Background and Purpose— The TST trial (Treat Stroke to Target) evaluated the benefit of targeting a LDL (low-density lipoprotein) cholesterol of <70 mg/dL to reduce the risk of cardiovascular events in 2860 patients with ischemic stroke with atherosclerotic stenosis of cerebral vasculature or aortic arch plaque >4 mm, in a French and Korean population. The follow-up lasted a median of 5.3 years in French patients (similar to the median follow-up time in the SPARCL trial [Stroke Prevention

BACKGROUND: Clinical and radiological characteristics of middle cerebral artery (MCA) infarction may differ according to the location of occlusion. OBJECTIVES: We investigated the difference between proximal and distal symptomatic MCA occlusion (MCAO) in patients with ischemic stroke. The factors associated with the imaging characteristics were also analyzed. METHODS: Patients with ischemic stroke due to MCAO were consecutively enrolled. The location of MCAO was determined by the ratio of the le

Background and Purpose: Although statins are effective in secondary prevention of ischemic stroke, they are also associated with an increase risk of intracranial hemorrhage (ICH) in certain conditions. In the TST trial (Treat Stroke to Target), we prespecified an exploration of the predictors of incident ICH. Methods: Patients with ischemic stroke in the previous 3 months or transient ischemic attack within the previous 15 days and evidence of cerebrovascular or coronary artery atherosclerosis w

BACKGROUND: Whether a strategy to target an LDL (low-density lipoprotein) cholesterol <70 mg/dL is more effective when LDL is reduced >50% from baseline rather than <50% from baseline has not been investigated. METHODS: The Treat Stroke to Target trial was conducted in France and South Korea in 61 sites between March 2010 and December 2018. Patients with ischemic stroke in the previous 3 months or transient ischemic attack within the previous 15 days and evidence of cerebrovascular or c

Recurrent stroke due to ECAS was more strongly associated with HAPR and insufficient antiplatelet inhibition than was that due to ICAS. Artery-to-artery embolism was associated with HAPR in recurrent ischemic stroke as a result of ICAS or ECAS.

Wearable devices may be used to evaluate sleep in patients with obstructive sleep apnoea (OSA). This study compared the use of two wearable devices (the Fitbit Charge 2 (FC2) and Galaxy Watch 2 (GW2)) with that of polysomnography (PSG) for assessing the sleep time of OSA patients. A total of 127 consecutive patients with OSA underwent overnight PSG while wearing the FC2 and GW2 on their nondominant wrist. We compared the total sleep time (TST) determined by the devices with that obtained by PSG

Patent foramen ovale (PFO) is the most common congenital cardiac deformity which is found in about 25% of general population and with a higher incidence of 50% in those with cryptogenic stroke patients. Right-to-left shunting through the PFO (paradoxical embolism) was regarded as the pathomechanism causing ischemic stroke (PFO-stroke). PFO-stoke more appeared as a small cortical lesion in the posterior circulation with less conventional risk factors. Large PFO with more shunting or a coexisting

Background and Purpose Ischemic stroke recurs despite the use of antiplatelet agents. Various mechanisms are involved in recurrence due to intracranial atherosclerosis (ICAS) and extracranial atherosclerosis (ECAS). High-on-aspirin platelet reactivity (HAPR) may differ between recurrent stroke due to ICAS and ECAS. Methods Patients with recurrent ischemic stroke as a result of large-artery atherosclerosis despite taking aspirin were enrolled consecutively. Ischemic stroke was classified as strok

Background/Objectives: The paretic wrist after stroke may exhibit median nerve conduction abnormalities, but factors underlying hemiplegic–contralateral asymmetry remain uncertain. We compared electrodiagnostic and ultrasonographic wrist measures between sides and assessed predictors of side-to-side differences in distal motor latency (ΔDML) and distal sensory latency (ΔDSL). Methods: We retrospectively analyzed 85 patients with stroke. Distal motor latency (DML), distal sensory latency (DSL), w
