Hypertension can be diagnosed by examinations of blood pressure.

Confirm if there exists hypertension:

Test blood pressure with hemodynamometer for several days continuously and if there are more than twice rise in blood pressure, hypertension can be diagnosed.

Blood pressure value:

Type	Systolic pressure(mmHg)	Diastolic pressure (mmHg)
Normal pressure	<120	<80
Normal high value	120 - 139	80 - 89
High blood pressure	≥140	≥90
Hypertension level 1 (mild)	140 - 159	90 - 99
Hypertension level 2 (moderate)	160 - 179	100 - 109
Hypertension level 3 (severe)	≥180	≥110
Isolated systolic hypertension	≥140	<90

If patients’ systolic pressure and diastolic pressure belong to different level, subject to the higher grading standard.

The isolated systolic hypertension can be divided into level 1, 2 and 3 according to the systolic pressure level.

Grading standard of cardiovascular risk of patients with hypertension:

Other risk factors and medical history	Blood pressure level
	Level 1	Level 2	Level 3
No other risk factors	Low	medium	High
1-2 risk factors	Moderate	Moderate	Extreme high risk
≥3 risk factors or diabetes mellitus or target organ damages	High	High	Extreme high risk
Complications	Extreme high risk	Extreme high risk	Extreme high risk
