Heart Failure Guidelines
Overview
•
Who is this document primarily intended to reach? What is the format?
•
How soon should I see a newly referred heart failure patient?
•
How often should my heart failure patient be seen?
•
Who can I discharge from my heart failure clinic?
•
How quickly and in what order should standard heart failure therapy be titrated
for most patients?
•
When should I measure electrolytes, serum Creatinine and BUN?
•
How should I manage hyper or hypokalemia in my patients?
•
I know I should get a baseline measure of left ventricular ejection fraction- but
should I measure it again? If so, when should it be measured?
•
Can heart failure medications ever be stopped? If so, then when?
•
How should I manage an acute episode of gout?
•
In what ways do I care differently for frail elderly patients with heart failure?
•
How do I teach self care to my patients?

Case Study
• Mr. M.
• 71 year old man with an ischemic cardiomyopathy.
NYHA III, LVEF 30%.
• COPD, diabetes, chronic renal failure, atrial fibrillation
• Takes 12 different types of medications daily (blister pack)
• Lives alone in an apartment- “lady friend nearby”
• 4 admissions for heart failure in the past year

Are my
symptoms
different
today?
Was that a
good
decision?
Do I feel
better?
What should
I do to relieve
my
symptoms?
Moe GW, Ezekowitz JA et al., Can J Cardiol

I wonder why
my symptoms
changed?
Do I need to
do anything
about my
symptoms?
Self-care Strategies
Patients define self-care not only by the actual performance of tasks but
also by the emotional reactions and strategies necessary for learning
how to adapt to living with HF.
Self-care is a process of learning, and self-care activities are often
intentional, planned, and built on previous experiences.
Individualized approaches that emphasize how to self-care must be
adopted for patients to develop the necessary HF self-care skills.

Harkness et al., 2014 J. Cardiovasc Nurs
“Lay Clinical Trials”: Expert Approach
One patient described her strategy to improve her tolerance to a
medication based on a past experience of symptomatic hypotension that
prevented her from going to work.
She stopped the medication for a few days, reintroduced the medication
at 1/2 the prescribed dose and then slowly titrated the medication
depending on how she felt getting out of bed in the morning.
At the same time, she did not report this to her physician and actually
‘‘lied to him about the dose’’ she was taking, as she was too
embarrassed to disclose her own approach to titrating the medication.

“Lay Clinical Trials”: Good Intentions
• Increasing fluid intake to ‘flush out the system’ to increase diuresis and
improve symptoms
• Choosing Kentucky Fried Chicken rather than Swiss Chalet when
dining out (Swiss Chalet worsens edema)
“I thought I was doing the right thing trying to lose weight, had no idea I
was making my heart problem worse”
Woman trying to lose weight and switched to low fat frozen dinners - but high in sodium

Past Experience
“I don’t take my Lasix when I am going out somewhere, I can’t always get
to a bathroom quick enough. I had an accident when I was out a few
months ago and I was so embarrassed I could have died.’’
“My weight just kept going up - I knew if I gained weight I would need to
go back to the hospital. So I just stopped checking my weight.”
The “catch 22’. She was afraid to call for help, based on past
experiences, that she would call too soon, and so tended to wait until a
crisis to ask for help.

Self-care Tips


Understand patient and caregiver beliefs about HF and its self-care,
their expectations and aspirations for daily life
Harness cues in patients’ home environments and routines to
increase adherence patterns

Plan ahead using a problem-solving approach that for supporting
self-care when usual activities are altered

Involve caregivers - key source of support

Heart Failure Guidelines
Strachan et al., J Cardiac Fail, 2014; Clark et al., BMJ, 2014
Self-care Tips

Personalize Signs and Symptoms- How do you know if you are
starting to retain fluid?

Expect a large variety of vague descriptions from patients/family
caregivers.

Highlight signs or symptoms that reflect HF decompensation.

Help clarify signs and symptoms that are probably not related to
HF.
Moe GW, Ezekowitz JA et al., Can J Cardiol
www.ccs.ca
Heart Failure Guidelines
Self-care Tips

Try to determine the trigger with the patient/family.

Through story telling - pick out the details that seem relevant to
heart failure.

Problem solving and experiential learning versus determining blame
to help prevent feelings of guilt.


Watch for “unintentional non-adherence”
e.g. Restaurant food, holidays, over-the-counter-medications.

