Renal Impairment Is Associated with Intracerebral Hemorrhage after Mechanical Thrombectomy in Vertebrobasilar Stroke

2018

<b><i>Background and Purpose:</i></b> Renal dysfunction (RD) is overall associated with unfavorable functional outcome and higher risk of mortality after acute ischemic stroke. Associations between RD and outcome in patients with acute vertebrobasilar stroke treated with thrombectomy have not been evaluated so far. <b><i>Materials and Methods:</i></b> Consecutive patients with vertebrobasilar stroke treated with mechanical thrombectomy between October 2010 and July 2017 at our center were analyzed. RD was defined as glomerular filtration rate (GFR) < 60 mL/min/1.73 m<sup>2</sup> at admission. Endpoints were (I) poor clinic…

Effects of clinical and laboratory variables at admission and of in-hospital treatment with cardiovascular drugs on short term prognosis of ischemic …

2011

Abstract Introduction No information exists, to our knowledge, about the possible role of cardiovascular drug administration in the acute phase of ischemic stroke and possible effects on stroke outcome. The aim of our study was to evaluate the relationship between in-hospital treatment with cardiovascular drugs in patients with acute ischemic stroke and some outcome indicators. Methods and Results 1096 subjects enrolled in the GIFA study, who had a main discharge diagnosis of ischemic stroke represent the final sample. Drugs considered for the analysis were the following: ACE-inhibitors (ACEI), angiotensin II receptor blockers (ARBs), statins, calcium-channel-blockers (CCBs), antiplatelet (…

Frequency and determinants for hemorrhagic transformation of cerebral infarction.

2009

<i>Background:</i> Frequency and associated risk factors for hemorrhagic transformation (HT), a worrying complication of ischemic stroke (IS), are not clearly defined. Our aim was to estimate the overall frequency and risk factors for HT in a hospital-based population. <i>Methods:</i> A retrospective review of medical records of patients discharged from our department during the period 2004–2006 with a diagnosis of anterior IS. Demographic, clinical and hematological information was collected. Uni- and multivariate logistic regression analyses were used to estimate risk for spontaneous HT. <i>Results:</i> We included 240 patients (125 males, 52%), mean ag…

Long‐Term Risk of Myocardial Infarction Compared to Recurrent Stroke After Transient Ischemic Attack and Ischemic Stroke: Systematic Review and Meta‐…

2018

Background Uncertainties remain about the current risk of myocardial infarction ( MI ) after ischemic stroke or transient ischemic attack. Methods and Results We undertook a systematic review to estimate the long‐term risk of MI , compared to recurrent stroke, with temporal trends in ischemic stroke/transient ischemic attack patients. Annual risks and 95% confidence intervals (95% CI ) of MI and recurrent stroke were estimated using random‐effect meta‐analyses. We calculated incidence ratios of MI /recurrent stroke, for fatal and nonfatal events, using similar analyses. Rate ratios for MI in patients with potential risk factors compared to those without were calculated using Poisson regres…

Electromyographic comparison of conventional machine strength training versus bodyweight exercises in patients with chronic stroke

2017

OBJECTIVE: To investigate whether bodyweight exercises can induce comparable levels of muscle activity as conventional machine exercises in chronic stroke patients.METHODS: Eighteen patients performed three repetitions of bilateral- and unilateral machine leg press and the bodyweight exercises chair rise and hip thrust. Surface electromyography (EMG) was recorded from 10 lower extremity muscles and normalized to maximal EMG (nEMG) of the non-paretic leg.RESULTS: For the paretic leg, the bodyweight exercises showed comparable levels of nEMG in 6 out of 10 muscles compared with the bilateral leg press. Vastus lateralis nEMG was higher during bilateral leg press compared with hip thrust (38% […

Systematic monitoring for detection of atrial fibrillation in patients with acute ischaemic stroke (MonDAFIS): a randomised, open-label, multicentre …

2021

Summary Background Systematic electrocardiogram (ECG) monitoring improves detection of covert atrial fibrillation in stroke survivors but the effect on secondary prevention is unknown. We aimed to assess the effect of systematic ECG monitoring of patients in hospital on the rate of oral anticoagulant use after 12 months. Methods In this investigator-initiated, randomised, open-label, parallel-group multicentre study with masked endpoint adjudication, we recruited patients aged at least 18 years with acute ischaemic stroke or transient ischaemic attack without known atrial fibrillation in 38 certified stroke units in Germany. Patients were randomly assigned (1:1) to usual diagnostic procedur…

Echocardiographic and lung ultrasound characteristics in ambulatory patients with dyspnea or prior heart failure.

2013

Purpose Lung ultrasound (LUS) represents a novel, noninvasive method in the assessment of extravascular lung water. We investigated the utility of LUS in ambulatory subjects with dyspnea or prior heart failure (HF). Methods We studied 81 ambulatory subjects with HF history or dyspnea who underwent transthoracic echocardiography (TTE) with LUS of 8 zones. Subjects with heart transplantation or pulmonary conditions known to interfere with LUS were excluded. A reviewer blinded to the clinical data performed echocardiographic measurements and quantified B-lines (reverberation artifacts arising from the pleural line). Results Of 81 subjects, 74 (91%) (median age 66 years, 39% men, median left ve…

Spontaneous splenic rupture after thrombolysis for ischemic stroke.

2015

Spontaneous spleen rupture with no recent report of trauma is an extremely rare and life-threatening cause of intraperitoneal hemorrhage.We present the first case of an atraumatic pathological splenic rupture following alteplase thrombolysis for ischemic stroke.

Insight into the molecular sex dimorphism of ischaemic stroke in rat cerebral cortex: Focus on neuroglobin, sex steroids and autophagy

2020

Including sex is of paramount importance in preclinical and clinical stroke researches, and molecular studies dealing in depth with sex differences in stroke pathophysiology are needed. To gain insight into the molecular sex dimorphism of ischaemic stroke in rat cerebral cortex, male and female adult rats were subjected to transient middle cerebral artery occlusion. The expression of neuroglobin (Ngb) and other functionally related molecules involved in sex steroid signalling (oestrogen and androgen receptors), steroidogenesis (StAR, TSPO and aromatase) and autophagic activity (LC3B-II/LC3B-I ratio, UCP2 and HIF-1 alpha) was assessed in the ipsilateral ischaemic and contralateral non-ischae…
