hospital discharge between warfarin and direct oral anticoagulants (DOACs) for the treatment of acute venous thromboembolism (VTE). This retrospective observational study was done at a single VA medical center. A total of 107 patients were included, with 42 patients (39%) in the DOAC group, which included rivaroxaban, dabigatran, and apixaban, and 65 patients (61%) in the warfarin group. Variables collected through chart review included comorbid conditions, time from initiation of oral anticoagulation to discharge, emergency department (ED) visits and readmission within 30 or 90 days, and bleeding events...

According to guidelines, it is recommended to give P2Y12 inhibitors (preferably ticagrelor or prasugrel) at the time of first medical contact in patients with STEMI. However, in real life antiplatelet treatment strategies are different among countries. We analyzed data on antiplatelet treatment in STEMI patients included into Polish ORPKI national registry. A total of 23,139 STEMI patients from 153 invasive cardiology centers were reported in ORPKI registry between September 2015 and August 2016. Finally 19,437 patients from 122 centers (immediate PCI in 94%) were included into the analysis (lack of ticagrelor or prasugrel usage reported in 31 centers)...

Homocysteine and its cyclic ester homocysteine thiolactone (HTL) have been involved in the detrimental consequences associated to hyperhomocysteinemia, an independent risk factor for vascular diseases. HTL reacts with protein lysine residues in a process named N-homocysteinylation. The aim of our study was to evaluate the in vitro effects of HTL on the fibrinogen through electrophoretic methods. Fibrinogen was incubated with HTL at different molar ratios and structural changes of the protein were assessed by polyacrylamide gel electrophoresis (PAGE), capillary zone electrophoresis (CZE) and capillary isoelectric focusing (CIEF)...

The CHA2DS2-VASc score is a validated tool to assess the thromboembolic risk in patients with atrial fibrillation. Pre-stroke CHA2DS2-VASc score may predict outcome in patients with acute ischemic stroke (AIS) without atrial fibrillation. The aim of this study was to investigate if the pre-stroke CHA2DS2-VASc score is able to predict short- and long-term outcomes in AIS patients treated with intravenous thrombolysis (IVT). The study group consisted of 256 consecutive patients admitted to the Udine University Hospital with AIS and underwent IVT between January 2015 to March 2017...

The concept of resistance in blood coagulation has become important. In the past it was limited to the resistance shown by some patients to heparin, coumarin or aspirin. Subsequently, it was demonstrated that a mutation in a single clotting factor, FV, showed resistance to activated protein C. Since activated protein C is supposed to downregulate aFV and aFVIII, their persistence in the circulation gives origin to a hypercoagulable state. Recently antithrombin resistance has been defined. Several prothrombin abnormalities (dysprothrombinemias) have been shown to be resistant to the action of antithrombin...

Cancer is a known hypercoagulable state that leads to an increased risk of venous thromboembolism (VTE). Low molecular weight heparin remains the preferred anticoagulant for VTE in patients with cancer over vitamin K antagonist. However, the preferred anticoagulant in prevention of stroke and systemic embolism in atrial fibrillation (AF) in patients with cancer has yet to be determined. The direct oral anticoagulants (DOACs) are increasingly being utilized; however their role in cancer has only recently been investigated...

The American College of Chest Physicians guidelines recommend unfractionated heparin (UFH), low molecular weight heparins (LMWHs) or fondaparinux for prevention of venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), in medically-ill patients. Direct oral anticoagulants (DOACs) have been evaluated relative to enoxaparin for VTE prophylaxis though head-to-head comparisons of these agents are lacking. Therefore, we conducted a mixed treatment comparisons meta-analysis to evaluate the safety and efficacy of established treatments and DOACs for VTE prophylaxis in medically-ill patients...

Coronary heart disease (CHD) and diabetes mellitus (DM) have high reactivity of platelets and an increased risk of thrombosis. Platelet glycosylation is closely related to platelet function and survival. However, the alteration of platelet glycosylation in CHD and T2DM still remains unknown. Platelet samples were obtained from 55 healthy controls and 102 patients, including 33 CHD, 30 T2DM and 39 CHD complicated with T2DM (CHD + T2DM). Platelet glycosylation was detected using eight-lectin based assay by flow cytometry...

