The World Health Organization has estimated that high blood pressure
causes 1 in every 8 deaths worldwide, making hypertension the third leading
killer in the world.1 The JNC 7 report,2 published in this issue of THE JOURNAL, summarizes
how the burden of hypertension can be decreased. Among the messages emphasized
is that systolic blood pressure control should be the focus of treatment.
Cardiovascular risk from systolic hypertension begins at 115 mm Hg and risk
from diastolic hypertension begins at 75 mm Hg. Individuals who are normotensive
at 55 years have a 90% likelihood of developing high blood pressure during
the next 25 years, and lowering blood pressure toward the new goal level of
120/80 mm Hg will decrease heart attacks, heart failure, stroke, kidney disease,
and will save lives.
