How long a patient can live with cerebral infarction due to atrial fibrillation is mainly related to the severity of the patient’s disease. It can be considered from the following aspects: 1. If the thrombus shed by atrial fibrillation is relatively large, resulting in infarction of the large blood vessels of the patient’s brain, causing a large area of cerebral infarction in the patient, the survival time of the patient is usually judged specifically according to the patient’s specific situation. It is also closely related to the medical level of the hospital where the patient is treated. If the patient has taken timely debridement and decompression surgery after the discovery of the disease, the patient can live from six months to one year. If the patient is in good condition, he or she can live for a longer period of time. However, if the patient does not take the bone flap decompression surgery in time for treatment. 2.If the infarction area of cerebral infarction caused by atrial fibrillation is relatively small, it usually does not cause the patient to die, and through active treatment, the patient’s symptoms can be improved to a certain extent.
