Background: The most commonly used oral anticoagulant is acenocoumarol with the brand name is Sintrom and recently, warfarin with the brand name is Coumadin has begun to be used. Anticoagulation with vitamin K antagonists faces two main obstacles: the narrow therapeutic range and the effectiveness of the drug varies by many factors. Objective: " Current status of coagulation disorders in the treatment of anticoagulants with vitamin K antagonists. Understanding some factors affecting the goal of anticoagulant treatment". Method: Cross-sectional, retrospective, descriptive analysis of drug use and influencing factors of patients diagnosed with coagulopathy admitted to the emergency department at Hanoi Heart Hospital from April 2020 to August 2021. Results: There were 675 patients admitted to the hospital with blood clotting disorders. The average age is 60,17±10,13, the youngest is 30, the oldest is 90; 63 patients, accounting for 9.42%, need to be hospitalized for inpatient treatment; There are 108 patients, accounting for 16%, with bleeding and 18 patients, accounting for 2.7%, with thromboembolism or valve obstruction. Conclusion: Coagulation disorders during treatment with vitamin K antagonist anticoagulants is a common condition in the emergency department. However, the complication rate is not high. There are many factors that affect the patient's treatment goals and the drug use is a fairly common factor.

Pharmacological Cardioversion

The therapeutic dilemma between rhythm and rate control in the management of atrial fibrillation (AF) is still unresolved and electrical or pharmacological cardioversion (CV) frequently represents a useful strategy. The most recent guidelines recommend anticoagulation according to individual thromboembolic risk. Vitamin K antagonists (VKAs) have been routinely used to prevent thromboembolic events. Non-vitamin K antagonist oral anticoagulants (NOACs) represent a significant advance due to their more predictable therapeutic effect and more favorable hemorrhagic risk profile. In hemodynamically unstable patients, an emergency electrical cardioversion (ECV) must be performed. In this situation, intravenous heparin or low molecular weight heparin (LMWH) should be administered before CV. In patients with AF occurring within less than 48 h, synchronized direct ECV should be the elective procedure, as it restores sinus rhythm quicker and more successfully than pharmacological cardioversion (PCV) and is associated with shorter length of hospitalization. Patients with acute onset AF were traditionally considered at lower risk of thromboembolic events due to the shorter time for atrial thrombus formation. In patients with hemodynamic stability and AF for more than 48 h, an ECV should be planned after at least 3 weeks of anticoagulation therapy. Alternatively, transesophageal echocardiography (TEE) to rule out left atrial appendage thrombus (LAAT) should be performed, followed by ECV and anticoagulation for at least 4 weeks. Theoretically, the standardized use of TEE before CV allows a better stratification of thromboembolic risk, although data available to date are not univocal.

Deep Vein

Inferior vena cava (IVC) agenesis is a rare congenital abnormality affecting the infrarenal segment, the suprarenal or the whole of the IVC. It has an estimated prevalence of up to 1% in the general population that can rise to 8.7% when abnormalities of the left renal vein are considered. Most IVC malformations are asymptomatic but may be associated with nonspecific symptoms or present as deep vein thrombosis (DVT). Up to 5% of young individuals under 30 years of age with unprovoked DVT are found to have this condition. Regarding the treatment of IVC agenesis-associated DVT, there are no standard guidelines. Treatment is directed towards preventing thrombosis or its recurrence. Low molecular weight heparin and oral anticoagulation medication, in particular vitamin K antagonists (VKAs) are the mainstay of therapy. Given the high risk of DVT recurrence in these patients, oral anticoagulation therapy is suggested to be pursued indefinitely. As far as we know, this is the first case reporting the use of a direct factor Xa inhibitor in IVC agenesis-associated DVT. Given VKA monitoring limitations, the use of a direct Xa inhibitor could be an alternative in young individuals with anatomical defects without thrombophilia, but further studies will be needed to confirm its efficacy and safety.

