Deep vein thrombosis (DVT) remains a life-threatening complication of arthroplasty. It remains controversial for anticoagulation strategies after total hip arthroplasty (THA). A randomized double-blind study was conducted to determine whether prophylactic anticoagulation was efficient reduce DVT after THA. subjects who underwent uncemented THA were assigned to prophylactic anticoagulation group or non- prophylactic anticoagulation group. Patients were followed up 3 months later after surgery. DVT was tested by contrast venography. Investigator also used logistic regression analysis with variable selection for obtaining the prediction model of DVT. DVT after THA was affected by personal (age) and clinical factors (mechanical compression, duration of surgery). THA with short duration of surgery did not require prophylactic anticoagulation ...
Adherence to oral anticoagulant therapy in secondary stroke prevention – impact of the novel oral anticoagulants Sebastian Luger,1 Carina Hohmann,2 Daniela Niemann,1 Peter Kraft,3 Ignaz Gunreben,3 Tobias Neumann-Haefelin,2 Christoph Kleinschnitz,3 Helmuth Steinmetz,1 Christian Foerch,1 Waltraud Pfeilschifter1 1Department of Neurology, University Hospital Frankfurt, Frankfurt am Main, 2Department of Neurology, Klinikum Fulda gAG, Fulda, 3Department of Neurology, University Hospital Würzburg, Würzburg, Germany Background: Oral anticoagulant therapy (OAT) potently prevents strokes in patients with atrial fibrillation. Vitamin K antagonists (VKA) have been the standard of care for long-term OAT for decades, but non-VKA oral anticoagulants (NOAC) have recently been approved for this indication, and raised many questions, among them their influence on medication adherence. We assessed adherence to VKA and NOAC in secondary stroke prevention. Methods: All patients treated from October 2011 to
The clinical situations include how to initiate and monitor NOAC use, how to measure the anticoagulant effect if needed in specific situations, switching between anticoagulants, ensuring compliance, patients with chronic kidney disease and management of bleeding complications.. NOACs remove the regular monitoring of anticoagulation level that was required for the vitamin K antagonists. But Professor Heidbuchel said: "Compliance is very important for the novel anticoagulant drugs because they have a very short half-life. That means that if you dont take them you will not be protected by anticoagulation and are at greater risk of thromboembolic events.". The document provides tips on how to improve compliance. These include educating patients about the drugs short half-life, and that small minor bleeding such as a nose bleed will stop by itself and patients should continue taking the drug. Compliance can also be improved with a pre-specified follow up scheme.. The guide does not cover the ...
Oral anticoagulant therapy is the mainstay of stroke prevention in patients with atrial fibrillation; it is highly effective at reducing stroke risk, but its use can be limited by increased risk of bleeding. As new oral anticoagulants are available, barriers to optimal use of oral anticoagulation therapy warrant consideration by healthcare professionals and administrators who are seeking to optimize the quality of care for patients with atrial fibrillation.
Denmark MedicalResearch.com: What is the background for this study? What are the main findings?. Response: Atrial fibrillation increases a persons risk of ischemic strokes up to 5-fold. Oral anticoagulation therapy lowers this risk effectively (,60%) and is therefore recommended for patients with atrial fibrillation and at least 1-2 other risk factors for stroke.. Our study show, that oral anticoagulation therapy is still underused in patients with atrial fibrillation - even after a stroke event. In stroke survivors with atrial fibrillation, oral anticoagulation therapy were associated with better outcomes than no oral anticoagulation therapy. MedicalResearch.com: What should readers take away from your report?. Response: Oral anticoagulation therapy is effective (and safe) as secondary stroke prophylaxis in patients with atrial fibrillation.. MedicalResearch.com: What recommendations do you have for future research as a result of this work? Response: Treatment rates with oral anticoagulation ...
https://www.futuremarketinsights.com/reports/sample/REP-GB-10058. Direct Oral Anticoagulants: Market Dynamics. Adoption of direct oral anticoagulants over the exciting alternative to warfarin and is used for the first line choice of treatment for venous thromboembolism and atrial fibrillation which is expected to spur the global direct oral anticoagulants market. Growing approval from the FDA and CE mark for the direct oral anticoagulants will further boost the direct oral anticoagulants market in the near future. Rising cases of thrombosis which is the major cause of morbidity and mortality in various parts of the world is expected to further drive the direct oral anticoagulants market in the forecast period.. However, some factors which might restraint the growth of the direct oral anticoagulants include high cost when compared to warfarin and shorter acting dose which makes it important not to miss any doses. Furthermore, stringent regulations for development of drug is expected to restraint ...
