AbstractSeveral studies have investigated the efficacy and safety outcomes of non-vitamin K antagonist oral anticoagulants (NOACs) versus warfarin in patients with atrial fibrillation (AF) and heart failure (HF). Herein, this meta-analysis was aimed to compare the effect of NOACs with warfarin in this population. We systematically searched the PubMed database until December 2019 for studies that compared the effect of NOACs with warfarin in patients with AF and HF. Risk ratios (RRs) and 95% confidence intervals (CIs) were abstracted and then pooled using a random-effects model. A total of nine studies were included in this...

ConclusionsStroke or stroke-like syndrome of infectious origin can be observed in an important proportion of case presenting with sensory-motor deficit of unknown origin; their accurate diagnosis has a considerable impact in terms of treatment choices and outcome.

Intracerebral hemorrhage (ICH) is a severe cerebrovascular disease with a high incidence, mortality and disability rate. Danhong injection (DHI) is beneficial for ischemic stroke, but is prohibited for ICH due to risk of bleeding. The present study aims to explore the potential therapeutic time window and molecular mechanism of DHI in a collagenase-induced ICH model in aged rats. DHI administration after ICH could significantly improve body weight and neurological deficits, and reduce the hematoma volume and brain water content when compared to the vehicle control. Furthermore, the protective effect of DHI administration o...

Authors: Zhang H, Xue Z, Yi D, Li X, Tan Y, Li J Abstract The efficacy and safety of non-vitamin K antagonist oral anticoagulants (NOACs) in atrial fibrillation (AF) with coronary or peripheral artery disease (CAD or PAD) remain largely unresolved. We, therefore, conducted a meta-analysis to explore the effect of NOACs compared with warfarin in these populations.We systematically searched the Cochrane Library, PubMed, and Embase databases for randomized controlled trials (RCTs) involving NOACs versus warfarin in AF patients with CAD or PAD. A random-effect model was selected to pool the risk ratios (RRs) and 95% co...

Abstract BACKGROUND: Guidelines outlining the role of surgical embolectomy for acute pulmonary embolism remain consensus based, however recent outcomes have improved compared to traditional experiences. The purpose of this study was to examine contemporary outcomes of patients treated for acute pulmonary embolism on a nationwide scale. METHODS: Patients undergoing systemic thrombolysis, catheter-directed therapy, and surgical embolectomy for acute pulmonary embolism from 2010-2014 in the National Inpatient Sample were included. RESULTS: A total 58,974 patients with acute pulmonary embolism were included....

Conclusions: Despite similar initial changes in variables, we found that low CO, DBP, SV, DO2, SvO2, and high lactate are predictive of death in this animal model. The results of this experimental study suggest that maladaptive responses across a range of cardiovascular parameters that begin early after hemorrhage may be predictive of impending death, particularly in situations where early resuscitative treatment may be delayed.

CONCLUSIONS: Hemodynamic failure is an independent risk factor for subsequent hemorrhage in hemorrhagic moyamoya disease. Direct bypass surgery showed a significant preventive effect in the hemodynamically impaired hemispheres. Thus, hemodynamic failure, as well as previously proposed factors such as choroidal anastomosis, should be considered for the surgical indication in hemorrhagic moyamoya disease.Clinical trial registration no.: C000000166 (umin.ac.jp).

Objectives: Up to 41% of intracerebral hemorrhages (ICH) are considered cryptogenic despite a thorough investigation to determine etiology. Certain over-the-counter supplements may increase proclivity to bleeding, and we hypothesize that specifically vitamin E may have an association with ICH and acutely elevated serum levels of α-tocopherol. Our aim is to report 3 cases of recently admitted patients with hypervitaminosis E and otherwise cryptogenic ICH. Methods: At our institution between January and December 2018, 179 patients were admitted with ICH with 73 imputed to be “cryptogenic” (without clear eti...

The antiplatelet landscape for the secondary prevention of ischemic stroke has changed significantly over the past decade. Poststroke dual antiplatelet regimens are becoming increasingly routine as supported by recent literature and guideline recommendations. Dual antiplatelet therapy after stroke generally consists of aspirin and clopidogrel and is considered in the short term after stroke in select populations including those with mild stroke or transient ischemic attack and in patients with severe intracranial atherosclerosis. When initiating dual antiplatelet therapy, factors that may increase a patient's risk of bleed...
