NCT ID: NCT03329365 Not yet recruiting - Clinical trials for Transient Ischemic Attack

Paroxysmal Nocturnal Hemoglobinuria in ESUS & ETUS

Start date: January 2018
Phase: N/A
Study type: Observational

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare acquired clonal hematological disorder, which can cause arterial or venous thrombosis. The frequency of PNH in young patients (< 50 years old) with embolic stroke (ESUS), transient ischemic attack (ETUS) or superior sagittal sinus cerebral venous thrombosis (SSS-CVTUS) of undetermined source, is currently unknown. This study proposes to recruit ESUS, ETUS, SSS-CVTUS patients to determine the frequency of PNH diagnosis confirmed by flow cytometry in these patient populations.

NCT ID: NCT03185520 Recruiting - Clinical trials for Embolic Stroke of Undetermined Source

Young ESUS Patient Registry

Start date: February 15, 2017
Phase: N/A
Study type: Observational [Patient Registry]

This study seeks to determine the clinical characteristics of young ESUS patients using diagnostic criteria of the Cryptogenic Stroke / ESUS International Working Group, and to determine the rates of stroke recurrence, death, and hospital readmission in a contemporary cohort of young ESUS patients during follow-up of up to 18 months.

NCT ID: NCT03107637 Recruiting - Ischemic Stroke Clinical Trials

Transesophageal Echocardiography in Embolic Stroke of Undetermined Source

Start date: October 2016
Phase: N/A
Study type: Observational

The ESUS concept was introduced recently to describe a non-lacunar stroke of undetermined etiology. The following etiological workup is required in this setting: head CT or MRI, 12-lead ECG, transthoracic echocardiography, continuous cardiac monitoring for at least 24 hours after stroke, vascular imaging (ultrasound, magnetic resonance angiography, CT angiography, catheter angiography). Transesophageal echocardiography (TEE) is considered not to be required. However, aortic arch atheroma as diagnosed by TEE in the setting of recent ischemic stroke is a major aortic source of embolism, as supported by numerous well conducted studies. The European Association of Echocardiography considers that TEE is the gold standard for the diagnosis and the characterization of aortic atheroma. It is also the method of choice for the diagnosis of infectious endocarditis. The aim of this work was to evaluate the rate of patients with a therapeutic modification induced by TEE (mainly anticoagulation and surgery), in consecutive patients admitted with ESUS at our institution stroke unit.

NCT ID: NCT02766205 Enrolling by invitation - Clinical trials for Embolic Stroke of Undetermined Source

Prediction of AF in ESUS

Start date: June 2016
Phase: N/A
Study type: Observational [Patient Registry]

The aim of the proposed study is to identify predictors of covert atrial fibrillation (AF) in Embolic Stroke of Undetermined Source (ESUS) patients and develop a prognostic score for the identification of covert AF in this population.