Background and objectives: Anticoagulants are thought to increase the risks of traumatic intracranial injury and poor clinical outcomes after blunt head trauma. The safety of using direct oral anticoagulants (DOACs) compared to vitamin K antagonists (VKAs) after intracranial hemorrhage (ICH) is unclear. This study aims to compare the incidence of post-traumatic ICH following mild head injury (MHI) and to assess the need for surgery, mortality rates, emergency department (ED) revisit rates, and the volume of ICH. Materials and Methods: This is a retrospective, single-center observational study on all patients admitted to our emergency department for mild head trauma from 1 January 2016, to 31 December 2018. We enrolled 234 anticoagulated patients, of which 156 were on VKAs and 78 on DOACs. Patients underwent computed tomography (CT) scans on arrival (T0) and after 24 h (T24). The control group consisted of patients not taking anticoagulants, had no clotting disorders, and who reported an MHI in the same period. About 54% in the control group had CTs performed. Results: The anticoagulated groups were comparable in baseline parameters. Patients on VKA developed ICH more frequently than patients on DOACs and the control group at 17%, 5.13%, and 7.5%, respectively. No significant difference between the two groups was noted in terms of surgery, intrahospital mortality rates, ED revisit rates, and the volume of ICH. Conclusions: Patients with mild head trauma on DOAC therapy had a similar prevalence of ICH to that of the control group. Meanwhile, patients on VKA therapy had about twice the ICH prevalence than that on the control group or patients on DOAC, which remained after correcting for age. No significant difference in the need for surgery was determined; however, this result must take into account the very small number of patients needing surgery.

AbstractThe number of patients with atrial fibrillation (AF) is increasing due to the aging of the population. In addition, the number of patients with AF and an indication for oral anticoagulation (OAC) for the prevention of strokes increases, who are in need for a dual antiplatelet therapy (DAPT) with acetyl salicylic acid (ASA) plus a P2Y12-Inhibitor because of an acute coronary syndrome and/or coronary stent implantation. These patients did receive a triple therapy (TT) for 3–12 months in the past. Triple therapy never has been studied for efficacy or safety, however, the rate of bleeding complications in comparison to OAC or DAPT is significantly higher.Registries and smaller trials showed that dual therapy with an OAC plus a single platelet inhibitor may be sufficient to prevent strokes and stent thromboses/myocardial infarctions. Four prospective randomized trials involving all four NOACs (Non-Vitamin K oral anticoagulants) approved for stroke prevention in AF have been undertaken. The NOACs plus one antiplatelet agent were tested versus vitamin K-antagonists plus DAPT. In the meantime, the trials involving rivaroxaban (PIONEER AF-PCI), dabigatran (RE-DUAL PCI), apixaban (AUGUSTUS), and edoxaban (ENTRUST-AF-PCI) have been published. The current status is that a NOAC plus a single antiplatelet agent, mostly clopidogrel, is superior to TT with respect to the bleeding complications, without any obvious and statistically significant disadvantage for stroke rates or cardiac ischemic events. The international guidelines already recommend to treat with a NOAC and one antiplatelet agent instead of TT in case the patients bleeding risk is prevailing. Thus, TT seems not to be indicated anymore for most patients with AF and ACS or PCI.

