The Relationships Among Regionalization, Processes, and Outcomes for Stroke Care: A Nationwide Population-based Study
We examined the association of regionalization with processes and outcomes, and the mediating effect of processes of care on the association between regionalization and mortality for acute stroke in Taiwan. We analyzed all 229,568 admissions with acute ischemic stroke from January 2004 to September 2012 through Taiwan's National Health Insurance Research Database. Regionalized care for acute stroke has been implemented since July 2009 in Taiwan. Rates of thrombolytic therapy within 3 hours after onset of ischemic stroke, average numbers of processes of care, and 30-day mortality rates at monthly intervals for baseline...

Similar thrombolysis outcomes in acute stroke patients with and without atrial fibrillation if pre-stroke CHA2DS2-VASc score is low: A retrospective study
The prognosis of acute ischemic stroke patients treated with intravenous (IV) recombinant tissue plasminogen activator (rtPA) is poorer in patients with atrial fibrillation (AF) than patients without AF, which might be related to the greater stroke severity in AF patients. Higher pre-stroke CHA2DS2-VASc scores are associated with greater stroke severity and poorer outcomes. AF Patients tend to have higher CHA2DS2-VASc scores than the non-AF patients. We thus hypothesized that pre-stroke CHA2DS2-VASc scores can be used to improve outcome stratification of IV thrombolysis therapy in acute stroke patients with and without AF....

Statin Withdrawal Beyond Acute Phase Affected Outcome of Thrombolytic Stroke Patients: An Observational Retrospective Study
Abstract: Statin withdrawal is associated with deleterious outcome on stroke patients. Whether risk changes over time, depends on concomitant treatment of intravenous thrombolysis, or both remains to be clarified. We assessed the influence of statin withdrawal within 3 weeks while initiated in acute phase (72 hours) among patients receiving intravenous thrombolysis. This was a monocentered retrospective observational study enrolling intravenous thrombolytic stroke patients from June 2009 to May 2014. Consecutive patients were distinguished into 3 groups according to the initiation and withdrawal of statin: the reference gr...

Impact of atrial fibrillation on in-hospital mortality of ischemic stroke patients and identification of promoting factors of atrial thrombi – Results from the German nationwide inpatient sample and a single-center retrospective cohort
Ischemic stroke is one of the leading causes of death and disability. Atrial fibrillation (AF) is a well-recognized risk factor for ischemic stroke. We aimed to investigate the impact of AF on in-hospital mortality of ischemic stroke patients and to identify parameters associated with intra-cardiac thrombogenic material. Patients were selected by screening the nationwide sample for ischemic stroke by ICD-Code (I63), stratified for AF. In this cohort, the association between in-hospital deaths and AF was investigated. In a second study, we performed a retrospective analysis of patients who underwent transesophageal echoc...

d-dimer and diffusion-weighted imaging pattern as two diagnostic indicators for cancer-related stroke: A case–control study based on the STROBE guidelines
The aim of this study was to evaluate the risk factors and elucidate the clinical characteristics of cancer-associated ischemic stroke to differentiate it from conventional ischemic stroke in China and East Asia. Between June 2012 and June 2016, a retrospective analysis was performed on 609 stroke patients with cancer. They were divided into 3 groups: cancer-stroke group (CSG, 203 cases), stroke group (SG, 203 cases), and cancer group (CG, 203 cases). The d-dimer levels and diffusion-weighted imaging lesion (DWI) pattern were compared to an age- and sex-matched control group. The most common cancer types were colorectal ca...

Renal Dysfunction and Thrombolytic Therapy in Patients With Acute Ischemic Stroke: A Systematic Review and Meta-Analysis
This study aimed to evaluate the safety and effectiveness of thrombolytic therapy in acute stroke patients with renal dysfunction using a meta-analysis. We systematically searched PubMed and EMBASE for studies that evaluated the relationship between renal dysfunction and intravenous tissue plasminogen activator (tPA) in patients with acute ischemic stroke. Poor outcome (modified Rankin Scale ≥2), mortality, and symptomatic intracranial hemorrhage (ICH) and any ICH were analyzed. Fourteen studies were included (N = 53,553 patients). The mean age ranged from 66 to 75 years. The proportion of male participants was 49% t...

A case report of left atrial myxoma-induced acute myocardial infarction and successive stroke
Rationale: Left atrial myxoma is a common primary cardiac tumor, however, due to poor image quality or atypical myxoma images, it is often misdiagnosed by echocardiograph. A case of left atrial myxoma being misdiagnosed as a thrombus, which successively caused acute myocardial infarction (AMI) and stroke, is very rare. Contrast-enhanced echocardiography can play an important role in definitive diagnosis. Patient concerns: A 44-year-old woman was diagnosed AMI because of chest pain with no significant stenosis in the coronary arteries. One month later, the patient was suddenly found unconscious, magnetic resonance imag...
