OBJECTIVE Atherosclerosis is believed to be a minor cause of TIA and stroke in younger and middle-aged patients. However, data from large cohorts are limited. This study investigates the prevalence of extracranial and intracranial atherosclerosis in stroke and TIA patients aged 18-55 years in the multinational sifap1 study. METHODS From the sifap1 cohort(More)
BACKGROUND AND PURPOSE The prevalence of ex vivo 'high on-treatment platelet reactivity' (HTPR) to antiplatelet regimens in patients with ischaemic cerebrovascular disease (CVD) is uncertain. METHODS HTPR was assessed with PFA-100 collagen-epinephrine (C-EPI) and collagen-ADP (C-ADP) cartridges. Platelet activation (CD62P, CD63 and leucocyte-platelet(More)
Pulmonary venous thromboembolism has only been identified as a cause of stroke with pulmonary arteriovenous malformations/fistulae, pulmonary neoplasia, transplantation or lobectomy, and following percutaneous radiofrequency ablation of pulmonary vein ostia in patients with atrial fibrillation. A 59-year-old man presented with a posterior circulation(More)
The impact of changing antiplatelet therapy on thrombin generation potential in patients with ischaemic cerebrovascular disease (CVD) is unclear. We assessed patients within 4 weeks of TIA or ischaemic stroke (baseline), and then 14 days (14d) and >90 days (90d) after altering antiplatelet therapy. Thrombin generation was assessed in platelet poor plasma.(More)
INTRODUCTION The importance of thrombin generation in the pathogenesis of TIA or stroke and its relationship with cerebral microembolic signals (MES) in asymptomatic and symptomatic carotid stenosis has not been comprehensively assessed. METHODS Plasma thrombin generation parameters from patients with moderate or severe (≥ 50%) asymptomatic carotid(More)
A 48-year-old man presented with a posterior circulation stroke secondary to left lateral medullary infarction. Contrast-enhanced magnetic resonance angiography (CEMRA) revealed 40-45% intracranial left vertebral artery stenosis, likely atherosclerotic in nature. CEMRA and subsequent computed tomography angiography also identified a duplicate origin of the(More)
INTRODUCTION Consistent adherence to treatment is essential for effective secondary prevention following TIA/ischaemic stroke. Representative data on long-term treatment continuation and adherence rates are limited. METHODS This single centre study recruited patients attending our Rapid Access Stroke Prevention clinic in Ireland from 07/09/2006 →(More)
The appropriateness of use and accuracy of age, blood pressure, clinical features and duration of symptoms (ABCD) scoring by non-stroke specialists while risk-stratifying patients with suspected transient ischaemic attack (TIA) are unknown. We reviewed all available ABCD data from referrals to a specialist neurovascular clinic. ABCD scoring was defined as(More)
We present a male-to-female (MTF) transgender patient admitted with a pulmonary embolism. The patient had been treated with high-dose oestrogens since the age of 16. Following a prolonged period of hypotension, our patient sustained cerebral border zone infarcts. There was evidence of bilateral carotid stenosis on Doppler ultrasound. We discuss the(More)
