How long a patient with cerebral infarction diabetes and high blood pressure will live is largely related to the severity of the cerebral infarction and the control of the diabetes and high blood pressure. The life expectancy of patients with better control is generally not affected, but patients in poor condition may be affected. 1. If the condition of patients with cerebral infarction develops relatively mildly, and after timely treatment in regular hospitals, there are no sequelae or some mild sequelae, and at the same time, the patients will control their blood pressure and blood glucose in an appropriate range, the prognosis is usually better, and the life expectancy of the patients in general may not be affected. 2. If the condition of patients with cerebral infarction is serious and the blood pressure and blood sugar are not well controlled, the treatment may lead to recurrence of cerebral infarction and the prognosis is relatively poor, affecting the quality of life of patients. The survival time of patients will be significantly shortened, but the exact survival time cannot be accurately assessed. Patients with cerebral infarction, diabetes mellitus and hypertension should actively improve their lifestyles, quit smoking and drinking, as well as actively treat underlying diseases such as hypertension and diabetes mellitus, and follow doctor’s orders for treatment to improve survival time.
