CLINICIAN’S CORNER
The Seventh Report of the Joint
National Committee on Prevention,
Detection, Evaluation, and Treatment
of High Blood Pressure
The JNC 7 Report
“The Seventh Report of the Joint National Committee on Prevention, De-
tection, Evaluation, and Treatment of High Blood Pressure” provides a new
guideline for hypertension prevention and management. The following are
the key messages: (1) In persons older than 50 years, systolic blood pres-
sure (BP) of more than 140 mm Hg is a much more important cardiovascular
disease (CVD) risk factor than diastolic BP; (2) The risk of CVD, beginning
at 115/75 mm Hg, doubles with each increment of 20/10 mm Hg; individu-
als who are normotensive at 55 years of age have a 90% lifetime risk for
developing hypertension; (3) Individuals with a systolic BP of 120 to 139
mm Hg or a diastolic BP of 80 to 89 mm Hg should be considered as pre-
hypertensive and require health-promoting lifestyle modifications to pre-
vent CVD; (4) Thiazide-type diuretics should be used in drug treatment for
most patients with uncomplicated hypertension, either alone or combined
with drugs from other classes. Certain high-risk conditions are compelling
indications for the initial use of other antihypertensive drug classes (angio-
tensin-converting enzyme inhibitors, angiotensin-receptor blockers, ␤-block-
OR MORE THAN 3 DECADES, THENational Heart, Lung, and ers, calcium channel blockers); (5) Most patients with hypertension will re-
quire 2 or more antihypertensive medications to achieve goal BP (Ͻ140/90
mm Hg, or Ͻ130/80 mm Hg for patients with diabetes or chronic kidney
disease); (6) If BP is more than 20/10 mm Hg above goal BP, consideration
should be given to initiating therapy with 2 agents, 1 of which usually should
be a thiazide-type diuretic; and (7) The most effective therapy prescribed by
the most careful clinician will control hypertension only if patients are mo-
organizations and 7 federal agencies.
One important function is to issue tivated. Motivation improves when patients have positive experiences with
and trust in the clinician. Empathy builds trust and is a potent motivator.
Finally, in presenting these guidelines, the committee recognizes that the
responsible physician’s judgment remains paramount.