Nobody Ever Told Me…
“Teach back” technique
I want to make sure I explained this in a way you could understand…
Can you tell me…
So when you go home to your (family)… how are you going to explain…
 Sometimes the information is not clear to the patient, not 'clicking' with
them, ensure they understand what it is you are explaining.
Moe GW, Ezekowitz JA et al., Can J Cardiol
www.ccs.ca
Heart Failure Guidelines
White et al., J Cardiovasc Nurs. 2013
Difficulty with Self-care
 Some self-care challenges/misunderstandings are the result of minor
cognitive impairment; consider administering a MoCA test
Moe GW, Ezekowitz JA et al., Can J Cardiol
www.ccs.ca
Heart Failure Guidelines
Summary
• Self-care is a skill and needs practice and learning over time.
• Do not expect HF patients to ‘catch on’ to all the necessary instructions
without repetition and reinforcement.
• Teach back techniques help ensure understanding.
• Involvement of family member/caregiver is often necessary.
• ‘Non-adherence’ may be unintentional and represent difficulty with the
level of complexity associated with self-care.
• Consider formal screening for underlying depression or subtle cognitive
impairment in patient who have ongoing challenges with self-care.

• Mrs. Tetley is followed up via telephone 1 week later
– Furosemide and metoprolol were maintained and ramipril 1.25mg BID was
started; other medications were streamlined
– She reports feeling better, but still has some SOBOE and mild peripheral
edema
– Blood work done the day prior reveals:
• SCr = 101 umol/L (was 100 umol/L)
• K = 5.5 mmol/L (was 4.8 umol/L)
• Plan:
– A) Hold ACEI, repeat BW in 3-5 days
– B) Hold ACEI and give sodium polysterene (Kayexalate®), repeat BW in 2
days
– C) Assess dietary intake, ensure K+ supplement was discontinued, repeat

Key Points
• Evidence-based medications (EBM) are a major cornerstone in HF
treatment
• Poor CV outcomes in HF are correlated to
– Underutilization of EBM
– Poor optimization of EBM
– Patient non-adherence and non-persistence to EBM
• Under-intensification of EBM is common and results in poorer
outcomes
• Clinical tools exist to help improve the application of EBM in HF to
front-line practitioners. For example the app can form the underpinning
of a collaborative practice arrangement between
nurses/physicians/pharmacists.

Peripartum Cardiomyopathy
Incidence
• Varies widely geographically, ranging
– United States : 1/2289-1/4000 live births,
– to 1/300 live births in Haiti99.
 We are seeing a lot more cases like Mrs. Doe, than true incidences of
peripartum cardiomyopathy due to: more non-Caucasians, more obesity, and
increased hypertension in pregnancy

How often should my HF patient be seen?
Risk group
Low risk
Features defining risk of group
NYHA Class I or II; No hospitalizations in past year;
No recent changes in medications; On all optimal
medical HF therapies
Intermediate No clear features of high or low risk.
High risk
NYHA IIIb or IV symptoms, frequent symptomatic
hypotension, more than 1 HF admission (or need for
outpatient intravenous therapy) in past year,
recent HF hospitalization esp. in past month, rising
creatinine, especially eGFR < 30 ml/min, Nonadherence to therapy for any reason; During titration of
HF medications (ACEi/BB/ARB/MRA); New onset
heart failure; Complication of HF therapy; Need to
downtitrate or discontinue beta-blockers or ACE/ARB ;
Concomitant and active illness (i.e. high grade angina,
severe COPD, frailty); frequent ICD firings (1 month)
Moe GW, Ezekowitz JA et al., Can J Cardiol
www.ccs.ca
Heart Failure Guidelines
Suggested frequency of follow-up*
At least yearly
(90% suggested within 12 months,
50% within 6 months)
In certain cases, may consider
discharge of patient from clinic to
specialist office (in addition to primary
care).
1-6 months
Minimum 1-2 visit per month
In some cases, there may be weekly
assessments or even more frequentespecially if patient willing to undergo
multiple visits to potentially avoid a
hospitalization.
When should I get another EF Measurement?
Clinical Scenario
Timing of measurement
New Onset Heart Failure Immediately or within 2
weeks for baseline
assessment
Following titration of
3 months after completion
triple therapy for HFrEF, of titration
or consideration of
ICD/CRT implantation
Stable Heart Failure
Approximately every 2-3
years, especially if EF is
above 40%
Following significant
clinical event (i.e.
hospitalization for HF)
ECHO or MUGA or CMR
(preferably the same
modality and lab as initial
test)
ECHO or MUGA or CMRI
Comments
70% request ECHO and
30% MUGA, report
should include numeric
EF or small range of EF
as well as diastolic
function evaluation
LVEF following optimal
medical therapy may
obviate device therapy.
Rationale is to screen for
those who may cross
from HFrEF to HFpEF
and vice versa, which
may change therapeutic
goals
Within 30 days, during
ECHO or MUGA or CMRI, Frequently helpful
hospitalization if possible. cardiac catheterization in information such as EF,
context of ACS
degree of valvular
dysfunction and RVSP.
Moe GW, Ezekowitz JA et al., Can J Cardiol
www.ccs.ca
Modality of
Measurement
ECHO (preferred when
available); or MUGA or
CMRI
Heart Failure Guidelines
 Ejection fractions do not
remain the same foreverthey will change over time,
thus should be checked
periodically (or at least
thought about) as there is no
predefined schedule for EF
measurement