Background There is a lower reported incidence of intracranial hemorrhage with non-vitamin K antagonist oral anticoagulants compared with vitamin K antagonist. However, the functional outcome and mortality of intracranial hemorrhage patients were not assessed. Aims To compare the outcome of vitamin K antagonists- and non-vitamin K antagonist oral anticoagulants-related intracranial hemorrhage. Methods We included consecutive patients with acute non-traumatic intracranial hemorrhage on oral anticoagulation therapy admitted between January 2013 and June 2015 at four university hospitals. Clinical and demographic data were obtained from individual medical records. Intracranial hemorrhage was classified as intracerebral, extra-axial, or multifocal using brain computed tomography. Three-month functional outcome was assessed using the modified Rankin Scale. Results Among 246 patients included, 24 (9.8%) were anticoagulated with a non-vitamin K antagonist oral anticoagulants and 222 (90.2%) with a vitamin K antagonists. Non-vitamin K antagonist oral anticoagulants patients were older (81.5 vs. 76 years, p = 0.048) and had intracerebral hemorrhage more often (83.3% vs. 63.1%, p = 0.048). We detected a non-significant trend for larger intracerebral hemorrhage volumes in vitamin K antagonists patients ( p = 0.368). Survival analysis adjusted for age, CHA2DS2VASc, HAS-BLED, and anticoagulation reversal revealed that non-vitamin K antagonist oral anticoagulants did not influence three-month mortality (hazard ratio (HR) = 0.83, 95% confidence interval (CI) = 0.39–1.80, p = 0.638). Multivariable ordinal regression for three-month functional outcome did not show a significant shift of modified Rankin Scale scores in non-vitamin K antagonist oral anticoagulants patients (odds ratio (OR) 1.26, 95%CI 0.55–2.87, p = 0.585). Conclusions We detected no significant differences in the three-month outcome between non-vitamin K antagonist oral anticoagulants- and vitamin K antagonists-associated intracranial hemorrhage, despite unavailability of non-vitamin K antagonist oral anticoagulants-specific reversal agents.

Bleeding Risk

Atrial fibrillation (AF) is a strong risk factor for ischemic stroke and systemic embolism. To prevent thromboembolic events in patients with AF, anticoagulation therapy is essential. The anticoagulant strategy is determined after stroke and bleeding risk assessments using the CHA2DS2-VASc and HAS-BLED scores, respectively; both consider clinical risk factors. Vitamin K antagonists (VKAs) are the sole anticoagulant option in AF patients with a prosthetic mechanical valve or moderate-severe mitral stenosis; in all other AF patients VKA or non-vitamin K antagonist oral anticoagulants are therapeutic options. However, antiplatelet therapy should not be used for stroke prevention in AF patients. Anticoagulation is not needed in AF patients with low stroke risk but strongly recommended in those with a with low bleeding risk. Left atrial appendage (LAA) occlusion offers an alternative in AF patients in whom long-term anticoagulation is contraindicated. Surgical occlusion or the exclusion of LAA can be considered for stroke prevention in AF patients undergoing cardiac surgery. In this article, we review existing data for stroke prevention and suggest optimal strategies to prevent stroke in AF patients.

: Anticoagulation therapy is the cornerstone of treatment in acute vein thrombosis (DVT) and it aims to reduce symptoms, thrombus extension, DVT recurrences, and mortality. The treatment for DVT depends on its anatomical extent, among other factors. Anticoagulation therapy for proximal DVT is clearly recommended (at least for 3 months), while AT for isolated distal DVT should be considered, especially in the presence of high thromboembolic risk factors. The optimal anticoagulant and duration of therapy are determined by the clinical assessment, taking into account the thromboembolic and bleeding risk in each patient in a case-by-case decision making. Non-Vitamin K antagonists oral anticoagulants (NOACs) were a revolution in the anticoagulation management of DVT. Nowadays, NOACs are considered as first-line therapy in the anticoagulation therapy for DVT and are recommended as the preferred anticoagulant agents by most scientific societies. NOACs offer a simple route of administration (oral agents), a rapid onset-offset of their action along with a good efficacy and safety profile in comparison with Vitamin K Antagonists (VKAs). However, there are issues about their efficacy and safety profile in specific populations with high thromboembolic and bleeding risks, such as renal failure patients, active-cancer patients, and pregnant women, in which VKAs and heparins were the standard care of treatment. Since the available data are promising for the use of NOACs in end-stage chronic kidney disease and cancer patients, several ongoing randomized trials are currently trying to solve that issues and give evidence about the safety and efficacy of NOACs in these populations.
