Natural History of Stroke: Cause and Development Clinical Trials Resources presented on Clinical Trials Search is not meant to be a substitute for proven health advice, calls or treatment with a real medical. We aren't mDs. Always consult your doctor on Natural History of Stroke: Cause and Development conditions. Clinical Trials Search.org is a website dedicated to listing clinical research studies in human subjects. Natural History of Stroke: Cause and Development Clinical research trials and Natural History of Stroke: Cause and Development healthcare trials take place in a lot of of localities throughout the U.S.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials typically assess the effectiveness of new does drugs. The function of the studies / projects is to figure out specific human medical questions. Clinical trials are a popular means for doctors, government agencies, and private sector corporations to find cures for all varieties of conditions, like Natural History of Stroke: Cause and Development. Natural History of Stroke: Cause and Development Clinical Trials and other clinical trials allow volunteers to access health treatment options before they are available to the masses. Many times the subjects receive professional assistance for free, and every now and again they are compensated for their time. Sometimes there is a cost for a Natural History of Stroke: Cause and Development clinical trial. Human subjects often obtain the finest healthcare possible for their Natural History of Stroke: Cause and Development condition. Hazards are a reality, nevertheless, and might include additional or frequent dr. calls, health hazards (potentially life-jeopardizing), and/or the treatment being uneffective. Trials are federally regulated with stern guidelines to protect clinical trials patients.

Natural History of Stroke: Cause and Development
For Condition: Cerebrovascular Accident,Transient Ischemic Attack
Status: Recruiting
Sponsor(s): National Institute of Neurological Disorders and Stroke (NINDS) ,
Synopsis: The purpose of this study is to learn more about stroke and obtain information that may serve as the basis for future investigations. It will 1) establish a registry of patients with cerebrovascular disease (stroke); 2) characterize the natural history of acute stroke and transient ischemic attacks (TIA)-an interruption of blood flow to the brain that causes stroke symptoms for a short period of time); and 3) evaluate the data to generate ideas for future studies. Patients 18 years of age or older with suspected acute stroke or TIA may be eligible for this study. Subjects will be recruited from patients who present with stroke at the emergency department of Suburban Hospital in Bethesda, Maryland. The study will gather data collected from diagnostic and laboratory tests the patient undergoes as part of standard medical care, including findings of medical and neurological examinations and other tests. In addition, studies will be done for research purposes only to gather data about stroke and TIA. These may include the following: - Blood and urine tests-not more than 2 tablespoons of blood will be drawn for various tests. - Electrocardiogram (EKG) (heart tracing)-electrodes placed on the chest wall detect the heartbeat and heart rhythm. - Computed tomography (CT) scan of the head-specialized X-rays are used to obtain images of the brain. - Magnetic resonance imaging (MRI) of the brain-a strong magnetic field and radio waves are used to produce images that provide information about the brain tissue and blood vessels. - Transcranial Doppler (TCD)-sound waves are used to image the arteries of the brain and neck. - Echocardiogram-sound waves are used to image the heart and evaluate heart function. Patients may be asked to return to Suburban Hospital for follow-up testing in 1, 3, and/or 12 months, when some of these tests may be repeated to assess changes over time
Details: OBJECTIVE: This is a natural history/disease pathogenesis protocol for evaluation of patients with suspected acute stroke or transient ischemic attack (TIA). The purpose of this protocol is to generate natural history data to serve as the basis for future hypothesis-driven protocols as well as to contribute to the clinical and physiological understanding of cerebrovascular disease through the description of disease manifestations and the relationship among clinical, hematologic, and radiologic variables. STUDY POPULATIONS: Patients will be recruited from the collaborative stroke program between NINDS and Suburban Hospital and will be followed for the duration of their hospitalization. Select patients will then be seen for follow-up at 1, 3, and/or 12 months. DESIGN: Clinical issues to be addressed will include disease manifestations, natural history, acute disease management, and psychological/behavioral impact of the disease. Because of the nature of acute cerebrovascular disease, it is important to note that the research performed under this protocol will not interfere with emergency clinical evaluation or treatment of patients, as specified in the clinical care pathway in place for the standard care of stroke patients at Suburban Hospital. Due to the emergency nature of clinical evaluation and therapy for stroke patients, waiver of written informed consent in certain circumstances for minimal risk procedures (e.g., collecting extra tubes of blood during initial phlebotomy for emergency room blood tests) will be required when it is impossible to obtain consent prior to critical emergency treatment procedures that may change the values of the variables. Patients will not be treated with experimental therapies as part of this protocol. OUTCOME MEASURES: In addition to clinical, imaging and laboratory data that are part of routine clinical care of the patient, a variety of outcomes will be collected, e.g., infarct volume, clinical outcomes on NIH Stroke Scale, modified Rankin Score, Barthel Index, blood marker of inflammation and coagulation. Statistical analysis plans will be developed as specific questions and hypotheses are generated.
Eligibility:
Study Type: Observational, Natural History
Minimum Age/Maximum Age: /
Genders: Both
Protocol Entry Criteria: INCLUSION CRITERIA: Patients will be recruited for enrollment in this protocol during the acute (less than 48 hours) phase of disease from the Stroke Program at the participating hospital. EXCLUSION CRITERIA: Patients is less than 18 years of age. Patients with contraindication to MRI scanning will be excluded from any testing which involves the use of MRI. These contraindications include patients with the following devices or conditions: a) Central nervous system aneurysm clips; b) Implanted neural stimulator; c) Implanted cardiac pacemaker or defibrillator; d) Cochlear implant; e) Ocular foreign body (e.g. metal shavings); f) Insulin pump; g) Metal shrapnel or bullet; h) Any implanted device that is incompatible with MRI. Patients with a condition which precludes entry into the scanner (e.g. morbid obesity, claustrophobia, etc.) will not be included in the MRI portion of this study. Pregnant or lactating women will be excluded from studies involving the administration of contrast agents. Pregnant women will be excluded from CT scans specific to this protocol.