Mrs. Doe Follow Up
• Now asymptomatic
• Diuretic stopped due to hypovolemia
• Repeat ECHO EF 54%
– LV EDD 48 mm
– No MR
– Normal RVSP est but only trivial TR
 Because she is asymptomatic, she starts ‘playing’ with her drugs, and
questions whether she could go off them completely.
Moe GW, Ezekowitz JA et al., Can J Cardiol
www.ccs.ca
Heart Failure Guidelines
Now she wants to stop her HF meds
• Yes or no?
• If so, which ones?
 If EF goes above 40, good prognosis. Thus, for certain conditions you
may be able to stop/discontinue medications if EF returns to normal, or
above 40% (refer to following 2 slides).

Comments
Usually due to atrial fibrillation/flutter with increase
HR, may rarely occur due to PVCs. May need BB for
rate control
Nutritional deficiency may coexist.
May need control of obesity and obstructive sleep
apnea
Certain types of chemo (trastuzamab - high rate of
improvement one it is stopped) are more likely to
reverse than others (anthracyclines for which therapy
should be continued).
Long-term surveillance strongly recommended
Repeat pregnancy may be possible for some(REF
2009); (silversides). Consultation at high-risk
maternal centre should be undertaken.
Less consensus on regurgitant lesions with ongoing
dilation of LV
What is the evidence for drug
withdrawal in HF?
• Almost nil for ACE (however symptoms may return in majority of cases)
• Few studies of BB (show development of symptoms, and recurrence of
phenotypic HF syndrome)
– Several case series of up to 60 patients
– No controls
– No ‘denominator’
• Largest Trial Waagstein 24pts withdrawal
– 66% deteriorated, 4 died
• Morimoto- Japan- 13 patients
– 7 deteriorated, 4 died
• Swedberg, initial paper in 15 DCM
– 40% worsened
• When deterioration occurred, it did so within a few months

Withdrawal of agents
• ACE inhibitors
– Clinical worsening in 70%
– Minor change in EF
– Exception seems to be in renal dysfunction
• Beta Blockers
– In both NICM and ICM
– Odds ratio of return of HF 26 in one study if BB stopped
– About 70% chance of lower EF, often with symptoms
• MRA:
– No real data
• Diuretics
– Increased likelihood of return of symptoms
• PPCM
– Low incidence of HF if EF returned to normal

39 year old male
• Seen last year with A Flutter and LVEF 22%
– Was drinking heavily at time and was hypertensive
• Cardioverted and in NSR since then
• Now LVEF on ACE and BB and OAC is 60%
• Asymptomatic

Tachycardia-Induced Cardiomyopathy
• Caused by persistent supraventricular or ventricular arrhythmias,
especially atrial fibrillation, atrial flutter, atrial tachycardia, junctional
tachycardia, ventricular tachycardia
• May occur at any age
• Should be suspected when LV dysfunction (with or without typical HF
signs/symptoms) occurs with a persistent, inappropriate tachycardia or
tachyarrhythmia, without another identified cause
• Important to exclude inadequately treated HF and other conditions that
may produce a persistent tachycardia

Follow up
• Patient still drinking 2 drinks per day (what he admits to)
• Patient has gained 30 lbs (salesman, travel) and BP is elevated
150/94
• Patients has developed diabetes during the past year

Heart Failure Guidelines
Alcohol-Induced Cardiomyopathy
• Alcohol consumption is a major risk factor for dilated cardiomyopathy
Recommendation
• Permanent abstention from alcohol must be recommended and
reinforced (refer to a counselling program if necessary) in patients
diagnosed with an alcohol-related cardiomyopathy
(Class I, Level C)

Mrs. PP
• 60 year old female presented 1 year ago with breat cancer, HER +
• Underwent FAC and Trastuzamab therapy for 6 months
• 9 month EF showed EF 60 to 44%
• Trastuzamab stopped
• Progressive heart failure 3 months later
• Placed on Ace and BB and diuretic and Trastuzamab stopped

Questions (Y or N)
• Would you stop trastuzamab for good?
• When would you re-check LVEF?
Moe GW, Ezekowitz JA et al., Can J Cardiol

Heart Failure Guidelines
Further Follow-up
• 3 months later LVEF is 55% on therapy
• Do you stop therapy?
– Why or why not?
• How long would you follow if EF stayed normal?

Heart Failure Guidelines
Chemotherapy-Induced Cardiomyopathy
• Most common and severe with anthracyclines and herceptin
Recommendations
• Patients receiving known cardiotoxic agents for cancer should be
carefully monitored during and after therapy. If LV function
deteriorates, they should be aggressively treated with beta-blockers
and other standard therapies for HF
(Class IIa, Level B)
• In patients with a history of chemotherapy-induced cardiomyopathy or
HF, other cancer treatment options should be considered
(Class IIa, Level B)
