Our study aims to compare the utility of single antiplatelet therapy (SAPT) with dual antiplatelet therapy (DAPT) following Left atrial appendage occlusion in patients whose post-procedural oral anticoagulation therapy was deemed high-risk or contraindicated. A total of 14 observational studies with 3,151 patients were included. Our study demonstrates that SAPT and DAPT were similar in preventing device-related thrombosis. Although SAPT and DAPT had a tendency toward a higher risk for stroke and major bleeding respectively, these differences did not reach statistical significance. Large-scale Randomized Controlled Studies are warranted to validate if our results could be translated into clinical practice.

Aspirin versus Clopidogrel monotherapy beyond 1 month after complex percutaneous coronary intervention: A pre-specified subgroup analysis of the STOPDAPT-3 trial.

Aims: There were no previous studies comparing aspirin versus P2Y12 inhibitor monotherapy following short dual antiplatelet therapy (DAPT) after complex percutaneous coronary intervention (PCI).
Methods And Results: We conducted a prespecified subgroup analysis based on complex PCI in the 1-year results of the STOPDAPT-3 trial, which randomly compared 1-month DAPT followed by aspirin monotherapy (aspirin group) to 1-month prasugrel monotherapy followed by clopidogrel monotherapy (clopidogrel group). The main analysis in the present study was the 30-day landmark analysis.
Ischemic stroke can cause damage to neurons, resulting in neurological dysfunction. The main treatments in the acute phase include intravenous thrombolysis, endovascular stent-assisted vascular thrombectomy and antiplatelet therapy. Due to the limitations of the time window and the risk of early intracranial hemorrhage, finding active treatment plans is crucial for improving therapy.

Introduction: Aspirin is commonly recommended for individuals who have experienced stroke or myocardial infarction (MI). Indobufen, a cyclooxygenase-1 inhibitor, has been studied as a potential alternative. We conducted a meta-analysis and trial sequential analysis (TSA) to compare indobufen with aspirin in patients requiring antiplatelet therapy.

Platelet aggregation and inflammation play a crucial role in atherothrombosis. Wine contains micro-constituents of proper quality and quantity that exert cardioprotective actions, partly through inhibiting platelet-activating factor (PAF), a potent inflammatory and thrombotic lipid mediator. However, wine cannot be consumed extensively due to the presence of ethanol.

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.
