BACKGROUND: The association of platelet reactivity and clinical outcomes, especially stent thrombosis, was not so clear. We sought to investigate whether high platelet reactivity affects clinical outcomes of patients with drug eluting stents (DESs) implantation. METHODS: All enrolled individuals treated with DESs implantation were evaluated by PL-11, using sequentially platelet counting method. The primary end point was the occurrence of definite and probable stent thrombosis at 2 years...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has been adopted worldwide as the standard treatment for severe aortic stenosis in symptomatic patients at prohibitive or high surgical risk, but there are still several areas where consensus and evidence are lacking. The purpose was to obtain a global view of current practice related to TAVI with the potential to identify the main areas of consensus and divergence between centers. METHODS: An online questionnaire was distributed in centers performing TAVI including a total of 59 questions concerning pre-procedural evaluation, procedural practices and post-procedural management...

BACKGROUND: After myocardial infarction (MI) treated with percutaneous coronary intervention (PCI), guidelines recommend dual antiplatelet therapy (DAPT) with aspirin and an ADP receptor inhibitor (ADPri) for at least 1year. However, whether real-world Canadian practice patterns reflect this recommendation is unknown. METHODS: We studied 2175 MI patients treated with PCI and discharged from 26 Canadian hospitals between 12/2011 and 05/2013 in the Canadian Observational Antiplatelet sTudy (COAPT)...

Left atrial appendage (LAA) dimensions have been shown as an independent predictor of higher risk for stroke in AF patients. Little data exist on the outcomes after LAA closure in patients with nonvalvular atrial fibrillation (NVAF) who have relatively bigger LAA size. This study aims to evaluate the results associated with LAA closure with the Amplatzer cardiac plug (ACP, AGA, St. Jude Medical, Minneapolis, MN) in bigger LAA size. A total of 25 patients with NVAF underwent LAA closure with the ACP device. All patients received short-term (up to 3 months) dual-antiplatelet therapy (clopidogrel and aspirin) after the procedure and aspirin only thereafter...

Scarce and conflicting evidence exists on whether clopidogrel is effective and whether dual antiplatelet treatment (DAPT) is safe in patients with acute coronary syndrome and chronic kidney disease (CKD). To study this, we performed an observational, prospective, multicenter cohort study of 36,001 patients of the SWEDEHEART registry. The exposure was DAPT prolonged after 3 months versus DAPT stopped at 3 months in consecutive patients with acute coronary syndrome and known serum creatinine. DAPT duration with clopidogrel and aspirin was assessed by dispensed tablets...

Acetylsalicylic acid and clopidogrel combined therapy has been reported to be beneficial in patients with acute coronary syndrome (ACS). Antiplatelet drug resistance, especially to clopidogrel, is a multifactorial phenomenon that affects a large number of ACS patients. The genetic contribution to this drug response is not fully elucidated. We investigated the relationship of ABC-type efflux subfamily C member 3 (ABCC3) polymorphisms and mRNA expression with plasma concentrations of clopidogrel, salicylic acid (SA), and a carboxylic acid metabolite (CAM)...

BACKGROUND: After transcatheter aortic valve implantation, early leaflet thickening, presumably reflecting thrombus, has recently been described on computed tomography angiography (CTA) in ~10% of the patients. We sought to investigate the impact of the antithrombotic regimen on the course of leaflet thickening. METHODS: The study comprised 51 patients with leaflet thickening. Based on the time period, patients without an established indication for anticoagulation were put on phenprocoumon plus clopidogrel for at least 3 months or on dual antiplatelet therapy with aspirin and clopidogrel...

Dual anti-platelet therapy denotes a regimen of aspirin plus a P2Y12 receptor inhibitor, clopidogrel, prasugrel, or ticagrelor. Such therapy is a cornerstone of medical management following acute coronary syndromes and is imperative following percutaneous coronary interventions. While there is uncertainty about the optimal duration of dual antiplatelet therapy following percutaneous coronary intervention, the new 2016 American College of Cardiology/American Heart Association Guidelines suggest that for patients with stable ischemic heart disease at least six months of such therapy following a drug eluting stent and one month following a bare metal stent should be implemented...

INTRODUCTION: The incidence of recurrent carotid stenosis after carotid endarterectomy varies from 1% to 37% with only 0-8% symptomatic restenosis. Safety of short-term (30 days) dual-antiplatelet therapy has not been established in this type of procedure. AIMS: To investigate the safety of dual antiplatelet therapy after carotid endarterectomy to prevent restenosis. METHODS: We retrospectively identified all the patients who underwent carotid endarterectomy (symptomatic or asymptomatic) treated at our center between July 2010 and July 2013 according to local protocols...

Despite the application of new antiplatelet drugs (prasugrel and ticagrelor), dual antiplatelet therapy with clopidogrel and aspirin remains the standard for patients with acute coronary syndrome undergoing percutaneous coronary intervention, especially in countries of low socioeconomic status. Regardless of the proven benefits, numerous studies have shown that certain groups of patients who receive standard doses of clopidogrel and aspirin do not respond adequately, and many of them also exhibit adverse cardiovascular events...

Patients who have had a stroke are at high risk for recurrent stroke, myocardial infarction, and vascular death. Prevention of these events should be initiated promptly after stroke, because many recurrent events occur early, and should be tailored to the precise cause of stroke, which may require specific treatment. Lifestyle advice including abstinence from smoking, regular exercise, Mediterranean-style diet, and reduction of salt intake and alcohol consumption are recommended for all patients with stroke...

BACKGROUND: The risk of recurrence following ischemic stroke or transient ischemic attack is highest immediately after the event. Antiplatelet agents are effective in reducing the risk of recurrence and two agents are superior to one in the early phase after ictus. DESIGN: The triple antiplatelets for reducing dependency after ischemic stroke trial was an international multicenter prospective randomized open-label blinded-endpoint trial that assessed the safety and efficacy of short-term intensive antiplatelet therapy with three agents (combined aspirin, clopidogrel and dipyridamole) as compared with guideline treatment in acute ischemic stroke or transient ischemic attack...

Due to the rising prevalence of coronary heart disease, endoscopists are more frequently performing a polypectomy in patients on antiplatelet therapy (APT) and dual antiplatelet therapy (DATP). Despite the availability of several guidelines with regard to the management of antiplatelet drugs during the periprocedure period, there is still variability in the current clinical practice. This may be influenced by the low quality of the evidence supporting recommendations, because most of the studies dealing with APT and polypectomy are observational and retrospective, and include mainly small (< 10 mm) polyps...