Oral anticoagulants are both one of the most commonly prescribed classes of medication and one associated with the high risk of major complications. This session will focus on the optimal management of this class of medication. It will include discussions of clinically important drug interactions with oral anticoagulants, the role of specialized anticoagulation services, and tips for using vitamin K antagonists.|/p| |p|Dr. Vittorio Pengo will discuss the exclusive use of warfarin treatment in some patient categories despite its decrease after the entry of direct oral anticoagulants (DOACs). The beginning of treatment is of fundamental importance as thrombotic and hemorrhagic complications occur soon after starting treatment as a consequence of poor maintenance of international normalized ratio in the therapeutic range. Dr. Pengo will discuss how to treat an excess or a deficit of anticoagulation after stabilization of treatment, and how to handle bridging therapy in the occasion of surgery or invasive
IMPORTANCE: Deep vein thrombosis (DVT) isolated to the calf veins (distal to the popliteal vein) is frequently detected with duplex ultrasonography and may result in proximal thrombosis or pulmonary embolism (PE).. OBJECTIVE: To evaluate whether therapeutic anticoagulation is associated with a decreased risk for proximal DVT or PE after diagnosis of an isolated calf DVT.. DESIGN, SETTING, AND PARTICIPANTS: All adult patients with ultrasonographic detection of an isolated calf DVT from January 1, 2010, to December 31, 2013, at the Vascular Laboratory of the University of California, Davis, Medical Center were included. Patients already receiving therapeutic anticoagulation and those with a chronic calf DVT, a contraindication to anticoagulation, prior venous thromboembolism within 180 days, or diagnosis of a PE suspected at the time of calf DVT diagnosis were excluded. Data were analyzed from August 18, 2015, to February 14, 2016.. EXPOSURES: Intention to administer therapeutic ...
Oral anticoagulant therapy for patients who are at risk of developing blood clotting problems is used by between 400,000-600,000 Canadians annually. The use of this drug represents the most common cause of patient adverse medical outcomes due to medical errors. Furthermore, many patients have adverse outcomes using these drugs because physicians are not able to predict which patients are likely to have bleeding outcomes. Much effort has gone into developing ways to predict which patients are at risk of clotting but almost no work has gone into ways of predicting which patients would be at high risk of bleeding. This information is required to balance off the risk-benefits and to enable physicians and patients to understand the risks and benefits of taking these medications. Our study will develop a tool that can be used to predict bleeding risk in patients taking oral anticoagulant therapy. It will enable more informed decision making by both physicians and patients and will result in better ...
Antithrombotic medications reduce thromboembolic events by inhibiting platelet aggregation and coagulation. Antiplatelet drugs and oral anticoagulants are examples of antithrombotic medications and are among the most commonly prescribed drugs in both primary and secondary care.1 Clinicians are familiar with their use, however antiplatelets and oral anticoagulants are the drug classes most commonly implicated in adverse drug reactions occurring both in the community and in hospital.23 Increasing numbers of patients have an indication for combination antiplatelet and oral anticoagulant therapy. For example, more than one million people in the UK have atrial fibrillation, of whom approximately one third also have an indication for antiplatelet therapy as secondary prevention.4 Despite the need to understand the balance between benefit and risk, there are limited randomised data investigating antithrombotic co-prescription. Current guidelines are therefore based on expert opinion and the ...
hospitalizations, the excess risk attributable to anticoagulant therapy remained significant after the multivariate adjustment [IRR = 3.94 CI, 95% CI (1.06-14.69), p=0.041]. Finally, there was also a tendency to an increased risk of repeated hospitalizations of ischemic cause in anticoagulated patients [IRR = 5.80, 95% CI (0.86-39.0), p=0.071].. Anticoagulation and recurrent bleeding. There was a tendency of a higher frequency of total hemorrhages and also major hemorrhages in anticoagulated patients [1.93 vs 1.11 (p=0.113) and 1.05 vs 0.32 (p=0.051)]. After multivariate adjustment, we observed a tendency toward an increased risk of recurrent bleeding in the anticoagulated patients [IRR = 4.43, 95% CI (0.94-20.81), p=0.059]. Regarding major bleeding, although the differences were ostensible, these did not become statistically significant [IRR= P13.38, 95% CI (0.47-382.68), p,0.129)].. Time in therapeutic range (TRT) and hemorrhagic events in anticoagulated patients. Our anticoagulated patients ...
