Disclosures
• I have no actual or potential conflicts of
interest to disclose in relation to this
presentation
Objectives
• Briefly review the Institute of Medicine
Report (2011) guideline standards
• Identify modifications in JNC8 and the impact
on hypertension management
• Review the ACC/AHA Blood Cholesterol
Guidelines and related hyperlipidemia
treatment
• Evaluate clinical controversies surrounding
the release of both JNC8 and ACC/AHA Blood
Cholesterol Guidelines
Institute of Medicine Report (2011)- Clinical
Practice Guidelines We Can Trust
• CPGs (clinical practice guidelines) may reduce
inappropriate practice variation, enhance translation
of research to practice, and improve healthcare quality
• Lack of transparency, inconsistent methodology, failure
to seek stakeholder input
• IOM recommended 8 best practice standards for
developing CPGs

No, JNC what??
Why do we care?
• About 70 million American adults (29%) have high blood
pressure—that’s 1 of every 3 adults.
• Only about half (52%) of people with high blood pressure
have their condition under control.
• Nearly 1 of 3 American adults has prehypertension—blood
pressure numbers that are higher than normal, but not yet
in the high blood pressure range.
• High blood pressure costs the nation $46 billion each year.
This total includes the cost of health care services,
medications to treat high blood pressure, and missed days
of work.
http://www.cdc.gov/bloodpressure/facts.htm
JNC 8
• Consists of 9 recommendations
• Evidence review limited to random controlled trials
(RCT)
• Following 3 questions guided the evidence review:
1. In adults with hypertension, does initiating
antihypertensive pharmacologic therapy at specific BP
thresholds improve health outcomes?
2. In adults with hypertension, does treatment with
antihypertensive pharmacologic therapy to a specified BP
goal lead to improvements in health outcomes?
3. In adults with hypertension, do various antihypertensive
drugs or drug classes differ in comparative benefits and
harms on specific health outcomes?

4 classes and doses based
on RCT evidence
JNC 8: Recommendation 1
In the general population aged ≥ 60 years,
initiate pharmacologic treatment to lower
BP at SBP ≥ 150 mmHg or DBP ≥ 90 mmHg
and treat to a goal SBP < 150 mmHg and
goal DBP <90 mmHg.
Strong Recommendation: Grade A
JAMA. 2014;311(5):507-520.

In the general population aged ≥ 60 years, if
pharmacologic treatment for high BP results
in lower achieved SBP (eg, <140 mmHg) and
treatment is well tolerated and without
adverse effects on health or quality of life,
treatment does not need to be adjusted
Expert Opinion: Grade E

JAMA. 2014;311(5):507-520.
JNC 8: Recommendation 6
In the general nonblack population, including
those with diabetes, initial antihypertensive
treatment should include a thiazide-type
diuretic, calcium channel blocker (CCB),
angiotensin-converting enzyme inhibitor
(ACEI), or angiotensin receptor blocker (ARB).
Moderate Recommendation: Grade B
*Note: No Beta Blockers
JAMA. 2014;311(5):507-520.
JNC 8: Recommendation 7
In the general black population, including
those with diabetes, initial antihypertensive
treatment should include a thiazide-type
diuretic or CCB.
General black population, Moderate Recommendation: Grade B
Black patients with diabetes, Weak Recommendation: Grade C
JAMA. 2014;311(5):507-520.
JNC 8: Recommendation 8
In the population aged ≥ 18 years with CKD,
initial (or add-on) antihypertensive
treatment should include an ACEI or ARB to
improve kidney outcomes. This applies to
all CKD patients with hypertension
regardless of race or diabetes status.
Moderate recommendation: Grade B
JAMA. 2014;311(5):507-520.
JNC 8: Recommendation 9
• The main objective of hypertension treatment is to attain and
maintain goal BP.
• If goal BP is not reached within a month of treatment,
increase the dose of the initial drug or add a second drug from
one of the classes in recommendation 6 (thiazide-type
diuretic, CCB, ACEI, or ARB).
• If goal BP cannot be reached with 2 drugs, add and titrate a
third drug from the list.
• May use antihypertensives from other classes if goal BP
cannot be reached using recommended drug classes because
of contraindication or need to use more than 3 drug classes to
reach goal BP
• Do NOT use ACEI and ARB together
JAMA. 2014;311(5):507-520.

Old vs New
Old Guidelines
• Treat to target LDL
• Use of multiple drug
classes to achieve LDL goal
• Monitor lipids to assess if
at goal
New Guidelines
• Assess cardiovascular risk
• Most benefit from statin
use
• Instead of treating to LDL
target, more important to
start statin dose to reduce
CV risk
• Monitoring only for
tolerability and adherence
to therapy

2013 ACC/AHA Guidelines
• Goals:
• Prevent cardiovascular diseases
• Improve the management of people who have these diseases
through professional education and research
• Develop guidelines, standards, and policies that promote optimal
patient care and cardiovascular health
• Reviewed RCTs and systemic reviews and meta-analyses of
RCTs with ASCVD outcomes
• Atherosclerotic cardiovascular disease (ASCVD) defined as:
• Coronary heart disease (CHD)
• Stroke
• Peripheral arterial disease (PAD)
2013 ACC/AHA Guidelines
• Lifestyle as the Foundation for ASCVD RiskReduction Efforts
• Lifestyle modification remains crucial (diet, exercise,
avoiding tobacco, and healthy weight)
• Emphasize before and during treatment
2013 ACC/AHA Guidelines:
4 Major Statin Benefit Groups
Clinical

