Background: Managing antiplatelet and anticoagulant drugs before endoscopy may be challenging.
Aims: To assess whether the pre-endoscopic management of antiplatelet/anticoagulant drugs is adherent to current guidelines and the influence of patients' characteristics, referring physician's specialty, type of endoscopic procedure and therapeutic regimen on adherence.
Methods: Two hundred and twenty patients taking aspirin, thienopyridines or warfarin and scheduled for upper endoscopy (± biopsies), variceal band ligation, colonoscopy (± biopsies or polypectomy), were prospectively analyzed.
Results: In 109 patients (49.5%) the management of antiplatelet/anticoagulant drugs was thoroughly compliant with guidelines. Neither demographic characteristics, nor in/outpatient status, nor type of endoscopic procedure, nor physician's specialty influenced the adherence but the therapeutic regimen had a significant impact (p < 0.0001) as compliance was less likely in patients on warfarin. Unwarranted drugs withholding was more frequent before colonoscopy than upper endoscopy (p = 0.0001). Warfarin was stopped longer than recommended more frequently than aspirin (p = 0.009). The International Normalized Ratio was properly checked before endoscopy in 47.7% of patients. Among the 55 patients who withheld warfarin, the decision about bridging to low molecular weight heparin was appropriate in 21 (38.2%).
Conclusions: Compliance with guidelines is low especially in the management of warfarin, both among gastroenterologists and other physicians.

Design and early progress of the Comparison of Anticoagulation and anti-Platelet Therapies for Intracranial Vascular Atherostenosis (CAPTIVA) trial.

Medical University of South Carolina, Charleston, SC, USA.
Background: The usual antithrombotic treatment for symptomatic intracranial atherosclerotic stenosis (ICAS) consists of dual treatment with clopidogrel and aspirin for 90 days followed by aspirin alone but the risk of recurrent stroke remains high up to 12 months. The Comparison of Anticoagulation and anti-Platelet Therapies for Intracranial Vascular Atherostenosis (CAPTIVA) trial was designed to determine whether other combinations of dual antithrombotic therapy are superior to clopidogrel and aspirin.
Methods: CAPTIVA is an ongoing, prospective, double-blinded, three-arm clinical trial at over 100 sites in the United States and Canada that will randomize 1683 high-risk subjects with a symptomatic infarct attributed to 70-99% stenosis of a major intracranial artery to 12 months of treatment with (1) ticagrelor (180 mg loading dose, then 90 mg twice daily), (2) low-dose rivaroxaban (2.
The efficacy and safety of indobufen in patients with ischemic cardiovascular or cerebrovascular diseases: systematic review and meta-analysis.

Department of Cardiology, Hangzhou Hospital of Traditional Chinese Medicine Affiliated to Zhejiang Chinese Medical University, Hangzhou, Zhejiang, China.
Objective: This meta-analysis aims to evaluate the safety and efficacy of indobufen in the treatment of cardiovascular diseases, cerebrovascular diseases, and thromboembolic disorders. The primary focus is on the incidence of major adverse cardiovascular events (MACE), thrombosis, bleeding events, and adverse reactions. The results are intended to provide a reference for the clinical application of indobufen and suggest directions for further large-scale, multi-center, prospective studies.

Purpose: This large-scale retrospective study aimed to examine the long-term effect of antiplatelet and anticoagulant medications intake on dental implant treatment outcome.
Materials And Methods: This study retrospectively examined data from patients who underwent dental implant procedures at several university dental clinics within the BigMouth network between 2011 and 2022. Patients' characteristics including age, gender, ethnicity, race, tobacco use, systemic medical conditions and intake of antiplatelets and anticoagulants were analyzed.
Suprasternal aortic arch echocardioscopy as a potential tool in detection and follow-up of mobile thrombi in patients with ischemic stroke.
Front Neurol

Neurology Department, Navarre University Hospital, Pamplona, Navarra, Spain.
Introduction: Severe or complicated atheromatosis of the aortic arch represents an important and often underdiagnosed embolic source in patients with ischemic stroke. The presence of a floating thrombus has significant clinical relevance, as it is associated with a high risk of early recurrence. The aim of this study was to analyze the potential of echocardiographic examination through the suprasternal window in both the detection of embolic sources and the monitoring of the response to anticoagulant treatment in patients with mobile thrombi.
