The mortality rate of cerebral infarction is very high. In our disease spectrum, the mortality rate of cardiovascular and cerebrovascular diseases is higher than that of tumors, and the mortality rate of cerebrovascular diseases should be the highest among single diseases, which is why the country has attached great importance to stroke over the years. This is why the state has attached great importance to stroke over the years. The state has set up a brain prevention committee, base hospitals and appropriate technologies, including stroke centers, because the incidence of stroke is very high, and the mortality rate is also very high, and once it occurs, it is the first disabling factor. If one person in a family has a stroke and becomes disabled, it can have a great impact on the whole family and on society. To prevent this type of disease, which has a very high mortality rate, it is important to find out which patients are prone to stroke and to intervene appropriately in people who are at high risk of developing stroke.
