Clopidogrel

Summary: The purpose of this investigator-initiated, multicenter, open label, randomized trial is to evaluate 1 month vs. 6 months of dual antiplatelet therapy (DAPT) in patients undergoing lower extremity endovascular revascularization. We hypothesize that extending dual antiplatelet therapy (DAPT) to six months, compared to one month, will improve patency rates of target vessels following peripheral vasc...

Summary: Coronary artery ectasia (CAE) is a condition in which a coronary artery becomes abnormally dilated, measuring at least 50% larger than the adjacent normal segment. Although relatively uncommon, CAE is clinically important because it can lead to abnormal blood flow and increase the risk of blood clot formation. Patients with CAE are at higher risk of angina, myocardial infarction, and complications...

Summary: Results from recent several trials provided data showing limits to the effectiveness of thrombectomy for ischemic stroke due to medium vessel occlusions.The benefit-risk profile of thrombolysis for these patients has never been investigated. We initiated a multicenter, prospective, randomized, open label, blinded-endpoint (PROBE) controlled trial to evaluate the efficacy and safety of tenecteplase...

Summary: The benefit-risk profile of thrombolysis for acute ischemic strokes beyond 24 hours has never been investigated. We initiated a multicenter, prospective, randomized, open label, blinded-endpoint (PROBE) controlled trial to assess the safety and efficacy of tenecteplase (0.25mg/kg, max 25mg) versus standard medical treatment in acute ischemic stroke due to intracranial vessel occlusion between 24-7...

Summary: Currently, aspirin plus clopidogrel is considered as a standard acute treatment of ischemic stroke, based on results of CHANCE and POINT trial. However, still a considerable portion of patients showed early stroke recurrence, especially in those with stroke due to large artery atherosclerosis. Cilostazol may have benefit in reducing early stroke recurrence of neurologic deterioriation. The post-ho...

Summary: To assess whether PFO closure plus antiplatelet therapy is superior to antiplatelet therapy alone and whether oral anticoagulant therapy is superior to antiplatelet therapy to prevent stroke recurrence in patients aged 60 to 80 years with a PFO with large shunt (\> 20 microbubbles) or a PFO associated with an ASA (\> 10 mm), and an otherwise unexplained ischemic stroke.

Summary: This is an open-label randomized controlled trial which will enroll patients with S. aureus bacteremia who are already taking aspirin for secondary prevention of cardiovascular events. We will randomize patients to continue their aspirin or change clopidogrel which is also approved for secondary prevention. Unlike aspirin, clopidogrel may have activity against S. aureus. We wish to determine if ch...

Summary: This project aims to evaluate the safety and efficacy of the antiplatelet regimen combining indobufen and clopidogrel in preventing ischemic events after stent-assisted coiling embolization and flow diverter implantation for intracranial aneurysms. Using a randomization system, patients with unruptured intracranial aneurysms scheduled for interventional treatment will be divided into an experiment...

Summary: Mitral regurgitation (MR) is the most common valvular heart disease, affecting approximately 24.2 million people worldwide (with a higher prevalence in older age groups). Transcatheter edge-to-edge repair (TEER) is now a well-established strategy in high-risk patients with MR. Globally, over 250,000 patients have benefited from the TEER technique. However, no dedicated study has prospectively eval...

Summary: Two strategies have both proven to be effective in reducing bleeding complications while preserving efficacy compared with maintaining long-term DAPT with aspirin and a potent P2Y12 inhibitor: a) DAPT de-escalation (i.e., switching from prasugrel or ticagrelor to clopidogrel while maintaining aspirin) and b) potent P2Y12 inhibitor monotherapy (i.e., maintaining prasugrel or ticagrelor and dropping...

Transcatheter edge-to-edge repair (TEER) is now a well-established strategy in high-risk patients with MR. Globally, over 250,000 patients have benefited from the TEER technique.Studies have shown that patients with severe mitral...

Summary: APICES trial is an investigator-initiated, multicenter, multicenter, randomized, double-blind, placebo-controlled clinical trial that plans to enroll 396 patients with a 1-year follow-up, including a neurovascular imaging examination \[digital subtraction angiography (DSA), CT angiography (CTA) or magnetic resonance angiography (MRA)\] at 6 months after index treatment. It was designed in complian...
