Deans' stroke musings: Serious Adverse Events and Their Impact on Functional Outcome in Acute Ischemic Stroke in the WAKE-UP Trial

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.

Serious Adverse Events and Their Impact on Functional Outcome in Acute Ischemic Stroke in the WAKE-UP Trial

So you described a problem but did nothing to solve it. In the business world that would be cause for immediate termination.

Abstract

Background and Purpose:

During the first days and weeks after an acute ischemic stroke, patients are prone to complications that can influence further treatment, recovery, and functional outcome. In clinical trials, severe complications are recorded as serious adverse events (SAE). We analyzed the effect of SAE on functional outcome and predictors of SAE in the randomized controlled WAKE-UP trial (Efficacy and Safety of MRI-Based Thrombolysis in Wake-Up Stroke).

Methods:

We performed a post hoc analysis of WAKE-UP, a multicenter, randomized, placebo-controlled clinical trial of magnetic resonance imaging-guided intravenous thrombolysis with alteplase in patients with acute ischemic stroke and unknown time of onset. Functional outcome was assessed by the modified Rankin Scale 90 days after the stroke. SAE were reported to a central safety desk and recorded and categorized by organ system using Medical Dictionary for Regulatory Activities terminology. We used logistic regression analysis to determine the effect of SAE on functional outcome and linear multiple regression analysis to identify baseline predictors of SAE.

Results:

Among 503 patients randomized, 199 SAE were reported for n=110 (22%) patients. Of those patients who did suffer a SAE, 20 (10%) had a fatal outcome. Patients suffering from at least one SAE had a lower odds of reaching a favorable outcome (modified Rankin Scale score of 0–1) at 90 days (adjusted odds ratio, 0.36 [95% CI, 0.21–0.61], P<0.001). Higher age (P=0.04) and male sex (P=0.01) were predictors for the occurrence of SAE.

Conclusions:

SAEs were observed in about one in 5 patients, were more frequent in elderly and male patients and were associated with worse functional outcome. These results may help to assess the risk of SAE in future stroke trials and create awareness for severe complications after stroke in clinical practice.
