Heart Failure: ACC
Guidelines for Dx and
Management

Epidemiology




Approximately 5 million patients in this country
have HF
Over 550,000 patients are diagnosed with HF for
the first time each year
Primary reason for 12 to 15 million office visits
and 6.5 million hospital days each year
In 2001, nearly 53,000 patients died of HF as a
primary cause
Epidemiology



The incidence of HF approaches 10 per
1000 population after age 65
HF is the most common Medicare
diagnosis-related group
More dollars are spent for the diagnosis
and treatment of HF than any other
diagnosis by Medicare
ACC Guidelines


Focus on :
Prevention of HF
Diagnosis and management of chronic HF
in the adult.
Definition

HF is a complex clinical syndrome that can
result from any structural or functional
cardiac disorder that impairs the ability of
the ventricle to fill with or eject blood.

Because not all patients have volume
overload at the time of initial or
subsequent evaluation, the term “heart
failure” is preferred over the older term
“congestive heart failure.”
• Use terms:


Compensated Heart Failure: euvolemic
Decompensated Heart Failure: fluid overload
Etiology




For a substantial proportion of patients,
causes are:
Coronary artery disease
Hypertension
Dilated cardiomyopathy

New York Heart Association
Classes
NYHA I: no symptoms w/ physical activity,
but known disease
NYHA II: slight limitations, symptoms w/
normal activities, but able to walk 3 blocks
NYHA III: symptoms w. minimal activity and
marked limitation of activity
NYHA IV: symptoms at rest and any activity
Stages of Heart Failure
Designed to emphasize preventability of
HF through treatment therapies.
Designed to recognize the progressive
nature of LV dysfunction.
Stages of HF

COMPLEMENT, DO NOT REPLACE NYHA
CLASSES

NYHA Classes - shift back/forth in individual
patient (in response to Rx and/or
progression of disease)

Stages - progress in one direction due to
cardiac remodeling
Stages of HF

At Risk for Heart Failure:
STAGE A
High risk for developing HF
STAGE B
Asymptomatic LV dysfunction
Heart Failure:
STAGE C
Past or current symptoms of
HF
STAGE D
End-stage HF
Management of Patients with Known
Atherosclerotic Disease But No HF
Treatment with ACE
inhibitors decreases
the risk of CV death,
MI, stroke, or cardiac
arrest.

survival in patients with a history of cardiac
arrest, ventricular fibrillation, or
hemodynamically destabilizing ventricular
tachycardia.
Devices

An ICD for primary prevention to reduce
total mortality by preventing sudden cardiac
death (SCD) in patients with ischemic heart
disease who meet the following criteria: at
least 40 days post-myocardial infarction, an

functional class II or III symptoms despite
optimal chronic medical therapy, and a
reasonable expectation of survival with a
good functional status for more than one
year.


An ICD for primary prevention to reduce
total mortality by preventing SCD in patients
with nonischemic cardiomyopathy who meet
the following criteria: an LVEF less than 30
percent, New York Heart Association

reasonable expectation of survival with a
good functional status for more than one
year.


Cardiac resynchronization therapy,
unless contraindicated, in patients who
meet the following criteria: cardiac
dyssynchrony as defined by a QRS
duration >120 msec, LVEF 35 percent,
