What is borderline hypertension?

 Borderline hypertension is also called borderline hypertension. Its systolic blood pressure is 18.6-21.3kpa (140-160mmhg), diastolic blood pressure is 12.0-12.6kpa (90-95mmhg). This disease is characterized by slightly higher blood pressure, no organic damage to the important organs, such as heart, brain and kidney, but it is easy to develop into hypertension. Clinical observation showed that 71.5% of borderline hypertension patients were easy to develop hypertension, while only 11.1% of normal people. The incidence of cerebral hemorrhage, cerebral thrombosis, coronary heart disease, and the mortality were similar to those of patients with hypertension, and significantly higher than those of normal people. Because it has no organic damage in the early stage, and lacks specific symptoms and signs, it is easy to be ignored. The prevention of this kind of hypertension is the same as that of general hypertension. However, the key is to control sodium intake, preferably less than 5g per day, and increase potassium intake, such as eating more fruits and vegetables. In addition, we should insist on sports and take calcium antagonists for a long time if necessary.