The mean Anti-Clot Burden and Benefits and SWAN Score was 93% (56/60) and 83% (24.8/30) respectively reflecting high satisfaction with anti-Xa direct oral anticoagulants. 120 patients stated preference for anti-Xa direct oral anticoagulants over warfarin. Leading perceptions driving this was the reduction in frequency of medical contact and fewer bleeding side effects. Thirteen patients (10.3%) experienced an adverse event after the anti-Xa direct oral anticoagulant switch (majority were non-major bleeding) but most remained on anti-Xa direct oral anticoagulant treatment after management options were implemented with continued high satisfaction scores.. ...
A total of 41 RCTs with 38,645 patients were included in the analysis, among which 2,654 were randomized to HDB tirofiban, 6,752 to abciximab, 1,669 to eptifibatide, 16,500 to heparin, and 11,070 to bivalirudin. Mean age was 64±11 years, 75% were male, 91% were treated with stenting, 71% with clopidogrel, 46% presented with STEMI, and 74% for ACS. As seen in Figure 1, tirofiban was associated with a significant reduction in all-cause mortality compared with eptifibatide or heparin. There was no difference among the GPI therapies for other outcomes including MI, MACE, and major bleeding. However, abciximab was associated with greater risk of thrombocytopenia (p,0.01). Bivalirudin was associated with less major and minor bleeding compared with a GPI anticoagulation strategy. ...
Atrial fibrillation affects millions of patients in the United States and imparts a five-fold increase in stroke risk, as compared to the general population.1 Oral anticoagulation is the mainstay of treatment for thromboprophylaxis in atrial fibrillation patients. Until recently, vitamin K antagonists (warfarin in the US) were the sole option for patients at moderate to high risk for stroke or systemic embolism. Now there are several novel oral anticoagulants (NOAC) available in the US as alternatives to warfarin, with good evidence for their efficacy and safety.2-4 While dabigatran, rivaroxaban, and apixaban have been approved for use, there is little practical and even less published experience with these drugs in common clinical situations that require transitions onto or off of NOACs. We aim to discuss the risk of temporary interruptions, the possible hazard of transitioning from one anticoagulant to another, the pharmacokinetic properties of NOACs, and the data around bridging with oral ...
Title: Pharmacological Strategies for Inhibition of Thrombin Activity. VOLUME: 14 ISSUE: 12. Author(s):S. Alban. Affiliation:Pharmazeutisches Institut,Christian-Albrechts-Universitat zu Kiel, Gutenbergstr. 76, 24118 Kiel,Germany.. Keywords:Glycosaminoglycans, low molecular weight heparins, fondaparinux, pentasaccharides, SR123781A, direct thrombin inhibitors, direct factor Xa inhibitors, dabigatran, rivaroxaban. Abstract: For decades, the options for therapeutic anticoagulation were limited to unfractionated heparin (UFH) and vitamin K antagonists (VKA), and their well-known limitations had to be accepted. With the introduction of the various LMWHs, the short-term anticoagulation could be much improved. The heparins delivered the proof of concept that FXa and thrombin represent suitable targets for therapeutic anticoagulation. Consequently, the search for new anticoagulants focus on inhibitors of thrombin or FXa. Apart from the VKA, the anticoagulants presently available or in an advanced stage ...
Warfarin has been the established oral anticoagulant for the last 50 years, being effective in the prevention and treatment of venous and arterial thromboembolic disorders. However, the frequent requirement for INR monitoring, multiple drug and food interactions have fuelled the need for development of new oral anticoagulants. Dabigatran is the first of a series of new oral anticoagulants that are emerging as the successors to warfarin. This new group of anticoagulants is rapidly gaining FDA and NICE approval and has proven non-inferiority to warfarin and viable alternatives to warfarin in the coming years. Given the obvious impact of this on dental treatment in the primary care and hospital setting this article aims to increase familiarisation with this new medicine group.

