Prevalence and Risk Factors of Cerebral Microbleeds in Patients with Nonvalvular Atrial Fibrillation: An Enhanced T2*-Weighted Angiography Imaging Study

Conclusion: The present data demonstrated that CMBs were associated with age, hypertension, warfarin treatment, smoking, and a history of ICH. We also found neither CHA2DS2-VASc score nor HAS-BLED score was associated with CMBs in patients with NVAF.Eur Neurol

Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this techniqu...

A 60-something presented with hypotension, bradycardia, chest pain and back pain.She had a h/o aortic aneurysm, aortic insufficiency, peripheral vascular disease, and hypertension.  She had a mechanical aortic valve.  She was on anti-hypertensives including atenolol, and on coumadin, with an INR of 2.3. She was ill appearing.  BP was 70/49, pulse 60.A bedside echo showed good ejection fraction and normal right ventricle and no pericardial fluid. Here is the initial ECG:What do you think?This ECG actually looks like a left main occlusion (which rarely presents to the ED alive):  ST Elevation in...

Authors: Enomoto Y, Hashimoto G, Sahara N, Hashimoto H, Niikura H, Nakamura K, Iijima R, Hara H, Suzuki M, Noro M, Moroi M, Sugi K, Nakamura M Abstract A 70-years-old male with a history of hypertension and drug resistant paroxysmal atrial fibrillation (AF) presented to our hospital for catheter ablation to his symptomatic AF. He had no prior surgical or percutaneous procedure to close or exclude the left atrial appendage (LAA). A transesophageal echocardiography (TEE) was performed to rule out intra-cardiac thrombus prior to the ablation procedure. Although the TEE imaging at multiple acquisition angles was obtain...

Authors: Olbers J, Gille A, Ljungman P, Rosenqvist M, Östergren J, Witt N Abstract PURPOSE: Atrial fibrillation (AF) is associated with an increased risk for cardiovascular morbidity and mortality, not entirely explained by thromboembolism. The underlying mechanisms for this association are largely unknown. Similarly, high blood pressure (BP) increases the risk for cardiovascular events. Despite this the interplay between AF and BP is insufficiently studied. The purpose of this study was to examine and quantify the beat-to-beat blood pressure variability in patients with AF in comparison to a control group of ...

AbstractBackground and purposeThe clinical benefit of endovascular stroke therapy has been demonstrated in several prospective randomized trials. However, in a relevant percentage of patients, mechanical thrombectomy bears the risk of causing new infarction in initially unaffected vascular territories through thrombus fragmentation and migration of clot debris. The goal of this study was to evaluate the use of the balloon guide catheter (BGC) to effectively achieve flow arrest and thrombus aspiration during the intervention to avoid distal embolization.MethodsA retrospective study was performed in 139 patients between Octo...

Authors: Bildirici U, Celikyurt U, Yavuz S, Dervis E, Adina Q, Ural D Abstract BACKGROUND Acute limb ischemia (ALI) is a clinical entity with a high rate of morbidity and mortality. Despite advances and variety of its management, there is still no criterion standard treatment. The goal of this study was to evaluate the effect of tirofiban use on the early and 6-month prognosis of patients with knee and below-knee arterial thrombosis who were treated with percutaneous thrombosuction (PT) within 24 h. MATERIAL AND METHODS Data of consecutive ALI patients who were diagnosed with popliteal and infra-popliteal arterial ...
