White
coat hypertension (WCH) is the situation in which an individual has high blood
pressure (BP) in the medical office (BP >140/90) and normal BP outside the office (BP <135/85). Masked hypertension (MHT) is the opposite of WCH, i.e.,
a situation in which a person has normal BP in the office and high BP outside
of it.

The overall prevalence of WCH is approximately 15%. However, in extreme
situations, as in the case of suspected resistant hypertension, the prevalence
of WCH reaches 40%. Among the many indications of Ambulatory Blood Pressure
Monitoring (ABPM), the main one is to assess patients with suspected WCH , being
also indicated to evaluate the white coat effect on hypertensive patients using
antihypertensive drugs, whose BP levels measured in the office remain high
despite anti-hypertensive therapy. As the white-coat effect is common among the
elderly, this is a group where this assessment is often indicated. Read more>>>>>>>>>>
