The current blood pressure measured in the elderly is 150/58mmHg, the current high pressure is high, the low pressure is low, and the pulse pressure difference is too large. At present, the causes of excessive pulse pressure difference (such as senile hypertension, aortic valve insufficiency, hyperthyroidism, severe anemia, etc.) should be treated with medication, surgery, etc., and it is not recommended to take blood pressure medication rashly. 1. Geriatric hypertension: Excessive pulse pressure difference can lead to an increased risk of cardiovascular and cerebrovascular diseases. Patients may also experience dizziness and headache, panic and shortness of breath. In this case, it can be controlled by taking diuretics such as hydrochlorothiazide as prescribed by the doctor. 2. Aortic valve insufficiency: This can also lead to an increase in the pulse pressure difference. If the situation permits, it can be controlled with medicines such as Nitrendipine as prescribed by the doctor. In severe cases, valve replacement through surgery is needed. 3. Hyperthyroidism: For patients with hyperthyroidism, drugs such as methimazole should be used as prescribed by the doctor for control. It is not recommended to increase antihypertensive drugs. 4. Severe anemia: in order to ensure the oxygen supply of the body, the systemic blood circulation is not accelerated, the systolic blood pressure will rise and the pulse pressure difference will increase. Those who are diagnosed need to take iron supplementation drugs to control blood pressure, and cannot increase antihypertensive drugs rashly. Elderly people with abnormal blood pressure and large pulse pressure difference may have other reasons, they should go to regular hospitals in time to find out the cause of the disease and actively treat it. The above drugs need to be standardized use under the guidance of a doctor.
