BACKGROUND Subclavian artery stenosis (SAS) is narrowing of the subclavian artery most commonly caused by atherosclerosis. It serves as a marker for cerebrovascular and myocardial ischemic events. METHODS A retrospective cohort study was conducted to determine the association of treatment via combination therapy (antiplatelet drug plus either by-pass surgery or percutaneous transluminal angio...

www.thelancet.com Published online June 13, 2017 http://dx.doi.org/10.1016/S0140-6736(17)31507-6 1 Antiplatelet therapy is the most frequently recommended treatment to prevent recurrent ischaemic events in patients who have had an ischaemic stroke, an acute coronary syndrome, or symptomatic peripheral arterial disease. The most frequently used drugs are aspirin or clopidogrel. Most guidelines r...

Platelet activation and aggregation are considered to be central to arterial thrombus formation. Antiplatelet therapy is therefore important for both the treatment and prevention of cardiovascular disease. Aspirin, the most widely used antiplatelet agent, inhibits platelet cyclo-oxygenase and the conversion of arachidonic acid to the potent platelet agonist thromboxane A(2) but does not prevent...

BACKGROUND AND PURPOSE Thromboembolic events are the most common complications of elective coil embolization of cerebral aneurysms. Administration of oral clopidogrel and/or aspirin could lower the thromboembolic complication rate. MATERIALS AND METHODS Records over a 10-year period were reviewed in a retrospective cohort study. For 369 consecutive elective coil embolization procedures, 25 pa...

Clear evidence supports the value of oral anticoagulation (OAC) with vitamin K antagonists in preventing stroke and thromboembolism in patients with atrial fibrillation (AF) who have well-established risk factors. For this indication, vitamin K antagonists have been shown to be superior to single or dual antiplatelet agents in reducing thromboembolic complications (1). Yet, up to 30% of patient...

The purpose of this study is to evaluate the effect of adding cilostazol to dual antiplatelet therapy (aspirin and thienopyridine) on rates of restenosis after coronary artery stenting. A meta-analysis is conducted of randomized, controlled trials comparing 3 drug regimens (cilostazol, thienopyridine, aspirin [triple therapy]) with dual antiplatelet therapy to reduce restenosis after coronary s...

The substantial reduction in ischemic events provided by the dual antiplatelet regimen with aspirin and clopidogrel is well documented in patients with acute coronary syndrome and patients undergoing percutaneous coronary intervention. Recently the variable response to the antiplatelet agents has received considerable attention after several "boxed warnings" on clopidogrel. This led to intense ...

OBJECTIVE To evaluate whether concomitant treatment with low-dose aspirin or other antiplatelet agents have an impact on the risk of severe ischemic complications and in the outcome of patients with giant cell arteritis (GCA). METHODS A retrospective follow-up study of an unselected population of 121 patients with GCA. RESULTS Thirty-seven patients (30.5%) received antiplatelet therapy befo...

BACKGROUND guidelines have changed in relation to the indication of antiplatelet therapy for the primary and secondary prevention of stroke. Of interest is how the proportion of patients who had or had not taken antiplatelet agents prior to an incident stroke has changed over time, whether the type of antiplatelet agents used has altered and whether prior antiplatelet use is associated with a p...

Worldwide, cardiovascular events represent the major cause of morbidity and mortality. A key role in the pathogenesis of these events is played by platelets. Interventional procedures, with placement of coronary and vascular stents, often represent the preferred therapeutic strategy. Antiplatelet medications are considered first-line therapy in preventing cardiovascular thrombotic events. A wid...
