Bioinformatic analysis for potential biological processes and key targets of heart failure-related stroke
This study aimed to uncover underlying mechanisms and promising intervention targets of heart failure (HF)-related stroke. HF-related dataset GSE42955 and stroke-related dataset GSE58294 were obtained from the Gene Expression Omnibus (GEO) database. Weighted gene co-expression network analysis (WGCNA) was conducted to identify key modules and hub genes. Gene Ontology (GO) and pathway enrichment analyses were performed on genes in the key modules. Genes in HF- and stroke-related key modules were intersected to obtain common genes for HF-related stroke, which were further intersected with hub genes of stroke-related key modu...

Incidence and predictors of stroke during the index event in an ethnically diverse Takotsubo cardiomyopathy population.
Authors: Dias A, Franco E, Janzer S, Koshkelashvili N, Bhalla V, Rubio M, Amanullah S, Hebert K, Figueredo VM Abstract Takotsubo cardiomyopathy (TTS) is a peculiar clinical condition often affecting postmenopausal women after a stressful trigger. The underlying mechanisms have not been completely elucidated but several hypotheses have been advanced, with catecholamine cardiotoxicity, microvascular dysfunction and coronary artery spasm each suggested to play a role. The incidence of stroke after TTS appears to range from 0% to 7.7%, and interestingly TTS has been described as both a cause and a complication of strok...

Noninfectious complications of acute stroke and their impact on hospital mortality in patients admitted to a stroke unit in Warsaw from 1995 to 2015
Conclusions Over the last two decades Polish urban stroke units may have achieved a significant reduction of the occurrence of some noninfectious complications (i.e. MI, exacerbated CHF and DVT). However, the list of conditions associated with stroke unit mortality includes not only MI and exacerbated CHF but also PE, gastrointestinal bleeding and recurrent stroke.

Molecular imaging of inflammation in the brain-heart axis after ischemic stroke: comparison of two murine stroke models.
Conclusions: In contrast to topical ET-1 application after craniotomy, the intravascular MCAo model enables imaging studies of brain-heart networking after stroke, which evokes elevated TSPO PET signal in both brain and heart. The severity of cerebral ischemic damage may contribute to cardiac dysfunction via systemic inflammatory networking.

Predicting Adverse Events beyond Stroke and Bleeding with the ABC-Stroke and ABC-Bleeding Scores in Patients with Atrial Fibrillation: The Murcia AF Project.
CONCLUSION:  In AF patients, the ABC-stroke and ABC-bleeding scores demonstrated similar predictive ability for outcomes beyond stroke and bleeding, including MI, acute HF, a composite of cardiovascular events, and all-cause deaths. This is consistent with nonspecificity of biomarkers that predict "sick" patients or poor prognosis overall. PMID: 32506417 [PubMed - as supplied by publisher]

Outcome Predictors of Stroke Mortality in the Neurocritical Care Unit
Conclusions: Our analysis showed that mortality risk in critically ill patients with hemorrhagic stroke was closer to mortality risk in patients with ischemic stroke than has been reported in other analyses. Hypertension, chronic heart failure, ischemic heart disease and atrial fibrillation were the most frequent comorbidities in patients who developed severe (life-threatening) stroke. Coma and cerebral edema on admission appear to be associated with poor outcome. This is the first publication of in-hospital stroke mortality from a Central Asian population and could form the basis for future research including development ...
