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.

Background: Intravenous thrombolysis and endovascular thrombectomy have been approved for acute ischemic stroke (AIS). However, only a minority of patients received these treatments in China. We aimed to evaluate the efficacy and safety of tirofiban in patients with AIS who were not undergoing early recanalization treatments.

Methods: Patients with mild-to-moderate stroke [National Institutes of Health Stroke Scale (NIHSS) score, 4–15] were enrolled in this study. Patients due to cardiogenic embolism were excluded. Eligible patients within 12 h from symptom onset were randomly assigned (1:1) to receive tirofiban (a loading dose of 0.4 μg/kg/min over 30 min and a maintenance dose of 0.1 μg/kg/min up to 48 h) followed by regular treatment or to receive regular treatment (aspirin at a dose of 100 mg per day for 90 days) (control). The primary outcome was the proportion of favorable functional outcomes at 90 days [defined as the modified Rankin Scale (mRS) score of 0–2]. The secondary outcomes included a shift in the distribution of the mRS scores at 90 days and the NIHSS score at 24 h and 7 days. The primary safety outcome was symptomatic intracranial hemorrhage (sICH) within 7 days after tirofiban treatment.

Results: A total of 380 eligible patients were randomly assigned to the tirofiban group (n = 190) or the control group (n = 190). The proportion of favorable functional outcomes was higher in the tirofiban group (79.1%) than that in the control group (67.8%) at 90 days [odds ratio (OR), 1.80; 95% CI, 1.12–2.90; p = 0.0155]. An improvement was also observed in the overall distribution of the 90-day mRS scores (adjusted common OR, 2.31; 95% CI, 1.58–3.39; p < 0.0001). Additionally, the median NIHSS score was lower in the tirofiban group than in the control group at 7 days (3 vs. 5, p < 0.0001). Next, we observed that the occurrence of sICH did not differ between the two groups.

Conclusion: Our trial supports that tirofiban was safe and effective and might be a remedial treatment for patients with AIS who did not receive recanalization treatments.

Introduction

Acute ischemic stroke (AIS) is commonly characterized by high disability and mortality rates, and it has become the leading cause of death in China (1). For AIS treatment, extraordinary progresses including intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) and endovascular thrombectomy (EVT) have been made (24). However, the narrow time window is a huge challenge. It was reported that only 10–20% of patients with AIS could reach the hospital within 3 h in China (1). Other factors including hemorrhagic transformation, contraindications, and high healthcare costs, also limit the application rate of rt-PA and EVT. China Stroke Statistics 2019 reported that about 24% of eligible patients (<3% of all the patients) received rt-PA and 28.1% received EVT, which was much less than that in high-income countries (5, 6). Given the current situation, it is urgent to explore other remedial actions for patients with AIS.

More evidence suggest that the administration of antiplatelets is necessary for AIS treatment (7, 8). The Clopidogrel in High-Risk Patients with Acute Nondisabling Cerebrovascular Events (CHANCE) trial has demonstrated that dual-antiplatelet therapy combination clopidogrel with aspirin could reduce the early risk of stroke for transient ischemic attack and minor ischemic stroke (9). Moreover, the Acute Stroke or Transient Ischaemic Attack Treated with Ticagrelor and ASA [acetylsalicylic acid] for Prevention of Stroke and Death (THALES) trial also observed similar results by combining ticagrelor and aspirin (10). However, the current antiplatelet treatment cannot completely block all signaling pathways involved in platelet aggregation, leading to a potential possibility of new thrombosis after AIS (11).

Tirofiban is a fast-acting glycoprotein (GP) IIb-IIIa inhibitor with short half-life and could inhibit the final common pathway to platelet aggregation by reversibly blocking fibrin binding receptors (12). It has been approved for the treatment of myocardial revascularization (13). Several clinical trials on tirofiban have also been conducted in AIS. However, most of the data comes from the trials of tirofiban treatment in combination with rt-PA or EVT (1417). These trials indicated that tirofiban in combination with rt-PA or EVT was associated with favorable functional outcomes at 3 months, and not associated with a higher rate of symptomatic intracranial hemorrhage (sICH). These findings suggest that the sequential application of tirofiban could improve the prognosis of stroke. Based on the previous clinical studies, we believe that tirofiban could be a promising drug for patients with AIS. However, no clinical trials are evaluating the use of tirofiban in patients who were not undergoing rt-PA or EVT therapy at the early stage.

The Efficacy and Safety of Tirofiban in Clinical Patients with acute Ischemic Stroke (ESCAPIST) trial was conducted to test the hypothesis that tirofiban with regular treatment would improve functional outcome, and would not increase the risk of sICH in patients with AIS within 12 h after symptom onset.
