How long the life expectancy of smog disease is usually related to the severity of the disease, the timeliness of the treatment, the effect of the treatment, etc., and cannot be generalized. Smokers’ disease is dominated by cerebral ischemia caused by internal carotid artery occlusion and cerebral hemorrhage induced by rupture of compensatory dilated smoky blood vessels, and clinically manifests as transient ischemic attack, cerebral infarction, cerebral hemorrhage, subarachnoid hemorrhage, epilepsy, and other symptoms. Smokey’s disease is a chronic progressive disease, if the patient has a large cerebral infarction, massive cerebral hemorrhage, severe subarachnoid hemorrhage, etc., it may affect the survival period of the patient, which is usually shorter; if transient ischemia and epilepsy are present, the survival period is usually relatively longer. Most patients generally have little impact on life expectancy through aggressive treatment and prevention. Patients with smokers’ disease must seek early medical attention and cooperate with their doctors for active treatment to avoid delays that could lead to aggravation of the disease.