Pregnancy is a well-established risk factor for venous thromboembolism and is associated with a state of hypercoagulability. The use of sensitive and specific biological markers to predict risk factors for thrombosis is essential during pregnancy. Our objective was to investigate the usefulness of thrombin generation test (TGT) as a marker to predict the risk of thrombosis in high risk venous thrombosis (HRVT) pregnancies compared to normal pregnancies. This retrospective study enrolled 134 women with HRVT pregnancies, 78 of whom had monozygotic, spontaneous and untreated pregnancies and formed the study group...

Arterial and venous complications are major causes of morbidity and mortality in myeloproliferative neoplasms (MPNs). MPNs patients, frequently receive heparin. Heparin-induced thrombocytopenia (HIT) is a rare but potentially life-threatening complication resulting in a severe acquired thrombophilic condition. We carried out a retrospective analysis to evaluate occurrence of new thrombotic events during heparin therapy in essential thrombocythemia (ET) patients. We studied 108 ET patients on heparin for treatment of previous thrombotic events or in thromboprophilaxis...

The characteristics of coronary stenosis vary among the different countries or areas. 11,267 patients who have undergone coronary angiography (CAG) from three Southwest China hospitals were investigated. Patient characteristics, coronary stenosis and stent-implant information were recorded and analyzed according to two criteria: "visible stenosis" and "≥ 50% stenosis". The patients who have undergone CAG increased year by year, with patients from 60 to 69 years-old taking the highest ratio (34.69%). Based on the "≥ 50% stenosis" criteria, the stenotic frequency was 40...

Acute myocardial infarction (AMI) is one of the leading causes of morbidity and mortality worldwide, while early diagnosis still represents an upmost priority. While platelet activation is critical for AMI pathogenesis, the role of platelet microRNAs (pmiRNAs) as biomarkers for AMI is unclear. Furthermore, correlations between the levels of pmiRNAs and indices of platelet activity are also unknown. Expression of platelet miR-1, miR-21, miR-126, miR-150 and miR-223 were prospectively assessed in 20 ST-segment elevation myocardial infarction (STEMI) patients, and 40 healthy volunteers...

Antiphospholipid syndrome (APS) is an autoimmune disease that is characterized by arterial and/or venous thrombosis and/or recurrent pregnancy losses. Obstetric APS (OAPS) is considered as a distinct entity from vascular APS (VAPS). In the absence of any additional disease, APS is designated as primary (PAPS), while the term secondary APS (SAPS) is used when other diseases are associated. Catastrophic APS (CAPS) is characterized by the rapid development of multiple thrombosis in various vital organs. The presence of antiphospholipid antibodies (aPL Abs) is considered as a laboratory criterion for APS diagnosis...

Real-world evidence focusing on medication switching patterns amongst direct oral anticoagulant (DOACs) has not been well studied. The objective of this study is to evaluate patterns of prescription switching in non-valvular atrial fibrillation (NVAF) patients initiated on a DOAC and previously naïve to anticoagulation (AC) therapy. Data was obtained from Truven Health MarketScan(®) Commercial and Medicare Supplemental database (2009-2013). AC naïve (those without prior anticoagulant use) NVAF patients initiated on a DOAC, with 6 months of continuous health plan enrollment before and after treatment initiation and maintained on continuous therapy for a minimum of 6 months were included...

In vascular access practices, the internal vessel size is considered important, and a catheter to vessel ratio (CVR) is recommended to assist clinicians in selecting the most appropriate-sized device for the vessel. In 2016, new practice recommendations stated that the CVR can increase from 33 to 45% of the vessels diameter. There has been evidence on larger diameter catheters and increased thrombosis risk in recent literature, while insufficient information established on what relationship to vessel size is appropriate for any intra-vascular device...
