Masked hypertension may go undetected and untreated for some time, resulting in end-organ damage.

Criteria for masked hypertension:

(1) blood pressure that is not elevated (< 140/90 mm Hg) when measured by a healthcare professional

(2) blood pressure is elevated when it is measured elsewhere (at home, ambulatory, other)


The presence of certain risk factors should prompt the clinician to monitor home or ambulatory blood pressures:

(1) high normal blood pressure

(2) smoking

(3) excessive alcohol use

(4) oral contraceptives in females

(5) diabetes

(6) renal disease

(7) sedentary lifestyle

(8) excessive stress

(9) family history of hypertension

(10) obesity

(11) tachycardia

(12) unexplained left ventricular hypertrophy

(13) past history of elevated blood pressure readings

(14) obstructive sleep apnea