Only 53.0% of patients in the study at high risk of stroke were using oral anticoagulants. This proportion increased only slightly in the years 2007-2010. At the same time, higher than expected usage was found in the low-risk groups: 32.1% of people with CHADS2 = 0 and 23.0% with CHA2DS2VASc = 0. While anticoagulation may be appropriate for some of these individuals (for example, those with valvular disease), this suggests that use of these algorithms has still to become established. CHADS2 was first proposed over a decade ago, while CHA2DS2-VASc was introduced much more recently.. The estimated high-risk population increases when more inclusive definitions of hypertension are used. The authors considered the safest to be C, which increases the proportion identified from 56.9% to 65.9%. The additional inclusion of those with raised blood pressure levels (definition D) may be unreliable, particularly given the recent emphasis on home, rather than office-based measurements for diagnosis.23 About ...

The study was stopped early because of clear evidence of superiority of oral anticoagulation therapy. There were 165 primary events in patients on oral anticoagulation therapy (annual risk 3·93%) and 234 in those on clopidogrel plus aspirin (annual risk 5·60%; relative risk 1·44 (1·18-1.76; p=0.0003). Patients on oral anticoagulation therapy who were already receiving this treatment at study entry had a trend towards a greater reduction in vascular events (relative risk 1·50, 95% CI 1·19-1·89) and a significantly (p=0·03 for interaction) lower risk of major bleeding with oral anticoagulation therapy (1.30; 0.94-1.79) than patients not on this treatment at study entry (1·27, 0·85-1·89 and 0·59, 0·32-1·08, respectively ...
Background Real-world studies on anticoagulants are mostly performed on health insurance databases, limited to reported events, and sometimes far from every-day issues in family practice. We assess the presence of data for safe monitoring of oral anticoagulants in general practice, and compare patients knowledge of taking an anticoagulant between vitamin K antagonists (VKA) and direct anticoagulants (DOAC), and the general practitioners perception of their adherence to anticoagulation. Methods The CACAO study is a national cohort study, conducted by general practitioners on ambulatory patients under oral anticoagulant. In the first phase, investigators provided safety data available from medical records at inclusion. They also evaluated patients knowledge about anticoagulation and graded their perception of patients adherence. Results Between April and December 2014, 463 general practitioners included 7154 patients. Renal and hepatic function tests were respectively unavailable in 109 (7.5%) and
This certificate program is a comprehensive program designed to provide pharmacists with the basic knowledge and skills necessary to care for patients taking anticoagulation therapies. By completing this course, pharmacists can earn 22 hours of continuing education credit while becoming certified in anticoagulation management. The Anticoagulation Certificate Program is conducted in two parts: the self-study and live training seminar. To earn a certificate of achievement, participants must successfully complete all components of the program.. PROGRAM OUTCOME: With expanded use of anticoagulant agents, the number of patients receiving these drugs has increased dramatically. Safe and effective anticoagulation must include a number of key components to avoid complications. These include careful patient assessment, an understanding of the clotting cascade and mechanisms of action of anticoagulant therapies, a detailed focus on factors which influence therapy and knowledge of current guidelines. This ...
Intracranial hemorrhage (ICH) is the most feared and devastating complication of oral anticoagulant therapy. When an ICH occurs, the patients situation hinges on the balance between how great is the embolic risk while not receiving anticoagulants, and how big is the threat of the hemorrhage if the anticoagulant effect is not reversed promptly. Although several studies which compared the use of different reversal agents failed to demonstrate any improvement in prognosis and survival, at the present moment the consensus seem to be that anticoagulation should be rapidly reversed after an ICH. The second question to be answered is whether and when should be oral anticoagulation treatment restarted. Although the risk of thromboembolism in patients off anticoagulation seems to be higher than the risk of ICH recurrence, there is a marked paucity of prospective large studies on the real risk of ICH recurrence when OAC is resumed, paucity that probably emphasizes the ethical challenge of prescribing ...

Non-vitamin K antagonist oral anticoagulants (NOACs) include dabigatran, which inhibits thrombin, and apixaban, betrixaban, edoxaban and rivaroxaban, which inhibit factor Xa. In large clinical trials comparing the NOACs with the vitamin K antagonist (VKA) warfarin, dabigatran, apixaban, rivaroxaban and edoxaban were at least as effective for stroke prevention in atrial fibrillation and for treatment of venous thromboembolism, but were associated with less intracranial bleeding. In addition, the NOACs are more convenient to administer than VKAs because they can be given in fixed doses without routine coagulation monitoring. Consequently, the NOACs are now replacing VKAs for these indications, and their use is increasing. Although, as a class, the NOACs have a favourable benefit-risk profile compared with VKAs, choosing among them is complicated because they have not been compared in head-to-head trials. Therefore, selection depends on the results of the individual trials, renal function, the ...
