Long Term Mortality

Background: Cerebral microbleeds (CMBs) were predictive of mortality in elderly and considered as a putative marker for risk of intracranial hemorrhage. Stroke patients with non valvular atrial fibrillation (NVAF) require anticoagulation, which increases the risk of hemorrhages. We investigated association of CMBs with the long term mortality in acute ischemic stroke patients with NVAF. Methods: During 6 years , consecutive ischemic stroke patients who had NVAF and who had undergone brain MRI with a gradient-recalled echo sequence were enrolled. Long-term mortality and causes of death were identified using data from Korean National Statistical Office. Survival analysis was performed whether the presence, number and location of CMBs were related with all causes, cardiovascular, and cerebrovascular mortality during follow-up. Results: Total 506 patients were enrolled during the study period and were followed up for median 2.5 years. CMBs were found in 30.8% of patients (156/506). Oral anticoagulation with warfarin was prescribed at discharge in 477 (82.7%) patients. During follow up, 177 (35%) patients died and cerebrovascular death was noted in 93 patients (81 ischemic stroke and 12 hemorrhagic stroke). After adjusting age, sex and significant variables in univariate analysis (p<0.1), multiple CMBs (≥5) were the independent predictor for all-cause, cardiovascular and ischemic stroke mortalities. The strictly lobar CMBs were associated with hemorrhagic stroke mortality in multivariate Cox regression analysis (HR 4.776, p=0.032) (Figure 1). Conclusions: Multiple CMBs were the independent predictor for the long term mortality in stroke patients with NVAF. Among them, patients with strictly lobar CMBs had a high risk of death due to hemorrhagic stroke. Our findings suggest that detection of CMBs in stroke patients with NVAF are of clinical relevance for predicting long term outcome and that particular concern is necessary in those with strictly lobar CMBs for their increased risk of death due to hemorrhagic stroke.

Abstract Background The treatment of acute ischemic stroke is heavily time-dependent, and even though, with the most efficient treatment, the long-term functional outcome is still highly variable. In this current study, the authors selected acute ischemic stroke patients who were qualified for intravenous thrombolysis with recombinant tissue plasminogen activator and followed by intra-arterial thrombectomy. With primary outcome defined by the functional level in a one-year follow-up, we hypothesize that patients with older age are at a disadvantage in post-stroke recovery. However, an age-threshold should be determined to help clinicians in selection of patients to undergo such therapy. Methods This is a retrospective chart review study that include 92 stroke patients in Changhua Christian hospital with a total of 68 evaluation indexes recorded. The current study utilized the forward stepwise regression model whose Adj-R2 and p-value in search of important variables for outcome prediction. The chngpt package in R indicated the threshold point of the age factor directing the better future functionality of the stroke patients. Results Datasets revealed the threshold of the age set at 79 the most appropriate. Admission Barthel Index, Age, Ipsi ICA RI, Ipsi VA PI, Contra MCA stenosis, Contra ECA RI, and in-hospital pneumonia are the significant predicting variables. The higher the age, in-hospital pneumonia, Contra MCA stenosis, Ipsi ICA RI and Ipsi VA PI, the less likely patient to recover from functional deficits as the result of acute ischemic stroke; the higher the value of Contra ECA RI and Admission Barthel Index, the better chance to recover at one-year follow up. Conclusions Parameters of pre-intervention datasets could provide important information to aid first-line clinicians in decision making. Especially, in patients whose age is above seventy-nine receives diminish return in the benefit to undergo such intervention and should be considered seriously by both the patients and the physicians.

Objectives: Endovascular treatment provides a therapeutic option for acute ischemic stroke patients who are ineligible for, or who do not respond to intravenous thrombolysis. Higher rates of recanalization by mechanical clot extraction device were reportedly associated with better clinical outcome, but the long-term patency of recanalized vessel is unknown. Methods: We retrospectively evaluated magnetic resonance angiography (MRA) at 24-hour and 3-month after the endovascular treatment in consecutive acute stroke patients who were treated with mechanical clot extraction device between Oct. 2010 and May 2012 in our institution. Results: Fourty-six patients received endovascular treatment for acute ischemic stroke and 35 were treated with mechanical clot extraction devices, Merci and/or Penumbra system, with or without adjunctive therapy. Mean age was 69±12 years, baseline median National Institutes of Health Stroke Scale score was 15 (8 to 24), and occluded vessels were the internal carotid artery in 34%, middle cerebral artery (MCA) in 54%, and vertebro-basilar artery in 11%. Successful recanalization, defined as Thrombolysis In Myocardial Infarction II or III perfusion, was obtained in 32 (91%) patients. During 24-hour after the treatment, reocclusion of the treated vessel was observed in 4 (12.5%) patients. Of 28 eligible patients, 21 (75%) patients had 3-month MRA follow-up. None of the patients had reocclusion, but clinically silent diffuse stenosis was observed in 2 (9.5%) patients. Statistically significant predictors were not identified, but both of the patients were MCA occlusion treated with Merci retriever. Conclusion: In this study, late stenosis was observed in the MCA on 3-month follow-up MRA. Long-term follow-up seems to be useful to follow the recanalized vessels, especialy when mechanical devices were used.

