Relationship Between p.R4810K and Echocardiographic Findings in Patients with Cerebrovascular Diseases: A Multicenter Prospective Cohort Study.

Background: RING finger protein 213 () p.R4810K is an established risk factor for moyamoya disease and intracranial artery stenosis in East Asian people. Recent evidence suggests its potential association with extracranial cardiovascular diseases, including pulmonary hypertension.

Detrimental Effect of Acute Hyperglycemia on the Outcomes of Large Ischemic Region Stroke.

Background: Although endovascular therapy (EVT) is effective for large ischemic region strokes, the impact of hyperglycemia remains unclear.

Methods And Results: We analyzed data from the RESCUE-Japan LIMIT (Recovery by Endovascular Salvage for Cerebral Ultra-Acute Embolism-Japan Large Ischemic Core) trial, which randomized stroke patients with Alberta Stroke Program Early Computed Tomography Score of 3 to 5 to EVT versus medical management. Outcomes were compared among patients with normoglycemia (<140 mg/dL), moderate hyperglycemia (≥140, <180 mg/dL), and severe hyperglycemia (≥180 mg/dL) on admission.

Intravenous Thrombolysis With Alteplase at 0.6 mg/kg in Patients With Ischemic Stroke Taking Direct Oral Anticoagulants.

Background We elucidated the safety of treatment with alteplase at 0.6 mg/kg within 24 hours for patients on direct oral anticoagulants (DOACs) before ischemic stroke onset. Methods and Results Consecutive patients with acute ischemic stroke who underwent intravenous thrombolysis using alteplase at 0.

Mechanical Thrombectomy Up to 24 Hours in Large Vessel Occlusions and Infarct Velocity Assessment.

Background We retrospectively compared early- (<6 hours) versus late- (6-24 hours) presenting patients using perfusion-weighted imaging selection and evaluated clinical/radiographic outcomes. Methods and Results Large vessel occlusion patients treated with mechanical thrombectomy from August 2017 to July 2020 within 24 hours of onset were retrieved from a single-center database. Perfusion-weighted imaging was analyzed by automated software and final infarct volume was measured semi-automatically within 14 days.

Effect of Heart Rate Variabilities on Outcome After Acute Intracerebral Hemorrhage: A Post Hoc Analysis of ATACH-2.

Background To explore how the clinical impact of heart rate (HR) and heart rate variabilities (HRV) during the initial 24 hours after acute intracerebral hemorrhage (ICH) contribute to worse clinical outcomes. Methods and Results In the ATACH-2 (Antihypertensive Treatment in Intracerebral Hemorrhage 2) trial, the HR was recorded for every 15 minutes from baseline to 1 hour and hourly during the initial 24 hours post-randomization. We calculated the following: mean, standard deviation, coefficient of variation, successive variation, and average real variability (ARV).

Use of Diffusion-Weighted Imaging-Alberta Stroke Program Early Computed Tomography Score (DWI-ASPECTS) and Ischemic Core Volume to Determine the Malignant Profile in Acute Stroke.

Background Malignant profiles were identified by imaging profiles and unfavorable outcomes that have poor response to reperfusion therapy. Many trials have used this profile in their inclusion criteria including large-vessel occlusion acute ischemic stroke trials. We aimed to redefine the cutoff values for malignant profile in acute ischemic stroke patients with large-vessel occlusion regardless of reperfusion therapy.
