Blood Pressure Targets
Still Struggling for the Right Answer
Magdy El-MasryProf. of CardiologyTanta University
The multitude of guidelines from respected professional bodies and
individuals have caused, in my opinion, needless confusion bordering on chaos.

A Flurry of Guidelines for High Blood Pressure Management
“Flurry of guidelines, which offer different
recommendations on BP targets.”
*ADA: < 140/80
**KDIGO: <140/90 w/o albuminuria ≤130/80 if >30 mg/24hr
Hypertension Goals of Various Organizations
JNC 7 recommended a treatment threshold of 140/90 mm Hg regardless of age, whereas JNC 8 raises the systolic threshold at age 60.
In addition, JNC 7 recommended a lower treatment threshold (130/80 mm Hg) for patients with diabetes or chronic kidney disease, but JNC 8 does not.

Proportion of US Adults Potentially Affected by the 2014 Hypertension Guideline
JAMA. 2014;311(14):1424-1429.
If the JNC 8 recommendations are used, 6 million adults in the US aged 60 years and older would be ineligible for treatment with antihypertensive drugs,
and treatment intensity would be decreased for an additional 13.5 million older persons,
leading to increased incidences of coronary events, stroke, heart failure, cardiovascular mortality, and other adverse events associated with inadequate control of hypertension.
Impact of the 2014 Expert Panel Recommendations for Management of High Blood Pressure on Contemporary Cardiovascular Practice : Insights From the NCDR PINNACLE RegistryJ Am Coll Cardiol. 2014 Dec 2;64(21):2196-203
Of 1,185,253 patients in the study cohort, 706,859 (59.6%) achieved the 2003 JNC-7 goals. Using the 2014 recommendations, 880,378 (74.3%) patients were at goal.
Among U.S. ambulatory cardiology patients with hypertension, nearly 1 in 7 who did not meet JNC-7 recommendations would now meet the 2014 treatment goals.

The International Verapamil SR-Trandolapril Study (INVEST)
8,345 Patients 60 years of age or older with CAD and baseline SBP >150 mm Hg randomized to a treatment strategy on the basis of either atenolol/hydrochlorothiazide or verapamil-SR /trandolapril were categorized into 3 groups on the basis of achieved on-treatment SBP: group 1, <140 mm Hg; group 2, 140 to <150 mm Hg; and group 3, ≥150 mm Hg.

Study Design and Main Outcomes
Patients who achieved a systolic blood pressure <140 mm Hg had the lowest rate of the primary outcome, cardiovascular mortality, and fatal and nonfatal stroke compared with the groups with achieved systolic blood pressure≥140 mm Hg. BP = blood pressure; CV = cardiovascular; INVEST= INternational VErapamil SR Trandolapril STudy; MI = myocardial infarction; SBP = systolic blood pressure.
Figure Legend:
In hypertensive patients with CAD who are ≥60 years of age, achieving a SBP target of 140 to <150 mm Hg as recommended by the JNC-8 panel was associated with less benefit than the previously recommended target of <140 mm Hg.
“New Hypertension Recommendations Anticipated in 2016”
The AHA and the ACC, in collaboration with nine other medical societies, will be releasing new hypertension guidelines that will serve as an update to those released by the JNC 7 in 2003.

BP Goals
March 31, 2015
Goals for target BP level or reduction from pretreatment baseline are uncertain and should be individualized, but it is reasonable to achieve a SBP<140 mm Hg and a DBP<90 mm Hg
(Class IIa; Level of Evidence B). For patients with a recent lacunar stroke, it might be
reasonable to target a SBP of <130 mm Hg (Class IIb;Level of Evidence B).
2014
There is no consensus among new HTN practice guidelines as to target treatment BP among various subpopulations of patients.
While most guidelines have a target BP < 140/90 for the general population, the JNC-8 task force favors a target BP < 150/90 mm Hg for persons age ≥ 60y.
Most guidelines now target a BP < 150/90 for
persons age ≥ 80y.
Most guidelines now target a BP < 140/90 for patients with diabetes or CKD, while a few others target a BP < 130/80 if diabetes, albuminuria, or high stroke risk is present.
What are the current blood pressure targets?
BP goals in patients with CADAHA/ACC/ASH 2015
• The <140/90 mm Hg BP target is reasonable for the secondary prevention of CVD in patients with hypertension and CAD.
• A lower target BP of <130/80 mm Hg may be appropriate in some individuals with CAD or those with previous MI, stroke, or transient ischemic attack, or CAD risk equivalents (carotid artery disease, peripheral arterial disease, or abdominal aortic aneurysm).
• A BP goal of <150/90 mm Hg is recommended in those who are >80 years of age
