3. Screening for Hypertension

Screening for hypertension is recommended for all children and adults
(see Clinical Intervention).
Burden of Suffering
Hypertension is usually defined as a diastolic blood pressure of 90 mm Hg
or higher or a systolic pressure of 140 mm Hg or higher.1 It is present in
an estimated 43 million Americans and is more common in blacks and
older adults.1a Hypertension is a leading risk factor for coronary heart disease, congestive heart failure, stroke, ruptured aortic aneurysm, renal disease, and retinopathy. These complications of hypertension are among the
most common and serious diseases in the U.S., and successful efforts to
lower blood pressure could thus have substantial impact on population
morbidity and mortality. Heart disease is the leading cause of death in the
U.S., accounting for nearly 740,000 deaths each year (287 deaths per
100,000 population), and cerebrovascular disease, the third leading cause
of death, accounts for about 150,000 deaths each year (58/100,000).2
Milder forms of hypertension predict progression to more severe elevations and development of cardiovascular disease.1,3,4 Coronary heart disease mortality begins to increase at systolic blood pressures above 110 mm
Hg and at diastolic pressures above 70 mm Hg.5 The prevalence of unrecognized and uncontrolled hypertension, and the mortality from cardiovascular disease, have declined substantially in the U.S. in the past several
Treatable (also known as secondary) causes of hypertension such as
aortic coarctation or renovascular disease also may be associated with severe consequences, including congestive heart failure, aortic rupture, or
stroke.6–9 There are no population data available for estimating the true
prevalence of secondary hypertension. The incidence of coarctation of the
aorta has been estimated at 0.2–0.6/1,000 live births and the prevalence at
0.1–0.5/1,000 children.10–12
