Definition of hypertension subtypes

Hypertension by office blood pressure
	Patients with office blood pressure ≥ 140/90 mmHg
Masked hypertension
	Patients with office blood pressure < 140/90 mmHg and
	24-Hour averaged blood pressure ≥ 130/80 mmHg and/or
	Daytime averaged blood pressure ≥ 135/85 mmHg and/or
	Nighttime averaged blood pressure ≥ 120/70 mmHg
White-coat hypertension
	Patients with elevated office blood pressure
	≥ 140/90 mmHg and
	24-Hour averaged blood pressure < 130/80 mmHg and
	Daytime averaged blood pressure < 135/85 mmHg and
	Nighttime averaged blood pressure < 120/70 mmHg
Sustained hypertension
	Patients with office blood pressure ≥ 140/90 mmHg and
	24-Hour averaged blood pressure ≥ 130/80 mmHg and/or
