Evolving Perspectives on the Role on
Beta-Blockers Across the
Risk Spectrum for Heart Disease

Welcome and Program Overview
CME-accredited symposium jointly sponsored by the University of
Massachusetts Medical School and CMEducation Resources, LLC
Commercial Support: Sponsored by an independent educational grant
from Forest Laboratories
Mission statement: Improve patient care through evidence-based
education, expert analysis, and case study-based management
Processes: Strives for fair balance, clinical relevance, on-label
indications for agents discussed, and emerging evidence and
information from recent studies
COI: Full faculty disclosures provided in syllabus and at the beginning
of the program
Program Educational Objectives
As a result of this educational activity, participants will:
► Learn how to approach hypertension as a systematic disease, with
multiple manifestations, and associations, including assessment of
coexisting conditions that support use of specific classes or agents.
► Learn how to apply evidence-based support for cardioselective betablockers across the cardiovascular disease risk spectrum, including
hypertension, symptomatic CHD, and heart failure.
► Learn how to manage complicated patients with high blood pressure,
including those with ischemic heart disease and/or heart failure.
► Learn about the possible role of the new and emerging beta-1
cardioselective beta-blockers and their role in the management of
hypertension and related cardiovascular disorders, including heart
failure and CVD.

Goal Of Antihypertensive Therapy
►
< 140 mm Hg and < 90 mm Hg for most patients
►
< 130 mm Hg and < 80 mm Hg for diabetics, patients
with HF and those with CRF and any day now for
those with CAD
Goal is not dependent on age, gender or co-morbidity
THE GOAL IS THE CEILING, NOT THE FLOOR.

Advantages of Multidrug Therapy in
Hypertension
►Increased efficacy of each
drug compared to either as
monotherapy
►More prompt achievement
of goal
►Reduced side effects,
clinical and metabolic
►Alterations in
pharmacodynamics allowing
longer duration of action
Adapted and updated from Black HR. Patient Care, 1997.
►Broader spectrum of
response
►Complementary
mechanisms
of action
►Fewer pills should mean
better adherence
►Fewer co-pays if given as a
fixed dose combination and
often cheaper than buying
each individually
JNC 7: Combination Therapy
►
“When BP is more than 20 mmHg above systolic
goal or 10 mmHg above diastolic goal,
consideration should be given to initiate therapy
with 2 drugs, either as separate prescriptions or
in fixed-dose combinations.”
Hypertension, 2003;42:1221b
Position Statement: Monotherapy
Versus Combination Therapy ESC/ESH
►
►
►
►
►
Regardless of the drug employed, monotherapy allows to
achieve BP target in only a limited number of hypertensive
patients.
Use of more than one agent is necessary to achieve target BP
in the majority of patients. A vast array of effective and well
tolerated combinations is available.
Initial treatment can make use of monotherapy or combination
of two drugs at low doses with a subsequent increase in drug
doses or number, if needed.
Monotherapy could be the initial treatment for a mild BP
elevation with a low or moderate total cardiovascular risk. A
combination of two drugs at low doses should be preferred as
first step treatment when initial BP is in the grade 2 or 3 range
or total cardiovascular risk is high or very high.
Fixed combinations of two drugs can simplify treatment
schedule and favor compliance.

The Vasodilatory Beta Blockers
►
There are two such agents available: carvedilol and nebivolol.
►
Carvedilol causes vasodilation by alpha blockade, nebivolol
by nitric oxide mechanisms.
►
These agents appear to avoid the adverse metabolic effects
observed with older beta blockers.
►
Unlike the original agents, these drugs reduce peripheral
resistance and maintain cardiac output.
►
Nebivolol has been shown to work equally as well in the aorta
as in the brachial artery, but it is not yet known whether this
affects CV outcomes.
►
A major attribute of newer agents like nebivolol is the
avoidance of adverse effects on mood, exercise performance
and sexual activity.

