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-

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.
