Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Poor collateral flow with severe hypoperfusion explains worse outcome in acute stroke patients with atrial fibrillation

So you described a problem but DID NOTHING to solve it. Useless. 

Poor collateral flow with severe hypoperfusion explains worse outcome in acute stroke patients with atrial fibrillation

Abstract

Background: 
 
Atrial Fibrillation (AF) is associated with poorer functional outcomes in acute stroke patients. It has been hypothesized that this is due to poor collateral recruitment.
Aims: This study aimed to investigate the relationship between AF and collaterals with outcome in thrombectomy patients.
 
Methods: 
 
This retrospective cohort study identified 1036 acute ischemic patients from the INternational Stroke Perfusion Imaging REgistry. The cohort was divided into two groups: 432 with AF and 604 without AF. Patients were stratified by collateral grades as good, moderate, and poor. Within each collateral grade, the prediction of AF vs. No AF for good outcome (3-month modified Rankin Scale of 0-2) was determined. Then, within each collateral grade, perfusion was compared between those with and AF and without AF.
 
Results: 
 
AF was negatively associated with good outcome in patients with poor collaterals (26.7% vs. 51.2% for AF vs. No AF, odds ratio=0.32 [95% CI 0.22, 0.50], p<0.001), but not in patients with good (50.9% vs 58.1% for AF vs. No AF, odds ratio=0.75 [0.46, 1.23], p=0.249) or moderate collaterals (43.6% vs 50.9% for AF vs. No AF, odds ratio=0.75 [0.47, 1.18], p=0.214). AF was associated with severe hypoperfusion only in patients with poor collateral flow (54.0 vs. 35.5 ml for AF vs. No AF, p<0.001).
 
Conclusions: 
AF-related stroke is associated with more severe hypoperfusion and worse outcome in those with poor collaterals.
