Remote Ischemic Perconditioning for the Treatment of Acute Ischemic Stroke
To the Editor We read with interest the article by Pico et al, who reported the results of a randomized clinical trial to determine whether remote ischemic perconditioning can reduce brain infarction volume growth in patients with acute ischemic stroke. In the study, treatment with remote ischemic perconditioning had no significant effect on brain infarction volume growth at 24 hours after symptom onset. Two main hypotheses were proposed for the neutral results: remote ischemic perconditioning may not have any beneficial effect, or this trial mainly recruited patients who had received reperfusion therapies. However, we con...

Endovascular Therapy for Childhood Stroke —Working Together to Reach Prime Time
The standard of care for stroke treatment in adults changed rapidly in 2015 after results from 5 major clinical trials each showed efficacy of endovascular treatment of anterior circulation large-vessel occlusion within 6 hours of stroke onset. The positive results of these studies have since raised questions about whether endovascular therapy should be used for children who present with stroke due to large-vessel occlusion and, other than age, fit adult criteria for thrombectomy. Compared with the occurrence in adults, ischemic stroke in children is uncommon, but remains important to address because the resulting disabili...

Realizing Benefits From More Intensive Blood Pressure Control for Preventing Recurrent Stroke
Blood pressure (BP) targets below 140/90 mm Hg in high-risk patients, such as those who have had a stroke, remain a controversial topic. A pivotal meta-analysis of 61 prospective observational studies involving 1 million adults without previous cardiovascular (CV) disease showed a linear association between usual BP levels and deaths from ischemic heart disease and stroke, down to BP levels as low as 115/75 mm Hg. These data prompted the “lower the better” hypothesis and challenged the long-standing argument of a J-curve or U-curve association of BP levels in such patients. Before the pivotal Systolic Blood Pressure In...

Presenting to Primary Stroke Centers for Thrombolysis
To the Editor The study by Gerschenfeld et al attempted to address the topical question of whether patients should be brought to a primary stroke center (PSC) for early thrombolysis or be directly transported, despite a longer traveling distance, to a comprehensive stroke center (CSC) that was capable of performing a mechanical thrombectomy (ME). The study found no difference in 24-hour, discharge, or 3-month outcomes between groups of those presenting to a PSC who received thrombolysis and transferred to a CSC for ME and those who presented first to CSC and received thrombolysis and ME. The study concludes “that patient...

Mechanical Thrombectomy in Acute Stroke —Reply
In Reply We read with interest the letter by Seners and colleagues regarding our recent publication. The possibility of early recanalization among patients with acute ischemic stroke and a proximal intracranial occlusion was underestimated in the recent trials on mechanical thrombectomy (MT) because vascular imaging was in part done after starting intravenous thrombolysis (IVT), particularly in the MR CLEAN trial. However, Seners et al observed higher recanalization rates for M1 and M2 occlusions at an early stage, but this was not the case for carotid occlusions. Additionally, they defined early recanalization as happenin...

Response to Endovascular Therapy for Acute Ischemic Stroke
To the Editor Recent data from randomized clinical trials provide clear evidence that endovascular treatment for acute ischemic stroke because of large vessel anterior circulation occlusion improves clinical outcomes for patients. These studies reported that most patients had an occlusion of the first segment (M1) of the middle cerebral artery and less than 10% in the M2 segment. The retrospective multicenter study conducted by Sarraj et al reports that endovascular treatment is safe and effective for an occlusion of the M2 segment. However, the literature reports different definitions for the M1 and M2 segments, which may...

Cardiovascular Risk Factors and Stroke in Alzheimer Disease
To the Editor I read with interest the article by Tosto et al studying the influence of cardiovascular risk factors and stroke in familial late-onset Alzheimer disease (LOAD). The main findings were that history of stroke increased the risk for LOAD, while hypertension decreased the risk for LOAD. The study suggests that stroke mediates the influence of cardiovascular risk factors on increased risk for LOAD.
