Survivor gives us a lens into regional systems of care for acute ischemic stroke in North Dakota
I just got back from the North Dakota Mission: Lifeline STEMI and Acute Stroke Conference in Bismark, ND. I had a great time and I learned a lot. I often get asked to speak in various venues about acute STEMI and 12-lead ECG interpretation, but for this conference they wanted me to talk mostly about stroke. That turned out to be a good thing because it forced me to read the 2013 AHA / ASA Guildelines for the Early Management of Patients With Acute Ischemic Stroke to make sure I was asking intelligent questions during the panel discussion (which I moderated) and also giving accurate information for the class I taught about ...

Impact of obstructive sleep apnea on cardiac organ damage in patients with acute ischemic stroke
Background and purpose: Both obstructive sleep apnea (OSA) and cardiac organ damage have a crucial role in acute ischemic stroke. Our aim is to explore the relationship between OSA and cardiac organ damage in acute stroke patients. Methods: A total of 130 consecutive patients with acute ischemic stroke were enrolled. Patients underwent full multichannel 24-h polysomnography for evaluation of OSA and echocardiography to evaluate left ventricle (LV) mass index (LV mass/BSA, LV mass/height2.7), thickness of interventricular septum (IVS) and posterior wall (LVPW), LV ejection fraction and left atrium enlargement. Informat...

Cross-Sectional Survey of Workload and Burnout Among Japanese Physicians Working in Stroke Care: The Nationwide Survey of Acute Stroke Care Capacity for Proper Designation of Comprehensive Stroke Center in Japan (J-ASPECT) Study Original Articles
Conclusions— The primary risk factors for burnout are heavy workload, short sleep duration, relatively little experience, and low mental quality of life. Prospective research is required to confirm these findings and develop programs for preventing burnout.

Persistent headache after first-ever ischemic stroke: clinical characteristics and factors associated with its development
CONCLUSION: Persistent headache attributed to ischemic stroke is not rare and frequently leads to medication overuse. The problem is often neglected because of other serious consequences of stroke but actually, it has a considerable impact on quality of life. It should be a focus of interest in the follow-up of stroke patients.PMID:35978288 | DOI:10.1186/s10194-022-01479-9

Sleep Apnea and Stroke
Publication date: Available online 14 March 2015 Source:Canadian Journal of Cardiology Author(s): Owen D. Lyons , Clodagh M. Ryan Stroke is the second leading cause of death worldwide and often has devastating consequences for affected individuals in terms of chronic disability. Traditional risk factors such as age, male sex, ethnicity, hypertension and atrial fibrillation explain 60-80% of the risk of stroke. Obstructive sleep apnea (OSA) is highly prevalent in the post-stroke population and its emerging role as a potential modifiable risk factor for stroke has been recognised in the most recent American Heart Associati...

Obstructive Sleep Apnea and Stroke: Determining the Mechanisms Behind their Association and Treatment Options
Transl Stroke Res. 2023 Mar 16. doi: 10.1007/s12975-023-01123-x. Online ahead of print.ABSTRACTSleep-disordered breathing (SDB) can be a sequela of stroke caused by vascular injury to vital respiratory centers, cerebral edema, and increased intracranial pressure of space-occupying lesions. Likewise, obstructive sleep apnea (OSA) contributes to increased stroke risk through local mechanisms such as impaired ischemic cerebrovascular response and systemic effects such as promoting atherosclerosis, hypercoagulability, cardiac arrhythmias, vascular-endothelial dysfunction, and metabolic syndrome. The impact of OSA on stroke out...

Participation by patients from low- and middle-income countries (LMICs) in trial evidence supporting secondary stroke prevention guideline recommendations
CONCLUSIONS: Compared to their global burden of stroke, LMICs are underrepresented in key clinical trials used in formulating a prominent global stroke prevention guideline. While current therapeutic recommendations are likely applicable to practice settings throughout the world, greater involvement of patients from LMIC settings will enhance the contextual relevance and generalizability of recommendations to these disparate populations.PMID:37028264 | DOI:10.1016/j.jns.2023.120641

Abstract 204: Cross-sectional Survey of Quality of Life and Workload Among Japanese Physicians Working in Stroke Care: The Nationwide Survey of Acute Stroke Care Capacity for Proper Designation of Comprehensive Stroke Center in Japan (J-ASPECT) Study Session Title: Poster Session II
Conclusion: Mental QOL scores of stroke physicians are significantly lower than those of the population norm. Work hours, salary, and numbers of days off are associated with the mental QOL score.

Stroke Risk in Atrial Fibrillation: Beyond the CHA 2 DS 2 -VASc Score
AbstractPurpose of ReviewStroke prevention is the cornerstone of atrial fibrillation (AF) management and the anticoagulation decision is currently based on CHA2DS2-VASc risk score. We discuss several novel risk factors besides those included in CHA2DS2-VASc score and alternative models for stroke prediction.Recent FindingsSeveral clinical markers including obstructive sleep apnea and renal failure, laboratory markers like brain natriuretic peptide, imaging criteria including left atrial appendage morphology, spontaneous echo contrast, and coronary artery calcium score may predict stroke in AF patients. Addition of African ...

Obstructive sleep apnea and risk of stroke: A meta-analysis of prospective studies
Stroke is the second leading cause of death worldwide . 78% of strokes are first attacks , and about 780,000 Americans experience a new or recurrent stroke each year, on average, one stroke every 40s . Any possible means to prevent stroke should, therefore, be a key public health priority. Obesity is one of the leading risk factors for stroke and a target for stroke prevention .

Meta-Analysis of the Association Between Atrial Fibrillation, Hypertension, Sleep-Disordered Breathing, and Wake-Up Stroke
CONCLUSION: This study revealed that atrial fibrillation is an independent risk factor for wake-up stroke and that patients with atrial fibrillation who also experience sleep-disordered breathing tend to have fewer wake-up strokes.PMID:37199028 | DOI:10.14503/THIJ-21-7698

Time to Wake-Up: Extending the Window for Management of Unknown-Onset Strokes
The term “Wake-Up Stroke” is applied to a patient who displays no symptoms before sleep, but wakes with neurologic deficits suggestive of stroke. The current guidelines for acute ischemic stroke limit intravenous tissue plasminogen activator use to stroke patients in whom symptom onset or last known well is less than 4.5 hours. Approximately one-third of acute ischemic stroke patients present with unknown time of symptom onset and are often not eligible for intravenous reperfusion therapy in clinical practice. This review provides an overview of several earlier trials that used advanced neuroimaging to determine eligib...

Effect of Obstructive Sleep Apnea on Frequency of Stroke in Patients with Atrial Fibrillation
Obstructive sleep apnea (OSA) is an independent risk factor for ischemic stroke that is not included in the usual cardioembolic risk assessments for patients with atrial fibrillation (AF). The aim of this study was to investigate the impact of OSA on stroke rate in patients with AF. Patients with AF and new diagnosis of OSA were identified from retrospective chart review. Those with a history of stroke at the time of the sleep study were excluded. The primary outcome was the incidence of stroke, determined by a physician investigator blinded to the results of polysomnography.