The study indicated that, after accounting for differences in baseline characteristics, there were no apparent differences in outcomes between patients who were and were not prescribed oral anticoagulants. There was also no relationship between the CHA2DS2-VASc score and the probability that patients had filled a prescription for an oral anticoagulant, and ultimately no evidence that the CHA2DS2-VASc risk score can effectively indicate the potential benefits of systemic oral anticoagulants for patients initiating hemodialysis with preexisting Afib.. Additional research is necessary to further guide using anticoagulants in this population.. For more information, read the research poster (which was presented at ASN) here.. ...
Dabigatran and rivaroxaban are 2 novel oral anticoagulant agents that have been shown to be safe and effective for the treatment and prophylaxis of VTE and for the prevention of stroke in atrial fibrillation. Following these results, both drugs were registered for VTE prevention despite the lack of information on the proper method to neutralize their anticoagulant activity. Findings from this study, the first conducted in humans, indicate that a nonactivated PCC immediately reverses the effect of full-dose rivaroxaban in healthy individuals but not dabigatran at the PCC dose used in this study.. Prothrombin complex concentrate (Cofact) was chosen as a method of reversal for both rivaroxaban and dabigatran for the following reasons. It contains 4 coagulation factors, namely factors II (prothrombin), VII, IX, and X, that stimulate thrombin formation, thereby potentially bypassing the anticoagulant effect of both drugs. The assessment of the reversal of the anticoagulant effects was based on ...

Oral anticoagulants (OACs) are indicated for the treatment of thrombosis and in the prevention of thromboembolism.1 This includes the treatment of deep venous thrombosis (DVT) and pulmonary embolism (PE), prevention of thrombosis in medically ill and postsurgical patients, and the prevention of thromboembolic stroke in atrial fibrillation. Patients using OACs are likely to be seen in the emergency department (ED) for the same reasons as other individuals of similar age and health, but also because all anticoagulant therapies carry a risk of treatment-related bleeding that, if it occurs, may require emergent evaluation and treatment.1-4. The vitamin K antagonist (VKA) warfarin (eg, Coumadin, Bristol-Myers Squibb, New York, New York, USA) has been the standard OAC for ,50 years, with ,30 million prescriptions written annually in the USA alone.5 As well as the increased bleeding risk common to anticoagulants, the complex and variable pharmacokinetics and pharmacodynamics of warfarin create the ...

Background: Intravascular clotting and low viscosity of the blood are two extremes of blood pathology that can result in serious consequences threatening the patients life. Medical conditions that trigger blood clotting need to be dealt with so as not to end into the serious complication of this disorder. Replaced heart valve is a treatment that activates the coagulation pathway. Anticoagulation therapy becomes a necessity in these patients. In spite of the beneficial effect of warfarin as a blood anticoagulant drug, high anticoagulation may lead to bleeding and low anticoagulation may lead to thrombosis in these patients. Therefore, the drug must be kept under tight control because it has a narrow therapeutic range. The successful management policy of a patient on anticoagulation therapy is essentially a team work including the combined activities of the medical personnel in charge and the patient him/herself. The patient can be involved through education by implementing a structured ...