OBJECTIVEThe role of mechanical thrombectomy in pediatric acute ischemic stroke is uncertain, despite extensive evidence of benefit in adults. The existing literature consists of several recent small single-arm cohort studies, as well as multiple prior small case series and case reports. Published reports of pediatric cases have increased markedly since 2015, after the publication of the positive trials in adults. The recent AHA/ASA Scientific Statement on this issue was informed predominantly by pre-2015 case reports and identified several knowledge gaps, including how young a child may undergo thrombectomy. A repeat systematic review and meta-analysis is warranted to help guide therapeutic decisions and address gaps in knowledge.METHODSUsing PRISMA-IPD guidelines, the authors performed a systematic review of the literature from 1999 to April 2019 and individual patient data meta-analysis, with 2 independent reviewers. An additional series of 3 cases in adolescent males from one of the authors’ centers was also included. The primary outcomes were the rate of good long-term (mRS score 0–2 at final follow-up) and short-term (reduction in NIHSS score by ≥ 8 points or NIHSS score 0–1 at up to 24 hours post-thrombectomy) neurological outcomes following mechanical thrombectomy for acute ischemic stroke in patients < 18 years of age. The secondary outcome was the rate of successful angiographic recanalization (mTICI score 2b/3).RESULTSThe authors’ review yielded 113 cases of mechanical thrombectomy in 110 pediatric patients. Although complete follow-up data are not available for all patients, 87 of 96 (90.6%) had good long-term neurological outcomes (mRS score 0–2), 55 of 79 (69.6%) had good short-term neurological outcomes, and 86 of 98 (87.8%) had successful angiographic recanalization (mTICI score 2b/3). Death occurred in 2 patients and symptomatic intracranial hemorrhage in 1 patient. Sixteen published thrombectomy cases were identified in children < 5 years of age.CONCLUSIONSMechanical thrombectomy may be considered for acute ischemic stroke due to large vessel occlusion (ICA terminus, M1, basilar artery) in patients aged 1–18 years (Level C evidence; Class IIb recommendation). The existing evidence base is likely affected by selection and publication bias. A prospective multinational registry is recommended as the next investigative step.

Background and purpose: Atherosclerotic ischemic stroke is the second most frequent etiology of stroke in the adult population. Functional outcome, mortality and recurrence of stroke rates on the long-term follow-up are poorly studied. This study investigates long-term outcome among patients with ischemic stroke secondary to atherosclerotic causality, and identifies the main factors associated with poor outcome, recurrence, and death. Methods: We analyzed data from our consecutive acute ischemic stroke database, over a period of 25 years (1990-2015). The endpoints were: bad outcome (Modified Rankin Score ≥3), recurrence and mortality at discharge, and final follow-up. Multivariate Cox and Kaplan-Meier analysis were used to estimate the probability of death and recurrence. Results: A total of 946 consecutive atherosclerotic stroke patients were included (571 [60.4%] males, median age 65 years [interquartile range 57-73 years] for the entire population); dyslipidemia (64.2%), hypertension (63.3%), diabetes (35.0%), and active smoking history (31.8%) were the most prevalent risk factors.After a median follow-up of 38 months (IQR 12-75 months), 59.3% patients had a bad outcome at discharge. A result of 26.1% had stroke recurrence (median time until recurrence: 9 months [IQR 12-84 months], with 12.9% cases presenting ≥2 recurrences), and 24.1% were dead (median time to death: 18.5 months [IQR 11-74 months]) at the final follow-up period. After multivariate adjustment, hypertension (HR 4.2, CI 95% 2.8-6.1; p<0.001) was the strongest predictor of recurrence. Additionally, diabetes (HR 2.6, CI 95% 2.0-3.5; p<0.001), bad functional outcome after recurrence (HR 2.3, CI 95% 1.9-2.9; p<0.001), age ≥65 years (HR 2.2, CI 95% 1.7-2.9; p<0.001), and active smoking (HR 1.8, CI 95% 1.3-2.3; p<0.001) were the strongest predictors of mortality. Conclusions: Atherosclerotic ischemic stroke has a high rate of recurrence, associated mainly with hypertension. Mortality is predicted by diabetes, bad functional outcome at recurrence, and older age.