LDL-C > 190
mg/dL
DM, 40-75
years, LDL 70190

ACC/AHA Recommendations
• Treatment Targets
• No recommendation on LDL or HDL targets
• Secondary Prevention
• High intensity statin for anyone age ≤ 75 years (A:
strong)
• Moderate intensity statin if contraindicated (A:
strong)
• For those >75 years, assess risk vs benefit of starting
high intensity or moderate intensity statin and of
continuing statin therapy (E: Expert Opinion)
ACC/AHA Recommendations
• Primary Prevention: age ≥ 21 years with
LDL ≥ 190 mg/dL
• Evaluate for secondary causes of hyperlipidemia for
LDL >190 or TG >500 (B: Moderate)
• High intensity statin regardless of 10-yr ASCVD risk,
or maximally tolerated statin (B: Moderate)
• Intensify statin therapy to achieve a 50% LDL
reduction (E: Expert Opinion)
• May consider adding non statin therapy for further
LDL reduction after maximum benefit from statin is
achieved (E: Expert Opinion)
ACC/AHA Recommendation
• Primary Prevention: DM and LDL 70-189
mg/dL
• Moderate intensity statin should be initiated or
continued for adults 40-75 years with DM (A: Strong)
• High intensity statin reasonable for 10-yr ASCVD risk
≥ 7.5% (E: Expert Opinion)
• Evaluate potential for ASCVD benefits for those with
DM < 40 years of age or >75 years (E: Expert
Opinion)
ACC/AHA Recommendation
• Primary Prevention: without DM and LDL 70189 mg/dL
• Estimate 10-yr ASCVD risk to guide initiation of statin
therapy (E: Expert Opinion)
• 10-yr ASCVD risk ≥ 7.5% treat with moderate-high
intensity statin (A: Strong)
• 10-yr ASCVD risk 5-7.5% reasonable to offer moderate
intensity statin (C: Weak)
• Before starting statin, engage in discussion with patient
regarding risk vs benefit (E: Expert Opinion)
• For those not identified in statin benefit group, or risk is
uncertain, additional factors may be considered (E:
Expert Opinion)
Additional factors to consider
• For individuals who do not fit into 1 of the 4 benefit
groups, the factors listed below may be considered to
make a treatment decision:
• LDL-C ≥160 mg/dL or evidence of genetic hyperlipidemia
• History of premature ASCVD with onset <55 yrs in first degree
male relative or <65 yrs in first degree female relative
• High-sensitivity C-reactive protein ≥2 mg/L
• Coronary artery calcium score ≥300 Agatson units or ≥75
percentile for age, sex, and ethnicity
• Ankle-brachial index <0.9
• Elevated lifetime risk of ASCVD
ACC/AHA Recommendation
• Heart Failure and Hemodialysis
• No recommendation regarding initiation or
discontinuation of statins in patients with NYHA
class II-IV ischemic systolic heart failure or
maintenance hemodialysis (N: No Recommendation)
ASCVD 10 year risk
• Clear net benefit of initiation of moderate-tohigh-intensity statin therapy with a risk of
>7.5%.
• When risk is between 5.0-7.5% there is still
net absolute benefit with moderate intensity
statin – need to discuss with patient the risk
and benefits of treatment.

Recommendations, cont.
ACC/AHA Recommendation:
Nonstatin Use
• Before adding nonstatin, reemphasize adherence to
lifestyle changes and statin therapy
• No data supporting routine use of nonstatin drugs +
statin to reduce ASCVD events
• No RCTs assess ASCVD outcomes in statin-intolerant
patients
• May consider in high risk individuals
• ASCVD
• LDL ≥ 190
• DM aged 40-75 years
Monitoring Therapeutic Response and Adherence
ACC/AHA Summary
• No longer treat to a target number
• Now target four focus groups:
•
•
•
•
With clinical ASCVD
LDL-C ≥190 mg/dL
Diabetes aged 40-75
Estimated 10-year ASCVD risk ≥ 7.5%
• Try to treat with maximum tolerated intensity of statin
that is recommended
• Goal of LDL-C reduction by ≥50% with high intensity
therapy or by 30-50% with moderate intensity therapy
• Monitoring is done to assess response and adherence
And the controversy
continues…
ACC/AHA 2013 Cholesterol
Guidelines
Pros
• Fairly clear steps of
identify risk group,
assess need for statin
and intensity
• May help reduce undertreatment
• Less monitoring
necessary

Cons
What about patients who
can’t tolerate any statins?
Some prefer treat to

Summarize
“… recommendations are not a substitute for clinical
judgment, and decisions about care must carefully
consider and incorporate the clinical characteristics and
circumstances of each individual patient.” from JNC 8
• National guidelines help guide care with evidencebased practice
• Must consider each individual patient and assess risk
vs benefit
