8. Heart Failure
• Heart failure is a complex clinical syndrome that results from a
functional or structural heart disorder impairing ventricular filling or
ejection of blood to the systemic circulation.

9. Epidemiology
• According to the Global Health Data Exchange registry, the current
worldwide prevalence of CHF is 64.34 million cases.
• The registry also notes a predilection for race with a 25% higher prevalence of
HF in patients of African-American descent than in Caucasians.
• This translates to 9.91 million years lost due to disability (YLDs) and
346.17 billion US dollars in healthcare expenditure.
• *In a joint assessment release, the Government of Ukraine, the European Commission, and
the World Bank, in cooperation with partners, estimate that the current cost of reconstruction
and recovery in Ukraine amounts to $349 billion.

heart failure with
• reduced ejection fraction (HFrEF)
• Heart failure with improved ejection fraction
• heart failure with preserved ejection fraction (HFpEF)
• heart failure with mid-range ejection fraction (HFmrEF).

14. Type of HF

HFimpEF
Previous LVEF ≤40% and a follow-up measurement of LVEF >40%
HFmrEF
• LVEF 41%–49%
• Evidence of spontaneous or provokable increased LV filling pressures
(e.g., elevated natriuretic peptide, noninvasive and invasive
hemodynamic measurement)

15. NYHA
Class Patient Symptoms
I No limitation of physical activity. Ordinary physical activity does not cause undue fatigue,
palpitation or shortness of breath.
II Slight limitation of physical activity. Comfortable at rest. Ordinary physical activity results
in fatigue, palpitation, shortness of breath or chest pain.
III Marked limitation of physical activity. Comfortable at rest. Less than ordinary activity
causes fatigue, palpitation, shortness of breath or chest pain.
IV Symptoms of heart failure at rest. Any physical activity causes further discomfort.

17. COR LOE Recommendations
1 A
In patients with hypertension, blood pressure should be controlled in accordance
with GDMT for hypertension to prevent symptomatic HF
1 A
In patients with type 2 diabetes and either established cardiovascular disease or at
high cardiovascular risk, SGLT2i should be used to prevent hospitalizations for HF
1 B - NR
In the general population, healthy lifestyle habits such as regular physical activity,
maintaining a normal weight, healthy dietary patterns, and avoiding smoking are
helpful to reduce future risk of HF
2a B - R
For patients at risk of developing HF, natriuretic peptide biomarker–based screening
followed by team-based care, including a cardiovascular specialist optimizing GDMT,
can be useful to prevent the development of LV dysfunction (systolic or diastolic) or
new-onset HF
2a B - NR
In the general population, validated multivariable risk scores can be useful to
estimate subsequent risk of incident HF

18. COR LOE Recommendations
1 A
In patients with LVEF ≤40%, ACEi should be used to prevent symptomatic HF and reduce mortality
1 A
In patients with a recent or remote history of myocardial infarction or acute coronary syndrome, statins
should be used to prevent symptomatic HF and adverse cardiovascular events
1 B - R
In patients with a recent myocardial infarction and LVEF ≤40% who are intolerant to ACEi, ARB should be
used to prevent symptomatic HF and reduce mortality
1 B - R
In patients with a recent or remote history of myocardial infarction or acute coronary syndrome and LVEF
≤40%, evidence-based beta blockers should be used to reduce mortality
1 B - R
In patients who are at least 40 days post–myocardial infarction with LVEF ≤30% and NYHA class I symptoms
while receiving GDMT and have reasonable expectation of meaningful survival for >1 year, an ICD is
recommended for primary prevention of sudden cardiac death to
reduce total mortality
1 C - LD

beneficial to reduce morbidity and mortality when the use of ARNi is not feasible
1 B - R
In patients with chronic symptomatic HFrEF NYHA class II or III who tolerate an ACEi or
ARB, replacement by an ARNi is recommended to further reduce morbidity and
mortality
1 A
In patients with HFrEF, with current or previous symptoms, use of 1 of the 3 beta
blockers proven to reduce mortality is recommended to reduce mortality and
hospitalizations
1 A
In patients with HFrEF and NYHA class II to IV symptoms, an MRA is recommended to
reduce morbidity and mortality, if eGFR >30 mL/min/

26. Level Statements
High In patients with previous or current symptoms of chronic HFrEF, in whom ARNi is not feasible, treatment
with an ACEi or ARB provides high economic value
High In patients with chronic symptomatic HFrEF, treatment with an ARNi instead of an ACEi provides high
economic value
High In patients with HFrEF, with current or previous symptoms, beta-blocker therapy provides high economic
value
High In patients with HFrEF and NYHA class II to IV symptoms, MRA therapy provides high economic value
High

medical therapy with ACEi or ARB, beta blockers, and MRA, the combination of hydralazine and isosorbide
dinitrate provides high economic value

A transvenous ICD provides high economic value in the primary prevention of sudden cardiac death
particularly when the patient’s risk of death caused by ventricular arrythmia is deemed high and the risk of
nonarrhythmic death is deemed low based on the patient’s burden of comorbidities and functional status
High For patients who have LVEF ≤35%, sinus rhythm, LBBB with a QRS duration of ≥150 ms, and NYHA class II,
III, or ambulatory IV symptoms on GDMT, CRT implantation provides high economic value

28. Mechanical Circulatory Support
• Refractory Stage D HFrEF/ NYHA Class IV
• Dependent on Inotropes.
• Bridge to transplant.

29. Cardiac Transplant
• Patients with progressive HF or those with acute, severe refractory HF
may be considered for heart transplantation.

30. Prognosis
• The mortality rate following hospitalization for heart failure is
estimated at around
• 10% at 30 days
• 22% at 1 year
• 42% at 5 years.
• This can increase to greater than 50% for patients with NYHA class IV, stage D heart
failure.

33. Enhancing Team Outcomes
• Heart failure is a complex clinical syndrome with high morbidity and
mortality. It requires a multifaceted treatment approach, including
patient education, pharmacologic management, and surgical
interventions to optimize clinical outcomes.
• A collaborative interprofessional team can greatly improve the quality
of life for patients with HF and decrease mortality.
