The survival time of hypertensive patients with a high pressure of 170 mmHg is related to the specific situation and cannot be generalized. Patients with systolic blood pressure as high as 170mmHg indicate a more serious condition. If the blood pressure is at such a high level for a long time, it may induce renal failure, heart failure, fundus lesions, etc., and may even cause cerebrovascular accidents such as cerebral hemorrhage. It is recommended that the patient go to the cardiovascular medicine department in time to find out the cause of the disease and take medication regularly for a long period of time under the guidance of the doctor, so that the blood pressure can be controlled at the appropriate level. If the patient’s blood pressure is under good control and there are no other complications, the patient’s life expectancy will not be affected and he or she can survive for a long time. If the patient does not take the medication as prescribed by the doctor, and the treatment is not active, and if the patient allows it to continue to develop, once it induces a cerebrovascular accident, the patient’s life may be in danger at any time. Therefore, patients need to actively improve their lifestyles, quit smoking and drinking, eat a balanced diet, and limit salt to less than 6g per day, reduce fat intake and increase the intake of fresh vegetables.
