Combination of Oral Anticoagulants and Single Antiplatelets versus Triple Therapy in Nonvalvular Atrial Fibrillation and Acute Coronary Syndrome: Stroke Prevention among Asians
Int J Angiol DOI: 10.1055/s-0040-1708477Atrial fibrillation (AF), the most prevalent arrhythmic disease, tends to foster thrombus formation due to hemodynamic disturbances, leading to severe disabling and even fatal thromboembolic diseases. Meanwhile, patients with AF may also present with acute coronary syndrome (ACS) and coronary artery disease (CAD) requiring stenting, which creates a clinical dilemma considering that majority of such patients will likely receive oral anticoagulants (OACs) for stroke prevention and require additional double antiplatelet treatment (DAPT) to reduce recurrent cardiac events and in-stent th...

Landmark Phase 3 VOYAGER PAD Study of XARELTO ® (rivaroxaban) Plus Aspirin Shows Significant Benefit in Patients with Symptomatic Peripheral Artery Disease (PAD) after Lower-Extremity Revascularization
RARITAN, NJ, March 28, 2020 – The Janssen Pharmaceutical Companies of Johnson & Johnson today announced the VOYAGER PAD study met its primary efficacy and principal safety endpoints, demonstrating the XARELTO® (rivaroxaban) vascular dose (2.5 mg twice daily) plus aspirin (100 mg once daily) was superior to aspirin alone in reducing the risk of major adverse limb and cardiovascular (CV) events by 15 percent in patients with symptomatic peripheral artery disease (PAD) after lower-extremity revascularization, with similar rates of TIMI[1] major bleeding. VOYAGER PAD is the only study to show a significant benefit using...

Clinical Outcomes of Antithrombotic Strategies for Patients with Atrial Fibrillation After Percutaneous Coronary Intervention.
This study aims to explore the best antithrombotic strategy for AF patients after PCI based on a network meta-analysis. This study was registered in PROSPERO (CRD42018093928). The PubMed, Cochrane, and EMBASE databases were searched to identify clinical trials concerning antithrombotic therapy for AF patients with PCI from inception to April 2018. Pairwise and network meta-analysis were conducted to compare clinical outcomes of different antithrombotic therapy. The primary endpoint was major bleeding. Fifteen studies including 16,382 patients were identified with follow-up ranging from 3 to 12 months. Non-vitamin K oral an...

Preventable Cases of Oral Anticoagulant-Induced Bleeding: Data From the Spontaneous Reporting System
Conclusion: Our findings describe the most reported risk factors for preventability of oral anticoagulant-induced bleedings. These factors may be useful for targeting interventions to improve pharmacovigilance activities in our regional territory and to reduce the burden of medication errors and inappropriate prescription. Introduction Oral anticoagulant therapy is widely used for the prevention of stroke and systemic embolism in patients with atrial fibrillation, or for the prevention and treatment of deep vein thrombosis and pulmonary embolism (Raj et al., 1994; Monaco et al., 2017). Oral anticoagulants can be di...

Safety and Efficacy of Triple Antithrombotic Therapy with Dabigatran versus Vitamin K Antagonist in Atrial Fibrillation Patients: A Pilot Study.
Conclusion: Dabigatran at the dose used for stroke prevention appears safer than VKA and maintains a similar efficacy profile, when used with DAPT, in AF patients who have undergone PCI with stenting for ACS. PMID: 30895193 [PubMed - in process]

Benefits and Risks of Anticoagulation in Acute Coronary Syndrome
Conclusions: Many risk factors for ischemic events and bleeding overlap. The clinician's challenges include monitoring patients' adherence and global assessment of the antithrombotic effect that incorporates antiplatelet and anticoagulant effects.

Platelet Surface CD62p and Serum Vitamin D Levels are Associated with Clopidogrel Resistance in Chinese Patients with Ischemic Stroke
Background: To explore the association of platelet activation markers, vitamin D, and antiplatelet drugs resistance in ischemic stroke patients. Methods: A total of 230 patients with ischemic stroke were enrolled in this study. Platelet aggregation, platelet activation marker (CD62p), and vitamin D were measured after 7-14 days of dual antiplatelet treatment (aspirin  + clopidogrel). All individuals were divided into a drug resistance group and a drug sensitive group according to the platelet maximum aggregation rate induced by antagonist adenosine diphosphate or arachidonic acid.

Treatment Failure in Patients Receiving Direct Oral Anticoagulants: Clinical Management and Outcomes from a Single-Center Review of 59 Consecutive Patients
In this study, we sought to characterise DOAC treatment failures in our institution, and to rationalise the subsequent anticoagulation strategies in this setting. All VTE patients starting a DOAC at our centre are followed in a consultant-led clinic. Cases of suspected treatment failure are also referred from other specialities and primary care. Between September 2014 and May 2018, we identified 59 consecutive patients (male/female: 34/25) in whom a DOAC treatment failure was diagnosed, including non-resolution of the presenting complaint, and recurrence of or a new thrombotic event. Patient mean age at DOAC initiation was...

A Study of Haemostatic Parameters in Patients with Philadelphia-Negative Myeloproliferative Neoplasms. Correlation with, Clinical, Laboratory, Molecular, and Treatment Characteristics
DiscussionGlobal assays such as thromboelastography are more useful than conventional hemostatic laboratory tests in depicting the hypercoagulable state in MPN. They may be useful in combination with other parameters such as the mutational status in identifying patients with MPN at higher risk for thrombosis and guide clinicians for the type of treatment (both cytoreductive and anticoagulants). Tests of platelet function assessment may help the clinicians adjust the type and dose of antiplatelet therapy.DisclosuresNo relevant conflicts of interest to declare.

Anticoagulation in Atherosclerotic Disease.
Abstract The prevention of atherothrombotic events is an essential therapeutic goal in the treatment of patients with arteriosclerotic diseases. After plaque rupture, a rapidly growing thrombus can lead to acute vascular occlusion and thus heart attack, stroke or limb ischaemia. The acute therapy combines anticoagulation and platelet inhibition. However, the only available therapy so far in the primary and secondary prevention of stable patients is the platelet inhibitors aspirin and clopidogrel. Despite the use of antiplatelet therapies, including aspirin and P2Y12-receptor antagonists, some patients with artery ...

Pharmacodynamic safety of clopidogrel monotherapy in patients under oral anticoagulation with a vitamin K antagonist undergoing coronary stent implantation.
This study enrolled 100 patients on aspirin plus clopidogrel (DAPT-cohort, without indication for VKA) and 100 patients on clopidogrel monotherapy plus phenprocoumon (OAC-cohort) undergoing elective PCI. Platelet reactivity was assessed by impedance aggregometry on day 1 following PCI. Ischemic (death, stroke, or myocardial infarction) and bleeding (BARC 2-5) events within 12 months were compared in a propensity score adjusted model. Platelet reactivity was not different in the OAC- and DAPT-cohort (187 [127-242] vs. 167 [126-218] AU×min; p = 0.23). Overall, 17 ischemic and 34 bleeding events were recorded during follo...