Protein S (PS) is a vitamin K-dependent anticoagulant that acts as a cofactor to activated protein C (APC). To date PS has not been shown to possess anticoagulant activity in the absence of APC. In this study, we have developed monoclonal antibody to protein S and used to purify the protein to homogeneity from plasma. Affinity purified protein S (PSM), although identical to the conventionally purified protein as judged by SDS-PAGE, had significant anticoagulant activity in the absence of APC when measured in a factor Xa recalcification time. Using SDS-PAGE we have demonstrated that prothrombin cleavage by factor Xa was inhibited in the presence of PSM. Kinetic analysis of the reaction revealed that PSM competitively inhibited factor Xa mediated cleavage of prothrombin. PS preincubated with the monoclonal antibody, acquired similar anticoagulant properties. These results suggest that the interaction of the monoclonal antibody with PS results in an alteration in the protein exposing sites that mediate the
Importance: Although non-vitamin K antagonist oral anticoagulants (NOACs) are increasingly used to prevent thromboembolic disease, there are limited data on NOAC-related intracerebral hemorrhage (ICH). Objective: To assess the association between preceding oral anticoagulant use (warfarin, NOACs, and no oral anticoagulants [OACs]) and in-hospital mortality among patients with ICH. Design, Setting, and Participants: Retrospective cohort study of 141 311 patients with ICH admitted from October 2013 to December 2016 to 1662 Get With The Guidelines-Stroke hospitals. Exposures: Anticoagulation therapy before ICH, defined as any use of OACs within 7 days prior to hospital arrival. Main Outcomes and Measures: In-hospital mortality. Results: Among 141 311 patients with ICH (mean [SD] age, 68.3 [15.3] years; 48.1% women), 15 036 (10.6%) were taking warfarin and 4918 (3.5%) were taking NOACs preceding ICH, and 39 585 (28.0%) and 5783 (4.1%) were taking concomitant single and dual antiplatelet agents, ...

Novel oral anticoagulants offer equivalent or improved therapeutic profiles compared with warfarin, with less risk of bleeding, no interactions with food, and no need for routine laboratory monitoring. Caution must be exercised in using these drugs in certain patient populations, for example, renal insufficiency, those receiving additional antithrombotic therapy, those with questionable compliance, children, and those with a high risk of gastrointestinal bleeding. One of the novel oral anticoagulants, rivaroxaban, is a direct Factor Xa inhibitor, used to reduce risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation, deep vein thrombosis, and pulmonary embolism ...
The possibility that a hypercoagulable state (thrombotic rebound) may follow anticoagulant therapy1 continues to arouse interest. In a group of patients with various disorders thrombo-embolic complications occurred particularly in the first month after stopping the anticoagulant for three days or more because of bleeding, but were distributed randomly over many months when therapy was withdrawn permanently for other reasons.2 In another study, in patients with non-haemorrhagi strokes due to cerebrovascular disease, the incidence of further non-fatal attacks was significantly increased after gradual withdrawal of anticoagulants over one month,3 although comparison with a control group showed that anticoagulants were quite ineffective in preventing such recurrences.4 5 On the other hand no withdrawal effect was found in two studies of patients with ischaemic heart disease,6 7 or in the incidence of venous thrombosis in a series of injured persons.8. ...
What is the treatment for a pulmonary embolism?. Anticoagulant treatment. Anticoagulation is often called thinning the blood. It alters certain chemicals in the blood to stop clots forming so easily. It doesnt dissolve the clot either. Anticoagulation prevents a PE from getting larger, and prevents any new clots from forming. Anticoagulation treatment is usually started immediately (as soon as a PE is suspected) in order to prevent the clot worsening, while waiting for test results.. Anticoagulation medication comes in two forms: injections and tablets The injectable form is heparin (or similar injections called low molecular weight heparins (LMWH)). A new drug called fondaparinux sodium can be given by injection in some circumstances, either to prevent VTE or treat a PE or DVT. The tablets or syrup are called warfarin. They all belong to the group known as oral anticoagulants.. Anticoagulant treatment is continued until three months after a PE in most cases. Sometimes longer treatment is ...
SUMMARY Antithrombotic drugs are among the most commonly used drugs in medicine and are generally separated into anticoagulants, fibrinolytic agents, and platelet inhibitors based on their primary mechanism of action. For many decades, warfarin, which acts by inhibiting vitamin K action, was the only oral anticoagulant available. Vitamin K antagonists have a prolonged effect, unpredictable pharmacokinetics, and require monitoring, but warfarin was widely used for prevention and treatment. The introduction of novel targeted oral anticoagulants has changed the landscape of anticoagulation. Rivaroxaban, apixaban, and edoxaban are novel oral inhibitors of factor Xa, whereas dabigatran is an orally available inhibitor of thrombin. Unfractionated heparin and the low-molecular-weight heparins are the most commonly used rapidly acting parenteral anticoagulants; they inhibit activated serine proteases through antithrombin. One synthetic agent in this class, fondaparinux, is specific for inhibition of ...

