Normal blood pressure in adults should be <140 mmHg systolic and <90 mmHg diastolic. The current diagnostic criteria for hypertension are a systolic blood pressure of ≥140 mmHg and a diastolic blood pressure of ≥90 mmHg on three or more occasions at rest within the same day, while the ideal systolic blood pressure should be <120 mmHg and diastolic blood pressure <80 mmHg. If the systolic blood pressure exceeds the ideal blood pressure level but does not meet the diagnostic criteria for hypertension, the blood pressure is considered to be normally high. People with high normal blood pressure are more likely to experience cardiovascular events than those with normal blood pressure, and should be proactively intervened with to improve poor lifestyle. It is recommended to seek prompt medical attention and standardized treatment when necessary.
