Background Combination antiplatelet therapy with clopidogrel and aspirin may reduce the rate of recurrent stroke during the first 3 months after a minor ischemic stroke or transient ischemic attack (TIA). A trial of combination antiplatelet therapy in a Chinese population has shown a reduction in the risk of recurrent stroke. We tested this combination in an international population. Methods In a randomized trial, we assigned patients with minor ischemic stroke or high-risk TIA to receive either clopidogrel at a loading dose of 600 mg on day 1, followed by 75 mg per day, plus aspirin (at a dose of 50 to 325 mg per day) or the same range of doses of aspirin alone...

Background: Based on the results of a recent randomized controlled trial, carotid artery stenting (CAS) was regarded as a relatively safe, less invasive treatment of internal carotid artery stenosis. However, cerebral thromboembolic events are the most common complications of CAS. Especially acute stent thrombosis following CAS will be fatal without prompt diagnosis and revascularization. Case Report: We report a case of acute stent thrombosis in whom carotid revascularization was performed successfully via arterial thrombolysis and balloon postdilation...

BACKGROUND : Switching between different classes of P2Y12 inhibitors, including de-escalation from ticagrelor to clopidogrel, commonly occurs in clinical practice. However, the pharmacodynamic profiles of this strategy have been poorly explored. METHODS : This was a prospective, randomized, open-label study conducted in patients on maintenance dosing (MD) of aspirin (81 mg/d) and clopidogrel (75 mg/d). After a 7-day run-in with ticagrelor (180 mg loading dose [LD] followed by 90 mg twice daily MD), patients (n=80) were randomized into 1 of 4 groups: group A, clopidogrel 600 mg LD 24 hours after the last MD of ticagrelor (C-600 mg-24h); group B, clopidogrel 600 mg LD 12 hours after the last MD of ticagrelor (C-600 mg-12h); group C, clopidogrel 75 mg/d MD 24 hours after the last MD of ticagrelor (C-75 mg-24h); and group D, ticagrelor 90 mg twice daily MD (T-90 mg twice daily)...

Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor is a mainstay of the prevention of stent thrombosis following percutaneous coronary intervention (PCI). In the 2015 European guidelines for the management of acute coronary syndrome (ACS), prasugrel (PRA) and ticagrelor (TICA) combined with aspirin are recommended as first-line therapy. Clopidogrel (CLO) is recommended as an alternative medication for patients with contradictions to these new drugs. This single-center study analyzed the platelet function of 809 ACS patients undergoing PCI and treatment with DAPT...

CD34+ cells expressing KDR (CD34+ /KDR+ ) represent a small proportion of circulating progenitor cells that have the capacity to interact with platelets and to differentiate into mature endothelial cells, thus contributing to vascular homeostasis and regeneration as well as to re-endothelialization. We investigated the levels of CD34+ and CD34+ /KDR+ progenitor cells as well as their interaction with platelets in acute coronary syndrome (ACS) patients before the initiation (baseline) of their treatment with a P2Y12 receptor antagonist, and at 5-days post-treatment (follow-up)...

In patients at high risk for bleeding undergoing percutaneous coronary intervention (PCI) the use of bare-metal-stent (BMS) is considered an option that allows discontinuation of clopidogrel after 4 weeks. We sought to investigate the risk of early discontinuation of clopidogrel in patients with BMS as compared with a 6-month course of clopidogrel after DES in patients with or without high on-treatment platelet reactivity (HTPR). In 765 consecutive patients undergoing PCI after loading with clopidogrel 600 mg, HTPR was tested by optical aggregometry and defined as residual platelet reactivity > 14%...
