The association between asymptomatic coronary artery disease and CHADS2 and CHA2DS2‐VASc scores in patients with stroke
ConclusionCHADS2 and CHA2DS2‐VASc scores were predictive of the presence and severity of CAD in patients with stroke. When a patient has high CHADS2 or CHA2DS2‐VASc scores, physicians should consider coronary artery evaluation.

Finding atrial fibrillation in stroke patients: Randomized evaluation of enhanced and prolonged Holter monitoring—Find-AFRANDOMISED —rationale and design
Background: Detecting paroxysmal atrial fibrillation (AF) in patients with ischemic strokes presenting in sinus rhythm is challenging because episodes are often short, occur randomly, and are frequently asymptomatic. If AF is detected, recurrent thromboembolism can be prevented efficiently by oral anticoagulation. Numerous uncontrolled studies using various electrocardiogram (ECG) devices have established that prolonged ECG monitoring increases the yield of AF detection, but most established procedures are time-consuming and costly. The few randomized trials are mostly limited to cryptogenic strokes. The optimal method, du...

Large artery occlusion diagnosed by computed tomography angiography in acute ischaemic stroke: Frequency, predictive factors, and safety
Conclusions Arterial occlusions are seen in 23.6% of patients, especially in those who are admitted during the first few hours. NIHSS score serves as a useful predictive factor.

Thrombus composition in acute ischemic stroke: A histopathological study of thrombus extracted by endovascular retrieval
Conclusion HAS was significantly associated with early phase thrombus composition. This may enable the prediction of thrombus composition and allow for targeted selection of therapeutic modality.

Stroke prevention following modified endoscopic ablation and appendectomy for atrial fibrillation
We reported the results of stroke prevention following modified endoscopic procedure for atrial fibrillation. 82 patients underwent modified endoscopic procedure for atrial fibrillation (AF), in whom 47 had paroxysmal, 28 had persistent, and 7 had long-standing atrial fibrillation. CHA2DS2VASC median score was 3 (range from 0 to 8). The procedure was performed on the beating heart, through 3 ports on the left chest wall. Pulmonary vein isolation and ablation of the left atrium were achieved by bipolar radiofrequency ablation. Left atrial appendage (LAA) was excluded by stapler. Brain CT, cardiac CT and 24-h Holter monitori...

Potential Utility of Multidetector Computed Tomography to Identify both Cardiac Embolic Sources and Coronary Artery Disease in Patients with Embolic Stroke
Conclusions: Our results suggest that MDCT has potential to identify both cardiac embolic sources and CAD in patients with embolic stroke but without known CAD.Cardiology 2016;133:205-210

Midbrain and bilateral paramedian thalamic stroke due to artery of Percheron occlusion
Conclusion Bilateral thalamic stroke due to artery of Percheron occlusion is a rare presentation of stroke, which can be overlooked in routine CT scan. If diagnosed, it requires further evaluation for stroke risk factors, especially cardiovascular disorders associated with increased embolic risk.

Early introduction of direct oral anticoagulants in cardioembolic stroke patients with non-valvular atrial fibrillation
AbstractDirect oral anticoagulants (DOACs) are superior to warfarin in reduction of the intracranial bleeding risk. The aim of the present study was to assess whether early DOAC introduction (1 –3 days after onset) in stroke patients with non-valvular atrial fibrillation (nVAF) may be safe and effective, compared with DOAC introduction after 4–7 days. We conducted a prospective analysis based on data collected from 147 consecutive nVAF patients who started DOAC within 7 days after stro ke onset. In all patients, we performed pre-DOAC CT scan 24–36 h after onset and follow-up CT scan at 7 days after DOAC introduction...

Abnormally high risk of stroke in Brugada syndrome
Background The present study sought to evaluate the incidence of cerebrovascular events in a large cohort of patients with Brugada syndrome (BrS) analysing possible predictors, clinical characteristics and prognosis of cardioembolic events secondary to atrial fibrillation. Methods A total of 671 consecutive patients (age 42.1 ± 17.0 years; men 63%) with a diagnosis of BrS were retrospectively analysed over a mean follow-up period of 10.8 ± 5.5 years. The diagnosis of ischemic stroke was made according to the AHA/ASA guidelines using computed tomography (CT) and angio-CT in the emergency department. Results ...

Relation of Left Atrial Appendage Morphology Determined by Computed Tomography to Prior Stroke or to Increased Risk of Stroke in Patients With Atrial Fibrillation
This study aimed to assess inter-observer and intra-observer agreements in LAA morphology and its real value in stroke prediction. A total of 2264 atrial fibrillation (AF) patients who underwent computed tomography (CT) to explore the LAA anatomy were enrolled.

Multimode Computed-Tomography-Guided Thrombolysis under a Prolonged Time Window in Acute Ischemic Stroke Patients with Atrial Fibrillation.
Authors: Yang Y, Sun W, Li D, Li XY, Wang XT, Li SC, Zhao HJ, Zhang JB Abstract Atrial fibrillation (AF) is an independent risk factor for intracranial hemorrhage in patients receiving recombinant-tissue-type plasminogen activator (rt-PA) thrombolytic therapy. Research showed that patients with acute ischemic stroke (AIS) could benefit from multimode computed-tomography- (CT-) guided intravenous thrombolysis over 4.5 hours. The medical data of patients with AIS in our center were retrospectively reviewed, and the data of the multimode CT-guided thrombolytic therapy or nonthrombolytic therapy within different time w...
