简要总结

This is a pragmatic, multi-center, non-interventional, non-randomized prospective observational study.

详细描述

This is a prospective study of patients with acute stroke or transient ischemic attack within 72 hours of symptom onset. It is to mainly observe the patients' prognosis following the prescription of clopidogrel resinate and aspirin, collect relevant data and create big data for stroke. Based on this data, an AI, using various advanced statistical methodologies and deep learning techniques will be developed, and offer information regarding stroke prognosis by extracting markers that are characteristic of the relationship between stroke and the study drug.

These analyses and results will include information on which drug regimen will better prevent the progression or recurrence of stroke by considering individual patient conditions. This is a pragmatic trial based on the prescription and treatment processes of routine clinical practice. Thus, there is no major restriction and with only the minimum exclusion criteria in place, it does not hinder usual clinical practices. Therefore, selecting and changing a patient's antiplatelet agents should be a rational medical judgment made by the patient's attending physician. The study will proceed without any major change in the sequence of routine clinical examinations, prescriptions, treatments, observations, etc. Provided, the process of storing and analyzing relevant information will be added to each study procedure in accordance with study methodologies and conditions no other special efforts or limitations will be required.

The data will be collected prospectively, and the AI will generate brain imaging data and prognostic indicators for 3-months after stroke has occurred. The performance of the AI will be verified with independent test sets.

  • Patients with acute non-cardiac stroke or transient ischemic attack within 72 hours of the onset (in the case of a transient ischemic attack, presence of ischemic/ischemic lesion on DWI or PWI).
  • Patients whose informed consent document within 72 hours of onset was signed and submitted.
  • Patients who were treated with aspirin alone or aspirin plus clopidogrel resinate following stroke.

排除标准

  • Patients who suffered severe stroke (National Institutes of Health Stroke Scale> 16).
  • Patients who received emergency remission therapies such as tPA and thrombolysis.
  • Patients with neurological deterioration prior to signing an informed written consent document.
  • Patients who have undergone patency procedures (surgery or stent insertion) in the cerebrovascular or carotid arteries following stroke or are expected to do so.
  • Patients who are scheduled to undergo major surgery.
  • Patients who developed stroke during procedure/surgery.
  • Patients with recent history (in the past three months) of cerebral hemorrhage.
  • Patients with active internal bleeding.
  • Patients with severe anemia (Hb <10 g / dL) or bleeding tendency (platelet <100,000 / uL or PT-INR> 1.7).
  • When a patient's life expectancy is less than 6 months due to other systemic disease.

结局指标

主要结局

Rate of patients with myocardial infarction under hospital treatment.

时间窗: up to 3 months after stroke onset

The diagnosis of MI will be based on an algorithm developed from the Universal Definition of Myocardial Infarction (Circulation 2007 116:2634-2653) that takes into account 5 categories of clinical information from the acute event: rise and/or fall of cardiac biomarkers, ECG abnormalities, clinical setting, imaging evidence, and pathology.

Rate of patients with major hemorrhage other than intracranial hemorrhage under hospital treatment.

时间窗: up to 3 months after stroke onset

A hemorrhagic event, judged to be nontraumatic, that results in intraocular bleeding causing loss of vision, the need for a transfusion of two or more units of red cells or the equivalent amount of whole blood, or the need for hospitalization or prolongation of existing hospitalization. This may include bleeding events related to surgical procedures but not those related to accidental trauma. Life-threatening hemorrhagic events will be defined as those that are fatal or require use of intravenous inotropic medication to maintain blood pressure, interventional treatment (including surgical, endoscopic or endovascular interventions), or transfusion of four or more units of red cells or the equivalent amount of whole blood. Non-life-threatening hemorrhagic events will be defined as those classified as major hemorrhagic events but not as life-threatening.

Rate of patients with other serious adverse event under hospital treatment.

时间窗: up to 3 months after stroke onset

Any adverse event, not belonging to the other outcome event categories, that is fatal or life threatening, is permanently or substantially disabling, requires or prolongs hospitalization, results in a congenital anomaly, or requires intervention to prevent permanent impairment or damage.

Rate of patients with neurological deterioration under hospital treatment.

时间窗: up to 3 months after stroke onset

Rapid worsening of an existing focal neurological deficit or rapid onset of a new focal neurological deficit (≥ 24 hours) that is clinically judged by the Investigator not to be attributable to non-ischemic etiology.

Rate of patients with new ischemic stroke under hospital treatment.

时间窗: up to 3 months after stroke onset

* Rapid onset of a new focal neurological deficit with clinical or imaging evidence of infarction and not attributable to a non-ischemic etiology (not associated with brain infection, trauma, tumor, seizure, severe metabolic disease, or degenerative neurological disease); or, * Rapid worsening of an existing focal neurological deficit that is judged by the Investigator to be attributable to a new infarction. Criteria for symptoms attributable to new infarction may include symptoms that persist and are judged by the investigator to be attributable to new infarction, imaging evidence of infarction, or no evidence of a non-ischemic etiology.

Rate of patients with symptomatic hemorrhagic transformation of an ischemic stroke under hospital treatment.

时间窗: up to 3 months after stroke onset

Imaging evidence (by CT or MR) of extravascular blood within the area of infarction, and symptoms judged to be related to the hemorrhagic transformation. Scenarios which may be judged as symptomatic: * If blood is already present on imaging at presentation, symptoms are out of proportion to what would be expected for the size and location of the infarct at presentation; * Clinical deterioration, defined by an increase of 4 points or more in the score on the NIHSS or leading to death, occurring after the initial ischemic event, and identified as the result of the hemorrhagic transformation; or * Mass effect secondary to the hemorrhagic transformation causing symptoms.

Rate of patients with ischemic vascular death under hospital treatment.

时间窗: up to 3 months after stroke onset

Death due to ischemic stroke, myocardial infarction, sudden cardiac death, arrhythmia, pulmonary embolism, bowel or limb infarction, or any death not readily attributable to a non-ischemic cause.

Rate of patients with hemorrhagic vascular death under hospital treatment.

时间窗: up to 3 months after stroke onset

Death due to intracranial or systemic hemorrhage.

Rate of patients with symptomatic intracranial hemorrhage under hospital treatment.

时间窗: up to 3 months after stroke onset

Evidence of hemorrhage in the brain parenchyma or extraparenchymal spaces demonstrated by head imaging, surgery, or autopsy, which is not in the same territory of an underlying acute or subacute ischemic stroke, and is judged to be associated with any new neurologic symptoms (including headache) or leading to death.

Rate of patients with coronary revascularization without myocardial infarction under hospital treatment.

时间窗: up to 3 months after stroke onset

Documented coronary angioplasty, stenting, or bypass surgery for demonstrated or presumed coronary artery disease.

Rate of patients with minor hemorrhage other than intracranial hemorrhage under hospital treatment.

时间窗: up to 3 months after stroke onset

All hemorrhagic events leading to interruption of therapy or discontinuation of the study drug but not classifiable as major hemorrhagic events. This may include bleeding events related to surgical procedures but not those related to accidental trauma.

次要结局

  • Evaluation by an independent investigator(up to 3 months after stroke onset)
