Blood pressure appears high pressure 150mmHg low pressure 70mmHg if for young patients is generally not dangerous, but the elderly patients are more serious. Normal blood pressure is high pressure 120mmHg, low pressure 80mmHg, if the blood pressure high pressure 150mmHg low pressure 70mmHg, generally only a mild increase, at the same time, if the young patients, may be caused by the exercise of transient blood pressure, pay attention to lifestyle regulation, proper rest, reduce sodium intake can be relieved. However, high pressure (systolic) of 150mmHg and low pressure (diastolic) of 70mmHg in elderly patients is called simple systolic hypertension, which leads to greater impact on the cerebral blood vessels, easily causing cerebral atherosclerosis, or acute cerebral hemorrhage, which is more dangerous. Simple systolic hypertension with high pulse pressure difference should be taken seriously in the clinic, and must be actively treated and develop good dietary habits, and the changes in blood pressure should be monitored regularly, and proper treatment should be carried out under the guidance of the doctor to keep the blood pressure and pulse pressure as stable as possible.
