masked hypertension 


A popular term for a condition in which a patient’s office blood pressure–BP level is <140/90 mm Hg but ambulatory or home BP readings are in the hypertensive range.

Prevalence ±1 in 7 to 8 persons with a normal office BP level may have masked hypertension

Aetiology Daily life stressors, behavioural factors–e.g., smoking, alcohol use, contraceptive use, sedentary habits affecting the patient outside of the clinical setting

Diagnosis Ambulatory or home BP measurement

Risks of masked hypertension Compared to true non-hypertensives, those with masked hypertension have greater organ damage, increased metabolic risk factors, left ventricular mass index, carotid intima-media thickness, and impaired large artery distensibility 

Synonym Out-of-office hypertension
