The combination of AF and coronary artery disease not only is a common clinical setting, it is also a complex setting to deal with anticoagulation and antiplatelet therapy, and it is associated with significantly higher mortality rates. Unfortunately, there are no sufficient data available to optimally guide clinical practice in such settings. This review focuses specifically on newer oral anticoagulants (NOACs) associated with dual antiplatelet therapy (DAPT) in patients with coronary artery disease undergoing percutaneous coronary intervention (PCI)...

In the past decade Direct Oral Anti-Coagulants (DOACs), targeting Thrombin or Factor Xa, have enormously facilitated the daily treatment of all relevant patients, including those requiring lifelong therapy. These DOACs have considerable advantages over the use of oral Vitamin K Antagonist (VKA) treatments, in view of having little interferences with food and other medications and also not requiring adjustment for age, gender or weight, with some well-defined exceptions. In this current What's Happening Section we focus on measurements of DiXaIs in plasma using anti-Xa assays, with the objective of providing a tribute to Professor Michel Meyer Samama, who was not only a real leader in this field but, in the past, both authors benefited from his wisdom, as a teacher who dedicated his scientific and professional life (among many other interests in hemostasis, thrombosis and fibrinolysis) to develop and promote methods and strategies for laboratory monitoring of anticoagulants...

Anticoagulants such as heparins and vitamin K antagonists (VKA) are effective for thrombosis prevention and treatment, but are associated with the risk of bleeding and other limitations, spurring the search for improved drugs. Areas covered: to evaluate the newer anticoagulants, focusing on those tested in phase III clinical trials such as direct oral anticoagulants (DOACs), antisense oligonucleotides (ASO) and warfarin analogues. DOACs such as dabigatran, rivaroxaban, apixaban and edoxaban are licensed for stroke prevention in atrial fibrillation and treatment of venous thromboembolism, dabigatran, rivaroxaban and apixaban for postoperative thromboprophylaxis in patients undergoing elective hip or knee arthroplasty and rivaroxaban for secondary prevention of acute coronary syndromes...

BACKGROUND: Since the introduction of newer, more potent P2Y12 receptor inhibitors (P2Y12ris), practice patterns and associated clinical outcomes in patients with myocardial infarction (MI) undergoing percutaneous coronary intervention (PCI) and also requiring oral anticoagulation (OAC) have not been fully characterized. METHODS: The Canadian Observational Antiplatelet Study was a prospective, multicenter, longitudinal, observational study (26 hospitals, December 2011 to May 2013) describing P2Y12ri treatment patterns and outcomes in patients with ST-elevation and non-ST-elevation MI undergoing PCI...

Antithrombotic drug therapy is a main cornerstone - sometimes a fairly uneven cornerstone - of today's clinical practice. Patients treated with antithrombotic drugs appear sometimes unawaited at those of our colleagues, who are not necessarily experts of this narrow field. Furthermore, new and newer molecules of antiplatelet and anticoagulant medicines have come into practice, frequently in combination. This dramatic development has been important to patients; pharmacological - and recently nonpharmacological - antithrombotic treatment has paved the way to improve current modalities in cardiology...

Spontaneous intracerebral hemorrhage (ICH), defined as nontraumatic bleeding into the brain parenchyma, is the second most common subtype of stroke, with 5.3 million cases and over 3 million deaths reported worldwide in 2010. Case fatality is extremely high (reaching approximately 60 % at 1 year post event). Only 20 % of patients who survive are independent within 6 months. Factors such as chronic hypertension, cerebral amyloid angiopathy, and anticoagulation are commonly associated with ICH. Chronic arterial hypertension represents the major risk factor for bleeding...

The new direct oral anticoagulants-dabigatran etexilate, rivaroxaban, and apixaban- have predictable pharmacokinetic and pharmacodynamic profiles and are alternatives to warfarin. However, many surgeons are wary of these drugs, as there is limited evidence on how to manage bleeding in patients taking them, and only recently has a specific antidote been developed to reverse their anticoagulant effect. Management of the newer agents requires careful adherence to primary measures of bleeding care, knowledge of their mechanism of action, and familiarity with the unapproved and untested reversal strategies that may be required in patients with life-threatening bleeding...

Atrial fibrillation (AF) is the most common arrhythmia treated in the clinical practice. One of the major complications of AF is a thromboembolic cerebral ischemic event. Up to 20% of all strokes are caused by AF. Thromboembolic cerebral ischemic event in patients with AF occurs due to atrial thrombi, mainly from the left atrial appendage (LAA). Prevention of clot formation with antiplatelet agents and especially oral anticoagulants (vitamin K antagonists or newer oral anticoagulants) has been shown to be effective in reducing the stroke risk in patients with AF but has several drawbacks with (major) bleedings as the most important disadvantage...

The thromboembolic risk of atrial fibrillation (AF) is significantly mitigated by oral anticoagulation (OAC) therapy, albeit at an increasing bleeding risk. The general principle is that the expected protective benefit of OAC must not exceed the potential harm conferred by possible bleeding. Over the recent years, the CHA2DS2-VASc score has been proven to be superior to other scores in identifying 'low risk' AF patients. However, even this latest score does not incorporate all possible risk factors causing a high thromboembolic risk, while the individual components of the CHA2DS2-VASc score do not seem to carry equal thromboembolic risk...

Atrial fibrillation (AF) is the most common arrhythmia and its prevalence is increasing due to the progressive aging of the population. About 20% of strokes are attributable to AF and AF patients are at 5-fold increased risk of stroke. The mainstay of treatment of AF is the prevention of thromboembolic complications with oral anticoagulation therapy. Drug treatment for many years has been based on the use of vitamin K antagonists, but recently newer and safer molecules have been introduced (dabigatran etexilate, rivaroxaban, apixaban and edoxaban)...