Post-MI Cardiac Remodeling
►
Most common cause of heart failure in post-MI
patients.
►
Likelihood of remodeling increased with larger
infarct size and/or presence of LVD.
►
Patients often remain asymptomatic while
remodeling progresses.
►
Increased LV wall stress and neurohormonal
factors are responsible for remodeling.

were followed in the Enhanced Feedback for Effective Cardiac Treatment (EFFECT) observational study. Use of ACEIs,
ARBs, and -blockers was evaluated at the time of hospital discharge and 90 days postdischarge according to risk for

Which Patients Should Get a β-blocker?
Indications, based upon patients enrolled in the RCTs:
► LVEF <40%.
► Mild to severe symptoms (NYHA FC II–IV); also patients with
asymptomatic LV systolic dysfunction post-MI.
► On optimal dose of an ACEI or/and ARB (and aldosterone antagonist, if
indicated).
► Patients should be clinically stable (e.g. no recent change in dose of
diuretic).
► Cautious, pre-discharge initiation in a recently decompensated patient
provided that the patient has improved with other treatments, is not
dependent on an i.v. inotropic agent, and can be observed in hospital
for at least 24 h after β-blocker initiation.
ESC Guidelines for the diagnosis and treatment of acute and chronic heart failure 2008.
European Heart Journal 2008 29(19):2388-2442.
Initiation of a β-blocker
► Starting dose: bisoprolol 1.25 mg o.d., carvedilol 3.125–6.25 mg b.i.d.,
metoprolol CR/XL 12.5–25 mg o.d., or nebivolol 1.25 mg o.d.—under
supervision in outpatient setting.
► Dose up-titration
► Visits every 2–4 weeks to up-titrate the dose of β-blocker (slower dose
up-titration may be needed in some patients). Do not increase dose if
signs of worsening HF, symptomatic hypotension, or excessive
bradycardia (pulse rate <50/min) at each visit.
► In absence of the above problems, double the dose of β-blocker at each
visit until the evidence-based target dose is reached—bisoprolol 10 mg
o.d., carvedilol 25–50 mg b.i.d., metoprolol CR/XL 200 mg o.d., or
nebivolol 10 mg o.d.—or maximum tolerated dose.

Summary/Conclusions
►
Beta blockers are strongly indicated post-MI and in
all patients with LVD regardless of symptoms.
►
Evidence-based beta blockers should be used at
doses targeted in clinical trials.
►
In-hospital initiation of a beta blocker is an excellent
strategy for increasing utilization.

-Blockers as Initial Agents
Initial Therapy for Hypertension?
In my opinion:
►
►
►
►
-BLOCKERS should be not be used for initial
treatment unless the patient has a compelling or
specific indication.
Diuretics, ACE-I/ARBs and CCBs should be
considered as “TIER 1” drugs and used before BLOCKERS in other patients.
-BLOCKERS should be considered as a common
additional agent to those patients resistant to
properly selected TIER 1 agents.
But…
-Blockers as Initial Therapy for Hypertension?
In my opinion:
►
… we still do not know whether this approach will also apply to
newer cardioselective, vasodilatory -BLOCKERS.
►
Their potential is unknown since they:
►
●
Reduce blood pressure by a more pathophysiologically appropriate
mechanism (maintainance of cardiac output and reduction of total
peripheral resistance) than traditional do traditional -BLOCKERS .
●
Are not likely to have untoward metabolic effects.
●
Increase NO production which has beneficial effects on the
endothelium.
Conclusions: The clinical, hemodynamic and metabolic effects of the
new generation agents are promising. Outcome trials are needed to
clarify how and why our approaches to these agents might be different.

The Ages Of Man
The View Of Those Who Pay For Care
Infants:
Cheap to produce & easy to replace
Young Adults:
Expensive to raise & educate and have not yet

Adult > Age 65:

unproductive & potentially “costly”
individuals to population
