Approximately 25% of patients with known hypertension have their condition
under control. Multiple blood pressure measurements should be obtained before
making the diagnosis. Several patients have labile blood pressures, and experience
white coat hypertension in the office. Although these patients are at
higher risk for developing sustained hypertension later in life, they do
not need medical treatment for labile blood pressures alone. Hypertension
is known as the silent killer, because affected patients are usually
asymptomatic until complications occur.1
- Only approximately 10% of patients on medical therapy for hypertension
have their blood pressure controlled to less than 140/90 mm Hg.
