Exploratory Study on the Effects of Early Rosuvastatin Treatment in Patients With Acute Ischemic Stroke

This is an exploratory, randomized, open-label, 2-arm, parallel-group study exploring the efficacy of rosuvastatin (20mg/day) in patients with acute ischemic stroke.

This is a 90-day, explanatory; randomized; open-label, 2-arm; parallel group with blinded outcome evaluation study exploring the efficacy and study of early rosuvastatin 20 mg/d treatment in acute ischemic patients with stroke onset in 24 hours.

Inclusion Criteria:

1. 45 to 75 years old patients;
2. Stroke involving the vascular territory of the middle cerebral artery (MCA) as judged by clinical and MRI evidences;
3. Time from symptom onset to take the study assigned medication is within 24 hours;
4. Statin naïve or discontinued at least 3 month before stroke onset;
5. First ever stroke or mild sequelae (with modified Rankin Score 0-1) before the index event;
6. Moderate neurological deficit with baseline NIHSS scoring from 4-20;
7. MRI scans （T1W1、T2W2、T2Flair、DWI、SWI）accomplished from 12 to 48 hours after the onset;
8. Consent form signed.

Exclusion Criteria:

-

Any of the following is regarded as a criterion for exclusion from the study:

1. Stroke involving the vascular territory of the vertebrobasilar artery as judged by clinical and MRI evidences;
2. Hemorrhagic transformation or intracranial hemorrhage on baseline MRI. MRI performed between 12-48 hours after the onset, if MRI provides evidences which met with the exclusion criteria, the patients will be excluded from the study;
3. Any circumstances under which MRI scans can't be performed;
4. Evidences suggesting cardiogenic stroke such as atrial fibrillation, acute coronary syndrome, patent foramen ovale , etc;

8. Receiving medication with possible neuroprotective functions after stroke onset;
9. Currently take steroids therapy;
10. Diagnosed with malignancy within 5 years;
11. Patients with myopathy or serum creatine kinase > 3 times the upper limit of normal not caused by myocardial injury;
12. Severe renal function damage (eGFR<30);
13. Concurrent use ciclosporin;
14. A history of hypersensitivity of statins and other severe complication;
15. Child-bearing women ;
