According to the diagnostic criteria for hypertension, diastolic blood pressure in patients with a low pressure of 95 is considered mild hypertension. In the absence of antihypertensive medication, blood pressure was measured once daily for three days, respectively, and hypertension was diagnosed if systolic blood pressure was ≥140 mmHg and/or diastolic blood pressure was ≥90 mmHg. Patients with a previous history of hypertension, who have received regular blood pressure lowering treatment, were diagnosed with hypertension despite a blood pressure <140/90 mmHg. Blood pressure levels in the population are continuously normally distributed, and there is no clear boundary between normal blood pressure and elevated blood pressure, and the criteria for hypertension are defined based on clinical and epidemiological data. (Chinese hypertension prevention and treatment guideline criteria: Currently, China uses normotension (systolic blood pressure <120 mmHg and diastolic blood pressure <80 mmHg), normal high [systolic blood pressure 120-139 mmHg and/or diastolic blood pressure 80-89 mmHg] and hypertension [systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg] for blood pressure level classification.) Hypertension was further classified into three classes according to the level of elevated blood pressure. Class I hypertension (mild) is systolic blood pressure 140-159 mmHg and/or diastolic blood pressure 90-99 mmHg; Class II hypertension (moderate) is systolic blood pressure 160-179 mmHg and/or diastolic blood pressure 100-109 mmHg; Class III hypertension (severe) is systolic blood pressure ≥180 mmHg and/or diastolic blood pressure ≥110 mmHg. (Note: When systolic and diastolic blood pressure are classified (Note: When systolic and diastolic blood pressure are in different grades, the higher classification prevails.) The above criteria apply to men and women over 18 years of age, while children use the 95th percentile of blood pressure values for different age groups, usually below adult levels. It should be noted that the above blood pressure values are office blood pressure, and in the case of home self-measured blood pressure, the diagnostic criteria for hypertension is ≥135/85 mmHg, which corresponds to 140/90 mmHg for office blood pressure. The diastolic blood pressure in patients with a low pressure of 95 is considered mild hypertension. How to treat depends on whether there is a combination of clinical disease and risk factors. If there is no combination of clinical disease and risk factors, the patient is at low risk and treatment is based on lifestyle improvement. If there are risk factors or a combination of clinical disease, pharmacological treatment needs to be initiated.
