As long as one suffers from cerebral infarction, it means that there are high-risk factors of cerebrovascular. Even if there is no recurrence for three years, but the prevention work is not done well, there is a possibility of recurrence at a later stage. Some data show that the recurrence rate of cerebral infarction within five years reaches about 26%, so as long as you suffer from cerebral infarction, you must normally take the relevant drugs under the guidance of neurologists to do a good job of secondary prevention. For example, in the absence of contraindications, it is necessary to take regular daily anti-platelet aggregation treatment with aspirin, as well as lipid-lowering and plaque stabilization treatment with oral statins. At the same time, blood pressure, lipids and blood glucose high-risk indicators need to be controlled. Patients who have suffered from cerebral infarction are advised to frequently follow up with the neurology department after discharge from the hospital to adjust the treatment plan according to their condition, which can also reduce the recurrence of cerebral infarction to a great extent.
