Mild cerebral infarction will be effective in about 2-3 days of infusion. The area of blocked blood vessels in mild cerebral infarction is very small. There will be no obvious symptoms clinically, or the patient will only have mild unfavorable limb movement, numbness, and crookedness of the mouth. In the acute stage, by activating blood circulation and improving blood supply to the brain, the semidark band of ischemic tissue can be saved and the patient’s symptoms can be significantly relieved. The occurrence of mild cerebral infarction is mainly related to the hardening and occlusion of small arteries in the cerebral arteries. Therefore, patients should usually target hypertension, diabetes, hyperlipidemia and other diseases for effective control, and take long-term oral BAY aspirin to antiplatelet aggregation and prevent recurrence of cerebral infarction.
