Center for Stroke Research Berlin (CSB) Prospective Stroke Cohort

Stroke

The primary aim of the study is to derive and validate risk scores for vascular endpoints (recurrent stroke, myocardial infarction, and other complications of stroke) and for death following an incident stroke. For this purpose patients with an incident stroke will be followed for 36 months with additional assessments at 12, 24 and 36 months.

Atrial Tachycardia as a Predictor of Atrial Fibrillation, Stroke and Mortality in Cryptogenic Stroke...

Cryptogenic StrokeAtrial Fibrillation1 more

There is few information about the association between supraventricular arrhythmia different from atrial fibrillation (AF) or atrial Flutter and the risk of stroke. In this study the investigators hypothesized that the presence of atrial tachycardia would lead to atrial fibrillation and recurrent stroke in patients hospitalized for cryptogenic stroke. The investigators study the association of atrial tachycardia (AT), defined as four or more consecutive premature atrial beats, and AF, recurrent stroke and cardiovascular mortality in 192 consecutive patients hospitalized because of cryptogenic stroke. The follow-up was 12 months for all population

A Pharmacogenomics Study of Safety and Efficacy of Enalapril or Enalapril-Folic Acid Therapy in...

Enalapril Adverse ReactionPharmacogenomics1 more

Dry cough is the most common adverse reaction of angiotensin converting enzyme, including enalapril, in Chinese population. Clinical observations suggest that the incidence of ACEI-induced dry cough is different between Chinese and other racial groups, however, there is still lack of research data in Chinese. Stroke is the second leading cause of death in the world and leading cause of death in China. Except the known risk factor such as hypertension, high homocysteine level, folic acid deficiency, the impact of genetics should not be ignored. In this study, we will investigate whether there are specific genotypes which may predict the incidence of (1)enalapril-induced dry cough in Chinese and (2)first stroke in hypertensive patients taking enalapril or enalapril-folic acid therapy, so as to provide a basis for developing guidelines on precision medication in enalapril therapy apply to Chinese population.

Prediction of AF in ESUS

Embolic Stroke of Undetermined Source

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.

The Findings of Ultrasound Elastography and ARFI in Strokes Patients With Spastic Elbow Flexor

Cerebrovascular Accident

The aim of this study: 1. To evaluate the correlation between the clinic tools and ultrasound elastography/ ARFI imaging in stroke patients. 2. To assess the reliability of elastography/ ARFI imaging in spasticity evaluation of stroke patients.

Electrical Impedance Tomography of Stroke and Brain Injury

StrokeCraniocerebral Injuries

The purpose of this study is to determine if Electrical Impedance Tomography (EIT) can produce reproducible and accurate images in people with stroke or head injury compared to existing standards such as MRI, CT. Electrical Impedance Tomography is a relatively new medical imaging method, which has the potential to provide novel images of brain function. It is fast, portable, safe and inexpensive, but currently has a relatively poor spatial resolution. It produces images of the internal electrical impedance of a subject with stroke or head injury using rings of ECG like electrodes on the skin. EIT recording will take place as early as possible, usually within 24 hours of admission. Following completion of the recording, the EIT images will subsequently be analysed and compared to other imaging data for accuracy.

Norwegian Microemboli in Acute Stroke Study

Ischemic StrokeEmbolic Stroke1 more

BACKGROUND: The cause of ischemic stroke remains undetermined in 30-40% of the cases, but circulating blood clots (thromboemboli) are a postulated common denominator in approx. 75% of patients. Transcranial Doppler monitoring (TCDM) is a non-invasive method of detecting circulating microemboli (CME) in the human cerebral circulation. The method is not used systematically in unselected groups of patients with repeated long-term registrations. New ultrasound equipment is ambulatory, less unpleasant for the patient and allows extended monitoring sessions. This may vastly simplify the implementation of TCDM as a clinically useful diagnostic tool. AIMS: Determine the usefulness of TCDM in acute stroke diagnostics by assessing prevalence and frequency of CME in unselected patients with ischemic stroke, the influence of antithrombotic drugs on CME and the relationship between MES and recurrent stroke or transient ischemic attack (TIA). HYPOTHESES: Prevalence and frequency of CME are higher during the first 24 hours than at later follow-up. Stroke etiology can be assessed by the presence or absence of CME. Presence of CME is associated with increased risk of recurrent TIA of stroke within 3 months and 1 year. Cessation of CME after the start of antithrombotic treatment is associated with reduced risk of recurrent TIA or stroke.

Assessment and Quantification of Collateral by ASL MRI

Stroke

Collateral circulation supports brain tissues to maintain blood perfusion in cerebral ischemic stroke and are of great benefit for a better outcome. A non-invasive approach relative to currently widely used digital subtraction angiography (DSA) is needed. ASL (arterial spin labeling) is a novel perfusion method without contrast agent injection and features both temporal and cerebral blood flow(CBF) information. The investigators applied multiple post labeled delay(PLD) time to pseudo-continuous Arterial Spin Labeling (3D pCASL) MRI and subtraction images were obtained to evaluate the collateral robustness and quantitatively assess the collateral perfusion in patients with unilateral middle cerebral artery atherosclerotic stenosis and the ability to predict future stroke recurrence.

Stroke Prevention and Treatment System in Shanghai: a Network of Public Healthcare of Stroke

Stroke

The Shanghai Stroke Service System(4S) has been established as the network of stroke care in greater Shanghai metropolitan area. The system includes 11 territorial-care hospitals and their comprehensive stroke unites that provide 24h/7day acute stroke care to a population of 40 million in Shanghai. The System comprised of two consecutive phases, the acute phase that emphasized on providing thrombolysis, and the in-hospital phase that concentrated on the effort of recovery and secondary stroke prevention. The novel electronic data aquisition system provides the contiguous data of clinical care of stroke patients from the acute phase of management to inpatient rehabilitation. This system has been implemented and maintained as an ongoing quality of stroke care project that monitored the process of routine stroke care in Shanghai. It is funded by the Shanghai Municipal Commission of Health and Family Planning. Our analysis of the project was approved by the Ethics Committee, which agreed that no written informed consents were needed since the study only was consisted of a population-based retrospective data analysis.

Comparing the Behavior of the Cardiac Autonomic Regulation System During 24h in Patient Post Stroke...

Stroke

By Investigating the heart rate variability (HRV) of 15 patients after stroke and compare it to the HRV of 15 orthopedic patients, the investigators hope to achieve 3 main goals: 1. To describe the 24-hour circadian rhythm of heart rate among patients after stroke in the sub-acute phase during 3 days. 2. To examine the differences in the circadian rhythm of heart rate along 3 days between patients after stroke in the sub-acute phase and control group matched by age and gender. 3. To describe the reaction and examine the differences in reactions of the heart autonomic system during rest, paced breathing and activity in both groups- stoke and control. The HRV will be monitored by Polar watch and the activity will be measured by accelerometer, both will be attached to the patients at the beginning of the trial and will stay on them for 3 whole days.
