Study of a novel small molecule, LT3001, in a thromboembolic stroke model in non-human primates

LT3001 is a novel small molecule designed to have thrombolytic and free radical scavenging activities. Its potential safety and efficacy in treating acute ischemic stroke was evaluated using a thromboembolic stroke model in adult Cynomolgus macaque.

CONCLUSIONS: Although statistical significance was not reached, the efficacy of prasugrel was potentially different between stroke subtypes, warranting further studies. PMID: 32493881 [PubMed - as supplied by publisher]

Atrial fibrillation is the most common sustained cardiac arrhythmia in the general population. In western countries with aging populations, atrial fibrillation poses a significant health concern, as it is associated with a high risk of thromboembolism, stroke, congestive heart failure, and myocardial infarction. Thrombi are generated in the left atrial appendage, and subsequent embolism into the cerebral circulation is a major cause of ischemic stroke. Therefore, patients have a lifetime risk of stroke, and those at high risk, defined as a CHA2DS2-VASc2 (congestive heart failure, hypertension, age>75 years, diabetes mel...

We report the results of transcranial ultrasound monitoring in three patients with intracranial arterial stenosis of the middle cerebral artery treated with the only drug-eluting balloon certificated for intracranial use in highly symptomatic intracranial arterial stenosis, ELUTAX "3" (AR Baltic Medical). We performed transcranial Doppler ultrasounds 24 h, 72 h, 10 days, 15 days and 30 days after the angioplasty, thereby measuring mean flow velocity (MFV) in the maximum stenosis area in patients with symptomatic steno-occlusive disease of the middle cerebral artery treated with ELUTAX "3". Two patients ...

AbstractPurpose of reviewIt has become evident that strict time-based criteria are not optimal in selecting patients for acute stroke intervention, leaving the majority of patients untreated due to missing universal time-based criteria. We discuss the pathophysiologic basis for a shift of focus from time to the imaging evidence of salvageable tissue, as well as clinical and imaging tools.Recent findingsThere is strong evidence for the benefit of thrombectomy in patients with a sustained salvageable tissue presenting within 24  h. Although evidence of benefit is limited in patients presenting longer than 24 h, tho...

This cohort study estimates associations between intravenous tissue plasminogen activator (tPA) door-to-needle times of less than 4.5 hours for acute ischemic stroke and 1-year mortality or readmission among Medicare beneficiaries aged 65 years or older.

The role of intravenous thrombolytic therapy in the management of acute ischemic stroke is well established, and faster administration of intravenous tissue plasminogen activator (tPA) has been associated with better short-term outcomes in clinical practice.

AbstractThe cerebrovascular effects of a failing heart-pump are largely unknown. Chronic heart failure (HF) might cause pre-conditioning effect on cerebral hemodynamics but not study so far in acute stroke. We aimed to investigate if HF induces effects in dynamic cerebral autoregulation (CA), within 6  h of symptom-onset through chronic stage of ischemic stroke. We enrolled 50 patients with acute ischemic stroke. Groups with (N = 8) and without HF and 20 heathy controls were compared. Arterial blood pressure (Finometer) and cerebral blood flow velocity (transcranial Doppler) were monitored w ithin 6 and ...

Authors: Poznyak AV, Zhang D, Grechko AV, Wu WK, Orekhov AN Abstract Atherosclerosis is a major cause of disease-related mortality around the globe. The main characteristic of the disease is an accumulation of plaque on the arterial wall and subsequent erosion or rupture of some plaques. Atherosclerosis often leads to cardiovascular disease and such acute complications as myocardial infarction or ischaemic stroke due to thrombus formation. Most recent advances in atherosclerotic research state that the modifications of low- density lipoprotein (LDL) are one of the most significant stages in the disease initiation, ...

Abstract Cardiogenic stroke (CS), characteristic causes of which include atrial fibrillation (AF) and right-to-left shunting due to a patent foramen ovale (PFO), has a well-known tendency to be associated with a more extensive ischemic area. This may result in severe neurological damage, and require strict life-long antithrombotic therapy. However, the fact that some patients have problems complying with the requirement for extended oral antithrombotic treatment has motivated the development of alternative approaches for stroke prevention. Heart structures such as the left atrial appendage (LAA) and PFO are potent...
