We previously reported that thrombosis-inducing activity (TIA) is present in plasma from patients with advanced lung cancer. Of 73 patients with non-small cell lung cancer, stages IIIb and IV, 41 (56 percent) had such activity in plasma. The median survival time was significantly shorter in the TIA-positive vs the TIA-negative group. When 34 of those 73 patients who had died at Kyushu Universit...

Objective The purpose of this study was to identify the predictors of subsequent ischemic stroke events in patients with transient ischemic attack (TIA) attributable to intracranial arterial occlusive lesions. Methods The study population included 82 patients (55 men; mean age, 69.3±12.1 years) with TIA caused by intracranial arterial occlusive lesions who were admitted to our stroke care unit ...

OBJECTIVE This study had been designed to find the relative frequency of each of ischemic stroke`s risk factors and to evaluate the action of the first contact physician for transient ischemic attack (TIA) cases. METHODS This study is a cross sectional study that enrolled 100 randomly selected patients with clinical and radiological diagnosis of ischemic stroke, who had attended Al-Yarmouk Te...

Reduced impact of ischemia after an initial ischemic insult—ischemic preconditioning—has been demonstrated in a number of animal models. Transient ischemic attack (TIA) may produce ischemic preconditioning in people who have a subsequent stroke within days of an initial ischemic insult. We performed a cohort study of all 1707 patients given a diagnosis of TIA by an emergency department physicia...

BACKGROUND AND PURPOSE Population-based data on transient ischemic attack (TIA) incidence are scarce. This study defines incidence rates of first-ever TIA in Novosibirsk, Russia, during 1987-1997 and compares the incidence of first TIA with that of first stroke. METHODS This is a prospective registry population-based study of all new cases of TIA and stroke in an overall population of 455 765...

BACKGROUND AND PURPOSE The commonly quoted early risks of stroke after a first transient ischemic attack (TIA)-1% to 2% at 7 days and 2% to 4% at 1 month-are likely to be underestimates because of the delay before inclusion into previous studies and the exclusion of patients who had a stroke during this time. Therefore, it is uncertain how urgently TIA patients should be assessed. We used data ...

Occurrence of transient ischemic attacks (TIA) and cerebral strokes is a recognized risk associated with cocaine abuse. Here, we use a rodent model along with optical imaging to study cocaine-induced TIA and the associated dynamic changes in cerebral blood flow velocity (CBFv) and cerebrovasculature. We show that chronic cocaine exposure in mice resulted in marked cortical hypoperfusion, in sig...
