Not all cerebral insufficiency of blood supply will develop into cerebral infarction, and the time of its occurrence is related to the cause of cerebral insufficiency of blood supply and prevention, treatment, etc. There is no specific time.
Cerebral blood supply insufficiency can be seen in head and neck artery atherosclerosis plaque formation and stenosis and other diseases, in addition to heart failure, anemia, chronic obstructive pulmonary disease may also lead to cerebral blood supply insufficiency.
For example, if patients with carotid plaques have stable plaques and timely prevention, such as low-salt and low-fat diets and blood glucose control, cerebral infarction may not occur; if the plaques are unstable, rupture, dislodgement, and thrombosis, cerebral infarction may occur, but there is no clear correlation with the time, and it is related to the status of plaques and whether or not relevant treatments have been carried out.
Patients with heart failure may also have insufficient cerebral blood supply. Simple cardiac insufficiency does not usually lead to cerebral infarction, but cerebral infarction can occur if it is accompanied by atrial fibrillation and other cardiac arrhythmia, which produces thrombus, and if the thrombus is dislodged.
If cerebral blood supply insufficiency occurs, it is recommended to seek timely medical treatment.
