
Discuss reduced ejection fraction(HFrEF)
and preserved ejection fraction (HFpEF)
heart failure

Examine the role and recommendations of
exercise training in heart failure (HF)

Identify barriers and strategies to
overcome these barriers in the HF
population
Objectives


The definition of HF has now expanded to:
a. HF with reduced ejection fraction
(HFrEF, EF≤40%)
b. HF failure with preserved ejection fraction
(HFpEF EF ≥50%)
c. HFpEF, borderline (EF 41-49%)
d. HFpEF, improved (EF >40%)
Two Types of HF
Definition of Heart Failure
Classification
I. Heart Failure with
Reduced Ejection Fraction
(HFrEF)
Ejection
Fraction
≤40%
Description
Also referred to as systolic HF. Randomized clinical trials have
mainly enrolled patients with HFrEF and it is only in these patients
that efficacious therapies have been demonstrated to date.
≥50%
Also referred to as diastolic HF. Several different criteria have been
used to further define HFpEF. The diagnosis of HFpEF is
challenging because it is largely one of excluding other potential
noncardiac causes of symptoms suggestive of HF. To date,
efficacious therapies have not been identified.
a. HFpEF, Borderline
41% to 49%
These patients fall into a borderline or intermediate group. Their
characteristics, treatment patterns, and outcomes appear similar to
those of patient with HFpEF.
b. HFpEF, Improved
>40%
It has been recognized that a subset of patients with HFpEF
previously had HFrEF. These patients with improvement or recovery
in EF may be clinically distinct from those with persistently
preserved or reduced EF. Further research is needed to better
characterize these patients.
II. Heart Failure with
Preserved Ejection
Fraction (HFpEF)
ACCF/AHA 2013 HF Guidelines JAC 2013 5 June (E-Pub online)

The number of patients with HF, as well as the cost to treat
patients with HF, is expected to increase in the future.

All causes of HF must be evaluated, with consideration of
multigenerational family histories and genetic testing.

Risk factors need to be continually addressed when
managing a patient with HF: hypertension, lipid disorders,
obesity, diabetes mellitus, tobacco use, and known
cardiotoxic agents.

There is a clear mortality benefit from using guidelinedirected medical therapy.
Important points regarding HF
management

Anticoagulation should not be used in patients with chronic HFrEF
with no risk factors (atrial fibrillation, thromboembolic event, or
cardioembolic source).

Aim for control of systolic and diastolic blood pressures, as well
as volume status, to treat HFpEF.

Re-evaluate patients with left ventricular EF ≤35%, New York
Heart Association class II-IV, left bundle branch block, and a QRS
≥150 ms for cardiac resynchronization therapy.

HF education, dietary restrictions, and exercise training should
be provided for all patients to enhance self-care.

A HF multidisciplinary team, including a palliative care team,
should be involved when treating patients with advanced HF.

Current Guidelines 2013:
◦ Class I
 Exercise training (or regular physical activity) is
recommended as safe and effective for patients
with HF who are able to participate to improve
functional status
(Level of Evidence: A)
◦ Class IIa
 Cardiac rehabilitation can be useful in clinically
stable patients with HF to improve functional
capacity, exercise duration, HRQOL, and mortality.
(Level of Evidence: B)
Role of Exercise Training in HF

Three major risk factors: age, presence
of heart disease and intensity of
exercise
◦ Lowest incidence: walking, cycling and
treadmill walking
◦ Least active patients are higher risk
◦ In HF patients, most common events
include: post-exercise hypotension,
atrial and ventricular arrhythmias and
worsening HF symptoms

“My Doctor said if I hadn’t been in such good physical
shape from swimming it very likely would have been a fatal
heart attack. Swimming or any kind of exercise saves
lives”.
Find strategies to get patients referred
and enrolled in your cardiac rehabilitation
program
 Use this opportunity to give disease
specific education to the HF patients
 Prescribing exercise for HF patients is
similar to patients without HF
 Partner with your providers to help keep
these patients out of the hospital with
close surveillance of their symptoms.
