BACKGROUND AND PURPOSE Transient ischemic attack (TIA) diagnosis is frequently difficult in clinical practice. Noncerebrovascular symptoms are often misclassified as TIA by nonspecialist physicians. Clinical prediction rules such as ABCD(2) improve the identification of patients with TIA at high risk of early stroke. We hypothesized that the ABCD(2) score may partly improve risk stratification ...

occurred within the first four days after the TIA. Notably, of the patients with TIA who returned to the emergency department with stroke (10.5 percent), approximately one half had the stroke within the first 48 hours after the initial TIA. In 2.6 percent of patients with TIA, hospitalization was required for cardiac events, including congestive heart failure, unstable angina, cardiac arrest, a...

Not only do we advise our patients and offer interventions to control vascular risk factors but we are often the first port of call for patients seeking health care after a transient ischaemic attack (TIA). 1 The neurologist's definition of TIA has recently changed and patients must have had a transient clinical deficit suggesting focal brain or retinal dysfunction with a 'tissue' criterion of ...

Abstract Digital twins are rapidly establishing themselves as a necessary step in digital change also the design of automated and robotic manufacturing systems. The twin serves an interface between physical industrial products worlds. This allows you to map continuous availability data throughout lifecycle from product planning development, production commissioning use recycling. An important t...

Background: As a significant number of patients diagnosed with transient ischemic attack (TIA) at emergency department are at risk to develop TIA or cerebral vascular accident (CVA), several attempts have been made to figure out a predictive method to detect those at higher risk of such attacks. Therefore, the present study was aimed to evaluate the role of ABCD2 scoring including age, blood pr...

BACKGROUND AND PURPOSE Transient ischemic attack (TIA) is a risk factor for stroke. However, TIA may also serve as a preconditioning stimulus, reducing damage from subsequent stroke. We tested the hypothesis that experimental TIA induces expression of P450 2C11, an arachidonic acid epoxygenase that produces vasodilator epoxyeicosatrienoic acids, leading to increased tissue perfusion and reduced...

BACKGROUND AND PURPOSE To evaluate a novel emergency department-based TIA triage system. METHODS We developed an approach to TIA triage and management based on risk assessment using the ABCD(2) score in combination with early cervical and intracranial vessel imaging. It was anticipated that this triage system would avoid hospitalization for the majority of TIA patients and result in a low rat...

BACKGROUND AND PURPOSE MRI is more sensitive than CT, but the significance of brain abnormalities seen on MR images obtained in older subjects with transient ischemic attack (TIA) is not clear. We studied the prevalence and risk factors associated with MRI-demonstrated infarcts in elderly subjects with a history of TIA. METHODS Participants of the Cardiovascular Health Study, aged 65 years or...

We prospectively followed 78 patients with transient ischemic attacks (TIAs) from the carotid artery territory and 45 patients with minor ischemic strokes for 3 years. The mean +/- SD age of the patients in the TIA group was 66.9 +/- 7.9 years compared with 68.8 +/- 6.7 in the minor stroke group. Mortality among the TIA patients was significantly higher than that among minor stroke patients (18...

BACKGROUND Transient nonfocal neurological symptoms may serve as markers of cardiac dysfunction. We assessed whether serum N-terminal pro-brain natriuretic peptide (NT-proBNP) levels, a biomarker of cardiac disease, are increased in patients with transient ischemic attack (TIA) accompanied by nonfocal symptoms and in patients with attacks of nonfocal symptoms (transient neurological attack [TNA...