BACKGROUND: It is a well-known fact that very few patients of stroke arrive at the hospital within the window period of thrombolysis. Even among those who do, not all receive thrombolytic therapy. OBJECTIVE: The objectives of this study were to determine the proportion of early arrival ischemic strokes (within 6 h of stroke onset) in our hospital and to evaluate the causes of nonadministration of intravenous and/or intraarterial thrombolysis in them. MATERIALS AND METHODS: Data of all early arrival acute stroke patients between January 2010 and January 2015 were included...

Cancer patients are at major risk of developing venous thromboembolism (VTE), resulting in increased morbidity and economic burden. While a number of theories try to explain its pathophysiology, its risk stratification can be broadly done in cancer-related, treatment-related, and patient-related factors. Studies report the prophylactic use of thrombolytic agents to be safe and effective in decreasing VTE-related mortality/morbidity especially in postoperative cancer patients. Recent data also suggest the prophylactic use of low molecular weight Heparins (LMWHs) and Warfarin to be effective in reducing VTEs related to long-term central venous catheter use...

Venous thromboembolism (VTE) is a prevalent, potentially fatal health problem. Although standard anticoagulant therapy is effective when compared with the newer direct oral anticoagulants (DOACs), it has disadvantages. Heparin and its derivatives must be administered parenterally, whereas use of oral vitamin K antagonists is complicated by unpredictable pharmacokinetics and pharmacodynamics, drug-food and drug-drug interactions and the requirement for frequent laboratory monitoring. Randomized phase 3 trials have demonstrated that patients receive similarly effective anticoagulation with the DOACs dabigatran, edoxaban, rivaroxaban and apixaban when compared with warfarin, with similar or reduced risk of bleeding...

Warfarin is very effective in preventing stroke in patients with atrial fibrillation. However, its use is limited due to fear of hemorrhagic complications, unpredictable anticoagulant effects related to multiple drug interactions and dietary restrictions, a narrow therapeutic window, frequent difficulty maintaining the anticoagulant effect within a narrow therapeutic window, and the need for inconvenient monitoring. Several newer oral anticoagulants have been approved for primary and secondary prevention of stroke in patients with non-valvular atrial fibrillation...

WHAT IS KNOWN AND OBJECTIVE: Antithrombotics for stroke prevention in atrial fibrillation (AF) are reportedly underutilised. Since the burden of care lies within general practice, attention must be paid to identifying and addressing practice gaps in this setting. The objective of this study was to determine the contemporary utilisation of antithrombotic therapy for stroke prevention in AF within Australian general practice (GP). METHODS: Data pertaining to AF patients' (aged ≥65 years) were collected from GP surgeries in New South Wales, Australia, using purpose-designed data collection forms; extracted data comprised patients' medical histories, current pharmacotherapy, and relevant characteristics...

Chronic anticoagulation is common in patients undergoing total joint arthroplasty (TJA). The newer novel oral anticoagulants dabigatran, rivaroxaban, and apixaban target individual factors in the clotting cascade (factors Xa, IIa). The stable pharmacokinetics of these medications provide improved efficacy and safety with equivalent or superior antithrombotic properties. There are no management guidelines for these newer anticoagulants in TJA. Understanding the pharmacokinetics, conventional laboratory tests, dosing, and reversal methods that can be used for coagulation hemostasis is crucial for surgeons who are deciding whether to operate now or later...

Anticoagulants are the cornerstone of treatment of venous thromboembolism associated with various medical conditions and surgical procedures. They act on different steps of the coagulation pathway and are broadly categorized into heparins, vitamin K antagonists, and inhibitors of thrombin and factor Xa. The classification is evolving as newer and better oral and parenteral anticoagulants are being added. Anticoagulants in dermatology are important not only for their therapeutic application in cutaneous thrombotic dermatoses such as livedoid vasculitis, purpura fulminans, superficial and deep venous thrombosis and others but also for their use in non-thrombotic dermatoses such as lichen planus, recurrent oral aphthosis, chronic urticaria and several others...

Vitamin K antagonists (VKAs) are effective oral anticoagulants that are titrated to a narrow therapeutic international normalized ratio (INR) range. We reviewed published literature assessing the impact of INR stability - getting into and staying in target INR range - on outcomes including thrombotic events, major bleeding, and treatment costs, as well as key factors that impact INR stability. A time in therapeutic range (TTR) of ≥65 % is commonly accepted as the definition of INR stability. In the real-world setting, this is seldom achieved with standard-of-care management, thus increasing the patients' risks of thrombotic or major bleeding events...

Anticoagulation therapy is indicated for management of various clinical conditions to prevent adverse events and introduction of direct oral anticoagulants (DOACs) has ushered in a new era in anticoagulation therapy. Major advantages of DOACS include fewer drug interactions and that they do not need periodic monitoring. Several patients who were not on anticoagulation before due to older age, polypharmacy/drug interaction concerns, and logistics of periodic monitoring are now on anticoagulation with DOACs. Despite their many advantages, a challenge while prescribing DOACs is very limited availability of specific reversal agents and lack of understanding or guidance about the treatment strategy in case of major life threatening bleeding or need for urgent surgery...

PURPOSE OF REVIEW: The optimal antithrombotic therapy in patients with atrial fibrillation undergoing percutaneous coronary intervention (PCI) is still debated. This review is an update of a previous review and aims to summarize new published data regarding the management of this group of atrial fibrillation patients. RECENT FINDINGS: Recent data report an underuse of oral anticoagulation in patients with atrial fibrillation undergoing PCI while indicated. However, tools for risk assessment and thus better guidance for decision-making are lacking, especially for elderly atrial fibrillation patients...