The directly acting oral anticoagulants (DOACs) were introduced on and after 2008. There are five DOACs currently on the market: dabigatran, rivaroxaban, apixaban, edoxaban and betrixaban.[15] They were also previously referred to as "new/novel" and "non-vitamin K antagonist" oral anticoagulants (NOACs). Between 2013/Q2 and 2014/Q4, DOAC use tripled, exhibiting how quickly these new drugs have been adopted by health care providers and patients.[16]. Compared to warfarin, NOACs have a rapid onset action and relatively short half-lives; hence, they carry out their function more rapidly and effectively, and allow for drugs to quickly reduce their anticoagulation effects.[17] Routine monitoring and dose adjustments of NOACs is less important than for warfarin, as they have better predictable anticoagulation activity. In certain circumstances, OCT angiography has the potential for evaluating the effects of intensified antithrombotic therapy.[11]. Both NOACs and warfarin are equivalently effective, ...

To address this controversy in context, each trial involving bivalirudin and primary PCI must be examined in detail. The large (N=3602) HORIZONS Acute Myocardial Infarction (AMI) trial examined a strategy of potent antithrombin alone (bivalirudin) compared with a combination of heparin with mandatory intravenous antiplatelet therapy (glycoprotein inhibition) in a large international trial (N=3602).16 The heparin arm of this trial is strikingly different from the antithrombin arms of PAMI and CADILLAC-heparin was weight-based, infusions were stopped after the PCI, sheaths were removed early, closure devices and radial access were possible, and all patients received dual oral antiplatelet therapy. In this context, bivalirudin provided similar ischemic outcomes to a heparin/GPI strategy and a marked reduction in bleeding complications. On the other hand, acute stent thrombosis rates clearly favored the heparin/GPI strategy: (0.3 versus 1.3%, P,0.001). Given the dichotomy of this trials findings, ...
Results In total, 25 patients were included. The majority were men (sex ratio (M/F)=1.27). Median age was 59 years (range 21-80). 19 cases of deep venous thrombosis, 4 of pulmonary embolisms and 3 of catheter associated thrombosis were diagnosed. As an initial treatment (first 5-10 days) of established VTE, 23 patients were treated with low molecular weight heparin (LMWH). Tinzaparin was prescribed in 22 cases. 2 patients received vitamin K antagonists (VKA). One of these 2 patients did not reach the target international normalised ratio (INR) range. Therefore, LMWH was substituted for VKA. For early maintenance and long term treatment, LMWH was used in 23 patients. The 2 other patients suffered from heparin induced thrombocytopenia during the initial treatment. As a result, LMWH was replaced by VKA. Duration of anticoagulation therapy varied from 2 to 18 months. 6 patients had complications of their VTE during treatment: 3 cases of VTE extension, 2 relapses and 1 case of pulmonary embolism. ...
Venous thromboembolism (VTE) remains a substantial clinical and health-economic burden worldwide and effective anticoagulant treatment is necessary immediately after VTE is suspected to reduce short- and long-term VTE related morbidity and mortality. For decades, low molecular weight heparin (LMWH), fondaparinux and Vitamin K antagonists (VKAs) have been the standard of anticoagulant therapy for VTE patients but these treatment options had clinically relevant drawbacks and limitations. The introduction of non-VKA oral anticoagulants (NOACs) that specifically inhibit either thrombin or factor Xa have resolved many of these drawbacks because these new compounds exhibit a rapid onset and offset of action, fewer food and drug interactions and a predictable anticoagulant effect ...
The most serious and common adverse side effect associated with anticoagulant are increased risk of bleeding, both nonmajor and major bleeding events.[36] Risk of bleeding is dependent on the class of anticoagulant agent used, patients age, and pre-existing health conditions. Warfarin has an estimated Incidence of bleeding of 15-20% per year and life-threatening bleeding rate of 1-3% per year.[37] Newer non-vitamin K antagonist oral anticoagulants appear to have fewer life-threatening bleeding events compared to warfarin.[38][39] Additionally, patients aged 80 years or more may be especially susceptible to bleeding complications, with a rate of 13 bleeds per 100 person-years.[40] Bleeding risk is especially important to consider in patients with renal impairment and NOAC therapy due to the fact that all NOACs, to some extent, are excreted by the kidneys.[41] Thus, patients with renal impairment may be at higher risk of increased bleeding.[42] Nonhemorrhagic adverse events are less common than ...
